A few days ago, we decided to do some experimenting with growing crystals. Working outside on the deck, we tried 7 different methods, with a variety of ingredients. Some recipes called for epsom salts, others used bluing, and still others called for Borax. We have seen success with 5 of the 7 so far.
The green lumps are crystal growing on small pebbles and sea shells.
The white snowflake-like crystals are created by evaporation on a black piece of construction paper.
The rainbow crystals are growing on small sponges. The jar with yellow liquid has crystals growing on a pipe cleaner Christian shaped.
We also had fun painting on black construction paper with our solution and then when it dried it was sparkly.
We couldn't get one of the experiments to work, although we tried it twice. The other jar with green liquid will be rock candy but takes at least 7 days.
Christian, our resident scientist wannna-be gathered and prepared all of the supplies and was very scientific and careful about conducting the experiments. And.... bonus! We passed off a requirement for Cub Scouts in the process. It was a successful couple of hours of keeping the summer crazies away. Check out other fun ideas for kids on my side bar.
I am sharing this on Get your craft on Tuesday (even though some may argue it doesn't qualify as a craft) and Works for me Wednesday.
