The book, Who Sank the Boat?, is one that I've wanted to buy.
Summary: The reader is invited to guess who causes the boat to sink when five animals of varying sizes decide to go for a row.
Spoiler Alert (as if you can't see this coming!): four huge animals (cow, donkey, sheep, pig) get in, but it's the final passenger, the mouse, that causes the boat to sink.
We did some math and science activities based on the story.
balance scale, you can do a little informal work there as well.
We did some float/sink lessons. (pdfs available--I used the picture drawing one for the 4yo, the writing one for my 8yo) The site also links a BBC interactive video where kids get to predict whether various items will sink or float.
Although this lesson is primarily for my 4yo, my 8yo enjoyed participating in the sink/float scientific inquiry. Challenge question...find an object around the house that will trick mom...one that I think will float when it will actually sink or vice versa. (My son did it with Playmobile animals.)
