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?
|
If Plants need light to grow/ If they don’t!
|
Hypothesis - what do you think your results will be?
|
I think they will need light to grow, due to the possibilities of the plant dying without contact to the light outdoors and indoors.
|
Independent Variable - what variable will you change?
|
I would change the difference between how much light each plant receives,
|
Dependent Variable - what variable will you measure?
|
Height between each independent plant, before the experiment starts and when the experiment ends.
|
Controlled Variable - what variables will you keep the same?
|
I would keep the same amount of seeds and soil and water the same just to give each plant a good chance to grow,
|
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?
|
Room 4 and I am trying to find out which colour of bird feeders birds prefer,
|
Hypothesis - what do you think your results will be?
|
I think birds prefer brown bird feeders. Because more brown bird feeders are made then any other colour.
|
Independent Variable - what variable will you change?
|
I would change the colour and design of the bird feeder, making this experiment a close fair test.
|
Dependent Variable - what variable will you measure?
|
I would measure the height and length of the bird feeder in the beginning of the experiment and in the end.
|
Controlled Variable - what variables will you keep the same?
|
Type of food and the size this will give it a good opportunity to become a fair test.
