The lab we did on Thursday was really good preparation for launching rockets. It was basically the same lab on a bigger scale, with rockets instead of balls, and shooting vertically into the air instead of horizontally. However, unlike the lab on Thursday, our predictions were not NEARLY as close. When we switched from shooting vertically into the air to shooting at an angle, towards Mr. Blake, our calculations were pretty off... Instead of the 54 something meters we were hoping it would fly, it only got about 15. It seems to be the proof I was waiting for that Unit 4 will be much more difficult than Unit 3. Kinematics in 3D instead of 2D means more math, more equations, and more ways to screw up.
