Students made several observations of their crickets and fish today. We worked on making sure our observations were in fact observable facts.
Then students tested pH levels on water and vinegar, in preparation for an experiment.
Students then began demonstrating curiosity about the pH level of various things. Their questions reiterated my belief that "teaching is listening." I knew it was time to scrap the lesson plan. And our young scientists tested pH on all that they could. Yoni even asked if he could go outside to collect rainwater to test its pH level!
Afterwards I asked students to reflect on something new they were thinking about as a result of this.
Maya wrote: What else could I test for pH? What would have low amounts and high?
Emma wrote: I never thought spit would make the pH paper so green... I never thought that vinegar had so much acid.
