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.

Natural Science: Levers

Good morning, kids: 

As you know, we are studying simple machines. Levers are a good example of those tools that make work easier. 

Have a look at the next video that explains how levers are made and how they work. 

See you later ;)
