Science Is Fun: Bowling Balls Float or Sink?

Steal cubes sink, but steal ships float. Lesson explores the density of solids as well as the density of water in determining what will sink and what will float. A hands-on group activity helps pupils see that weight and volume are...

Experiment with mass and density as scholars figure out what makes things float or sink. First, they watch a podcast introducing these concepts. Be sure to use the comprehension question to test their understanding. Young scientists...

For this float or sink worksheet, 8th graders solve 1 science/math puzzle about displacement of water; the answer is available online.

Peer review of science laboratory reports? You bet! First, learners work in pairs to review a scientific article. Then they trade lab reports for peer review. The end result is the publication of a classroom scientific journal!

A homemade video of a physics teacher demonstrating the conservation of energy with a bowling ball pendulum. It is entertaining because he stands against a wall and releases the ball right in front of his face, trusting that because of...

Integrate science and literature by using the scientific method to test the veracity of the floating peach described in Roald Dahl's James and the Giant Peach. Clips from a Bill Nye: The Science Guy episode about buoyancy frontload...

An experiment to determine if either a regular or a diet can of soda will float or sink when placed in water, and what causes this.

In this experiment you learn how to generate carbon dioxide inside a container, and float soap bubbles above the gas. Once the bubbles are suspended, it is possible to observe them closely, which is normally very difficult to do....

An experiment to investigate the thermal properties of rubber by studying its behavior in different scenarios. A discussion of how entropy explains what is observed is provided.

An experiment where static electricity is used to 'bend' a stream of water flowing from a faucet. Includes a detailed explanation of how this works.
