![]() When the tilt sensor shows a value of 3, students can determine how many degrees equal a value of 3. When the distance sensor shows a value of 2, students can measure with a ruler the distance and chart the values. The LEGO WeDo components also give numerical indicators on the Scratch Screen of distances and tilt values that can be transferred into authentic data. ![]() The new Science Standards of Learning in Virginia indicate students must have an understanding of probeware, sensor, and accumulate data. Using LEGO® bricks, easy-to-use software and engaging STEM projects, teachers have all they need to teach their students simple programming skills. Only compatible with Chromebooks WeDo 2.0 makes coding a reality for elementary students. The robotic LEGO WeDo components that work in Scratch are a Distance Sensor, The Tilt Sensor, and a rotating Motor. The LEGO® Education WeDo 2.0 App allows students to explore great science projects. Many of these projects require teachers or upper-level students to build the components, but once built the storytelling capabilities are incredible. Skiing Moose Ferris Wheel – I wish they would post the LEGO designs for the arm-swinging moose.Caterpillar Love Story – AWESOME storytelling.Fatman Protagonist -interactive balancing and storytelling Balancing Robot – I wish they would post the LEGO designs so we can build the same bot.Submarine Rescue – interactive adventure.Scratch Screen and LEGO Customized WeDoĬomplex projects were created at the MIT Lab and you can download the Scratch Files: Our challenge was to create a way to make sure the platform stops at a safe level without knocking off the LEGO men. We modified the motor project to lift a platform of LEGO Men provided from the WeDo kit. These intro projects give easy-to-follow LEGO directions within the Scratch window. The Scratch website also has starter projects and setup instructions on how to use each WeDo Component. Scratch provides emulators where you can see the screen-programming in action (letters will change colors when you click them), but without the robotic LEGO WeDo motor and duck attached tethered to your computer, the program will not make sense to someone interacting with the screen (I have received comments saying that the program does not work from the sharing-Scratch community). If you have a motor raising and lowering, you need to put an interface on the screen to explain what is happening, and if the interface is interactive, we are hitting the core-level of robotics understanding that we originally were going over student’s heads with NXTs because the software-hardware-interaction was not immediate.Īn example program I created is called updownduck where a physical LEGO Duck is raised and lowered by clicking the words UP and DOWN on the screen. Directly plug in the LEGO WeDo USB to the computer with pre-loaded free Scratch drag-and-drop the robotics components will automatically appear in Scratch. LEGO Software is available for younger students, but Scratch programming has inherent drag-and-drop blocks that resemble MIT App Inventor interfaces for Android Phones that my advanced students have been using. ![]()
