L.T.: I can write a 4 pt. conclusion on my Fan vs. Mousetrap Car Lab and write a hypothesis and procedure for our new Q.
DO NOW: How many points does this conclusion get and why?
The fan got 0.21 and the MT got The fan was faster.
…………………
Reflection:
Was I able to
accurately report out my results in a full 4 pt conclusion?
Did I make a prediction about my car’s motion in a 3 part hypothesis?
Do I have all 3 variables, set-up description, and logical steps in my procedure?
