Want to get your students motivated in science class? Given only a piece of aluminum foil, assign groups the task of designing a "barge" that will support the weight of a bunch of pennies.  The group who is able to put the most...

Have your class explore density and buoyancy using this resource. Learners read the book Who Sank the Boat, and use several items, such as rubber balls, bottle caps, wood, and other household items to conduct an experiment. Using a tub...

Have your class predict whether objects will sink or float in water. Learners consider a data table of mass, volume and whether the object sank or floated. They develop an evidence-based explanation for the results.

Students explore physics by conducting a class experiment. In this density instructional activity, students examine a list of items and discuss whether they will sink or float and then determine their density. Students examine the...

This lesson plan is designed to have young children explore the concept of sinking vs. floating by using the skills of prediction, observation and classification.
