Natural Science: simple machines

Hello, kids!

I know Unit 6 (machines) is a bit difficult. Have a look at the next videos about some of the simple machines we have already studied. They may be useful. 

Ramps

Levers

Pulley

See you later ;)

Natural Science: simple machines

Hi, kids.

In a few days you will take a new Natural Science test. One of the things we are studying is simple machines. Have a look at the next video to go over the six types we have studied and some of their uses (there is some information you won't understand, but do not worry).

See you tomorrow.
