For this one, you will need some tape. (Scotch works best—especially the wider kind instead of the narrow.) You also need access to a faucet: kitchen, bathroom, garden hose, a water bottle with a hole in it.

Same expectation as as last time: I’m seeking concise, but meaningful answers based on careful observation, written in complete sentences. If English is your second language, or if it’s just not your specialty (It certainly wasn’t mine when I started out in a community college), I may start giving you pointers on grammatical or mechanical mistakes you are making.

What I will grade you on, however, is insightful answers based on patient observation and careful experimental work.

Since these activities are brief, you have no excuse if you refuse to repeat them a couple of times, trying to eliminate obvious goof-ups in your work—especially if nothing seems to be happening. In this one, for example, you are cutting strips of tape. If you make them way too long, they will cling to your sleeve, and that will ruin the result. I would expect you to comprehend this problem when it occurred and redo the experiment, correcting your error.

I can usually tell from your answer if you weren’t really trying. Play with the physics toys. I try to make these both easy and interesting. Enjoying them makes the work seem less like work.
