Let's Create Direction: Read and analyze the simple experiment presented below. Reyn, Grade 7 student, wants to know why window grills and bridges are often coated with paints. She knew for a fact that these things are made of a hard metal known as steel. She then asked a question, what if these bridges and grills will not be coated with paints? What will happen to them? With her knowledge about scientific method, she decided to perform a simple experiment using steel wool and other materials that are found at home. Then, she prepared the following set-ups and placed them in their kitchen for 4 days.SET UP A Steel wool only SET UP B SET UP C Steel wool Steel wool Steel wool 2 tbsp vinegar 2 tbsp soy sauce SET UP D 2 tbsp water On the 4th day of his experiment, she noticed that rusts develop in each set-up. She noted the following observations: The steel wool in Set-up A developed small amount of rust, Set-up B on the other hand showed a steel wool covered heavily with rust, while Set-up C showed significant amount of rust on the steel wool and Set-up C also grew small amount of rust on the material.. It is now your time to help Reyn finish her experiment by filling out the Scientific Method Outline provided below. Write your answer on a separate answer sheet. Your output will be graded using the rubric on the next page Title: Problem: II. Hypotheses: Materials IV. V. Procedures Results D. Set-up (Drawing) E. Observation/Table F. Interpretation VI. Conclusion: (Answer why grills and bridges have to be coated with ppaint
