What's left of a dinosaur after millions of years? Bones! Dinosaur Bones by Bob Barner is a bright, rhyming book about the bones inside dinosaurs, inside us and inside the museum.

If you're starting dinosaur week with a two-year-old, start here. Dinosaurs, Dinosaurs by Byron Barton is a simple, bold introduction to all kinds of dinosaurs, and it's one of the first dinosaur books many kids fall in love with.

The land is hot and dry. One by one, the animals notice clues that rain is on its way. They smell it, see the lightning, hear the thunder and feel the first drops. When the rain finally comes, everything turns green and the animals enjoy it, until the land slowly dries again.

Animal after animal makes its own sound: cats purr, lions roar, owls hoot, bees buzz and dogs growl. On each page, the children in the book listen. At the end they share what makes people special: we speak!

The book takes each sense in turn: sight, hearing, smell, taste and touch. For each one, it pairs clear photos of everyday things with simple words that describe them, like cold, crunchy, colorful, soft and loud. It encourages kids to notice what's around them and find the words to talk about it.

With a title like that, how could we not start senses week here? I Hear a Pickle (and Smell, See, Touch, and Taste It, Too!) by Rachel Isadora is a bright, funny tour of the five senses through the everyday moments of young children.
