Have students practice the steps of a STEM experiment with a small activity. I love to use a "problem" that needs to be solved in a minute! (ex. stacking cups, building a tower) This worksheet is a great outline that shows the process behind conducting your own experiment.
1) State your problem
2) List Materials
3) Design and describe plan
4) Conduct experiment
5) Describe Results
6) Reflect/ How can you improve?
