Grow Rock Candy
The best way to study crystals is to make your own! A hands-on lesson shows learners how to make their own rock candy from household materials. While they watch the crystals grow, they discover their structure and can even eat their...
Science Friday
Mineral Madness
Science does not need to be as hard as a rock. Pupils test 10 different minerals to determine their properties. The learners observe luster, streak, hardness, and fluorescence for each specimen. Afterwards, they compare and contrast the...
