Green Volcano
Challenge number 5. A dramatic decomposition reaction!
Crystal Clear Magic…in Chemistry
When crystals in the Chemistry lab interact, it's not always crystal clear what is happening...unless you know Chemistry!
Speaking Volumes…in Chemistry
When liquids interact, there's lots to talk about in Chemistry. In this particular challenge, my students had to figure out what happens when two liquids are mixed.
The Gunpowder Challenge: The Explosive Meet
Gunpowder chemistry in the classroom! My first year IB Chemistry students prepare gunpowder mixture and test them. The results, of course, are quite dramatic!
Mole Challenge: Can You Burrow Through This?
How do we count things that cannot be counted directly, such as the number of sand grains in the Sahara desert? And what does that have anything to do with Chemistry?
