Fun Science Projects for Cub Scouts

Volcano in a Bottle

  • This project teaches Cub Scouts about chemical reactions. You will need a clear, slender-neck bottle, baking soda, vinegar, dishwashing liquid, food coloring and glitter. Add baking soda and glitter to the bottle until it covers the bottom. Place the bottle in a pan or bowl (for spillage). Separately mix 1/4 cup vinegar and two drops each of food coloring and dishwashing liquid. Use the funnel to add the vinegar mixture to the baking soda. Stand back and watch the eruption.

Mini Rocket

  • This project teaches Cub Scouts about chemical reactions and pressure, and should be performed outside, or in a well-ventilated area. You will need baking soda, vinegar and an empty film canister with a lid. Remove the lid and tightly pack it with baking soda. Add 2 teaspoons of vinegar to the canister. Gently put the lid on the canister until it snaps, turn it upside down and put the canister in the ground. Step back and watch the mini rocket blast off.

Cyclone in a Bottle


  • This science project teaches Cub Scouts about weather. You will need water, food coloring, glitter, two empty 2-liter bottles with labels removed and masking tape. Fill one bottle halfway with water. Add two to three drops of food coloring and glitter. Place the other bottle upside-down over the first bottle, and tape them securely together. Hold the bottom bottle firmly and the top bottle steady, and swirl. Flip the bottles over and watch the colorful cyclone.
