Now take a look around you at all the living things you see. Ever wonder why a bee is attracted to a particular flower, or what would happen to an apple tree if there were no bees? If you were a scientist you could do an experiment to answer your question.

For this assignment, choose two organisms that interact with each other, such as bees and flowers, or consider the effect of any environmental factor on an organism, such as light, sound, air quality, food preference, or nutrient quantity or quality.

Now form a simple hypothesis about this interaction. Include the observation that led you to a hypothesis . Use the scientific method and your imagination to design an experiment that you might do to test this hypothesis. Be sure to include controls, and describe the variables that would remain constant and the one that you want to test. (Remember, you can only test one variable at a time.) Describe the type of data you would collect, and how you would evaluate it. What are your expected results (predictions)? State what your conclusion would be depending on those results. Would these results lead you to accept or reject your hypothesis?

Your format should then look like this:

Introduction: Describe your observation. Include any background information you may have found.

Hypothesis: Write a statement that describes your explanation for the observation.

Methods: Describe the experiment, variables to be held constant, variable to be tested, and controls.

Predictions: What do you predict as outcomes (results) of this experiment?

Conclusions: Do you accept or reject or accept hypothesis? Explain why.

Remember, you don't have to actually do the experiment, just write what you would do to test your idea.

The scientific method consists of four steps.
1) Observation
2) Formulation of a hypothesis (an idea that explains the why or how of your observation)
3) Use your hypothesis to making a prediction
4) Test your predictions (if your theory truly explains your observations you should be able to predict the outcome of future events)

For more information on the scientific method see http://biology.clc.uc.edu/courses/bio104/sci_meth.htm or http://teacher.pas.rochester.edu/phy_labs/AppendixE/AppendixE.html You can find more information by typing 'scientific method' into any search engine such as yahoo or google.

Let's start by picking our subject and observation. You are given the example of bees and flowers. There are many possibilities here such as the predator/prey relationship between wolves and snow hares, trees and lichen, the shape of seeds and wind etc. Basically any interaction you observe in nature between two ...

Scientific Method - setting up experiments with conditions: short answer

(1)I need to create two experiments on the effects of acid rain using the scientific method. With the hypothesis, experiment and conclusion as the format of the experiment.

(2)Using the following statement and the scientific method, I have to design a scenario in the format of question- experiment- results-conclusion to test assumptions of death by loneliness.
"I have a lit candle that I put under sealed glass in a dark room by itself. I come back in a few minutes and the flame has died. I immediately assume that the flame died because it was all alone (it was alive and died of loneliness).
