Throwing it Back: Edible Rocks... & Giveaway Winner!

Thursday, July 11, 2013
So this week I decided to throw it WAY back... so far back this was one of my first posts. It is still one of my most popular posts thanks to Pinterest. Hah! I made this item for TPT a loooong time ago, but recently renovated it and it looks so much better. I also added some fabulous vocabulary posters.

Anyways... on to the original post.

(I deleted pictures of the original documents and added the new and improved ones! Hah!)
Original Post on February 8, 2012:

I LOVE science because it gives the students a chance to do hands-on activities. We just finished up our Rock mini-unit and I wanted to share what we did with you guys.

We began a mini-unit by defining the different types of rocks. 
Then, for the next three days we made edible rocks.
My kids LOVED it. 
The best part? I really think they learned and know the differences between the rocks now.
I gave them a short assessment to test what they knew yesterday and they all did a great job.

Day 1: 
Metamorphic Rocks:
form when rock from inside the earth is heated and squeezed.
Edible Version: To make the edible version we used Starbursts and a plastic bag. 

Day 2: 
Igneous Rocks: 
form when rock from inside the earth cools and hardens
  Edible Version: To make the edible version we used two types of chocolate chips (different colors) and a crockpot (representing deep inside the Earth). Once the rocks were melted students scooped some out with a spoon and watched the rock cool and harden.

Day 3: 
Sedimentary Rocks: 
form when bits of sand and stone are cemented together
Edible Version: To make the edible version we used sugar cookie dough (representing sand), chocolate chips, sprinkles, etc. (representing small pieces of rocks and fossils. Bake the cookie/topping mixture to represent the “rock” being cemented together.

On the final day we munched on our edible sedimentary rocks I baked the night before, and I gave them a short little assessment on rocks. They seemed to understand and I really think my students loved making edible rocks. 

Below you will find a link to my TPT store where I posted how to make edible rocks AND the chart I had my kids fill out each day as we learned about each new rock. As we were making each rock I wanted my students to be able to write down the things they were learning. 

Find this unit on TPT HERE.
Did you make it to the end? Hah!
Leave a blog post comment telling me your favorite science activity to teach.

I hope everyone has a FABULOUS Thursday!
