This program introduces the mass spectrometer, the modern method of measuring atomic mass. It uses the analogy of cars of various masses traveling at a fixed speed to illustrate this instrument’s acting principles. (10 minutes)

		The Mole This program introduces the mole as the ultimate "standard container" for directly comparing large numbers of atoms. It also extends the use of the mole to standardize gas volume comparisons, and introduces Avogadro's number.

		Avogadro's Hypothesis This program advances Avogadro's hypothesis that equal volumes of gas at the same temperature and pressure can contain equal numbers of particles. It also examines Avogadro's assertion that each particle of gas can contain no fewer than two atoms and...(more details)		VHS $49.95 DVD $49.95 DVD + 3-Year Streaming $74.93 3-Year Streaming $49.95
		Relative Mass This program looks at how to compare the masses of atoms in order to understand how they differ from one another. The example of two truckloads of pigs and turkeys shows how relative mass can be determined and how the same principle can apply to calc...(more details)		VHS $49.95 DVD $49.95 DVD + 3-Year Streaming $74.93 3-Year Streaming $49.95
		Gas Volumes After looking at the unsuitability of ordinary containers, this program puts forth gas volume as a possible container for measuring the mass of atoms. A concert hall serves as a model for this container, as it has a fixed number of seats, which alway...(more details)		VHS $49.95 DVD $49.95 DVD + 3-Year Streaming $74.93 3-Year Streaming $49.95
		Combining Gas Volumes This program explores what happens when we theorize about how a single-atom particle should behave, using the gas volume hypothesis. It then makes a prediction about the behavior of atoms in gases and compares it to Gay-Lussac's observations for his ...(more details)		VHS $49.95 DVD $49.95 DVD + 3-Year Streaming $74.93 3-Year Streaming $49.95
