Three groups tested their Lego Robots on the ramp in the classroom. I observed all groups running their robots up the ramp. I was pleased that we have more than one group running tests.
I observed the following:
- each group expressing their disappointment about how far up the ramp each robot was able to climb.
- each group speculating about how to fix the robot to make it climb higher.
- very few written observations being entered by the teams.
The Science comes from writing down what you are attempting. Describe the results. Describe a plan of action to redesign the robot. Run it again. Log the new observations, such as "It went 5 cnetimeters farther up the ramp. We change the tires by doubling up the tires on each side of the axle."
Tell your journal why you think an attempt or a redign was successful or not. This reveals your learning.
I would like a few comments concerning the ramp, drive trains, worm gears, traction, slipping and anything else that goes on when a robot is climbing!
