I was such a rock nerd when I was a kiddo and it makes me so happy that my daughter has been getting into rock collecting too. When we got these, she was so excited and loved the process of breaking them open and learning about how they are created.
We used these geodes for our geology lesson. Some were easy to open, some were a bit more difficult, but the kids had a blast hammering away to open these. What was most exciting was to see what your inside would look like because of the variety included.
National Geographic Break Open Geodes has helped my kids explore geodes from around the world. The kit comes with ten different geodes with an instructions and learning guide. A fun way to learn about minerals and geology.
We just used these last week for our geology group lesson. Many different finds when they were broken open. So much fun!
