DSC_0120 This week at Woodson, the girls of Sisters4Science got a visit from Ms. Bori Kim, one of Project Exploration’s STEM Facilitators! Bori has done many experiments with Sisters4Science programs at other Chicago Public Schools so it was great to see her again at Woodson! For the activity of the day, Bori facilitated her super fun experiment on density! For this experiment, the girls were given corn syrup, vegetable oil, water, cashews, a candle, and milk and asked which ones they thought would sinkApril 15 - 14 furthest to the bottom. By using guess and check and what the girls knew about density, the girls were able to test which materials they thought would float in water and which ones they thought would sink. Stephanee guessed that the candle, despite being the biggest object, would float to the top because it has such a large surface area. Looks like someone’s been paying attention in geometry! The girls had fun messing with all of the materials and were even able to add food coloring to make their creations even more exciting!
To have a bit of a brain break, the girls played a round of my favorite game, Ninja! Because some the girls had never played the game before, we had a bit of a rough start.

That’s basically as good as a black belt!
