Crystal Hearts Investigation
The investigation can be found in my Valentine Science set. It includes all the directions, student recording sheets, science explanation sheets, and anchor chart photos to help make the process more visual and concrete for the children.
A Gift from the Science Lab
We think these sweet hearts make great Valentine gifts for the children to take home to their families. They also look really pretty hanging in front of a sunny window, so consider getting some ribbon and displaying them for a little added sparkle in your classroom!
Before You Toss the Trash
In the lesson, I recommend NOT throwing away the cups after the hearts are removed the next day. Crystals will form on the sides of the cup, too. Teach the children to be delicate when handling their crystal hearts, but the leftover materials in the cup are perfect for further hands-on exploration. I like to let the kids hold them, rub them, and press them to see how they feel, smell, look, and sound.
