The document outlines the steps to test a hypothesis through experimentation. It discusses observing samples, making a hypothesis about which powder will dissolve in water, conducting an experiment by putting the powders in water to see which dissolves, and drawing a conclusion about whether the original hypothesis was 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.

4. 5) Conclusion!
• Now we know if our hypothesis is correct or
not.
