Humans cannot drink saltwater, but many sea animals need it for their survival. During this Invitation to Create, children used their investigative skills to explore the effects of mixing salt and water. After observing the Inspiration Photo, children experimented with salt, watery paint, and an eyedropper to create their own ocean water scenes. Through this process, children can share and compare their discoveries with peers.
I set up two cups of water, one with salt. They guessed if the egg would sink or float in each cup! We discussed that people and objects float better in salty water.
