We can all make a paper airplane, but can you design a paper airplane that can carry "cargo" pennies? The girls planned their designs, tested them, tweaked them, and tested again. They recorded their distances in proportion to the weight, in grams, of coins that their paper airplane could transport. This is a fine example of persistence... If at first you don't succeed, try, try, again!

In today's meeting, the girls used kits to design their own roller coasters, testing out new heights, new paths, and new arrangements of the track to create optimal scream-factor in a way that wouldn't compromise the car's attachment to the track. Another group made a mini roller coaster using tiny balls as the roller coaster cars, in a Rube-Goldberg-esque expedition in learning. Check it out! For this project, Kareena, Ashley, and Emily worked together to construct a solar powered helicopter from the kit that was provided by STEM Girls. The instructions came in Japanese, which certainly made it more challenging, but the girls found other ways of understanding them. They put together each tiny piece and later on, when it didn't work quite right, used the skills of future engineers and found ways to improve what they had created. Great job, girls! In this project, the girls learned how to follow directions, while also being able to be creative and make good engineering decisions. From kits provided by STEM Girls, the girls broke into pairs and designed a car with a motor that was powered by the sun. |
