Hi 4F dearies,

Here are the explanations of common science terms/words that you may possibly encounter in your worksheets/tests.

variables = conditions
Change variables = conditions that can be changed.
Constant/ Fixed variables = conditions that are NOT changed at all.

e.g

Pot A: watered daily, adequate sunlight, airy place.
Pot B: watered daily, no sunlight (dark cupboard), airy place.

What is the change variable in this case? __________________________ (scroll down for answers)
And what are the fixed variables here? ____________________________(scroll down for answers)


Also, you can go to this web link to find out for yourself how changing the variables can cause the plant to grow differently. have fun!
