Science and Measurement

Searching for a relatively interesting way to demonstrate Charles' Law? Here is a lesson in which pupils heat air inside a flask and then cool the flask to quickly cool the air. They make observations about what occurs during the cooling...

We use basic units of measurement to break down things and communicate clearly. The first instructional activity in an 11-part series teaches the proper way to measure various items. It starts simply with measuring the dimensions and...

Using helium as an example of propane, physical science middle schoolers experiment with and graph the relationship between temperature and volume in gases. In a whole-class demonstration, they show how molecules behave under different...

Ideal for your electricity unit, especially with middle schoolers, this lesson plan gets engineers using multimeters in electrical circuits to explore the relationships among voltage, current, and resistance. Older learners may even plot...

Does mass change during a chemical reaction? Demonstrate the Law of Conservation of Matter while encouraging class members to be creative with a two-part lesson. First, learners use Alka-Seltzer® tablets and water to demonstrate the...

A physical science presentation begins with an explanation of ideal gases and their behavior. Then it introduces all of the gas laws with descriptions and formulas. 

Under pressure to get the class started on the Gas Laws? Look no further! Chemistry scholars learn the basics of the gas laws in a short, animated video. The narrator explains and names each law while working sample problems.

Can you crush a soda can using only the air around you? Use an engaging video to teach about the relationship between pressure, volume, moles, and temperature of a given gas, all done with the Ideal Gas Law.  

A gentle voice and jazz music make this video easy on the senses. It provides a close-up view of a micrometer as the narrator explains how it works and how to use one to measure the diameter of a metal wire. Since a micrometer is used...

A gentle voice and jazz music make this video easy on the senses. It provides a close-up view of a Vernier Ruler as the narrator explains how it works and how to use one to measure the diameter of a pen. Since this ruler is used for...
