Looks like this week’s theme is: ALGEBRA We were working on finding the average atomic mass of elements’ isotopes. This involved percentages, solving for one unknown…and solving for two unknowns. Most students were comfortable with percentages and solving for one unknown. Once we got to solving for two unknowns, we kind of gave up. ThereContinue reading “Day 15: Chemistry and Algebra”

Class 5: Density & Balloons on a Friday
To teach density in alignment with modeling instruction, I would have had students find a material’s density by measuring various mass and volumes. The density labs generally have students identify the unknown substances by comparing calculated density to known values. While what I envision would have taken longer, it would have allowed students to trulyContinue reading “Class 5: Density & Balloons on a Friday”
Chemistry Day 3: Safety & Equipment Quiz + Matter
We had the General Chemistry students take a Safety & Equipment Quiz. They must pass it in order to participate in the labs. Students generally thought this was a fair deal. The quiz had a portion where they identified some lab equipment. We all switched it up for each of the blocks so that noContinue reading “Chemistry Day 3: Safety & Equipment Quiz + Matter”
