Floating and Sinking
Grade Level: Fifth

Overview:

Children of all ages are curious about why some objects float while others sink. They have probably had a number of experiences playing in water with a variety of objects. Additionally, they likely have seen air bubbles rising through the water after someone jumps in, or watched boats, leaves, or sticks floating on a pond. Some may have even noticed that they float in the bathtub, yet sink in the ocean.

From such observations and experiences, children have developed ideas and questions about floating and sinking. They may think that weight has something to do with why things float or sink. Others may suspect that size or even the liquid plays a role. The activities in this unit provide experiences on which children can build a more complete understanding of the phenomenon of buoyancy.

  Goals:

-Explore, observe, discover, and describe the variables the   affect the buoyancy of an object
-Observing, recording, and organizing test results
-Communicating observations through writing and   discussion
-Recognizing the importance of repeating a test or   measurement and comparing results
