Density
In this video Paul Andersen explains how density measures the compactness of a material. You can calculate the density of a material by measuring the mass and dividing this by the volume. Water displacement is an effective way to measure...

Magnetism: Crash Course Physics
You’re probably familiar with the basics of magnets already: They have a north pole and a south pole. Two of the same pole will repel each other, while opposites attract. Only certain materials, especially those that contain iron, can be...

Gravitational Field Strength
In this video Paul Andersen explains how the gravitational field strength is directly related to the mass of the object and indirectly related to the square of the distance from the center of mass. The equation for gravitational field...

What is Modeling Instruction?
In this video Paul Andersen explains how modeling instruction can be used in the science classroom. Instead of presenting a model for the students the teacher presents and experience or experiment and the students develop the model.

TED-Ed: The paradox at the heart of mathematics: Gödel's Incompleteness Theorem | Marcus du Sautoy
Consider the following sentence: "This statement is false." Is that true? If so, that would make the statement false. But if it's false, then the statement is true. This sentence creates an unsolvable paradox; if it's not true and it's...

The Rate-Limiting Step
In this video Paul Andersen explains why the slowest elementary step in a chemical reaction is the rate-limiting step. This step can be used to determine the overall rate law of the chemical reaction.
