Does the amount of H2O affect number of seeds germinated

# data[].attributes.body
Hypothese

Amount of H20 will not affect # of seeds germinated.

Amount of H20 will affect # of seeds germinated.

Procedure

1. Place filter paper in petri dish

2. measure and pour 5, 10, 15,and 20 milllileters into the respective dishes

3. put in 10 seed evenly spaced apart

4. place dish on window sill for 72 hours

5. record results

# data[].attributes.body
The amount of water affects the number of seeds germinated. This is shown in our data table with the difference between the number of seeds germinated with 5 milliliters of water and 10. The class average for 5 was 4 seeds germinated, and for 10, 8.7 seeds germinated. This is because water softens the shell of the seed giving the embryo room to grow. It also gives the plant oxygen and activates enzymes that are needed for respiration, the process that makes the plants energy.

Does water affect the amount of isopods in the choice chamber?

Does water affect the amount of isopods in the choice chamber?

# data[].attributes.body
Hypotheses

The moisture levels don't affect the number of isopods in the choice chamber.

The moisture levels do effect the number of isopods in the choice chambers.

Procedure

1. put dry paper in one chamber and wet the paper in the other

2. put five isopods in each chamber

3. close the chamber lids

4. watch and record the number in each chambers in 10 minutes

# data[].attributes.body
The moisture levels don't affect the number of isopods in the choice chambers. In the class data, the average for isopods in the wet chamber was 4.78, and in the dry, it was 5.22, but the error bars were around 3-6 for both of them. This means that we treat the same statistically.

Does acid levels effect the number of isopods in each chamber?

# data[].attributes.subject
Does acid levels effect the number of isopods in each chamber?

# data[].attributes.body
Hypotheses

The acid levels will affect the number of isopods in each chamber.

The acid levels will not affect the number of isopods in each chamber.

Procedure

1. Put equal-sized pieces of paper on each side of the isopod chamber.

2. Put water on one side until the paper is completely wet and no more than that.

3. Put vinegar on the other side until the paper is completely wet and no more than that.

4. put 5 isopods on each side of the chamber

5. watch and record where they go fo r the next 10 minutes

# data[].attributes.body
The acid levels do effect the number of isopods in the choice chambers. The average number in the acidic chamber was 2.9, and the average number for the waterside was 6.9. This is likely because they live in damp and humid environments and have gills that need to be kept wet.

Does nutrient levels effect the growth of duckweed.

# data[].attributes.subject
Does nutrient levels effect the growth of duckweed.

# data[].attributes.body
Hypotheses

The nutrient levels don't affect duckweed growth.

The nutrient levels do affect duckweed growth.

Procedure

1. get four keeps

2. fill each to 125mil

3. transfer 10 duckweed per cup

4. add each keeps the amount of fertilizer

5. let each cup sit on the window sill for 9 days while growth is tracked.

# data[].attributes.body
The nutrient levels increase duckweed growth because it contains nitrates and phosphates. Over the entire experiment, 0 drops increased from 10 duckweed to 12 while 15 drops increased more than double, starting also at 10 and ending with 35. This is due to the Nitrates and phosphates in the fertilizer. Nitrogen is needed to start the growth, and phosphates are needed for developing flowers, fruits, and root systems. This is what caused the increase in growth.

Does the proximity to water effect biodiversity of insects?

# data[].attributes.subject
Does the proximity to water effect biodiversity of insects?

# data[].attributes.body
Hypothesis

The proximity to water will affect the biodiversity of the bugs.

The proximity to water won't affect the biodiversity of bugs.

Procedure

1. set bug traps out in different proximity to the water.

2. Let the bugtraps sit for a day.

3. go collect the bug traps.

4. count the number of bugs in each species.

5. Calculate the Simpsons biodiversity index.

# data[].attributes.body
Proximity to water increases the biodiversity of insects because bugs rely on water for egglaying and drinking. In the experiment, we found that the hill farthest away from the water, the hill had a Simpsons Diversity Index of .46, while the marsh close to the water had a .75. This is because the bugs need plants to survive, and plants rely on the water for photosynthesis. This is a process in which the water makes it own food.

Does light effect carbon levels in a contanier of spinach?

# data[].attributes.subject
Does light effect carbon levels in a contanier of spinach?

# data[].attributes.body
Hypothesis

Light does affect carbon levels.

Light doesn't affect carbon levels.

Procedure

1. Put 20 spinach leaves in a jar.

2. Put the carbon detector in the jar.

3. leave on the window sill for 5 minutes and record findings.

4. Repeat with the different versions, including no light and no spinach.

# data[].attributes.body
Light decreases the amount of carbon in a jar of spinach because of photosynthesis. We saw this when the leaves in the dark increased carbon by 723 and the leaves in light decreased carbon by 422. This is because plants need light and carbon to do photosynthesis, and they produce oxygen in return.

Does germination affect the rate of respiration?

# data[].attributes.subject
Does germination affect the rate of respiration?

# data[].attributes.body
Hypothesis

Germination will affect the rate of respiration.

Germination will not affect the rate of respiration.

Procedure

1. put 25 dormant seeds in a jar.

2. track their carbon levels over 8 minutes.

3. repeat with germinated seeds.

4. analyze the data.

# data[].attributes.body
Germination in seeds increases respiration because of cell-building activities. This was seen in the experiment when both the carbon dioxide levels in the germinated and ungerminated seed containers started at around 410 and germinated increased to 529 while ungerminated only increased to 477. This is seen because cellular respiration gives the plant energy. While the plant is ungerminated, it is entirely asleep because it doesn't need to do anything other than stay alive. On the other hand, when it is germinating, it grows and creates cells. These cell-building activities need energy, and because they can't create food through photosynthesis, their only source of energy is cellular respiration, and when that goes up, carbon goes up.

Does the concentration of sugar affect the percent of mass change in potatoes?

# data[].attributes.subject
Does the concentration of sugar affect the percent of mass change in potatoes?

# data[].attributes.body
Hypothesis

Sugar concentration will affect mass.

Sugar concentration won't affect mass.

1. create 5 sugar solutions of different amounts

2. make 3 potatoes holes for each cup

3. Measure them before

4. leave them in the solutions for 1 night

5. measure them after.

# data[].attributes.body
Higher sugar concentration decreases the mass of potatoes left in the solution because of osmosis. The potatoes left in water with no sugar had a 10% increase in mass while the potatoes left in 0.8 sugar concentration decreased by 32.5%. This is because water follows the sugar because the water molecules get caught in the sugar molecule. This means whichever has more sugar is where the water will go.
