|Name of Activity
||LEGO Planet Rotation Structures
||LEGO, ROVs, rotation, model, structure, planets, solar system
||K, 1, 2, 3, 4, 5, 6
||1 Hour Total
||Students will assemble a rotating structure onto their pre-made LEGO ROVs.
||- To observe a model of planet rotation.
- To experiment with designing.
||Pre-organized LEGO kits
Pre-painted and labeled Styrofoam balls
Pre-made LEGO ROVs
Demonstration model with rotation structure
|Preparation and Set Up:
||- Arrange students in groups of two.
- Distribute materials.
- Bevel Gears
- Students will work with the same partners as they did in “ROVing Away.”
- Review the solar system with the class.
- Tell the students that each group will be given a styrofoam planet.
- Each group will use a motor and gears, mounted on top of their rove, that will make the planet either revolve around the RCX or rotate around its axis.
- The styrofoam planet will be attached by sticking it onto a LEGO axle. That axle will be attached to a series of gears attached to the motor, through gears so that it rotates.
- Let students experiment with gears to create a planet that either revolves on it’s axis or revolves around the RCX.
- Tell students that they can change the speed of the revolutions by changing the gear structures.
- Ask students: what gear arrangement is faster? Which is slower?
- Ask students what speed is most appropriate for their planet.
- Come together as a class and let each group demonstrate their machine and how they used gears to achieve their goal.
