This was not a good day for me--I made it through fifth period, and by the time lunch was over I was on my way home. Perhaps it was a chemical reaction gone bad, but I was out for the count. I showed a video on explosions to the classes I missed in the afternoon; I hope you learned a bit about chemical reactions in my absence.
I feel better now, later in the day. The best period of the day was the O1 section and the hydrogen bark lab. In this packed lab, the students used a chemical reaction between HCl and magnesium and calcium to produce hydrogen gas, which they stored in test tubes and then set on fire at the end. It had everything students want: fire, explosions, strong acid and bubbles (of H gas). We will be discussing the reactions in the following week, learning more about what happened as we learn to read chemical equations.
In the L section, I had a massive headache, but we did make progress, going over the review homework 5-6 and learning how about oxidation numbers and how to combine atoms to make compounds. By the end of the period, I think most students had a good understanding of how compounds arrive at the ratios they have. We will go over it again tomorrow and make sure, as well as take the Unit 5.1 quiz.
Sweet justice for ibuprofen.
