Description

This is an engaging and enjoyable memory game on friction and air resistance. Pupils work in teams of three or four. Each team lays out their 42 cards face down in a square and take it in turn to turn over two cards. If the cards are a question and its correct answer, the pupil keeps the pair. If they are not a match they are turned face down and the next pupil gets a turn. This process continues until all cards are matched and the winner is the pupil with the most pairs.

If a team member thinks that the selectors pair is not a correct match, they can challenge.

Pupils are encouraged to check their books for the correct answer but the teacher also has a quick-check answer sheet. If the challenge is correct, the challenger keeps the pair.

Included in this Pack.

42 question and answer cards
Teacher’s answer sheet.
Instruction sheet

Preparation

Use double-sided printing to copy 1 set per group of 4 pupils.
Sheets could be laminated to enable year-on-year use.
Cut sheets into cards.

Prior Knowledge Required

Friction and air resistance act in the opposite direction to motion.
The rougher the surface the more friction it causes.
Friction produces heat.
Lubricants, such as oil, reduce friction.
Frictionis useful when it provides grip.
Frictionis not useful when it slows things down and wastes energy.
Frictionis a force and is measured in Newtons (N).
Air resistance is caused when the front of a moving object collides with air particles.
Air resistance slows an object down, produces heat and wastes energy.
Objects with a large surface area produce high air resistance.
Streamlined shapes have low air resistance.
A parachute has a large surface area and high air resistance.
When the weight of a falling object equals the air resistance the body then falls with steady speed.
