Buoyancy

Today in class we finished up the "will it float or sink?" activity.

Similarities for the objects that floated were: all are roundish, all are hollow or have pockets of air in them, and all objects are soft.

Similarities for the objects that sank were: all are made of metal, all are solid

Homework:
Read pg 130-133 in the Science Textbook. Write 4-5 sentences on "What is density?"
