Materials:

Balloon

Wool cloth or your own hair

Small paper scraps or cereal pieces

Steps:

1. Blow up the balloon and tie it. (2 mins)

2. Rub the balloon vigorously on your hair or a wool cloth. (2–3 mins)

3. Hold the balloon near paper bits or a wall. (2 mins)

4. Observe how the balloon attracts them or sticks to the wall. (5 mins)

5. Try rubbing more or less and observe changes.

Optional Extensions:

Test with plastic, wool, or silk fabric—compare results.

2. Magnet Maze

Age Group: 6+
Concept: Magnetism
Duration: 15–20 minutes

Materials:

Paper

Marker

Magnet

Paperclip

Tape

Steps:

1. Draw a simple maze on a sheet of paper. (5 mins)

2. Tape a paperclip on top of the paper. (2 mins)

3. Place the magnet underneath and try to move the clip through the maze. (5–10 mins)

4. Try using different magnets to compare strength.

Optional Extensions:

Materials:

Plastic bottle (cut in half)

2 balloons

Straw

Tape

Rubber band

Scissors

Balloon or plastic sheet for bottom

Steps:

1. Cut a plastic bottle in half. Keep the top part. (3 mins)

2. Insert one balloon into the neck, pull the lip over the bottle mouth. Tape to secure. (5 mins)

3. Stretch a balloon or plastic sheet across the open bottom like a drum—this acts as the diaphragm. (5 mins)

Go to kindergarten and do science experiments

1. Dancing Raisins

Concept: Buoyancy and gas bubbles
Materials:

Clear soda (like Sprite or 7-Up)

A clear glass

A few raisins

Instructions:

1. Pour the soda into the glass.

2. Drop in a few raisins.

3. Watch them sink and then "dance" back up as bubbles stick to them.

Why it works: Bubbles of carbon dioxide lift the raisins; when they pop, the raisins sink again.

2. Rainbow Walking Water

Concept: Capillary action and color mixing
Materials:

6 clear cups

Paper towels

Red, yellow, and blue food coloring

Water

Instructions:

1. Fill every other cup with water and add food coloring (Red - empty - Yellow - empty - Blue - empty).

2. Roll paper towels into strips and place them to connect the cups.

3. Watch the water "walk" to the empty cups and mix colors.

Why it works: Water travels up the towel through capillary action and mixes colors in the empty cups.

3. Magic Milk

Concept: Surface tension
Materials:

A shallow dish

Milk

Food coloring

Dish soap

Cotton swab

Instructions:

1. Pour milk into the dish.

2. Add drops of food coloring.

3. Dip a cotton swab in dish soap and touch the center of the milk.

Why it works: Soap breaks surface tension, causing the colors to swirl and move.

4. Volcano Eruption

Concept: Acid-base reaction
Materials:

Baking soda

Vinegar

Food coloring

Small container (or plastic volcano model)

Instructions:

1. Put baking soda in the container.

2. Add food coloring.

3. Pour in vinegar and watch it fizz and erupt.

Why it works: Vinegar (acid) reacts with baking soda (base) to produce carbon dioxide gas.

5. Sink or Float

Concept: Density
Materials:

A large bowl of water

Assorted small objects (coin, cork, plastic spoon, rubber ball, etc.)

Instructions:

1. Let kids guess which objects will sink or float.

2. Test each one and observe.

Why it works: Objects sink or float based on their density compared to water.

Would you like a printable worksheet or coloring pages to go with any of these?

we should introduce them to cells.

we can tell them the cells are everywhere and including themselves.

We can take a leaf and put it under a microscope and let them look in it.

A cell is a tiny building block that makes up all living things. It's like a LEGO piece for your body!

Make a example of animal cells and plant cells

Popsicle sticks

Rubber bands

Soft balls ( Crumpled Paper )

Tape ( we will help them use it )

Plastic spoon

Materials Needed:

A clear glass or cup

Raisins (about 5–10)

A bottle/can of clear carbonated drink (e.g., Sprite, 7-Up, or soda water)

Procedure:

1. Fill the glass
Pour the carbonated drink into the clear glass until it’s about 3/4 full.

2. Drop the raisins
Gently place 5 to 10 raisins into the drink.

3. Observe what happens
Watch the raisins for a few minutes. You'll notice:

At first, they sink.

Then, bubbles attach to the surface of the raisins.

As bubbles build up, the raisins rise to the surface.

When the bubbles pop, the raisins sink again.

This cycle repeats — they appear to “dance” up and down!

# data[].attributes.body
The bubbles of carbon dioxide gas stick to the rough surface of the raisins. When enough bubbles collect, they make the raisins float. When the bubbles pop, the raisins sink. This creates a dancing effect!

Light and Shadow (Shadow puppets):

1. We would have an activity where we would explain and teach the concept of light and shadow to the children

2. We would ask the children to interact with the set up with the torch, that we have created, and use objects that are transparent, translucent and opaque to cast the shadows onto a wall.

3. They can also move the objects on the set up so that they can observe the size of the shadows change on the wall.

4. We will give the children some materials for them to create their own prop for the experiment.

5. We will then explain why a shadow can be casted and be able to have different shapes.

Clothespin catapult:

It’s a simple device that uses potential energy from the clothespin when pressed down and when released its converts into kinetic energy that releases the crumpled paper inside it.

Materials needed:

Double-sided tape

Crumpled paper

Popsicle sticks

Clothespins ( wooden )

Bottle caps

Rubber bands

Coloured markers

How we will we explain it to little kids :

When you press down on the clothespin , the clothespin gets collects a lot of energy. Energy is basically what people or things use to move. Energy that is collected and not used to move is called potential energy. When you let go of the clothespin, the potential energy, which as we can recall, is energy that is not used to move , will be converted to kinetic energy which will allow the crumpled paper to fly! Kinetic energy is energy that is used to move or do anything. So, after all this, what happened is just that the clothespin had potential energy when we pressed down on it, then when we let go of the clothespin, the potential energy gets converted into kinetic energy, which will let the paper ball fly.

# data[].attributes.body
We can use legos to represent the plant cell and animal cell and tell them that cells are everywhere including themselves. We can also tell them that cells are microscopic and only can be seen under a microscope.

We also can have a lego building activity that requires them get into groups of 4 and built a plant cell , we will guide them from step by step so that they will not get lost building the wrong thing. We would also let the children use the microscope but we will not let them hold it or touch it so that there will not have any broken things.

The materials needed:

lego bricks ( to build the animal cell and plant cell )

Microscope( if allowed )

Leafs ( to see under the microscope )

1. Magic Walking Rainbow
Place six cups in a circle. Fill three with red, yellow, and blue water. Leave the others empty. Connect them with paper towels. The coloured water travels and mixes into new colours.

2. The Jumping Coin
Put a coin on top of a glass bottle. Hold the bottle with your warm hands. After a while, the coin jumps or makes a clicking sound.

3. Dancing Paperclip
Hang a paperclip on a string. Move a magnet close to it without touching. The clip floats and moves.
Science concept: magnetic force – magnets can pull objects from a distance.

4. Disappearing Water
Use three cups, one with a sponge hidden inside. Pour water into that cup, then turn all the cups over. The water has “disappeared.”
Science concept: absorption – the sponge soaks up the water and hides it.

5. Levitating Ping Pong Ball
Blow through a straw or use a cool hairdryer. Hold a ping pong ball in the air stream. It floats in place.
Science concept: air pressure – fast-moving air lifts and holds the ball in the air.

Logistics list:

6 clear plastic or glass cups

3 opaque cups

Red, yellow, and blue food colouring

Water (enough for all tricks)

Paper towels (at least 6 sheets)

1 glass bottle (narrow mouth)

1 metal coin (like a 20 or 50 cent coin)

1 clean sponge (small, fits inside a cup)

1 strong magnet

1 or more paperclips

String (about 30 cm)

Tape or blu-tack

1 ping pong ball

1 wide straw or hairdryer (cool air only)

Clean cloth or tissue (for drying or cleanup)

Table for setup
