This science lab activity helps students understand the steps of the scientific method, as well as practice identifying independent and dependent variables. Furthermore, students learn the importance of a controlled experiment and using constants to test only one variable at a time.
During the lab, students conduct three experiments. First they conduct an uncontrolled experiment to see how the range in data is larger without constants. Then, they conduct the same experiment by controlling all of the variables. Finally, they change one variable (soap) and using the same constants, conduct the test again.
During each experiment, students share their data with their group and the class. I also have the class create a bar graph of their data. We further discuss outliers, as well as how to analyze data to draw conclusions.
I also have a powerpoint on the scientific method and a set of notes, vocabulary practice handouts, and crossword puzzle for sale that go along with this activity. If you are interested in these products, use the links below.
