WonderWorks: Wet vs. Dry
Today's Topic: Wet vs. Dry
Things that DO change drastically (sometimes permanently) in water -- feathers, cornstarch-based packing pellets, tissue paper
Things that do NOT change in water -- coins, paper clips, bouncy balls, painted wooden blocks
Things that change a little bit in water -- popsicle sticks, pompoms, pipe cleaners
buckets or bowls
paper to chart your results on (optional)
The wet dry book / Spohn, Kate
This is a GREAT book for the topic as the pages are alternately matte or shiny to mimic things that are wet or dry.
The inspiration for this class (or "what I thought kids might do"): this was the "Dunk a Pair" project from the Exploring Change chapter of The Preschool Scientist. This book has a lot of great, practical inspiration for a class like WonderWorks or for home explorations.
What the kids actually did:
some kids actually tried putting one of a pair of objects into water and then observing the wet and dry objects side-by-side.
Hindsight Tip: this project miiiiiight be more focused if you had less options of stuff for them to dunk. Also, water projects always work better outdoors in the summer!
