Part 1 - Step by Step
- InstructInstruct students to build a bridge using recycled materials to cross the 123 Tile.
- ModelModel how to get materials from the classroom station.
- Allow students to get a predetermined amount of materials per team.
- Display a timer at the front of the classroom for students to be aware of how much time they have to design their bridge before the end of Play Part 1.
- FacilitateFacilitate a discussion as groups build their bridge.
- Why did you select those materials?
- What will your bridge look like?
- Can the bridge hold the 123 Robot? Have students put their 123 Robot on the top of their bridge to test as needed.
- RemindRemind groups that their bridge design will not be correct the first time. Multiple iterations of the bridge is a part of the iterative process. The iterative processes means to try again and again. Failure is a part of success!
- AskAsk students to think about a time when they have failed but didn’t give up. Did you eventually succeed? Did you learn something? How did it feel?
Mid-Play Break & Group Discussion
As soon as every group finishes building their bridge, come together for a brief conversation.
- What differences and similarities do you see in each bridge?
- What differences do you like most? Did any surprise you?
Part 2 - Step by Step
- InstructInstruct students that the goal of this Lab is to create and run a project to code the 123 Robot to move an object over their bridge. Students will use VEXcode 123 to create a project, download the project to the 123 Robot and run the project to solve the problem.
- ModelModel how to create and download a project using VEXcode 123.
- Show students how to connect the 123 Robot to their device.
- Open VEXcode 123.
- Highlight the drivetrain commands students can use to code the 123 Robot to move across the bridge including Drive for (steps).
- Remind students that the When started block is always first and to connect the other blocks to the When started block.
- Create an example project and select download to show students how the project is transferred into the 123 Robots brain.
- FacilitateFacilitate a discussion as students are creating their project by asking the following:
- What distance will the Drive For block have to be for the 123 Robot to cross the bridge?
- Can you guess how many 123 Robot steps it will take to cross the bridge?
- Does it matter what order the blocks are in?
- Are there any blocks you are using more than once? Why?
- Did you test the project?
- RemindRemind students to use problem solving strategies as a team and encourage students to not give up when the team fails.
- AskAsk students where they have seen a robot solving a problem in real life? How does that relate to this Lab and this project?
