It's a new term, and that means a new Science topic!
This term our topic is FORCE and MOTION. Today we were given a challenge.
How to make Jade's boot move without touching the boot.
Ben tried
blowing. It moved the top of her boot, but the boot didn't move along the table.
Maggie
lifted the table, but the boot didn't slide.
Juan used Maggie's idea. He
lifted the table, then
jiggled the table. The boot moved along!
Caleb used a piece of string and
pulled the boot so it moved down the table.
All of the words in bold are different types of FORCES. We came up with the idea that forces are movements (pushes or pulls) that move objects.
We learnt that
GRAVITY is a force. Gravity is an invisible force that
PULLS objects down.
In groups, we brainstormed as many different forces that we could think of.
Lifting, pulling, pushing, hitting, kicking, rolling, twisting, turning, dragging, bouncing, shaking, squeezing were just some of the clever ideas we came up with.
(Someone even suggested telepathy!) Hmmm. Not sure about
that one!
We are going to have lots of fun experimenting with simple machines and learning about force and it's affect on movement.
