• Modeling clay or papier-mâché (to create a volcano structure).
• Tray (to contain the mess).

Instructions:

1. Build the Volcano:
   • Use modeling clay or papier-mâché to form a volcano shape around the bottle. Leave the bottle neck exposed.
2. Prepare the Eruption Mixture:
   • Add 2 tablespoons of baking soda, a few drops of dish soap, and red food coloring to the bottle.
3. Erupt the Volcano:
   • Pour vinegar into the bottle and step back to watch the eruption.
4. Repeat and Explore:
   • Adjust the amounts of baking soda and vinegar to create different eruption sizes.

Guidelines for Learning:

• Explain the chemical reaction between baking soda (a base) and vinegar (an acid).
• Discuss real-life volcanoes and compare the experiment to actual volcanic activity.

5. Water Purification Experiment

Grade Level: 5th to 8th Grade
Age Range: 10–14 years
Objective: Teach kids about filtration and water purification methods.

Materials:

• Empty plastic bottle.
• Gravel.
• Sand.
• Charcoal (crushed).
• Coffee filter or cloth.
• Dirty water (can be made with soil and water).

Instructions:

1. Prepare the Filter:
   • Cut the bottom off the plastic bottle and turn it upside down.
   • Layer gravel, sand, and crushed charcoal inside the bottle, with a coffee filter or cloth at the bottom.
2. Filter the Water:
   • Pour dirty water through the top of the bottle.
   • Collect the filtered water in a clean container at the bottom.
3. Observe and Evaluate:
   • Compare the filtered water to the original dirty water.
4. Discuss Limitations:

Guidelines for Learning:

• Explore real-world water purification challenges.
• Discuss how these principles are used in water treatment plants.

6. Balloon-Powered Car
