English Club : Geodes

What is a geode? A geode is a rock which has holes in, through which minerals have flowed through in water, and thus formed crystals inside. A process that can take millions of years.

The kids observed some geodes…

…before opening their own (a process that took 2 minutes with one geode, and 40 minutes – and a lot of teamwork, with the other!)….

We then went on to start our egg geode experiment, using alum, which we would continue the next week..
