Summer SAVY 2016 (Session 5, Day 4) – Marvelous Molecules (Dr. Zeiger)

Posted by hallep on Thursday, July 28, 2016 in Grade 1, Grade 2, SAVY.

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!
