Actually testing a hypothesis means doing an experiment.
For any good experiment you need a plan, steps you’ll follow to make sure that each time you do it results will be consistent. And more importantly, so anyone else who wants to try it to see if it actually works can redo it as well.
So, make a plan, for this assignment is doesn’t need to be step by step, but we should be able to see the general idea of how you would test it.
A Control in an experiment is one Trial that you do to make sure that the results you get are actually BECAUSE of the thing you’re testing. Most experiments require one, but not all.
Hypothesis: Insulation slows down the melting of ice.
Test: Try melting ice in a container with insulation and time it.
Control: You also melt ice in a container without insulation to compare it to.
Pick THREE of the Following hypotheses to test, make a quick experiment (few sentences and include a control (something to compare results to) if you think one would be needed:
Beans grow faster in the dark than in the light.
A basketball falls faster than a ping pong ball.
Crushed ice melts faster than an ice cube.
A pot of salt water will boil at a lower temperature than just a pot of tap water.
There is no gravity in space.
Take a look and see if your prediction or hypothesis was correct!
