After showing the students about gears using the DUPLO size ones
they made the AIMS Governor Rules project.
When a gear with many teeth drives a gear with few teeth the output is fast.

Investigating Gears: It's No Mystery to Us!
Quote from Mrs. Blackman's BLOG-

"Today our 4th graders worked diligently on a logic problem about nutrition (and the lack of!).
Then we investigated gears with Mrs. Linda Hamilton from Marshall's LEGO lab.
We constructed a "governor," a device that helped regulate a train, and then used different gear configurations
to see which arrangements produced the fastest and slowest spins and which were hardest and easiest to crank.
This took cooperation and analytical thinking!"
