Rocks/Crystals: part 3

More on rocks and crystals!  
We have been talking about the different shapes crystals can be.   We looked at close up pictures of salt and sugar, and we looked at the crystals we grew from Borax with magnifying glasses.  

This is a model of a crystal we put together:  (green thing is an eraser)

Levi tried out the "scratch test" on the back of a tile he found in the garage.   He was disappointed to discover his "big chunk of gold" was fools gold!   It had a black streak, not yellow.  

And, lots of fun, he hammered geodes.    I got these at a garage sale a long time ago, but they can be ordered online lots of places too.    We talked about how geodes are formed:   water containing minerals seeps into "bubbles" in rocks,  the water evaporates, leaving crystals behind.   Sometimes the process happens multiple times leaving layers of crystal that can be different colors.  

Fort Wilderness, the Wilderness Lodge, and more rocks!

Levi was invited to a bday party at the Disney campgrounds, so we spent the day there enjoying the area, and then having a great time at the party!    It was our first time there and we decided we would like to camp out sometime.     Even on a fun day out we managed to find some learning along the way.

Levi LOVED playing dodge-ball.   A sport that combines my least favorite things to do - running around in hot sun while balls are being thrown at me.    I just watched.     Levi played the entire time they had a game going and had the "best time ever" according to him.     

We stayed for the camp fire, they had a sing-a-long, with marshmallow roasting (we brought our own allergy friendly/vegan ones).   They do a movie after but we left before it started.  

Sing-a-long face I guess?   

And Levi met his friend Dale.   

And here is where we found some rocks!     At the Wilderness Lodge, they have a display of a bunch of real rocks in a case:

And these rocks match up with rocks that are in layers of the Grand Canyon, which we had just been talking about.   
Even more fun was the giant fire place they have in the lobby next to this display.   It represents the layers of rock, just like a giant model of the Grand Canyon page Levi colored.        It was so big I couldn't get it all in the picture

So even at Disney, you can learn about rocks.  

Grand Canyon (start of our rocks/minerals/crystals study)

I've decided to do something a little different with blogging about our current unit study.   Instead of posting all at once when we are done, I will post as we go, so that I don't get overwhelmed or forget anything!  

This unit study is on Rocks, minerals, and crystals.   I'm trying to focus just on those elements so that we can do a "land formations" type study after this one, but there will be some overlap! 

To start, here is my pintrest board of inspiration, resources, books, lapbook stuff, unit study stuff, etc

We are reading the Magic School Bus chapter book, Rocky Road Trip, and using the lapbook from Ye Shall Know that goes with it.  

First, Levi read a book about the Grand Canyon from the series "Adventures with the Parkers" .   This sparked his interest in rocks in the first place.  I  had never heard of this series before, but already we have 2 more checked out from the library and another ordered off ebay.    This series is about 10yr old twins who go to different National Parks.    They are stories, of the kids adventure through the park, but throughout there are "boxes" that include real facts.   The stories themselves are all about actual locations, plants, animals, history, land formations, etc.    The pictures in the book are both real photographs and drawings of the characters and what they are doing.   Its a wonderful mix of fact and realistic fiction with lots of educational value while still being high interest.  

This is the one Levi read


Levi did some artwork, Grand Canyon style.   I found the inspiration picture on pintrest, and didn't realize until we were done that there was a lesson plan for it!   I used to teach art classes in a "step by step" style that teaches different techniques, so I used that method to make my own lesson plan for it.   It came out wonderful! 

 


Because the Grand Canyon is in both the books Levi read, we have been talking a lot about it, the rocks, how it was formed etc.     Levi did this fact sheet, and we used this idea about erosion/sedimentary rock formation, and the formation of the canyon to do an experiment. 

First, he filled a tray with sandy soil (any dirt/sand should work)

Then draw a line down the center with your finger and add the hose:

 



You can see the deepening/widening of the canyon/riverbed in the center, watch erosion happen as the sides gradually break away, and see the "sediment" that ends up at the bottom of the river.  

We also did this experiment to learn more about sedimentary rocks with layers of dirt, sand, rocks, and whatever was in the compost.  And we have these geodes starting to form, Levi was anxious to start that experiment!

That's what we have done so far!    We have plans to make our own rocks, and do some other experiments so I will share those as we go.
