Rock Sensory Bin
Part of one summer, we did a lot of collecting of rocks or different colors and shapes. And we got them from a lot of the places that we visited, which had collected rocks you could buy in little bags.
We got bags of rocks from various places. We wanted to do something fun to play with them. So all the rock were put in a rock sensory bin with a fun black rock filler.
A super easy to use up sensory bin and a fun to explore sensory bin for kids.

The Rock Sensory Bin is a great addition to the sensory bins on the site.
What is a sensory bin?
A sensory bin is typically a plastic tub or container filled with carefully selected materials and objects to stimulate the senses of children in preschool.
Sensory bins might have rice, water beads, corn, beans, or other types filled with small items.
Rock Sensory Bin
We took all the rocks we gathered over the summer and put them in a rock sensory bin. We use black rocks as the fill with the colored rocks to explore.
We had fun exploring the texture and colors of the rocks. This is a great sensory bin for kids in prek (ages 4 to 5) and kindergarten 9ages 5 to 6).
Books to Read with the Rock Sensory Bin
We also read about some rocks in the book: Rocks, Fossils & Arrowheads (Take Along Guides). We talked about the different type of rocks that you can see. This was fun to read before hand so we knew about the different types of rocks.

We also read the book Everybody Needs a Rock (An Aladdin Book). This is a great ideas about picking out your own rock. We have grown to love this book. I really like #2 in the book. This makes for something fun while playing in the sensory bin and picking out rocks.

Ways to Use the Rock Sensory Bin
These are just a few ideas to use with the Rock sensory bin. And remember that you might have more ideas to do with the rocks.
Play in the Rock Sensory Bin
The most important part about a sensory bin is to PLAY in the sensory bin. It is a simple activity for kids to do to explore different colors textures and just play with the rocks. And if they do nothing else that is okay!
Explore the Different Colors of Rocks
My youngest started out just looking through the bin and exploring what kind of rocks she could see. She loved exploring the different textures of the rocks.

She then started sorting out some of the different rocks. She sorted them by color, similar rocks and colored vs the plain black color.
You could also learn about the rock cycle using the rocks in the sensory in.

Compare What Is Different and Same
We did some simple what is the same and what is different with two different type of black rocks. We had shiny rocks and glossy rocks. It was fun to look at. We noted shape and size.
This is great for older kids to look at the rocks and write what is different about them as well!

Sort the Rocks
She sorted the rock in the bin. She had same colored rocks on one side and color or fancy rocks on the other side. Once they were all sorted she used the black rocks to cover the fancy rocks.

We Used the Rocks on a Dot Maker Letter R
We also used the rocks from the bin to help fill in the dots on the lower case r is for Rock Dot marker page.
Remember That All Ages Like Sensory Bins
This was a really fun and simple sensory bin! She loved it a lot. Her older sister also like to play with the Rock Sensory Bin as well. They all took their turn and pulled out and sorting all the different colored rocks.

What beautiful rocks! I bet the cool, smooth texture made for a great sensory experience!
I love this idea for a sensory bin – we have a whole jar of rocks and shells on our kitchen windowsill and I now know what to use them for 🙂
Excellent!!!
I’d love to play in your rocks, too! The smoothness of even your filler rocks looks really appealing and makes me want to play!
Such a great idea! My boys have been collecting rocks for years now, and have accumulated quite the collection. This would be a great activity for us. Thanks for sharing!
