ACTS is what the teacher will do and ASKS is how the teacher will facilitate.

ACTS ASKS
  1. Discuss students' answers regarding their experiences using passwords.
  2. Continue the discussion about the need for passwords, listing ideas on the board.
  3. Show students the robot, drawing attention to the LED Bumper. Guide students to suggest that they could use it to flash a coded pattern to represent a password.
  4. Show students Field setup where they will test their projects.  Show them VEXcode GO open on a tablet or computer, and the Super Code Base.
  1. Have you ever had to create and enter a password in order to use a website or app?
  2. Why do you think passwords are necessary?
  3. Now that the robots are able to successfully pick up and deliver cooling cells, we need to establish some security for the cooling cell lab, so only authorized cooling couriers can access them. How do you think we could use our Super Code Base robots to display a password?
  4. We are going to use the LED Bumper on our Super Code Base robots to create passwords for each of our robots. How do you think we can we code the robot to create and manage safe and secure passwords?

Getting the Students Ready to Build

Let's see how we can create a secure password with the LED Bumper on our Super Code Base! (If students do not have a pre-built Super Code Base from the previous Lab, allow an extra 15-20 minutes for students to build it prior to the Lab activities.)

Facilitate the Build

  1. InstructInstruct students to join their group, and have them complete the Robotics Roles & Routines sheet. Use the Suggested Role Responsibilities slide in the Lab 2 Image Slideshow as a guide for students to complete this sheet.
  2. DistributeDistribute one pre-built Super Code Base, a VEX GO Kit, and a tablet or computer with VEXcode GO to each group.

  3. FacilitateFacilitate students opening the Starter Password VEXcode GO project in VEXcode GO.
    • Note: This project (also linked in the Materials List on the Summary page of the Lab) can be downloaded to students' devices prior to beginning the Lab. The project will directly download to your device when the link is selected.

    • If desired, build the project together with students. Begin by building the "1st Number" section of the project, then demonstrate how to right-click to duplicate blocks and change their parameters for the remaining sections.
      • Begin by building the "1st Number" section of the project, as shown here.

      • Demonstrate how to right-click on the Repeat block to duplicate blocks and change their parameters to complete building the project.

    • Be sure to circulate through the room to monitor students as they are working to ensure each group has built the project correctly before moving on to the Play section of the Lab.
    • When students have completed building their project, have them name their project Starter Password and save it to their device.
  4. OfferOffer positive reinforcement for students who are collaboratively engaging in the process of building the project. Remind students that they can take turns so that all students can have an opportunity to use VEXcode GO.

Facilitation Strategies

  • To ensure all groups are building the project along with you correctly, circulate through the room and do a quick check of students' project after they add each section.
  • Think about how your students will access VEXcode GO. Ensure that the computers or tablets that students will use have access to VEXcode GO. For more information about setting up VEXcode GO, see this VEX Library article.
  • The Starter Password project can be downloaded to student devices prior to beginning the Lab. View these device specific articles to learn more about opening an existing project in VEXcode GO: Chrome BrowseriPadAndroidChromebook
  • In the Starter Password project, the number of flashes of the LED Bumper corresponds to the digit in the password. For example, if the LED Bumper flashes 4 times, that digit in the password is 4. The colors alternate from red to green to red, and the project pauses between each digit of the password to help show separation between the digits and make it easier to decode.
  • Once students have edited their project to show their new passwords, have them name their project as New Password and save it to their device. See the Open and Save section of the VEXcode GO VEX Library for device-specific steps to save a VEXcode GO project.
  • Complete Play Part 1 as a whole class experience to decode the starter password. This can help you to ensure that students understand the connection between the flashes of the LED Bumper and the numbers in the password.
