This week we continue to spend quality time with gases, more deeply investigating some principles regarding pressure - including John Dalton's Law of Partial Pressures, vapor pressure - and demonstrating the method for collecting...

In this video Paul Andersen shows conceptual thinking in a mini-lesson on proportional relationships. TERMS Quantities - the amount (or number) of a thing Proportional relationship - relation of one dataset to another dataset Directly -...

Mr. Andersen gives a brief description of matter. The five states of matter are also discussed.

In this video Paul Andersen compares and contrasts the properties of solids and liquids. Solids have a more organized structure which can either be amorphous or crystalline. In liquids the intermolecular forces are lower and so the...

This engaging program helps students comprehend the concept of volume. Easy-to-understand examples illustrate how the volume of liquids are measured. Measuring solids is shown using a ruler, or through the process of water displacement.
