Who says sugar is bad for children?! It's especially not bad in a chemistry classroom where it can be used to create flares and to bring chemistry alive! This is the 6th Beauties vs. Brawns challenge.
Challenge number 5. A dramatic decomposition reaction!
When crystals in the Chemistry lab interact, it's not always crystal clear what is happening...unless you know 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.
Gunpowder chemistry in the classroom! My first year IB Chemistry students prepare gunpowder mixture and test them. The results, of course, are quite dramatic!
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?
