Forces

Today in theme we investigated the different forces on the Earth.

Aim: To find out why and how we stay on Earth

Equipment: Ourselves, bucket, and water.

Method:

1. Fill bucket 1/2 way with water.
2. Pick up bucket with dominant arm.
3. Swing bucket around body like doing freestyle as fast as you can.

What happened:
The water stayed in the bucket because we spun the bucket and the force kept the water at the bottom of the bucket.

How this affects us on Earth:

• The Earth is covered in water.
• The Earth is spinning on its axis.
• That is why we have gravity.

Gravity is the force that keeps us on the ground!!!!
