Collect Your Own Drosophila Lab
Learners study Drosophila by catching them. They construct catcher-containers to catch Drosophila using fruit as bait. After collection, they examine the flies and collect data to be displayed.
Cornell University
Catapults
Ready, aim, fire! Launch to a new level of understanding as scholars build and test their own catapults. Learners explore lever design and how adjusting the fulcrum changes the outcome.
Cornell University
Catapult
Studying levers couldn't be more exciting! Learners build their own catapults and test the results as they make adjustments to the fulcrum. They compete against other groups to create the most accurate apparatus.
