ACTS is what the teacher will do and ASKS is how the teacher will facilitate.
Getting the Students Ready to Build
Levers are used to move and lift heavy objects by reducing the amount of force required to lift the object. Today, we will use VEX GO Kits to build a Lever and investigate how a lever makes work easier.
Facilitate the Build
- InstructInstruct students to join their team, and have them complete the Robotics Roles & Routines sheet. Use the Suggested Role Responsibilities slide in the Lab Image Slideshow as a guide for students to complete this sheet.
- DistributeDistribute build instructions to each team. Journalists should gather the materials.
- Builders can begin building. If there are multiple builders, they should alternate steps to complete the build.
- Journalists should assist with build instructions as needed.
- OfferOffer suggestions and note positive team building and problem solving strategies as teams build together.
- Ensure the Pink Pin is used for the pivot point. A regular pin will not spin as freely.
- Ensure students are attaching the Lever to the GO Tile. This will help prevent the build from falling over when forces on it are changed.
- Allow students to “play teacher” when they have a good understanding of a concept that they can teach another student.
- Remind students of the value of diversity—that different students within the group can bring ideas that should be considered. Diversity can help contribute to good problem solving techniques.
- If students are struggling to understand what a pivot point is, reference a seesaw or teeter-totter. Have students imagine if the Disks were on one side and the pins were on the other. How would that affect the seesaw?
