Drinking Dinosaur Pee?! It has been claimed that because all water ultimately ends up in the water cycle, we drink water that the dinosaurs peed out. What does chemistry have to say about this assertion?
	Thought-Provoking Capstone Demonstration for the Chemical Reactions Unit Try out this though-provoking capstone demonstration for the Chemical Reactions unit!
Using AI to Source Phenomena Nora Walsh asks Chat GPT to help create a list of potential phenomena to incorporate into lessons.
	Stoichiometry with Beads Teaching and learning the concept of limiting reactants can be challenging. In this activity students manipulate beads to learn about stoichiometry. A virtual drag & drop version is also available.
Using Visual BCA Tables to Teach Limiting Reactants Looking for a better way to teach stoichiometry? Melissa incorporates modeling into BCA tables in this post from 2017.
	Tissue Paper Banners Connected to Chemistry Tissue paper can be folded and cut with chemistry-related patterns to make decorative paper banners that can be used as Mexican-themed decorations. Chemistry concept connections include lattice energy, bandgap energy, and ionic crystal fracture.
