Science Skills
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.
Dilution
Accurate dilutions are an important skill for a science student. This clip demonstrates how to use a volumetric pipette and explains how to extend this skill to preparing dilutions.
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.
Personal Safety Equipment
When accidents happen in the science lab, students need to be prepared. This clip demonstrates how to use an eye bath, a chemical shower and a fumehood, and explains the items they can expect to find in a chemical spill kit.
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.
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.
Testing for Organic Compounds
When doing food analysis, a student can test to identify the food component present. This clip demonstrates what to expect when testing for the presence of protein, starch, carbohydrate, glucose, and fats and lipids.
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.
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.
