Elliot from Wilson's School sent the
The radius-number of pumps graph of the balloon links to the 1st
graph, as the radius would gradually increase by less as the volume
The temperature-time graph for the tea links to the 2nd graph, as
the temperature would decrease less as it cools down.
The odometer reading-time graph links to the 3rd graph, as the car
is moving at a constant speed, so the distance would also increase
The height-distance graph for the bicycle valve links with the 4th
graph, as the valve's height would increase and decrease as the
wheel rotates around.
The distance fallen-time graph links to graph 5, as you would
accelerate, meaning your distance fallen would gradually increase
The volume-time graph for the water links to graph 6, as the water
is sucked out at a constant rate, so the volume would decrease at a
The height-time graph for the tennis ball would be graph 7, as the
height would increase when you throw it, then gradually stop
increasing and decrease again as it falls.
The metres-inches graph links to graph 8, as the number of inches
would be much greater than the number of metres, creating a very
shallow straight line.
Niharika came up with some processes of her own that each
graph could represent.
Linden explained the shape of each graph and found
the correct equations.
