I only did a year of genetics at University and that was 22 years ago!!!

I've been working in an inquiry primary curriculum since then...so...

My 7 year old son and I are working on proving (or disproving) the hypothesis that "everything we percieve is energy" vibrating at different frequencies.

Tonight, I caught him trying to see if he could make a magnetic chamber to charge (and test!) his crystal collection!!

I think it's time I got some expert input?!!
All insights welcome!

does my dog love me? I certainly love him.
the comedian ralphie may does a bit about sigfried and roy getting ate by a tiger and it just raised a question with me. can a tiger like you or love you? if you hand feed a tiger a steak every day for like 2 years and then stop feeding him will he eat you just as fast as a tiger who was equally hungry but had never seen you before and would a tiger that you had been taunting for two years eat you faster or slower than any of the two before mentioned if he was equally hungry?

After the astronauts land, what do they do to get re-accustomed to gravity, and what medical check-ups do they go through? It must be easier for the astronauts who are only up in space for a couple weeks, than for someone who was at the space station, and up in space for 5 months.

With this landing (STS 120 -- 11/07/07), two astronauts did not walk around the shuttle. One of them was only up for 2 weeks, and the other was up in space for 5 months. Do they have to do something special for the people who were in anti-gravity for 5 months?
