The WeDo kit comes with 12 activities that start with a motivating animation, followed by easy to follow building and programming directions. LEGO Education offered a set of four Extension activities and the WeDo 8+ Projects Curriculum Pack.
There is also a fabulous developing list of activities (building projects) developed by teachers and robotics enthusiasts posted online. The list below is by no means complete and additions are welcome.
Stefan Bracher has building directions and the programme for three very cool projects – Speed Governor, Rocket, and Cable Car. Stefan even includes some rather sophisticated math to explain the centrifugal forces at work in the Governor project.
Stephanie Greer describes a mini-lesson, the “WeDo Vehicle Challenge” that she used with her 7 to 9th grade students in her after school club. Her blog includes a vehicle displaying some of the student creations.
This blog is a fantastic resource. It not only has the original 12 builds but some 20 more (and counting) with both visual building instructions and a video showing the completed project.
Fabio and Pietro Formenti have created a blog with awesome projects. The programmes for each project are available but not the building steps so users will have to figure them out for themselves from the photos and videos.
This site, by Diego Gálvez, has constructions for both NXT and WeDo. Not all of the building instructions are included (yet) for the WeDo constructions displayed. The link above goes directly to the WeDo section.
