The document outlines the steps to test a hypothesis through an experiment. It involves observing samples, asking questions to gather information, making a hypothesis about which powder will dissolve in water, and then conducting an experiment by putting the yellow and white powders in water to see which one dissolves to determine if the hypothesis is correct or not.

1. It is time to test our hypothesis!
Let’s do the
experiment!

2. 4) Experiment
• In order to know if our hypothesis(guess) is
right or wrong, we make an experiment.

3. 2) Gather information: Sand does not dissolve in water but
salt dissolves in water.
1) Observe and ask: Which one is sand and which one is
salt?
3) Make a hypothesis: I think the white powder will dissolve
in water.
4) Do an experiment: Put the yellow and white powder in
water and see which one dissolves.
