I followed the Stemillions session plans - and I loved them! I had a feedback session with my girls, and they loved the plans, but they wanted more experiments!
I kept the parts about the meal plans they liked: hearing about the women in STEM role models. My girls said they wanted to learn more about refraction, so I asked one person to research and find a role model and I would use it to plan the session.
We have a journal that we document each session in. After each session, I gave it to a different girl and she wrote about the session. This was the CEO of Refraction Media's spread in our journal!
