We are really enjoying being Bandai Ambassadors and all of the cool STEM activities that we have been trying out. This month we have been learning all about geodes with the National Geographic Break Open Geodes STEM kit 8+ Years. Geodes are so fascinating, they are beautiful rock formations where the cavities are lined with crystals. Typically formed from volcanic rock, but also known to be formed from other minerals such as decomposed sea life.
What you get in the kit in the National Geographic Geodes STEM Kit
A magnifying glass
2 x Geodes
A geode display stand
The National Geographic™ geodes break open kit is pretty much ready to go as soon as you open up the box. You will need a hammer and chisel in addition to the kit for breaking up the geodes.
With safety goggles on, we got stuck in. These little things are a lot tougher than we first thought. The first geode took a good 20 minutes to crack open. The key is to tap away rather than giving it a good whack or you will end up with the geode in a million pieces. Tapping away little by little will help the geode crack in half.
After 30 minutes of taping away at the second one, we finally split it open to reveal a solid rock! I’m not surprised really as this took some effort to open up! The first one opened fairly easily on the table, but we had to put the second one on the path and use a little more force.
Jayden found it really interesting to learn from the guide alongside the hands-on stuff. It’s amazing how gasses become trapped inside the lava as it cools and how water enters the holes carrying dissolved minerals, which in time, will form the inward growing crystals.
We’ve had lots of fun discovering different geodes and it’s a nice STEM activity to take outside whilst enjoying the fresh air.
