Question • Start with a question. What do you want to learn about? Asking questions is the first step towards designing experiments. • Example: You observe that it is cloudy today and make the inference that it might rain, so you ask the question “will it rain when the clouds are grey?”
Hypothesis • An educated guess that you can test. Always write your hypothesis as an “If-Then” statement. • Example: If it is a cloudy day, then it will rain 60% of the time.
Experiment/Data • Gathering information, doing an experiment, measuring, recording your observations while it is happening. • Example: You go outside every day that the clouds are grey and you check to see if it rains.
Results/Calculations • This is where you take all your data from the experiment and organize it. If you need to do some math you do it here as well. • Example: You gathered 20 days of data on grey cloudy days during your experiment. Now, you find the percent of days it rained. If it rained 14 days out of 20, then it rained 70% of the days.
Conclusion • This is where you write what you learned. You check your hypothesis to see how close you were. You write down things you would do different next time. You write down other questions that you have now that you have done the experiment. • Example: I thought it would rain on grey cloudy days 60% of the time. It ended up being 70% which is more often than I thought. One question I have now is “how much it will rain on cloudy days?” Sometimes it rained a lot and sometimes it rained a little bit, but the experiment I did only measured if it rained at all.
