As part of our winter unit, Kathleen's class made crystals this week. Sugar, salt, and snowflakes are examples of crystals...so is borax. Borax, a cleaning product found in the laundry aisle, makes (almost) no-fail crystals.
On the first day, we mixed hot water and borax. The kids wrote their names on craft sticks and made designs with pipe cleaners.
After pouring the borax solution into cups, we added the pipe cleaners and set the cups aside.
On the next day the kids poured the water off and examined their crystals! We wrote about the experiment, then bagged everything up for the trip home.
