Steps in order Problem/purpose Hypothesis Materials Procedure Data & Results Conclusion

This is why you are doing the experiment. Problem/Purpose This is why you are doing the experiment.  

Hypothesis (If….then…) A hypothesis is an educated guess stated in terms of cause and effect. Example: If the water temperature is increased, then the amount of sugar that can be dissolved in it will increase.

The things that you need for the experiment. Materials The things that you need for the experiment.

Procedure These are the steps you complete during the experiment.

Data and Results After you have followed the steps of the experiment, record the data and find out your results. Record your data on a chart or graph. Is there anything unusual about your results?

Scenario 1 Ashley and Jake wanted to do an experiment with magnets. They listed the things they needed to do the experiment: magnets, toy cars, and rubber bands. What part of the scientific method is this called? Materials

Scenario 2 Conner and Karen were testing to see which ball, a basketball or a tennis ball, would bounce higher. Before they did the experiment, each of them made an educated guess about what they thought would happen before the experiment. What part of the scientific method is this called? Hypothesis

Scenario 3 Ms. Waters and Ms. Brown measured how high they could jump by wearing different kinds of shoes. From their results, they found out that shoes with rubber soles are better for jumping than shoes with plastic soles. What part of the scientific method is this called? Conclusion

Scenario 4 Jacob and Clark wanted to test if sugar or salt dissolved faster in hot water. In order to do this, they followed certain steps to complete the experiment. What part of the scientific method is this called? Procedure
