Fill out the following table to help you explain the Growing in the dark: Plants and light experiment

Aim - what are you trying to find out?	If plants need light to grow
Hypothesis - what do you think your results will be?	I think the plants do need light to grow
Independent Variable - what variable will you change?	The amount of light each plant has
Dependent Variable - what variable will you measure?	How much soil will be in the pot covering the seed
Controlled Variable - what variables will you keep the same?	The amount of water added to the plant

The students of Room 4 wanted to find out what colour of bird feeders birds preferred. FIll out the table below thinking of which variables you would make independent, dependent and controlled.

Aim - what are you trying to find out?	What colour do birds prefer on their bird feeders
Hypothesis - what do you think your results will be?	I think the birds will be use to the colour brown because it will feel like their eating out of the tree.
Independent Variable - what variable will you change?	Different colors on the bird feeders
Dependent Variable - what variable will you measure?	The amount of food added to the feeder
Controlled Variable - what variables will you keep the same?	The size of the feeders.
