This week we have been comparing solids, liquids and gases.
We explored air using balloons!
We investigated whether an inflated balloon weighed more than a deflated balloon.
We learnt that air has a weight and is all around us. Therefore the inflated balloon weighed more!
Air resistance stops hang-gliders from falling quickly back down to earth with a bang!
Can you make a paper aeroplane dynamic enough to fly the longest time in the air? Try it at home and share your results with the rest of the class!
