The Three Types of Rocks– Our Activities and a Free Worksheet Packet about igneous, sedimentary and metamorphic rocks
A few days ago I shared the Rocks and Minerals Packet I made for ED who is in preschool. I wanted to spend more time on the three types of rocks–igneous, sedimentary and metamorphic rocks. The kids were SO excited when they realized this activity was going to include semi-sweet chocolate chips, white chocolate chips, peanut butter chips, heath crunch bits and flaked coconut. (No we didn’t eat it all, but we did taste test a bit along the way!) I used that as leverage to make sure the rest of their work was done for the day!
I made some worksheets for their science notebooks. Before beginning our activities, we went over the differences between the three types of rocks (the first page) and sang our song again (below). We saved the examples (the pages with the pictures of various examples of rocks) for another day. The packet includes some sample example answers for each page (such as the metamorphic rock page in the collage below). This packet also includes the activities I shared below.

New Rocks and Minerals Unit!
The material above was made many years ago when my kids were quite little. We have made a huge new 100+ page Rocks and Minerals Unit!
New! (2021) We have a fantastic Rocks and Minerals Packet available. I’ll leave these pages (above) that I made many years ago still up on the blog, but you may want to check out our new Rocks and Minerals Unit here at this post or scroll down below.
In our Rocks & Minerals Unit, we went into a lot of detail about the types of minerals, identifying minerals – crystalline structures, the characteristics of minerals (color, streak, luster, hardness), the Mohs Hardness Scale, how rocks are formed, weathering, erosion, the lithification process, different types of igneous, sedimentary & metamorphic rocks and more. This packet includes notebook pages, worksheets, a lapbook, lab activities, vocabulary cards, booklets and more!
$7.99 New! Rocks and Minerals Unit 100+ pages

This unit is included in our Earth Science BUNDLE. More details about the Earth Science Bundle options here:
Here are more pictures of what is in the Rocks and Minerals Packet:
Our types of rock ‘experiments’
We had different types of chips: white chocolate chips, semi-sweet chocolate chips, peanut butter chips plus shaved coconut and heath crunch bits.
Igneous Rocks: We melted some white chocolate (and red dye) on the stove. We talked about how magma/lava is melted rock. Then we took spoonfuls of the melted chocolate and let it cool on a baking sheet. These were our ‘igneous’ rocks.
Sedimentary Rocks: Before we began, we hammered the chips in a ziploc bag to make them smaller. We put spoonfuls of the different types of chips into a jar. Those were the sediments. We applied pressure to squeeze the rock/chocolate layers together to create sedimentary rocks:
Here are a couple of other activities we did when talking about sedimentary rocks:
Metamorphic Rocks: We put layers of chocolate chips and mini-marshmallows into a pan that could be baked in the oven. We put the pan in the oven and let it heat up for 10 or 15 minutes. We took it out, let it cool for a few minutes and then applied pressure to the top of half the mixture. This transformed the “rocks/chips” into a new concoction whereas on the other side we could see distinct layers and distinct rock forms (like sedimentary rocks).
After it cooled we cut the “rock” up and looked at the layer, noticing how on the metamorphic side the “rocks” had blended into one another.
You can do these same kinds of activities with shaved crayons. I saw that over at The Adventures of Bear they did the rock cycle with crayons and had some really great results! Be sure to check it out!
Rock Cycle Song
I’m sorry to say I can’t find the exact link to this song, so if you know who I should give credit to let me know. The kids and I have been singing this all week (to the tune of “Row, Row, Row Your Boat”):
Sedimentary rock
Has been formed in layers
Often found near water sources
With fossils from decayers
Then there’s igneous rock
Here since Earth was born
Molten Lava, cooled and hardened
That’s how it is formed
These two types of rocks
Can also be transformed
With pressure, heat and chemicals
Metamorphic they’ll become
For this unit, we used two books in particular for our hands-on activities:
We really loved Explore Rocks and Minerals!: 25 Great Projects, Activities, Experiments (affiliate link)
Geology Rocks!: 50 Hands-On Activities to Explore the Earth (affiliate link) was really great for the age of my kids. It had a lot of really fun ideas. We got it first from the library, but then I wound up purchasing it to have on hand!
We got a number of other books, but the one I highly recommend is Smithsonian Handbooks: Rocks & Minerals (affiliate link) because of all the beautiful photos.
And one last recommendation if you have younger kids (preschool age), my kids really liked Let’s Go Rock Collecting (Let’S-Read-And-Find-Out Science. Stage 2) (affiliate link)
We also got a rock kit with different samples of sedimentary, metamorphic and igneous rocks. We got the small version (with 15 rocks): American Educational Introductory Rock Collection (affiliate link).
The large kit with 75 rocks and minerals looked really great: Introductory Earth Science Classroom Rocks and Minerals Collection (affiliate link). For a rocks and minerals unit for older kids, I would probably got with this because it has at least 25 minerals, some ores, and samples of the sedimentary, metamorphic and igneous rocks.
