[45 Minutes]

Sir Isaac Newton is credited with discovering gravity or the force and attraction by which objects fall to the center of the earth. It was Sir Isaac Newton that explained why an apple falls from a tree down to the earth rather than up to the sky. Experiment with different objects to learn about gravitational forces.

You'll need:

• blocks • feather (purchased in craft store) • other household objects • timer

What to do:

  1. If possible, print out these directions. Read them through with your child before you begin.
  2. With your child, gather everything you'll need.
  3. Together, think about what "gravity" is. Gravity is a force that cannot be seen, but holds everything to the earth.
  4. Demonstrate gravity by letting go of different object and watching them fall to the floor.
  5. Let your child choose other objects from around the house to try dropping. Do objects fall more quickly or slowly, or do they all fall at the same speed?
  6. Use a timer to time how long it takes for an object to fall from a specific height to the floor.
  7. You and your child can record your estimate of how long each object will take to fall, then record the actual time for each object.

How to use:

  1. Do some research to find out more about gravity. Here are some questions to consider:
    Have you ever seen anything fall up?
    How was gravity first discovered?
    Why is the gravity different on earth than it is on the moon or on other planets?
  2. Then share what you've found out in your experiments and research with family, friends, or your child's classmates.

Let's Talk: Ideas to Explore Together.

  • Can you think of some things that seem to fall up instead of down?
  • What do you think would happen if there was no gravity on Earth?
