By the end of these lessons, pupils will know that:
1) pressure exists on surfaces, in air and in liquids.
2) pressure is measured in Pascals (Pa)
3) on surfaces, pressure is calculated by dividing force by area.
4) pressure is smaller when a force is applied over a big area because the pressure is spread out over a big area.
5) pressure is bigger when a force is applied over a small area because the pressure is confined to a small area.
6) atmospheric pressure decreases with height,
7) liquid pressure increases with depth.
8) upthrust effects floating and sinking
9) hydraulics is an application of liquid pressure (qualitative and quantitative)
