Chemical Reactions in a Safe, Online Environment

BBC Brit's Biggest Bangs is a series of interactive videos that demonstrate how chemicals react with each other. The videos are YouTube videos that take advantage of YouTube's annotations feature.

BBC Brit's Biggest Bangs series starts with an introductory video in which you can choose one of eight chemicals to see how it reacts with another of the eight on the list. The chemicals featured are hydrogen, sodium, sulfur, nitrogen, chlorine, oxygen, iodine, and aluminum. After making chemical selections students are directed to a video that shows what happens when their chosen chemicals are combined. After each reaction video students have the option to return to the start and choose different chemicals.

Applications for Education
While not nearly as engaging as making these reactions in a school lab, BBC Brit's Biggest Bangs is a heck of a lot safer and cheaper way for students to see how chemicals interact with each other. For more virtual chemistry lessons, take a look at these free apps and sites.

H/T to Danny Nicholson for sharing this last week.

A Global Science Experiment - Testing Foods for Vitamin C

The Royal Society of Chemistry has launched a new global project for students. The project, simply called The Global Experiment, asks students to measure the level of vitamin C in fruits and vegetables. The Global Experiment includes a series of small activities for students to complete. The activities are comparing vitamin C content of foods based on where they were grown, the effects of aging on vitamin C levels, and the effects of cooking on vitamin C levels. After completing the activities students can share their results with the The Global Experiment to see the results from other students' experiments around the world.

Applications for Education
The Global Experiment includes detailed directions for teachers and students to use in carrying out each of the activities. Participating in The Global Experiment could be a good way for students to see if location effects the vitamin C content found in various fruits and vegetables around the world.

Slow Motion Chemistry

The Periodic Table of Videos is produced by The University of Nottingham. The table features a video demonstration of the characteristics of each element in the table. Each element in the Periodic Table displayed on the home page is linked to a video.

This afternoon I explored the Periodic Table of Videos YouTube channel and found a playlist titled Slow Motion Chemistry. Slow Motion Chemistry contains ten videos that capture chemical reactions in slow motion. Some of the things that students can see in the Slow Motion Chemistry videos are a hydrogen explosions, muskets firing, and copper sulfate interacting with ammonia.

Applications for Education
As you can see in the video above the Slow Motion Chemistry videos offer more than just slow motion footage of chemical reactions. A short explanation of what is happening is included in each video. That could make Slow Motion Chemistry a good resource to bookmark and share with your students as part of a flipped lesson or to post on a course website as review material.

Chem Collective - Resources to Teach and Learn Chemistry

Chem Collective is a project designed and maintained by Carnegie Mellon University's chemistry department and the National Science Digital Library. On Chem Collective you will find virtual labs for chemistry experiments, simulations, visualizations, tutorials, and auto-graded problems. Students and teachers can search the site by resource type or by chemistry topic.

Applications for Education
Chem Collective offers teachers the option to create their own Chem Collective pages containing resources and activities that they have selected from the Chem Collective library for their students.

What's Inside Coffee? And How Do You Decaffeinate It? - Videos

Earlier today Open Culture shared a video titled What's Actually Inside an Average Cup of Coffee? The video, produced by Wired, gives us a short run-down of the chemical contents of brewed coffee. After watching the video I went looking for related videos on YouTube. I found How Do You Decaffeinate Coffee? published by Brain Stuff. In How Do You Decaffeinate Coffee? viewers again learn about the chemicals in coffee and how how to remove the caffeine from coffee. Both videos are embedded below.

Applications for Education
After watching How Do You Decaffeinate Coffee? I contacted my brother-in-law who is a professor of organic chemistry at Cedarville College and a friend of mine who is a chemist at Boeing to see if this process is something that could be done by high school chemistry students. Both of them think it is.

Learn Chemistry - Videos, Lessons, and an Interactive Periodic Table

Learn Chemistry is a production of the Royal Society of Chemistry. The purpose of Learn Chemistry is provide educators with resources for teaching chemistry lessons to students of all ages. The database of instructional resources has more than 2700 entries organized according to topic, age of students, and media type.

 A couple of resources for middle school and high school lessons that stand out are the Faces of Chemistry video series and the Visual Elements Periodic Table. The Faces of Chemistry is a set of short videos that explain how chemistry is an integral part of three fairly common activities; hair coloring, farming, and car exhaust control. The Face of Chemistry videos are targeted toward students between eleven and fourteen years of age. The first video in the series is embedded below.

The Visual Elements Periodic Table is an interactive display of the Periodic Table of Elements. Click on any element in the table to reveal important information about that element. Many of the element information pages include short videos.

Applications for Education
Whether you teach elementary school, middle school, or high school students, Learn Chemistry seems to have something for everyone. Check out the Learn Chemistry Wiki to see materials developed by other teachers, share your own materials, and find partners for collaborative lessons.

Explore the Chemical Education Digital Library

The Chemical Education Digital Library is a large collection of resources for teaching and learning chemistry. The ChemEd DL contains tutorials for students, 3D models, lesson plans, and more. The tutorials include 3D chemical models and explanations of what each part of the models does and how those parts work together. In the lesson plans section you will find downloadable lesson plans organized by subject. ChemEd DL also features a periodic table that links each element to data and explanations about that element.
