APTeach - Building a Test to Support AP Success Join APTeach to discuss assessment strategies that will improve your students' performance on the AP Chemistry exam. REGISTER NOW for the July 18th APTeach Session!
	Bronsted-Lowry Balloon Blast Brain Break Discover how a simple brain break activity, involving water balloon tosses, creatively reinforces the principles of Brønsted-Lowry acids and bases, making chemistry engaging and accessible for students.
Using LEGO bricks and paper springs to illustrate helical chemical structures Helical structures can be built from media such as LEGO bricks and paper. These structures can be used to model helical structures in chemistry. These include circularly polarized light and various helical biomolecules.
	Manufacture and Use of an Effervescent Antacid A question set about an effervescent antacid formulation unpacks what is occurring both qualitatively and quantitatively. The student will review and apply formulas, balanced equations, percentage elemental compositions, mass-mass calculations, mole-mole calculations, theoretical yield, and limiting reagent.
What are Your Questions? A simple shift in wording can help boost student engagement and understanding.
	Amount and rate of heat transfer using iron spheres and liquid nitrogen Iron spheres added to liquid nitrogen cause boiling as heat transfers. Boiling depends on iron mass while rate depends on surface area. This can be studied by measuring mass of nitrogen lost.
