2. Stratus- thick gray paint
3. Cumulus- equal parts shaving cream and glue. It dries fluffy and textured- really fun!
(for cumulonimbus- add a little black paint)
We did this as a go-along activity for Mr. Gumpy's Motorcar and The Cloud Book today in our homeschool co-op. I liked that it worked for our wide age range (3 year olds through six year olds)
