Grade 3 Vehicle Challenge
Here are some photos from our grade 3 open ended challenge to design a WeDo vehicle. I reviewed 3 ways to connect motor to wheels before they started: gears, pulleys, or direct drives. Students used the base WeDo kit. However, I added additional long axles and tires/wheel from the WeDo Resource kit.
Students were trying first to make a stable chassis out of rubber bands.
This student and his partner quickly came up with a functional car design. He does many building projects at home with his father. He quickly built a chassis and drive train.
Notice the double belt
These students built the drive train (out of gears first) before building the chassis.
This was the final car from the student who is a gifted builder. They hid the engine under some LEGO plates and added a realistic steering wheel.
These students decided the more belts, the better. However, I believe they will be in opposition to each other and one will have to be removed.
Here’s another gear design. Usually, belts designs are easier than gear designs. However, 2 teams came up with good gear designs.
One girl did some design drawings, which is unusual without it being required. I suggested it but did not require it.
