Week 9 science journal finn & jonty


Jumping frog

Some things i observed about the jumping frog is the fat ones don’t jump as high it think this is because the fat ones weigh a lot more than the small ones. Also if you make a big one you need to tie two rubber bands together otherwise it is too tight and either the rubber band would snap or the card would rip

Rocket sling shot
I noticed that you had to flick your wrist otherwise the rocket launcher thing would crash into the popsicle stick. I also noticed that it did not have much velocity.

Projectile launcher
We found out that 45° is the best angle to launch because it's not too high and not too low. If you do it over 45° it goes too high and drops down and if you do it under 45° it goes too low.
