The culminating project for our Light: Observing the Sun, Moon, and Stars was to create a model of a playground that included features that will protect the students from the sun, just like the problem in our story. This project was the students first experience using the Engineering Design Process (located in the front of the STEAM journal). Students tested their designs by placing 5 mystery beads on the playground and then used the flashlights (our model of the sun) to see if the bead would change color. I was very impressed by the teamwork in all of the classes. The kids had a great time creating the playground designs.
