Science Buddies: "Ask an Expert"

My daughter has decided to do a Science Fair Project on Are you Left-Brained or Right-Brained? The only problem is coming up with a purpose to an experiment. We thought about "What percentage of people are left-brained & what precentage of people are right-brained?" Does that sound good or does anyone have a better suggestion?


Thanks for your help.

Thanks for your help.

That sounds like a great idea. Often scientists express things as a hypothesis - or a guess about what the expect to see. Maybe you can do this, too. An example would be "We expect that the percentage of right-brain people is X percentage" or "We expect that there are more right-brain people than left-brain people." The good thing about starting your experiment this way is that you can get insights into how you think "real life" works, which can also help you determine how you need to design the experiment.

After determining a hypothesis, next you figure out the methodology needed to test your hypothesis, do the test (or experiment), and, finally, see if your results support your original ideas.

Hope this helps.

Your purpose/question looks and sounds very nice. Now that you have your purpose stated, take a look at what kmanies has to say about comping up with a hypothesis!

You're off to a great start!
