Galileo for Kids

Galileo is famous for many things. He was a great scientist, inventor, and astronomer just to name a few. After your students have some understanding of who Galileo is, there are a variety of activities and games that can be used in an elementary classroom to ignite a spark in your own little budding scientists! Here are a few activities suggestions that you can incorporate into your lesson plans.

Painting With Pendulums

In this activity, students get to create and observe how a pendulum works. All the while, they are creating a unique artistic design.


  • Paint (washable) - add water to thin out more if needed
  • Foam or paper cups
  • Scissors
  • String
  • Tape
  • 2 chairs for each pendulum
  • Brooms or dowel rods
  • Large drawing paper or a roll of brown craft paper
  • Plastic tablecloths or other drop cloths


  • Divide students into small groups.
  • Place the tablecloths under each work space.
  • Prepare the cup: Poke a hole at the bottom (for the paint to come out). Poke one hole on each side of the cup. Attach and tie the string through holes at the sides of the cup.
  • Place the string at the middle of the broom or rod. Balance the broom or rod between the two chairs.
  • Test your pendulum by putting water in the cup to make sure it works before you add paint.
  • Place tape at the bottom of the cup to cover the hole until you add the paint.
  • Take the tape off and give your cup a swing!
  • Have students observe, discuss, and take notes on how the pendulum moves.
  • Discuss the pendulums and share creations as a class.
