Quartz Study - Rock Collecting Gone Crazy

Our quartz study has stretched on for weeks. We have had numerous rock collecting hikes and each time we come home we develop new questions to be answered. The supply of quartz in our area is seemingly endless. Once your eye starts to look for it...you see it everywhere.

Our family lives in the gold country of California. The gold rush started practically in our backyard. We drive by the American River every day...as the crow flies it is about 3 miles from our house. This area is full of old gold mines and many people still today make a living by mining and panning for gold (or using a sluice box). Where there is gold, there is quartz.


We collected milky quartz for the most part at the river, along with a variety of other "pretty" rocks. I have a special place for pretty rocks in my heart. It may be the hunting for them or the spotting of a particularly nice rock that keeps me coming back for more.

Mr. A shares my love of rocks and we enjoyed an afternoon this week at the river with the Kona dog. Kona likes sticks more than rocks so we occupied her with fetching sticks while we looked for something interesting along the rocky shore.


The sound of rushing water always seems to welcome a good thoughtful sit..even on an uncomfortable rock. This day we sat and enjoyed the warmth of the sun after a freezing morning. Our jackets were slipped off on the hike back to the car which was nice. 

At home we started off with a magnifying lens, looking carefully at the surface of each rock. This can quite addictive once you get started and there really is a lot to see.



We noticed a colorful collection of sand on the surface of one rock and we had the bright idea to place it on a slide and look at it under the microscope.




We are still not sure if the shiny gold is actually gold or pyrite....probably pyrite flakes.


We placed a little sand on a microscope slide...our rocks all had small amounts clinging to the nooks and crannies.


Now this is where the study becomes even more interesting! We spent the next hour or so taking turns finding things on the slides to share with each other. It was like discovering a new dimension.

We now have a larger collection of quartz and pretty rocks, a growing understanding of what "sand" is after looking at it under the microscope, and an appreciation that we don't know everything about everything. :)


Amazing world down there...who would have thought?


It is not too late to do your own study of quartz using the Outdoor Hour Challenge. You may be as amazed as we were.

OHC More Nature Study Book 2 - Quartz Study

 “Quartz is the least destructible and is one of the most abundant materials in the crust of the earth as we know it. It is made up of two elements chemically united—the solid silicon and the gas oxygen.” Handbook of Nature Study

Rock Study - Quartz Crystals
Inside Preparation Work: 

1. Read pages 754-755 in the Handbook of Nature Study (Lesson 213). This short lesson is packed with information and the lesson suggestions will give you some careful observation ideas. 
2. If you can locate some quartz samples to have on hand, do some close up observations of quartz. Even little ones can describe with words their quartz sample. Compare quartz with some other rocks in your collection.
3. If you do not have samples, make sure to view the images of quartz with the additional links provided below. 

Outdoor Hour Time:

1. If the weather allows, take your outdoor time in a place that has rocks to pick up and handle. Be on the lookout for quartz crystals. Do not be discouraged if you can’t find quartz in your neighborhood but take the opportunity to observe and describe any rocks you see. 
2. Collect a few rocks to bring home and either start or add to your rock collection. 

 
Follow-Up Activity:

1. After your Outdoor Hour time, take a few minutes to follow-up your outdoor time. Bring out your quartz samples and compare them to other rocks you may have collected. Set up a rock observation spot on your nature table. See the image above for ideas. 
2. Give time for a nature journal entry or ebook users can complete the quartz notebooking page and/or the coloring page to follow up this study.
3. Advanced study: Research more about quartz on Geology.com. Use a printable Mineral Chart for additional information and identification. Learn the identifying marks of quartz. Record your information in your nature journal or a notebook page.

Our Nature Study Week - The Familiar and the Surprising

Want to know what I love about walking a familiar trail? I love knowing where things grow, the landmarks to notice, the way you can tell that something is different. Usually this is the changing of the season, seeing the plants grow, blossom, and then die down in the fall. Sometimes it is a man-made change and it is shocking!



This is where our star thistles, Queen Anne's lace, and sweet peas grow in mass every spring and summer. We haven't been on this section of the trail in a few months and were were surprised to see that they had cleared it off, inserted a culvert and pipe, and then recovered it with this material. We are wondering what they reseeded it with. I can guarantee it is not star thistle, Queen Anne's Lace, and sweet peas.

I dug up a photo from a previous season.



Our family used this spot as a landmark. I could say to the boys as they ran on ahead, "Stop at the thistle spot." Now we shall have to see what grows and make a new landmark. I know I will miss my Queen Anne's lace.



Another change we see is in our bird feeder attendees. This year we are seeing Anna's hummingbirds everyday in our feeder. They are coming and going all day long. Several of you have noted the hummingbirds on my monthly bird list. This species (Calypte anna) is an iridescent green and gray below...the male has an iridescent red head and throat. If you catch a glimpse of them in the sunshine, you are amazed at their dazzling color. They stay all winter even in the sub-freezing temperatures. I go out to check their feeder each day to make sure it isn't frozen.




We took a walk around our yard last week as part of the Preparation for Winter-Plants challenge. This challenge had us looking for ways that plants get ready to survive the cold winter temperatures. We noticed that several of our plants are putting out a new bloom. This Moonshine yarrow is very pretty..especially up close.



One plant that is surprising us is our yellow rose. It is still blooming...not the prettiest of blooms but still treating us to some rose-goodness for the kitchen table. For all you Redwall readers out there, we have named this the Winter of the Rose.



As part of my research and preparation for the new More Nature Study #2 ebook, we are having fun studying rocks up close with our magnifying lens. I set up a spot on our nature table with some interesting rocks and I noticed that just about everyone has stopped by to take a peek. (Quartz will be a topic in the new ebook.)We have lots of examples of quartz in our rock collection so pulling them out and putting them in one place has brought them back out of the shoeboxes and into the spotlight.

We are headed into another week of dry sunny days so we will be outdoors walking quite a bit. I know at some point the rain and snow will come but for now we are breathing deep the warm (50's) afternoons together. Hope you get the chance to be outdoors this week.
