For the Letter Ww, we did a little experiment with Water, and some plastic bugs with W-wings.
Each preschooler picked a bug from our bug jar, filled up a styrofoam cup with water, and placed their bug into their cup.
Then, we put the cups in the freezer, until the next class day.
We discussed what happens to water when it gets hot, gets cold, or spills out of a cup or the sink.
We talked about ways we could melt our ice and free our bugs.
I introduced the idea of salt to them.
They each ripped their cups off of their ice cube, put their cube in a small bowl, and sprinkled it with salt. They monitored their bugs all morning, watching the salt melt the ice. By the end of class, all of our wings had been freed!
