Document Summary

What are the 6 steps of the scientific method: observation, hypothesis, experiment, data, results, conclusion. First step of the observation, going from specific information to general information. It test the generalization using the hypothesis , 2-6 steps of the scientific method. Its multi-cellular, sexual reproduction, and has specialized orgnalles. Eukaryotic cells are with a large, complex collection of organelles, many of them are enclosed in their own membranes. Prokaryotic cells contain no membrane-bound organelles which are independent of the plasma membrane. It is like the brain of the cell. It"s the power house of the cell it gives it power. It lets certain things in and out the cell. Hydrogen bonds are not chemical bonds and they don"t form molecules. Cellulose and starch are found in plant cells. Glycogen is found in animals, it is the atp, which is the energy. The function of cellulose is forming the structure of a cell wall.

Scientific Method Exercise
Identify a situation in which you applied the scientific approach to solving a problem. Share your thinking! The problem you choose to write about can be very simple, such as: my flashlight won't work, or my car won't start, or I baked muffins and they were flat ( didn't rise properly) , or the toilet won't flush properly, or better yet, think of your own. These probably don't sound like "science" problems, but it is most likely that you would use the scientific method to solve them, without even realizing it. Avoid using people problems and child or pet behavior issues as your "problem." Follow these steps to create your first writing assignment:

1. Describe the situation and your observation,
2. Describe your hypothesis to explain the observation.
3. Describe your further observations or experiments to test the hypothesis. Be sure your hypothesis is one that can be tested. Consider what you might use for "controls".
4. Was the hypothesis correct? If not, can you find a better one? Or do you need a better experiment? If so, what would it be?

The assignment should be formatted as follows: Be sure to include the labels, so it is clear that you recognize and identify each step in the process.
Problem: (briefly describe your problem here)
Question: (This may be a "how" or "why" question that you will formulate a tentative answer to. Your tentative answer is your hypothesis.)
Hypothesis: (State the answer to your question above. This is your "best guess" regarding the answer to the question.)
Prediction: (This describes your experiment very briefly and states the outcome you expect that would support your hypothesis)
Experiment: (Describe how you tested your hypothesis)
Results: (Describe what happened, and whether the results supported or failed to support your hypothesis)

The scientific method

You are living in your very first apartment. After a month younotice that there is a large buildup of black mildew around thetub. Late at night you see an infomercial about a new cleaningproduct "Zap Gone" that claims to be able to fix this problem. youdecide to spend the $19.95 and order the product. when the productarrives you decide to test it by spraying half of the tub with the"Zap gone" cleaning product and the other half you spray withwater.

a. what is the initial observation?

b. state the question

c. state your null and alternative hypothesis

d. identify the control group

After 3 days of treatment there is no visible change on eitherside of the tub.

e. what should your conclusion be for this experiment?

f. what would be the next step in the scientific method?

Pick ONE of the examples below and describe the steps of the scientific method you would use to test the question or find the solution to the problem. In other words, please design a virtual experiment (using the steps of the scientific method) to test the hypothesis you make about one of the questions listed below.

Be sure to identify the steps (observation, hypothesis, prediction, experiment/test, controls, results, conclusions). In your responses to each other, help each other identify the parts of the process properly so that the results can be clearly interpreted
