Chemistry 1 – We continued to practice the “domino” method for converting measurements into different units. Groups first whiteboarded a problem from the introduction activity we did yesterday, and then continued to practice unit conversions in the metric system by still setting up dominoes.
Physics 1 – Ranking Task Debate. Groups were given the 6 position vs. time graphs above. They were asked to rank the graphs from greatest to least for displacement, distance, average velocity, and average speed. Each small group came up with their ranking and then the large group debated. I wanted one final ranking reported to me. Above is what one class decided on. The only real issue I needed to settle was if something that moves 15 m in a negative direction is displacing 15 meters or -15 meters.
Chemistry 2 – Groups shared their particle diagrams comparing Strong vs. Weak Acids/Bases and Concentrated vs. Dilute Acids/Bases. These particle models were mostly based off of what was seen when using the PhET Acid/Base Simulation. One group chose to compare using a Venn diagram.
