SCIENCE VIDEOS & DVDS

In Chromatography, viewers learn a valuable technique for the rapid separation of chemical mixtures. After the scientific principles of paper chromatography are conveyed through real-life demonstrations and clear graphics, students move into the lab to...

Comparative Anatomy: Dissection uses systematics and anatomy to illustrate the similarities and differences of systems in different organisms. Students learn how advances in medicine have come from the careful study of organs and have an opportunity to...

Cutting and pasting DNA fragments together are among the first techniques learned in the molecular biology lab, and are fundamental to all recombinant DNA work. In DNA Transformation, viewers will become familiar with sterile technique in the lab and...

In Energy & Chemical Reactions, students will investigate and explain how chemical reactions release or absorb energy. The rate of a reaction depends on a number of factors, including temperature, concentration of particles and the presence of...

Lab Safety introduces students to safety guidelines that must be followed when designing and conducting scientific investigations. Lab safety techniques are outlined, as well as the correct use of personal protective equipment. Through a hands-on lab...

In Properties of Gases, students are introduced to kinetic molecular theory and learn about the physical relationships that exist between temperature, pressure, volume and density in gases. Students will see how the gas laws apply to living systems by...

Discover how scientists are able to learn about the world around us by studying how light interacts with matter. Spectrophotometry gives students an understanding of the principles of spectral analysis and explains the relationship between absorbance and...

In The Laws of Motion: Hovercrafts, students will learn how to make and use models to investigate the principles behind the laws of motion. As they test and refine their project, students -- and viewers -- are encouraged to make predictions based on...

Titration allows students to apply scientific concepts to discover what a titration is, how it is performed and how to determine when it is complete. Students see how this technique is applied in a number of real-world settings and become actively...

Water Analysis takes an in-depth look at how scientists test and study water. Viewers follow a group of high school students as they test and compare different water sources for eight factors: temperature, pH, dissolved oxygen, hardness, alkalinity,...

In Earthquakes, students discover how the underground movement of rocks, along with stresses on Earth's crust, produce surface-level tremors. Learn how scientists determine where the hypocenter and epicenter of a quake occur while exploring the...

Fossil fuels were formed millions of years ago as part of a natural process in which the remains of dead plants and animals were buried and placed under extreme pressure and heat. Coal, oil and natural gas are the most important fossil fuels. But what...
