Small experiments suitable for third grade

Small experiments suitable for third grade are as follows:

1, compass: we all know that the compass is based on magnetic field research. So we will also use the magnetic field and magnetism when we make it. We can rub the needle we use on the top of the suction stone, thus making the needle stained with magnetism. After that we remove the magnet and the tip of the needle will move with the magnetic field. This little experiment is simple, the experimental apparatus is relatively single, can also be done at home.

2, car: we can explore the problem of gravity through the car. Before we do this little experiment, we also have to find a smaller toy car. After having the car we can place the cart on top of the slope. After that we can find out the truth that the slower the slope is, the more gravity the car receives and the slower it goes and vice versa.

3, carbon dioxide balloon: we can make carbon dioxide according to some safe chemicals. Finally by carbon dioxide we can blow up the balloon. This is also a small experiment in the third grade, of course, the required tools and materials are relatively simple. Just a few balloons, some white vinegar and a little baking soda. Of course, the materials are among the safer ones, but you still have to be careful about the balloons exploding.

4, obedient circle practice: take out a cardboard, put a small circle on it, she said to make the small circle obedient. Sure enough, she said "forward", the cardboard ring on the forward, "back", the small ring on the back, "circle", the small ring really turn up the circle.
