In Primary 4 we made hovercraft out of an old CD, a sports cap and a balloon.  We tested them on different surfaces.  I tested mine on water and it floated for a bit, but when the air was out it sank.  It worked the best on the lino because it was smooth and not too rough.

We made balloon racers from balloons, straws, bottles and junk.  The balloon was going to power the cars.  We had a race with Primary 7, to see whose went the furthest.  Aidan won for P7 and me and Shannyn won for P4.  We worked hard on our racer and had fun racing them.

In Science we made Rocket Mice.  We got a piece of paper and cut it into a cone shape.  We got a bottle put the mouse on the bottle, hit our hands against the bottle and made the mouse fly.  We tested different types of bottle to see which made the mouse fly highest.  We found out that the big fizzy juice bottle was the best.  We then got to decorate our mice too.
