Today we did an experiment to discover how the ‘mass‘ of different objects affect the force needed to move each object.
Materials:
- straw
- cotton ball
- rock
- 1 item from our pencil box
Instructions:
- Using the straw, see if you can make your objects move with just your breath.
- Record the observations you made, using pictures and words.
- Explain why you think some objects were easier to move than others.

What did we discover?
- the cotton ball moved very quickly because it was so light
- the rock would ‘wiggle’ but not move because it was so heavy
- pencils and crayons would move quickly because they were round and could roll
- erasers would not move because of ‘friction‘
Science is Fun!!
