Hypothesis:
Testing the effectiveness of bacteria killing agents

Prosedure:

1. Prepared petri dishes should be refrigerated until used and always stored upside down (i.e media in upper dish, cover on bottom). This keeps condensation which forms in the lid from dropping onto and disrupting the bacteria growing surface.

2. Prepare sterilized water by boiling water and letting cool to room temperature.

3. When ready to use, let petri dishes come to room temperature before taking samples (about one hour).

4. Prepare antiseptic disks by using a hole punch to create paper disks out of a piece of filter paper or paper towel. Soak one disk in each antibacterial agent to be tested. Set aside until step 6.

5. Collect bacteria from each location using one swab for each new spot.

6. Fill a small test tube partly full of sterilized water. Dip bacteria laden swab into water. This will transfer some of the bacteria you collected into the water. Now, inoculate a petri dish by pouring the water into the dish so the entire surface is covered. Pour out excess water. Repeat for each bacteria sample using fresh water and clean test tube each time.

7. Place a pretreated antiseptic disk in each inoculated petri dish.

8. Replace cover on dish, tape closed, store upside down. Be sure to label each petri dish with a name or number.

9. Let grow in undisturbed warm location, ideally in an environment around 100° F (37° C) - not in sunlight or on a heating register.

10. You should see growth within a couple of days. You should also see a "halo" around each disk indicating a no growth zone. Measure and compare the size of the kill zone to determine effectiveness of each antibacterial agent.

11. Before disposing of dishes in the trash the bacteria should be destroyed. Pour a small amount of household bleach over the colonies while holding dish over sink. Caution - do not allow bleach to touch your skin, eyes or clothes. It will burn!

Hypothesis: Money affects the honesty value in most people.

Procedure: 
1. Prepare a money note such as Rm 10 and mark a dot to make sure that the note can be proven its ours.
2. Set up a camera from an angle that cannot be seen and wait for people to pass by that area.
3. Approach a random person from behind can pretend to pick up the money note which is already in your palm.
4. Tap the shoulder of the random person and ask him or her whether that money note belongs to them.
5. See their respond whether that they say that the money note belongs to them or not.
6. If their respond is yes, then it proves that they are not honest as it practically is not their money because that money note has a dot mark proving its ours.
7. If their respond is no, then it proves that they are being honest as they no its not their money and they will not take something that does not belong to them.
8. Therefore, there will definitely be people who will take the money although it does not belong to them as they are greedy and hungry for money, making their honest value be affected.
9. This proves that money can affect someone's honesty value.

Hypothesis: Make your own rock candy

Procedure:

Clip the wooden skewer into the clothespin so that it hangs down inside the glass and is about 1 inch (2.5 cm) from the bottom of the glass. (as shown)
Remove the skewer and clothespin and put them aside for now.
Get a helpful adult!
Pour the water into a pan and bring it to boil.
Pour about 1/4 cup of sugar into the boiling water, stirring until it dissolves.
Keep adding more and more sugar, each time stirring it until it dissolves, until no more will dissolve. This will take time and patience and it will take longer for the sugar to dissolve each time. Be sure you don’t give up too soon. Once no more sugar will dissolve, remove it from heat and allow it to cool for at least 20 minutes.
Have your friendly ADULT carefully pour the sugar solution into the jar almost to the top. Then submerge the skewer back into the glass making sure that it is hanging straight down the middle without touching the sides.
Allow the jar to fully cool and put it someplace where it will not be disturbed.
Now just wait. The sugar crystals will grow over the next 3-7 days.

Hypothesis : The bouncy ball can be bounced over a foot high and the ball has quite a unique to feel it.

Procedure:
Label one cup ‘Borax Solution’ and the other cup ‘Ball Mixture’.
Pour 4 ounces (120ml) of warm water into the cup labeled ‘Borax Solution’ and 1 teaspoon of the borax powder into the cup. Stir the mixture to dissolve the borax.
Pour 1 tablespoon of glue into the cup labeled ‘Ball Mixture’. Add 3-4 drops of food coloring, if desired.
Add 1/2 teaspoon of the borax solution you just made and 1 tablespoon of cornstarch to the glue. Do not stir.
Allow the ingredients to interact on their own for 10-15 seconds and then stir them together to fully mix.
Once the mixture becomes impossible to stir, take it out of the cup and start molding the ball with your hands. The ball will start out sticky and messy, but will solidify as you knead it. Once the ball is less sticky, continue rolling between your hands until it is smooth and round!

Hypothesis: A bone can be bended by using vinegar.

Procedure:
1. Have a nice chicken dinner and save a bone. Leg bones work best.
2. Rinse off the bone in running water to remove any meat from the bone.
3. Notice how hard the bone is – gently try bending it. Like our bones, chicken bones have a mineral called calcium in them to make them hard.
4.Put the bone into the jar and cover the bone with vinegar. It might be a good idea to put the lid on the jar or cover it – let it sit for 3 days
5. After 3 days remove the bone. It should feel different. Now can rinse it off and try bending it again.

Hypothesis: Egg can float on the high concentrate of salt water.

Procedure: 
 
Carefully place the egg into the glass of water.

Initially the egg will sink to the bottom.

Pour in two teaspoons of salt and stir carefully around the egg.

Continue to add the salt and stir until the egg rises.

Eventually the egg will float as salt water is denser than fresh water and the egg will weigh less than the water.

 Hypothesis: increasing the temperature increases the rate of evaporation of water
steps:
1)the temperature increases which causes the molecules to move faster and more vigorously and increases the kinetic energy of the molecules .
2)the molecules with the higher temperature will escape to the surface and then evaporates.
3) if the water is in room temperature the molecules will stay stable 
4)so the molecules will not escape to the surface because it wont have kinetic energy and its not going to evaporate

Hypothesis : The presence of yeast will affect the expansion of balloon.

Steps:
1. Fill the bottle up with about one inch of warm water.
( When yeast is cold or dry the micro organisms are resting.)
2. Add all of the yeast packet and gently swirl the bottle a few seconds.
(As the yeast dissolves, it becomes active – it comes to life! Don’t bother looking for movement, yeast is a microscopic fungus organism.)
3. Add the sugar and swirl it around some more.
Like people, yeast needs energy (food) to be active, so we will give it sugar. Now the yeast is “eating!”

4. Blow up the balloon a few times to stretch it out then place the neck of the balloon over the neck of the bottle.
5. Let the bottle sit in a warm place for about 20 minutes
If all goes well the balloon will begin to inflate!

Hypothesis:
The balloon become bigger.
Steps:
Carefully pour the vinegar into the bottle.
This is the tricky part: Loosen up the balloon by stretching it a few times and then use the funnel to fill it a bit more than half way with baking soda. If you don’t have a funnel you can make one using the paper and some tape.
Now carefully put the neck of the balloon all the way over the neck of the bottle without letting any baking soda into the bottle.
 Lift the balloon up so that the baking soda falls from the balloon into the bottle and mixes with the vinegar. Watch the fizz-inflator at work!

Hypothesis: The longer the length of a simple pendulum, the longer the period of oscillation 
Steps: 
The thread is tied to the pendulum bob. The other end of the thread is tied around the arm of the retort stand so that it can swing freely. The length of the pendulum, l is measured to 80 cm as per the diagram.
With the thread taut and the bob at rest, the bob is lifted at a small amplitude (of not more than 10°). Ensure that the pendulum swings in a single plane.
The time for ten complete oscillations of the pendulum is measured using the stopwatch.
Step 3 is repeated, and the average of both readings are calculated.
The period of oscillation, T is calculated using the average reading divided by the number of oscillations, i.e. 10.
T2 is calculated by squaring the value of T.
Steps 1 to 6 are repeated using l = 70 cm, 60 cm, 50 cm, and 40 cm.
A graph T2 versus l is plotted.

Hypothesis: Volcanic clay mask actually works in tightening skin pores.

1)      Randomly select a large number of people from the whole population who has big pores
2)      Randomly divide them into 2 groups; an experimental group and a control group.
3)      Treat the two groups exactly the same (giving skin treatment using masks) except that I give the experimental group treatments with volcanic clay mask and I give the control group a placebo, that is, regular clay masks that do not have anything beneficial to pores and skin.
4)      Conduct the study double-blind. That is, I make sure that neither the dermatologists nor the subjects know which of the subjects is getting the volcanic clay mask and which is getting the placebo.
5)      The experiment was handled for 2 weeks and the subjects were not allowed to use any other skincare products to actually see if the volcanic clay mask works.
6)      After two weeks, the progress of subjects’ skins were examined. If the experimental group skins’ pores are tighten and the skins’ condition were better than the controlled group, it can be concluded that volcanic clay mask actually helps in tightening skin pores.

Hypothesis : Plants grow healthily in a complete Knop's solution.
Steps :
1) Randomly select 40 maize seedlings regardless of seedlings' size and species and divide them into Group A and Group B.
2) Place the maize seedlings into glass jars which are connected to an air pump to provide aeration to the roots so that respiration can take place.
3) Fill the jars of Group A with Knop's solution without magnesium and Group B with complete Knop's solution (Containing all the nutrients needed by plants).
4) Wrap the glass jars with black paper to prevent the growth of green algae which will deplete the nutrient content and affect the experiment.
5) Replace both solutions every week to replenish the nutrients absorbed by the maize seedlings.
6) Treat both groups exactly the same in terms of the volume of solutions given, place of experiment and etc except for the type of Knop's solutions
7) Record all observations on the growth of each plants in both groups after one month.

Do a experiment for study
1) a good student come in the last class
2) everyone in the last class was lazy and do their own things, didn’t want to listen to the teacher 
3) the good student will felt uncomfortable for being good and start to being bad to get in that last class 
4) at last, the good student becomes a bad student just like other 
This experiment show that a person would felt uncomfortable when other people act not like them. He will try to act like them although he thinks that he and the other are doing the wrong things. But, he want to be same with other, so he also done the wrong things

Hypothesis : The bouncy ball can be bounced over a foot high and the ball has quite a unique to feel it.

Procedure:
Label one cup ‘Borax Solution’ and the other cup ‘Ball Mixture’.
Pour 4 ounces (120ml) of warm water into the cup labeled ‘Borax Solution’ and 1 teaspoon of the borax powder into the cup. Stir the mixture to dissolve the borax.
Pour 1 tablespoon of glue into the cup labeled ‘Ball Mixture’. Add 3-4 drops of food coloring, if desired.
Add 1/2 teaspoon of the borax solution you just made and 1 tablespoon of cornstarch to the glue. Do not stir.
Allow the ingredients to interact on their own for 10-15 seconds and then stir them together to fully mix.
Once the mixture becomes impossible to stir, take it out of the cup and start molding the ball with your hands. The ball will start out sticky and messy, but will solidify as you knead it. Once the ball is less sticky, continue rolling between your hands until it is smooth and round!

Hypothesis :  The more the amount  of baking soda or vinegar is added, the higher the eruption of the baking soda volcano. 

Procedure:
First, make the 'cone' of the baking soda volcano. Mix 6 cups flour, 2 cups salt, 4 tablespoons cooking oil, and 2 cups of water. The resulting mixture should be smooth and firm (more water may be added if needed).
Stand the soda bottle in the baking pan and mold the dough around it into a volcano shape. Don't cover the hole or drop dough into it.
Fill the bottle most of the way full with warm water and a bit of red food color (can be done before sculpting if you don't take so long that the water gets cold).
Add 6 drops of detergent to the bottle contents. The detergent helps trap the bubbles produced by the reaction so you get better lava.
Add 2 tablespoons baking soda to the liquid.
Slowly pour vinegar into the bottle. Watch out - eruption time!
Conclusion: Hypothesis is accepted.

Hypothesis: A bone can be bended by using vinegar.

Procedure:
1. Have a nice chicken dinner and save a bone. Leg bones work best.
2. Rinse off the bone in running water to remove any meat from the bone.
3. Notice how hard the bone is – gently try bending it. Like our bones, chicken bones have a mineral called calcium in them to make them hard.
4.Put the bone into the jar and cover the bone with vinegar. It might be a good idea to put the lid on the jar or cover it – let it sit for 3 days
5. After 3 days remove the bone. It should feel different. Now can rinse it off and try bending it again.

Hypothesis: Egg can float on the high concentrate of salt water.

Procedure: 
 
Carefully place the egg into the glass of water.

Initially the egg will sink to the bottom.

Pour in two teaspoons of salt and stir carefully around the egg.

Continue to add the salt and stir until the egg rises.

Eventually the egg will float as salt water is denser than fresh water and the egg will weigh less than the water.

Hypothesis : 
The longer time taken for the methylene blue solution to decolourize, the less polluted the water source is. 

Steps : 
Water samples are collected from four different sources
 (tap water, river water, pond water and drain water) and distilled water is used as a control.
Five reagent bottles are labelled as A, B, C, D and E respectively.
Each reagent bottle is filled with the following water sample. 
1ml of methylene blue solution is added by using a syringe to the base of each water sample  in each reagent bottle. 
Each reagent bottle is then closed quickly with a stopper.
The reagent bottle cannot be shaken.
Each reagent bottle is kept in a dark place (cupboard) and then the stopwatch is started.
The bottles are examined from time to time.
The time taken for methylene blue to decolorize is recorded.

 Hypothesis: increasing the temperature increases the rate of evaporation of water
steps:
1)the temperature increases which causes the molecules to move faster and more vigorously and increases the kinetic energy of the molecules .
2)the molecules with the higher temperature will escape to the surface and then evaporates.
3) if the water is in room temperature the molecules will stay stable 
4)so the molecules will not escape to the surface because it wont have kinetic energy and its not going to evaporate

Hypothesis : The presence of yeast will affect the expansion of balloon.

Steps:
1. Fill the bottle up with about one inch of warm water.
( When yeast is cold or dry the micro organisms are resting.)
2. Add all of the yeast packet and gently swirl the bottle a few seconds.
(As the yeast dissolves, it becomes active – it comes to life! Don’t bother looking for movement, yeast is a microscopic fungus organism.)
3. Add the sugar and swirl it around some more.
Like people, yeast needs energy (food) to be active, so we will give it sugar. Now the yeast is “eating!”

4. Blow up the balloon a few times to stretch it out then place the neck of the balloon over the neck of the bottle.
5. Let the bottle sit in a warm place for about 20 minutes
If all goes well the balloon will begin to inflate!

Steps:
Carefully pour the vinegar into the bottle.
This is the tricky part: Loosen up the balloon by stretching it a few times and then use the funnel to fill it a bit more than half way with baking soda. If you don’t have a funnel you can make one using the paper and some tape.
Now carefully put the neck of the balloon all the way over the neck of the bottle without letting any baking soda into the bottle.
 Lift the balloon up so that the baking soda falls from the balloon into the bottle and mixes with the vinegar. Watch the fizz-inflator at work!

Hypothesis: Volcanic clay mask actually works in tightening skin pores.

1)      Randomly select a large number of people from the whole population who has big pores
2)      Randomly divide them into 2 groups; an experimental group and a control group.
3)      Treat the two groups exactly the same (giving skin treatment using masks) except that I give the experimental group treatments with volcanic clay mask and I give the control group a placebo, that is, regular clay masks that do not have anything beneficial to pores and skin.
4)      Conduct the study double-blind. That is, I make sure that neither the dermatologists nor the subjects know which of the subjects is getting the volcanic clay mask and which is getting the placebo.
5)      The experiment was handled for 2 weeks and the subjects were not allowed to use any other skincare products to actually see if the volcanic clay mask works.
6)      After two weeks, the progress of subjects’ skins were examined. If the experimental group skins’ pores are tighten and the skins’ condition were better than the controlled group, it can be concluded that volcanic clay mask actually helps in tightening skin pores.

Hypothesis: Money affects the honesty value in most people.

Procedure:
1. Prepare a money note such as Rm 10 and mark a dot to make sure that the note can be proven its ours.
2. Set up a camera from an angle that cannot be seen and wait for people to pass by that area.
3. Approach a random person from behind can pretend to pick up the money note which is already in your palm.
4. Tap the shoulder of the random person and ask him or her whether that money note belongs to them.
5. See their respond whether that they say that the money note belongs to them or not.
6. If their respond is yes, then it proves that they are not honest as it practically is not their money because that money note has a dot mark proving its ours.
7. If their respond is no, then it proves that they are being honest as they no its not their money and they will not take something that does not belong to them.
8. Therefore, there will definitely be people who will take the money although it does not belong to them as they are greedy and hungry for money, making their honest value be affected.
9. This proves that money can affect someone's honesty value.

Hypothesis : The bouncy ball can be bounced over a foot high and the ball has quite a unique to feel it.

Procedure:
Label one cup ‘Borax Solution’ and the other cup ‘Ball Mixture’.
Pour 4 ounces (120ml) of warm water into the cup labeled ‘Borax Solution’ and 1 teaspoon of the borax powder into the cup. Stir the mixture to dissolve the borax.
Pour 1 tablespoon of glue into the cup labeled ‘Ball Mixture’. Add 3-4 drops of food coloring, if desired.
Add 1/2 teaspoon of the borax solution you just made and 1 tablespoon of cornstarch to the glue. Do not stir.
Allow the ingredients to interact on their own for 10-15 seconds and then stir them together to fully mix.
Once the mixture becomes impossible to stir, take it out of the cup and start molding the ball with your hands. The ball will start out sticky and messy, but will solidify as you knead it. Once the ball is less sticky, continue rolling between your hands until it is smooth and round!

Hypothesis: A bone can be bended by using vinegar.

Procedure:
1. Have a nice chicken dinner and save a bone. Leg bones work best.
2. Rinse off the bone in running water to remove any meat from the bone.
3. Notice how hard the bone is – gently try bending it. Like our bones, chicken bones have a mineral called calcium in them to make them hard.
4.Put the bone into the jar and cover the bone with vinegar. It might be a good idea to put the lid on the jar or cover it – let it sit for 3 days
5. After 3 days remove the bone. It should feel different. Now can rinse it off and try bending it again.

Hypothesis: Egg can float on the high concentrate of salt water.

Procedure: 
 
Carefully place the egg into the glass of water.

Initially the egg will sink to the bottom.

Pour in two teaspoons of salt and stir carefully around the egg.

Continue to add the salt and stir until the egg rises.

Eventually the egg will float as salt water is denser than fresh water and the egg will weigh less than the water.

 Hypothesis: increasing the temperature increases the rate of evaporation of water
steps:
1)the temperature increases which causes the molecules to move faster and more vigorously and increases the kinetic energy of the molecules .
2)the molecules with the higher temperature will escape to the surface and then evaporates.
3) if the water is in room temperature the molecules will stay stable 
4)so the molecules will not escape to the surface because it wont have kinetic energy and its not going to evaporate

Hypothesis : The presence of yeast will affect the expansion of balloon.

Steps:
1. Fill the bottle up with about one inch of warm water.
( When yeast is cold or dry the micro organisms are resting.)
2. Add all of the yeast packet and gently swirl the bottle a few seconds.
(As the yeast dissolves, it becomes active – it comes to life! Don’t bother looking for movement, yeast is a microscopic fungus organism.)
3. Add the sugar and swirl it around some more.
Like people, yeast needs energy (food) to be active, so we will give it sugar. Now the yeast is “eating!”

4. Blow up the balloon a few times to stretch it out then place the neck of the balloon over the neck of the bottle.
5. Let the bottle sit in a warm place for about 20 minutes
If all goes well the balloon will begin to inflate!

Hypothesis:
The balloon become bigger.
Steps:
Carefully pour the vinegar into the bottle.
This is the tricky part: Loosen up the balloon by stretching it a few times and then use the funnel to fill it a bit more than half way with baking soda. If you don’t have a funnel you can make one using the paper and some tape.
Now carefully put the neck of the balloon all the way over the neck of the bottle without letting any baking soda into the bottle.
 Lift the balloon up so that the baking soda falls from the balloon into the bottle and mixes with the vinegar. Watch the fizz-inflator at work!

Hypothesis: Gases expand when heated.
Steps :
Use a pair of scissors to make a hole in the top of the bottle lid, big enough for the drinking straw to fit through.
Fill the bottle halfway with cold water.
Add a few drops of food colouring and mix.
Screw on the bottle lid and insert the straw through it into the water, making sure that the straw does not touch the base of the bottle.
Seal around the hole in the lid using play dough, thereby fixing the straw in place. The seal must be completely airtight.

Hypothesis : Using artificial light will affect the growth on plant.

Put potting soil into the 2 plant pots, and bury a bean seed under half an inch of soil in each pot.
Mist the soil gently so that the beans have water.
Place 1 plant in a box.
Put the light bulb in the desk lamp.
Place the lamp over the box so that the light does not escape from the box. Make sure that it is not touching any paper!
Turn the light on every morning and turn  off every evening.
Place your second bean seed in a sunny window. Make sure that the soil stays damp, but not too wet.
After a week, you will likely see a sprout coming out of the soil. Wait for another week or more, then turn on the light in the room and take a photo of each bean plant. Label the photos with the type of light the plant received. 
Wait for two weeks or more, then take a photo of each plant and observe what has happen to each plant

Hypothesis: Volcanic clay mask actually works in tightening skin pores.

1)      Randomly select a large number of people from the whole population who has big pores
2)      Randomly divide them into 2 groups; an experimental group and a control group.
3)      Treat the two groups exactly the same (giving skin treatment using masks) except that I give the experimental group treatments with volcanic clay mask and I give the control group a placebo, that is, regular clay masks that do not have anything beneficial to pores and skin.
4)      Conduct the study double-blind. That is, I make sure that neither the dermatologists nor the subjects know which of the subjects is getting the volcanic clay mask and which is getting the placebo.
5)      The experiment was handled for 2 weeks and the subjects were not allowed to use any other skincare products to actually see if the volcanic clay mask works.
6)      After two weeks, the progress of subjects’ skins were examined. If the experimental group skins’ pores are tighten and the skins’ condition were better than the controlled group, it can be concluded that volcanic clay mask actually helps in tightening skin pores.

Do a experiment for study
1) a good student come in the last class
2) everyone in the last class was lazy and do their own things, didn’t want to listen to the teacher 
3) the good student will felt uncomfortable for being good and start to being bad to get in that last class 
4) at last, the good student becomes a bad student just like other 
This experiment show that a person would felt uncomfortable when other people act not like them. He will try to act like them although he thinks that he and the other are doing the wrong things. But, he want to be same with other, so he also done the wrong things

Hypothesis : The bouncy ball can be bounced over a foot high and the ball has quite a unique to feel it.

Procedure:

1. Label one cup ‘Borax Solution’ and the other cup ‘Ball Mixture’.

2. Pour 4 ounces (120ml) of warm water into the cup labeled ‘Borax Solution’ and 1 teaspoon of the borax powder into the cup. Stir the mixture to dissolve the borax.

3. Pour 1 tablespoon of glue into the cup labeled ‘Ball Mixture’. Add 3-4 drops of food coloring, if desired.

4. Add 1/2 teaspoon of the borax solution you just made and 1 tablespoon of cornstarch to the glue. Do not stir.

5. Allow the ingredients to interact on their own for 10-15 seconds and then stir them together to fully mix.

6. Once the mixture becomes impossible to stir, take it out of the cup and start molding the ball with your hands. The ball will start out sticky and messy, but will solidify as you knead it. Once the ball is less sticky, continue rolling between your hands until it is smooth and round!
