Summer SAVY 2016 (Session 5, Day 4) – Marvelous Molecules (Dr. Zeiger)
Students were mixing it up today as they explored the world of chemical reactions. Using a variety of different chemicals including acetic acid and starch, students found evidence that chemical reactions were taking place. This included an exothermic reaction, color change, gas formation, and a precipitate. Ask your student how we switched electrons around to create sodium chloride. Next, we investigated how to speed up those chemical reactions and found that temperature, surface area, concentration, and a catalase can really speed things up! Its amazing how a potato can help hydrogen peroxide break down into its separate parts! See you tomorrow when we learn about some “big bangs” in chemistry!
