LET'S EXPERIMENT WITH FORCES

We are going to start a new topic in our Science lesson: FORCES.

Why the ball is moving in every case?

What are the people doing to move the ball?

And now, What is going to happen with the ball?

How is it going to move?

With all this previous information, can you say what a force is?

LET'S MAKE SOME EXPERIMENTS TO IDENTIFY DIFFERENT KIND OF FORCES.

1. Let's take an elastic band, and tie something like a key in one part. Hold the elastic band from the opposite part. Try to identify what happens on it and why it happens.

2. Take a plastic pen, and some small pieces of paper. Rub very quickly the pen with something made of wool. Then you will move the pen closer to the papers. Try to identify what happens on it and why it happens.

3. Let's take two magnets and try to put them together. Try to identify what happens on them and why it happens.

4. Let's play with a car. Launch the car along the floor of a classroom, First do it very soft and then do it stronger. What has happened? When has it stopped later?
