About This Lesson
I made this PowerPoint presentation to use with Exploring Science. The idea is that students (in teams or pairs) race to build the molecule model (I used Molymod kits with shortlinks; but they doesn't work well for carbon dioxide). It helps the students learn about molecules and their formulae. Once they'd got going; to make it more difficult I blanked the screen after about 30 s of viewing; and later only let one team member view the image.
