1. DIY Volcano Eruption Model

• Baking soda
• Vinegar
• Food coloring
• A plastic bottle
• Clay or paper mache for the volcano structure

1. Create a volcano shape using clay or paper mache around the plastic bottle.
2. Add baking soda into the bottle and food coloring to mimic lava.
3. Pour vinegar into the bottle and watch the eruption!

2. The Water Cycle in a Bag

• A resealable plastic bag
• A permanent marker
• Water
• Tape

1. Draw the sun, clouds, and ground on the plastic bag.
2. Fill the bag with water and seal it.
3. Tape the bag to a sunny window and observe how the water evaporates, condenses, and eventually "rains" back down.

3. Plant Growth Experiment

• Small pots
• Soil
• Seeds (e.g., beans)
• Water
• Different light conditions (sunlight and artificial light)

1. Plant seeds in small pots filled with soil.
2. Place some pots in sunlight and others in artificial light or darkness.
3. Observe the growth over a few weeks and note the differences between the plants grown in different conditions.

4. Magnetic Field Experiment

• A bar magnet
• Iron filings
• A piece of paper

1. Place a piece of paper over a magnet.
2. Sprinkle iron filings on the paper.
3. Gently tap the paper to see the filings align along the magnetic field lines, demonstrating the invisible forces at work.

5. Air Pressure Experiment

• A glass
• Water
• A piece of cardboard

1. Fill the glass with water.
2. Place the piece of cardboard on top of the glass and carefully turn it upside down.
3. Watch as the cardboard stays in place, and the water doesn't spill due to air pressure pushing from all sides of the glass.

6. Solar Oven

• A pizza box
• Aluminum foil
• Plastic wrap
• Black paper
• A thermometer (optional)

1. Line the inside of the pizza box with black paper to absorb heat.
2. Attach aluminum foil to the top flap of the box to reflect sunlight into the box.
3. Place the food item inside, cover with plastic wrap, and place the box in the sun.
4. Observe the food as it cooks using solar energy.

7. Density Tower

• Honey
• Dish soap
• Water
• Vegetable oil
• Rubbing alcohol
• Food coloring (optional)

1. Carefully pour each liquid into a clear container, starting with the densest liquid (honey) and ending with the least dense liquid (rubbing alcohol).
2. Observe how the liquids form distinct layers, with the denser liquids at the bottom.

8. Homemade Lava Lamp

• A clear bottle or jar
• Water
• Vegetable oil
• Food coloring
• Alka-Seltzer tablet

1. Fill a bottle with water, leaving some space at the top.
2. Add vegetable oil on top of the water.
3. Drop in a few drops of food coloring.
4. Drop in the Alka-Seltzer tablet and observe how bubbles rise and fall, mimicking a lava lamp.

9. Water Filtration System

• Plastic bottle
• Sand
• Gravel
• Activated charcoal
• Dirty water

1. Cut the bottom of a plastic bottle and turn it upside down.
2. Layer the materials in the bottle, starting with gravel, then sand, and finally activated charcoal.
3. Pour dirty water through the filter and collect the filtered water.

10. Static Electricity Experiment

• A balloon
• A wool cloth
• Paper scraps or small pieces of foil

1. Rub the balloon against the wool cloth for about 10 seconds to generate static electricity.
2. Hold the balloon near small pieces of paper or foil and watch as they are attracted to the balloon.
