Using two pieces of cardboard and a few other basic materials, students built their own "articulated robotic arm" to perform some basic tasks. The challenge was for their robotic arm to be able to grab some items of various weight out of a bucket a few feet away. Students were up for the challenge!
First students read about the robotic arm on the Space Station and the many ways it helps the astronauts.

Next, students got comfortable with some key vocabulary they should be using while building such as "articulated" and "performance", and "task". Students then built and modified their arm. After they felt confident with their arm, they tried to pick up materials.
Our last step was reflecting on our engineering using a message board on Dy'Know.
This lesson was modified from:
First, building....
Then testing...
The materials in a bucket for the "arm" to pick up (rings, rubber band, small cup, foam block, scissors and more....
Success!
Great Job Champions!
