testing hypothesis

On Friday, for science, we made 2 airplanes out of straw, cardboard box, tape and clay (per Apologia Zoology book). One of the airplanes' wing is long and narrow while the other is short and wide. We try to guess which would fly further. Initially, J guessed the short and wide but after she saw the planes they both guessed the long and narrow.

We were suppose to try numerous times and calculate an average per the book for the 2 airplanes but we didn't (though this would be a good exercise for J). We threw enough times to know the long and narrow can fly farther all other circumstances equal.

We tried many different variations, both hands (taking into account they are both right handed), throwing purposely harder, throwing into the wind, against the wind, holding it differently etc.


Later, it was more fun and games with one of us being target or seeing who can throw it farther.

Getting ready to aim

Yeah!Got him.

I hope I can do this.

A rare side view shot.

I also want to put in here since it has been raining, the fire hydrant in the cul- de-sac behind us had to drain the water out as it is in a dead end. Initially, we all wondered why the man is letting the water pour out of the fire hydrant on a raining day. The kids had a great time playing with all the water gushing out the hydrant and jumped in rain puddles and experienced pushing against the wind. The workman was kind enough to let the hydrant drain little longer than usual as the kids was clearly enjoying themselves.
