Popcorn science experiments using the scientific method? Yes! Here’s what I mean.
Before we talk about popcorn science experiments, let’s take a look at the scientific method. There are some variations.
Here’s the first suggested method:
Here’s a variation:
1. Make an observation
2. Think of Interesting questions
3. formulate an hypothesis
4. Develop testable predictions
5. Gather data to test predictions
6. Develop general theories
1. Ask a question (How, what, when who, which, why, or where?)
2. Do background research (Use the library and the internet to research what is known)
3. Construct a hypothesis (If____then______will happen)
4. Test with an experiment (Do the experiment the same way at least 3 times)
5. Analyze Data (Collect your measurements and analyze them)
6. Draw conclusions (Did the results of your experiment support your hypothesis?)
1. Ask a question
2. Research your topic
3. State your hypothesis
4. Test your hypothesis
5. Analyze your date
6. Report your results
Communicate your results (In a written report or a display board)
The Variables—What can you change
Repeat the experiment at least 3 times to get accurate results
Biography and References
Remember, when using the scientific method, the results must be measurable.
Next, let’s look at some possible experiments using the scientific method and popcorn.
Here are some questions you can ask about popcorn.
Do white or yellow kernels pop better? You will need to make a decision about which pops better—that becomes your hypothesis.
Does popcorn popped in a microwave container pop better than popcorn popped in a hot-air popper? Your hypothesis could be: more popcorn kernels will pop when popped in a microwave popper than a hot air popper.
Does one brand of popcorn pop more kernels than another brand? Your hypothesis would be that one brand (say, Orville Redenbacher) pops more kernels than another brand (say, Jiffy Pop).
Does a commercial microwave bag of popcorn pop as well as popcorn popped in some other way (hot air popper, electric popper, stove top popper).
Does a commercial microwave bag of popcorn pop as well as popcorn popped in a microwaveable container?
Does the temperature of the kernels affect the amount that pops? Your hypothesis might be that popcorn stored in the refrigerator will pop more kernels that popcorn stored in the cabinet.
Does the amount of moisture in the kernels affect how many kernels pop?
If you color the kernels will the popped popcorn be that color?
Does popcorn from a commercial microwave popcorn bag pop as well as popcorn placed in a brown paper bag popped in the microwave?
All of these ideas can be researched by using the scientific method.
Results can be communicated in a written report.
Results can also be displayed in a graph format.
Tell us about your popcorn science experiment. What was your hypothesis? What were your procedures? What was your conclusion? How did you present your findings? You can upload pictures of your experiment.
