After looking at the physical properties of the five mystery chemicals, we're on to looking at the chemical properties. Our first test...how do they each react to water? Our initial results (after adding just 6 drops of water with a pipette) weren't the most fruitful. While each chemical reacted differently, students wondered what would happen if we did other tests... |
We added more questions to our Driving Question Board and agreed that the next best investigation would be to add more than the 6 drops. We agreed to 10 mL!
We're discovering all kinds of interesting phenonmena...and are seeing how these events can help identify each of the mystery chemicals. Our first test revealed that the red chemical dissolved. But what does it mean for a chemical to dissolve? We'll be working on the practice of modeling to explain this!
