What would happen if you had no bones? You might fall over flat on the floor!

Bones are those hard parts of our bodies that make up our skeletons and skulls, and we need them in lots of different ways. In Skulls and Skeletons! With 25 Science Projects for Kids, readers learn about the bones in their bodies and why we can’t live without them. And bones aren’t just good for humans―many animals can’t live without them! But do all animals have bones? No, they don’t! And why do fish look so much different from birds, even though both have bones? Organisms use their bodies in different ways to successfully live in different habitats. For example, a bird’s light bones are great for flying, but would not support them deep in the ocean.

What’s it like outside? Is it a day for building a snowman, constructing a sandcastle, or planting a garden? Weather and Climate!
