Since December, we work on engines. We found the definition of an engine: it is something (an object or an animal) which gives a movement.




Then we saw what the engine fuel: gasoline for the car, the wind to the sails, watch for electricity, food for the horse that grows a team ...

Today we worked on the engine of "small" cars.

We classified different engine cars.

We found 3 families Engine:
engines elastic: we must go back a spring. To move the car I can pull a string back, back wheels "back" ...

engines inertia: it is a weight that drives the motor. To move forward, it gives movement and weight rotates very quickly and causes the car.

Electric motors: these are the batteries or batteries that drive the engine.


Then we'll build our search engine to challenge the science of February!
