Frequently Asked Questions

A hypothesis is a guess or prediction that can be tested before an investigation. You can test the statement "Plants grow faster with fertiliser" by doing experiments.

Independent (what you change), dependent (what you measure), and controlled (what you keep the same). For example, when you test plant fertiliser, the amount you give is independent and the height of the growth is dependent.

The control group gives you a baseline to compare the effect of the independent variable. Without it, you can't be sure that your test results were caused by your test and not by something else.mindthegraph

Observation uses the senses to get information, while inference is drawing a conclusion from that information."The water is boiling" is an observation, while "The water will evaporate soon" is an inference.testbook

Keep everything else the same and only change one thing at a time. This isolates the effect of the tested factor for reliable results.
