Fair Testing

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?	We’re trying to find out if plants need light to grow ?
Hypothesis - what do you think your results will be?	I think the result would be that the plant without light would stay the same.
Independent Variable - what variable will you change?	I would change the amount of planet spray.
Dependent Variable - what variable will you measure?	I would change the measurement of soil.
Controlled Variable - what variables will you keep the same?	The amount of plant seed.

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

Aim - what are you trying to find out?	What colour of bird feeders do birds preferred
Hypothesis - what do you think your results will be?	I think the birds would pick the red bird feeder, because it’s not too bright colour or too dark.
Independent Variable - what variable will you change?	I would put different types of colours, like bright and dark, cold colours and hot as well.
Dependent Variable - what variable will you measure?	The amount of seeds in all the bird feeders.
Controlled Variable - what variables will you keep the same?	I would put all the bird feeders in the same place.
