We did this fun experiment in our classroom last week and let the crystals grow for a week. It was fun and it goes along with our unit on Rocks and Minerals. Here are some samples of our cool Salt Crystals experiment.
I used a briquette and then we cut little evergreen tree shapes out of cardstock and glued them on bowls next to the briquettes. Then we added solution and food coloring to both. And let them sit for a few days. This is after about 2 days.
|We sent home the directions for our experiments too. We also looked at salt crystals and sugar crystals under viewers on black paper and did some Water Jelly Crystal experiments too. Fun!|
I have this book in my class. I tell the kids all about this old timer photographer who took old fashioned photos
of snowflakes and proved that no 2 were exactly alike when their crystals formed. I also have a copy of
his book, where he photographed hundreds of snowflakes. It was interesting to share. Our crystals kind of look like snow or snowflakes.
|This one turned out the prettiest with all the colors of the rainbow and some pretty good growth. All the kids made one and took it home.|
|I searched for lots of experiment ideas on the internet for this newly developed unit. I've not had to teach rocks before. But I think we learned a lot about them. Check out my 3 Types of Rocks Flapbooks we made too. They are cool.|
Here they are ready to take them home after a week. They looked pretty cool. We talked about gems
and crystals and how they are found in metamorphic rocks which are under a lot of heat and pressure. That's how
diamonds and many expensive gem jewels are made.
counter and kids could view them several times a day. Everybody had their own.
Here they are after a weekend....a few still had some sediments in the bottom.
