Entry one was one of my highest. I used work from a unit on radioactivity,
which I described as an extension or our study on atomic structure. The work
samples involved knowledge of terms, a couple exercises on half-life and a
debate on nuclear power.
For entry 2, I used a unit on work and simple machines. We do several
labs..pulleys, levers, etc. and work out word problems. I recently found an
activity in which the students build a lever to send a payload a specified
distance. It sounds like alot of fun and would have fit in well last year.
I would be happy to do anything I can to help you.
Are you involved in science fair in Brevard? I work with the regional fair
here and usually accompany students to the state fair. I'm also attending
the NSTA convention in Orlando in April
Keep in touch
