Learning Objectives: To engage students in an open-ended engineering design challenge
that utilizes their motorized vehicles
The Challenge: In this activity students will be tasked with designing a vehicle that will
clear snow from a path

Learning Objectives: To introduce the students to pulleys and how they work
• What LEGO pieces make a pulley? (pulley wheel, pulley band)
• How do pulleys work?

The Challenge: Each student builds a 2-pulley wall (a beam with 2 pulley wheels, 2 axles, 2
...

Students will explore how changing gear ratios can increase the or decrease the propulsion they get from their propeller. This activity can also be done in conjunction with the Propulsion - prop size activity in this Underwater Robotics unit.

NOTE: The RCX should never be submerged in...

In this activity students explore how a propeller's size can influence the amount of propulsion they will get. They will build a simple set-up where they can record how many revolutions a certain propeller makes in a set time. This can be compared to the same set-up with different sized propellers. ...

This introductory activity gives students the challenge of building a LEGO boat (with limited pieces) that floats and holds the most weight afloat. The students will begin to see how buoyancy works and gain familiarity with putting LEGO bricks in water.

In this activity students will be asked to design a sturdy chair that keeps
Mr. Bear seated upright
