Leaves change color and fall from trees. Farmers' crops are fully grown and ready for harvesting. The days grow shorter and cooler. What does it all mean? It must be fall! From changes in plant growth to adjustments in animal behavior (for example, storing food for winter), this colorful book gives kids an exciting opportunity to discover nature in action. Fun activities, such as making a weather notebook to regularly record temperature, cloud cover, and precipitation, help emergent readers participate in a key part of the scientific process. Expertly crafted to meet early elementary reading and science curriculum standards, How Do You Know It's Fall? introduces young readers to science concepts and the two fundamental components of scientific inquiry--making observations, and drawing inferences from those observations.
