Paul Andersen explains how a respirometer can be used to measure the respiration rate in peas, germinating peas and the worm. KOH is used to solidify CO2 produced by a respiring organism.

Mr. Andersen walks you through the cellular respiration lab.

Science is about more than just finding immutable laws of nature. It’s about having the imagination to try things and ask questions that might not necessarily lead anywhere, but that just… feel right.

Water is added to dry and bent matchsticks to let us see capillary action at work. The wood absorbs the water causing the matchsticks to straighten. Biology - Plants - Learning Points. Water is a polar molecule because the electrons are...

We use potassium ferricyanide and luminol indicator to show how forensic scientists detect blood at crime scenes. The luminol indicator contains luminol, sodium hydroxide and hydrogen peroxide. When luminol comes into contact with the...

Visual demonstration of the lab factors that affect enzymes

Before we dive into all kinds of fascinating chemistry laboratory techniques, we should familiarize ourselves with all the different equipment we will be using to perform these techniques. The chemistry lab is full of neat-looking...

We are just about ready to do some interesting experiments, but first we need to learn about a very important instrument, pipettes. These are used to transfer specific amounts of liquid from one vessel to another, and there are many...

Learn how to carry out titration experiments. In this video, you will learn what apparatus needs to be used to conduct a titration, including pipettes, burettes and conical flasks. Titration experiments enable us to work out the exact...
