Day 3 Activity 1 1/12/11 Scientific Method

Talk about process regarding car that does not start, what do you do?

What is the Scientific Method, explain the process and steps?

Relate the scientific process to the experiment that you performed on surfaces and liquids.

  1. 1. First off, when I get up that morning I would turn on the news and check the weather. I like watching the news, because I like to be prepared for all the types of weather conditions and the fact that I do live in Wisconsin the weather sometimes changes drastically. Next I would go out and start my car. If that does not work I would check all the possible solutions gas, oil, battery, ect. Next, if I had to absolutely drive that day I would call my dad. He knows a lot about cars, but I wouldn't call him unless it was an emergency. Hopefully, then my car would start and If it didn't I would e-mail the person and inform them that I won't be able to make it that day.

    2. The Scientific Method is a series of steps to help solve a problem. A way to remember the Scientific Method is by using PHEOC. Problem, Hypothesis, Experiment, Observation, and Conclusion. First Problem, address the problem or the question. Next Hypothesis, create an educated guess of how to solve the problem. Third, Experiment try different solutions to solve the problem. Following Experiment is Observation. Reflecting on your experiment and taking data about the Experiment. Lastly, Conclusion wrapping up the problem, including all the parts of the Scientific Method in the conclusion and reflecting on if you solved the problem.

    Problem: How to do last night's chem project?

    Hypothesis: Put 5 liquids on 2 different surfaces Styrofoam, and Tin foil and watch to see what the liquids do.

    Experiment: The liquids I used were dish soap, vegetable oil, nail polish remover, hydrogen peroxide, and water. We put them on two surfaces Styrofoam, and Tin foil.

    Observation: As I dropped the liquids on the two surfaces I began to notice how the liquids reacted to surfaces. Some of the liquids bubbled up on the Styrofoam, while others spread out like a lake. On the Tin foil some of the liquids spread out easily, while other stayed in the same spot. I created a chart on a scale of 1 (not spreadable) to 10 (very spreadable) to show the liquids that spread out the most.

    Conclusion: After the experiment, I noticed that water and the nail polish remover were the most spreadable liquids. Whereas, dish soap spread out the least.
