Something very hands on, but easy prep and chemicals (etc).

Question: What is the control in my science experiment?

My science experiment was taking peoples blood pressure. Then having them listen to music to see if their blood pressure had changed.

Answer: Or you could use the same people on a different day, but have them not listen to music. If you’ve already done your experiment, you could say that the control is the people before they listened to music.

Try to keep everything the same except the music.

If the people sat still for 5 minutes while listening to the music, the control people should sit still 5 minutes while not listening to not music, then take their pressure again.

What they were doing before they listened to music could also have an affect on their blood pressure, for example, arguing with someone or watching TV or napping or eating, or even having their blood pressure taken. That’s why the people before they listened to music is sort of a good control (but maybe not the best).

But really you’re trying to separate what affect music has from everything else that goes on.

Question: What would be a cool experiment?

In my science class we’re doing a “matter magic show” so i need to think of a cool experiment to present to kids. Ive heard of this experiment where you light alcohol and sugar but im not sure if you know it please say so.

Answer: A nice little experiment I like to do with my kids is to make slime. All you need is water, white school glue, food coloring water, and Borax (found at any Wal-Mart). What you are basically doing is creating polymers. This experiment takes about 5-10 minutes, and creates a nice batch of slime that the kids can with and take home. I even had a good time playing with it. Check the website for exact specs.
