Science Investigation - Fair Testing

I learned that well you are doing a fair test you can only change one thing.

The first one room 4 did was  Growing in the dark: Plants and light.


Aim - what are you trying to find out?
If plants can grow without sunlight.
Hypothesis - what do you think your results will be?
I think the plant won’t grow in non sunlight.
Independent Variable - what variable will you change?
The seed of the plant.
Dependent Variable - what variable will you measure?
The water.
Controlled Variable - what variables will you keep the same?
The pot, bean seed and oil.

The second one was: What colour of bird feeders birds preferred.

Aim - what are you trying to find out?
