Jessi and Squeaks are thinking of visiting the redwoods, the tallest trees in the world, but there's lots for them to learn before they make their trip! First Grade Next Generation Science Standards Disciplinary Core Idea: LS1.A:...

During the Cretaceous Period, dinosaurs were more diverse, more fierce, and more strange than ever. But something else was happening under the feet of the terrible lizards: for the first time in history, there were flowers.

Some trees lose their leaves in the fall, but some keep their green leaves all year round. Join Jessi and Squeaks to learn about evergreens: where they grow, and how they survive in harsh conditions!

Flowering plants, or more precisely plants whose seeds are enclosed in a fleshy fruit, rather than being naked at pollination.
