5 Chris now has two stains on his shirt and two stains on his jeans. He needs to remove all four stains. He has two different stain removers, and now he must do an experiment to decide which stain remover works the best. The Experiment

6 The Experiment Chris used the Shout brand of stain remover on his t-shirt, which had a ketchup stain and a chocolate stain.

7 Chris used the Wal- Mart brand of stain remover on his jeans, which had a grass stain and a rust stain. The Experiment

8 AKer using both brands of stain remover, Chris compared his results. Did Chris design & carry out his experiment correctly? Why or why not? Redesign the experiment to help Chris determine the best spot remover. The Results

9 The Grading, or, How Do I Get an A? Criteria Advanced (4 points) Proficient (3 points) Basic (2 points) Below Basic (1 point) Correct Use of the Scien?fic Method All steps of the ScienDfic Method were clearly stated and used correctly to solve the problem. Students constructed a strategy for solving the problem with sound sciendfic reasoning. ScienDfic reasoning skills used to develop a somewhat useful strategy for solving the problem. Student demonstrated li<le effort. Student showed no use of sciendfic reasoning. Organiza?on & Validity Student stated a hypothesis with clearly-defined independent & dependent variables. Student s proposed experiment would produce valid results. Student stated a clear hypothesis. Student s proposed experiment would produce reasonable results. Student s proposed experiment would be somewhat useful. Student demonstrated li<le effort. Student s proposed experiment would not generate useful informadon. Repor?ng Results Student stated clear criteria for gauging the effecdveness of each stain remover. Student planned a clear method of displaying the results of the experiment. Student stated clear criteria for gauging the effecdveness of each stain remover. Student stated a vague idea of how to gauge effecdveness of each stain remover. Student demonstrated li<le effort or shows no criteria for gauging the effecdveness of each stain remover. Presenta?on Final product is neat, wellorganized, grammadcally correct, has few or no spelling errors, and clearly conveys the experimental design. Final product is neat, well-organized, and clearly conveys the experimental design. Final product is reasonably well-designed and more or less successfully conveys the experimental design. Student demonstrated li<le effort in design or accuracy of final product. Final Grade

10 The Grading, condnued Your score for each category will be added to calculate your final grade. You may use your notes and compare ideas with a partner or group member while you work. However, EACH STUDENT must turn in a copy of his or her own work. Your work MUST be your own. In other words, your paper cannot be idendcal to that of your neighbor.

11 The Grading, condnued On the back of the rubric sheet you just received, create a drawing, diagram, or short essay explaining how you would design this experiment. Be sure to answer the following quesdon: Was Chris s plan correct? Why or why not? Redesign Chris s experiment to help him determine the best spot remover. You have all of today s class period to complete this. Good luck!
