Electrical Safety
In "Electrical Safety", we first look at the dangers of electric shocks by actually demonstrating an electric shock. We then look at the safety features built into our homes and electrical devices that keep us safe from electric shocks.
Galileo's Gift
Nobel Laureate David Politzer describes Galileo’s vital lesson of obtaining knowledge by working with related similar but knowingly inappropriate models that can point towards a deeper understanding.
Changing Cultural Values
Andrew Hoffman, Professor of Sustainable Enterprise at the University of Michigan, discusses how to get people to start being more environmentally sensitive.
What Is Separation?
Mixtures can be separated by methods like sieving, filtering and evaporating.
Using a pH Meter
A pH meter is used to measure the pH of a solution and is a delicate instrument. This clip introduces students to using a pH meter to check the pH of an acid or base.
Using a Microscope
Biology students need to be familiar with how to use a scalpel safely and a microscope correctly. This clip demonstrates how to move about while holding a scalpel, how to use a microscope and how to prepare a dry mount microscope slide.
Titration
Volumetric analysis is an important technique used in quantitative testing, which takes some practice to perfect. This clip demonstrates how to set up and perform a titration using a simple acid-base reaction.
Testing for Gases
Without knowing the equation for a reaction, there are simple tests a student can perform to identify the gas produced. This clip demonstrates the tests used to identify hydrogen gas, oxygen gas and carbon dioxide gas.
Spring Balance, Ticker Timer, Hodson Light Box
All physics students will encounter the spring balance, ticker timer and Hodson light box. This clip introduces these three simple instruments and demonstrates basic skills for measuring force, speed, reflection and refraction.
Separation Techniques
Separating mixtures is an important skill. This clip looks at how to: fan-fold filter paper; separate a mixture of iron filings, sand and sodium chloride; recover a dissolved salt like sodium chloride; and perform suction filtration.
Fire Safety Equipment
When emergencies occur, students need to be prepared. This clip demonstrates how to use a fire blanket, a fire extinguisher and a sand bucket so that students are prepared for a fire in the science lab.
