Science Friday: Making Crystals

Our Young Scientists’ Club subscription has been really fun so far. This week we worked on the Crystals kit. Emily started by attempting to break a geode. She wore her safety goggles but that thing just wouldn’t break…

Finally we took it outside and she placed it on some concrete. Then she was able to break it. She was a bit disappointed that it had no colour inside, but it was still pretty.

Next we had to make some recipes for crystal solutions. These were put into jars. She tied paper clips to string and attached them to popsicle sticks to suspend them in the solutions. We are still waiting on our crystals to fully form, but she did enjoy a small taste of “rock candy” today!

Here are some shots of her work:
