We can use this line to predict that the stem would have grown 8mm if we'd given it 25ml of water each day.

===Experiments for Scatter Graphs===
'''Air Resistance and Weight'''
: Time how long it takes a single Cupcake case to fall from the ground from 1.5 metres high.
: Repeat this for two, three, four and five cupcake cases stacked together.
: This changes the weight without changing the shape of the object.
: If the difference is too small for meaningful results try 2, 4, 6, 8 and 10 cases.
: Plot the results on a [[Scatter Graph]] (not a line graph or bar chart).
'''Air Resistance and Size'''
: Cut several different size parachutes from bin liners.
: Ensure that the surface area of each parachute increases by the same amount each time. This can support math skills calculating area of shapes.
: Use string to attach the parachutes to the same piece of plastacine each time.
: Plot the results on a [[Scatter Graph]] (not a line graph or bar chart).
