Natural Science Review

Simple machines

Homework week 8 of june: 

1- Copy this information on your notebook: 

A lever makes it easier to move an object. It’s a rigid bar with a pivot point. This is the point where
the lever turns. The object we need to move exerts a force. This is called the load. The person using
the lever applies a force which is called the effort.

The wheel and axle was invented a long time ago. It makes moving about a lot easier. A pulley uses
a wheel and axle, and a rope. The axle passes through the centre of the wheel. There's a groove in
the outside of the wheel and a rope runs round it.

An inclined plane is a ramp used to liſt and to lower objects. It's the simplest of all the simple
machines because it only has one part and nothing moves to make it work.

2- Watch these videos to help you understand how levers, pulleys and inclined planes work. 

3- On friday12 of june at 11:00 we will play all at the same time to a Quizizz.

Zero gravity

What is zero gravity?

First, we need to know what is gravity.

Gravity is a non contact force that pulls us to the earth.

But, what happens when we leave the Earth?

In space, there is no gravity, which means that you can float!

Check how this astronaut has to eat his pudding in zero gravity.
