This sequence of activities introduces the basic LEGO system pieces. It’s great for beginners and works well with young children. It also introduces the concept of testing and redesigning. How can we build a sturdy wall? Study tower Strongest shape Sturdy Car: The drop test Chair for Mr. Bear See...
This suggested sequence of activities begins with an exploration of simple hand-powered gear trains. The second and third activities use gears to decrease the rotational speed of motor-powered music boxes and fans. The last three activities incorporate gears into cars so that they can win a “snail race” or climb...
The WeDo kit can be used to achieve many curricular goals. The guide that comes with the WeDo software provides ideas of how to achieve mathematics, science, technology, engineering and language arts goals. Other teachers have also developed their own curricula using the WeDo. The list below is not complete...
To keep the WeDo simple and easy to use for younger children, the WeDo doesn’t have an intelligent brick in its building materials. No intelligent brick, so no programming and no power. The USB hub is there to provide both from the computer. But, wouldn’t it be great to be...
Design and construct a working music box in which LEGO mini-figures move while a song plays. This lesson is one in a series of introductory lessons that is applicable to all types of robotics kits. The lessons are geared to students in early primary to middle school (depending on the lesson). Additional...
Design and develop a car that is capable of traveling across flat surfaces quickly, but can also negotiate a steep ramp. Note: The WeDo version of the car remains tethered to the computer via the USB cable and therefore cannot travel very far. Tip 1: What gear train yields...
What is the best design for cars used by people on sloping paths? Construct a car that is capable of climbing steep inclines. What is torque and why is it important? This lesson is one in a series of introductory lessons that is applicable to all types of...
The idea of this challenge is to design and construct a car that can move extremely slowly. These cars must compete in the snail race; the winner is the car that crosses the finish line last. Note: The WeDo car stays tethered to the computer via the USB cable so...
The RCX constructopedia (PDF, 55Mb) includes an extensive set of instructions designed to introduce beginners and advanced builders alike to new concepts in building with the RCX. 418 pages! Contents include: Stationary builds Sturdy structures Bracing Change axis Moving parts Motors Gears Pulleys Special gears Cam Differential Worm gear Gear rack...
How do gears interact to vary torque and angular speed? Build different gear assemblies to discover these effects. What do the terms “gear up” and “gear down” mean? This lesson is one in a series of introductory lessons that is applicable to all types of robotics kits. The lessons are...
