Real Air Around Us practice questions
Where is air found?
It is only found inside balloons
It is only found near the sea
It is only found high up in the sky
It is all around us, even though we cannot see it ✓
Air is all around us, everywhere on Earth, even though it is invisible and we usually cannot see it.
When you blow air into a balloon, it grows bigger and firmer. What does this show about air?
It fills up and takes up space inside the balloon ✓
It turns into water
It has no effect on the balloon
It disappears completely
As you blow into a balloon, air fills it up and takes up space, which is why the balloon grows bigger. This shows that air takes up space.
Which is slightly heavier on a very sensitive scale: an inflated balloon full of air, or the same empty, flat balloon?
An inflated balloon ✓
An empty, flat balloon
Air has weight, even though it is very light, so a balloon filled with air is slightly heavier than the same balloon when it is empty and flat.
What is wind?
A type of rain
Air that has disappeared
Water vapour only
Moving air ✓
Wind is simply air that is moving. We cannot see the air itself, but we can feel and see its effects, like leaves rustling.
