Session 5 Wheel and Axle
Google Classroom code https://classroom.google.com/c/MzUxMjUwMjI0MzEw?cjc=hmvrigh
Overarching questions are: What is a wheel and axle? Where are wheel and axle joints located in my body? How do I build a wheel and axle?
Station 1 Usefulness of the Simple Machine-The Wheel and Axle
Learning- At this station the campers will learn about the simple machine- the wheel and axle.
Activity- Identify the parts of a wheel and axle and identify where they are located in the human body.
Assessment- Students will be able to diagram ball and socket (wheel and axle) joints in the body.
Station 2 How to use levers in the human body
Learning - At this station the campers will perform exercises and identify the simple machines being used.
Activity- The campers will perform a throw at a target. They will aim at targets of varying distances.
Assessment- Students will write down how many targets they hit from different distances. Campers will rank their accuracy at hitting the targets of different distances.
Station 3 How to Build a Wheel and Axle using Vex
Learning - At this station the campers will learn how to build a wheel and axle using VEX.
Activity- The campers will build a wheel and axle. They will test turning the axle or turning the wheel and compare the force needed for each.
Assessment- Students will draw their wheel and axle. They will label their diagrams with fulcrum. Out Force and In Force.
Station 4 Reverse Engineer the Robot’s Wheels
Learning - At this station the campers will remove the wheels from the robot.
Activity- The campers will remove the wheels from the robot. They will take notes, draw pictures, etc. in the hopes that they will be able to rebuild the robot’s wheels and axles at a later date.
Assessment- Campers will disassemble the wheels from the robot. Some campers will be directed to put smaller wheels on the robot.
Station 5 Run multiple time trials with robots
Learning - At this station the campers will evaluate how changing the wheels affects the speed of the robot.
Activity- The campers will guide the robots as they race the course. For each race one person will be the starter, one will run the robot, one will time and one person will write down the time.
Assessment- Campers will write down their own time in terms of distance divided by time. Campers will rank the robots from fastest to slowest and use the data that they created to justify the rankings.
