I created these worksheets for my Marine Science classes. These worksheets are used to help students understand the scientific method.
The first sheet is a review for lab safety. Students will read through the passage and underline/highlight/ or circle the safety rules being broken.
The next two sheets, is a two page worksheet (1 page if printed 2-sided) that has 4 different experiment scenarios. The students are asked to identify the variables, controls and write hypotheses/conclusions specific to each problem.
The next two sheets, is also a two page worksheet (1 page if printed 2-sided) that has another 4 experiments and scenarios for the scientific method.
The last page is a 1 page worksheet having students practice designing experiments. Using their knowledge of the scientific method and using the practice from the other two worksheets, students analyze the scenarios and use critical thinking to determine the best methods and designs for each experiment. The last problem on the sheet asks them to design an experiment for the problem wanting to be tested.
These worksheets are ocean themed and up with recent times (not like those old worn out Simpsons worksheets, many students don't even know of the Simpson's!).
My high school Marine Science students enjoyed these worksheets and provided them with good practice on the Scientific Method!
When teaching with these practice sheets, I usually space them out over several different class periods. Then I go over them with the class. I even do the first problem in front of them, then we do the 2nd problem together, then the last 2 problems I have them do on their own.
