Chemicals can be identified based on their characteristic properties. This is an updated version of my flame tests demo. I got the idea for this demo strangely enough from the AMC television show Breaking Bad. The main character in the show is a chemistry teacher, played by the terrific Bryan Cranston, (he […]

I found a terrific website called the Periodic Table of Videos. Created by the University of Nottingham (yes that fabled town) chemists, the site has videos on 94 of the elements found in the periodic table. They try to demonstrate some of the properties characteristic of each element. Each video is on […]
Molecular Workbench: Chemistry Simulation and Modeling
Published by July 6th, 2008 in Demos, Video and Resources. 0 CommentsI just downloaded, installed and played with Molecular Workbench. It is simulation and modeling software that students and teachers can use to understand what happens in various chemical phenomena. I could see using this on the computer and showing it on the LCD projector to students. At the middle school level you […]
Newton’s third law of motion states that for every action there is an equal and opposite reaction. The video shows one example of Newton’s 3rd law.
Video Demo: Whiteboard Protein Synthesis
Published by May 22nd, 2008 in Demos, Video and Lessons. 0 CommentsProtein synthesis is the process that the cell goes through to make a protein from the information stored in the DNA. The video below shows a demonstration that you can do in your classroom to show how protein synthesis works. This demonstration emphasizes the following points:
1. DNA […]
Lesson: Let’s Grub on Some Grass Beetles
Published by April 14th, 2008 in Demos, Video and Lessons. 0 CommentsLet’s Grub on Some Grass Beetles is a natural selection simulation. Natural selection is the “process by which favorable heritable traits become more common in successive generations of a population of reproducing organisms, and unfavorable heritable traits become less common.” In this activity, part 1 involves variations in silver beak loon beak types. […]
Video Demo: Valentine Chemical Reaction
Published by February 21st, 2008 in Demos and Video. 1 CommentA student of mine gave me an interesting Valentine present. Basically it is a simple chemical reaction in a bag. Watch the video to see how it works. You can buy these a Dollar Tree stores during the holiday season. It was exciting to see how a simple “toy” can be used to teach science!
I’m using a wonderful tool called Voicethread to demonstrate how to extract DNA from raw wheat germ. Click play on how to do the demo and to see how Voicethread can be used. Download the handout for more details.
Video Demo: Yeast Cellular Respiration
Published by February 11th, 2008 in Demos and Video. 0 CommentsThis demo demonstrates that yeast do cellular respiration. When sugar (glucose) and oxygen are present, yeast mitochondria will make those chemicals react and release energy as well as the products water and carbon dioxide. Bromothymol blue solution will change to yellow in the presence of carbon dioxide. If there is no more […]
Lesson: Google Maps/Earth Solar System Scale Model
Published by April 11th, 2007 in Demos, Video and Lessons. 0 CommentsGoogle Maps has recently developed “My Maps” where Google Maps can be annotated with pictures, lines, shapes, and points. I incorporated this new tool with one of my all time favorite lessons: The Solar System Scale Model. This model shows the Sun and the nine planets (yes I still include Pluto for comparison […]
