We started off our unit with three different centres to classify the three types of rocks; igneous, sedimentary and metamorphic. Anything hands on is always a blast!
Now, anything hands on that involves candy....well, that just makes me the best teacher ever! I was thrilled when I found this idea!
I used Power Point to create a slide show with the different steps to this activity. Prior to the lesson, I made the igneous rock myself, using three Starburst candies and a microwave. I didn't do this step with the kids because I didn't want them to burn themselves and getting 29 students to use 1 microwave was just not possible.
The first rock we made was the sedimentary rock. The kids cut up their three Starburst candies with scissors. Some made tiny pieces, others were happy with just cutting them into quarters. Then, we pressed the "sediments" together to make a sedimentary rock.
We then warmed up our "rocks" in our hands and by blowing on them. It didn't take long for the candy to get warm! We folded it a few times and we had "metamorphic" rocks!
The kids made the connection between the three types of rocks and how they're created. What an awesome lesson that was! Everyone, every single one of my 29 (yes, 29!!) students was completely engaged for the entire lesson!
Here is the lesson plan, PowerPoint presentation and worksheet that I created for my students! It's also available in French!
The entire Rocks and Minerals unit is now available! Check it out for more fun, hands-on activities and lessons, plus 3 assessment tasks with rubrics!
