How it works: A team of volunteers visited Olney Elementary School twice during the 2015/2-16 school year. Partnering with science teachers there, we took over the 5th and 6th grade science classrooms and engaged the students in laboratory experiments.
What the kids did: Our four experiments centered around the Next Generation Science Standards, and focused on key physical science concepts.
- In the fall, the 5th grade students learned the difference between chemical and physical changes and found out that chemical reactions come with interesting physical changes as well.
- In the fall, the 6th grade students learned the difference between chemical and physical changes and used observation of those changes to solve a mystery.
- In the spring, the 5th grade students contrasted three different 'recipes' to make bouncy balls - a chemical reaction! Students then quantitatively compared the recipes to see which recipe works best.
- In the spring, the 6th grade students learned about electrochemistry. Students used home-made electrochemical cells to plate coins with different metals.
The team: The team was composed of graduate and undergraduate students from Philadelphia-area universities including the University of Pennsylvania, Temple, and Drexel.
