FIAR: Make Way for Ducklings, day 3

Today was pretty simple, because we belong to a homeschooling group that meets at the park during the summer and at a local gym during the winter for socialization/running around like maniacs time every Thursday afternoon. K gets more than enough exercise on these afternoons for me to consider it a free-form phys ed.

We started the day reading Ducks Don't Get Wet, and then we followed the instructions at the end of the book to prove how ducks stay dry. Actual ducks stay dry because they have an oil gland they use to spread oil over their feathers (this is why you see ducks rubbing their bills over their bodies so much; it's called preening). For our experiment, we spread vegetable oil over a feather:

and then sprayed it and a dry feather with water:


(K insisted on the goggles. It really is just harmless water in the spray bottle). And the water beaded up and rolled off the oily feather while soaking in the dry feather. Pretty nifty.

Tomorrow: some language arts and hopefully geography.
