For example, we're working on a weather extension that will allow your projects to get the current temperature in any location. And with “Web extensions”, you can pull data from the web into your project. What are Scratch Extensions? The WeDo extension is just the first of its kind: It will soon be possible to connect other kinds of hardware to Scratch. If you have a LEGO WeDo, you can add the WeDo extension by clicking the more blocks palette, and then select “add an extension.” Select LEGO WeDo and follow the instructions to install the plugin. When the tilt sensor shows a value of 3, students can determine how many degrees equal a value of 3.Today's update to Scratch adds support for the LEGO WeDo - a first for Scratch 2.0! LEGO WeDo is a robotics kit that you can use to connect your Scratch projects to the physical world. 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. The robotic LEGO WeDo components that work in Scratch are a Distance Sensor, The Tilt Sensor, and a rotating Motor. Many of these projects require teachers or upper-level students to build the components, but once built the storytelling capabilities are incredible.
