Lesson plan
Recap and recall
Hand out whiteboards and pens (one each) and arrange the class into pairs. Assign one of each pair the role of Sir Isaac Newton or Galileo Galilei. Instruct them to write down their contributions to the theory of gravity as discussed in the Pupil video: Gravity (see Lesson 1: Gravity). Ask them to debate who contributed…

Adaptive teaching
Pupils needing extra support
Could drop three different-sized balloons without adding string and the Resource: Parachuter cutouts; should be provided with the Resource: Investigating air resistance variables to help them identify variables to test, measure and keep the same and write their method.
Pupils working at greater depth
Should extend the experiment by adding different weights (made from modelling dough) attached to the Resource: Parachuter cutouts to see how it affects the fall of the largest parachute (the more weight added, the quicker the parachute should fall); could choose an extension activity relating to air resistance from the Resource: Stretch and challenge: Unbalanced forces.

Knowledge outcomes
Knowledge
- I can define air resistance as a contact force that opposes motion to slow or stop objects moving through air.
- I can describe the relationship between surface area and air resistance; the larger the surface area, the greater the air resistance and the greater the slowing effect.
