How to Make a Miniature Volcano
Making a miniature volcano is simple by mixing in a small container baking soda, a bit of dish soap and vinegar that has been dyed red. See this volcanic chemical reaction with a demonstration from a science teacher in this video. Run time 02:05.
Process Of Burning a Diamond
Describes the periodic law in terms of the reaction of certain elements. Demonstrates that even diamond can react and form a gas. Video shows the burning of the diamond and explains why Mendelev placed both silicon and carbon in the same group. Grades 7-12. Includes closed captioning. 2:46 min.
The Oxidation States of Uranium
Shows the oxidizing of uranium, and the reaction of uranium 4 with nitric acid. Video clearly shows changes to the the uranium in the reactions. Grades 7-12. Includes closed captioning. 1:08 min.
The Law of Action and Reaction: Newton's Third Law
The Law of Action and Reaction: Newton's Third Law This NASA video segment explores how Newton's third law of motion applies to aerospace.
Where Do You Get Your Energy
Cells extract energy from sugar to produce ATP, the molecular fuel that powers all life processes. This interactive activity adapted from the Exploratorium delves into the processes that enable cells to unlock the energy contained in the foods we consume. We often use the term "energy" as an informal shorthand for our ability to stay alert and complete tasks. In fact, the presence of energy-rich molecules and our cells' ability to obtain, process, and use this energy is critical to life.
On the Surface Surface science examines how surfaces react with each other at the molecular level. The atoms at the surface are different than those atoms in the center of an object, making the atoms much more reactive than those inside. This program explores a variety of real world applications of this particular property.

How to Make Foam Science Experiment
In this video kids can learn a fun and easy science experiment. Watch as they show you how to make foam. The experiment uses vinegar and baking soda and is an example of a chemical reaction. Run time 01:09.
Really Foamy Reaction
Elephant toothpaste is the name given to the catalyzed decomposition
reaction of 30% hydrogen peroxide that uses soap to collect the oxgen
gas that is produced. It is a favorite of most students at chemistry
Molecular Visualizations of DNA
Amazing CGI visualization of molecular biology's central dogma. It shows animations of DNA coiling, replication, transcription and translation.
This short video uses color animation and narration to explain how mutation occurs at the molecular level. 1:19 min.
Landing on the Moon--July 20, 1969
NASA footage with international broadcasters showing public reaction to the landing on the moon. Run time 09:54.
Signals From Within Chemists' knowledge of the interaction of radiation and matter is the basis for analytical methods of sensitivity and specificity. Scientists can determine the structure of a molecule by various means, including molecular probes such as radiation. Spectroscopy allows scientists to analyze matter.

HX to Alkene Reaction
Video discusses the first two electrophilic addition reactions. The first one is addition of HX to an alkene. The second one is hydration reaction. Each one of these is explained.
Halogen Addition Reaction
Let's take a closer look at the Halogen Addition Reaction. Video discusses vocabulary such as, halogen, solvent, non-reactive solvent, and how to add the halogens.
Opposition to the Treaty of Versailles in the USA
President Woodrow Wilson felt optimistic about returning to America with the completed Treaty of Versailles. His return, however, was marked with a mixed reaction from the public and the Congress. Initially, Republican Senator Henry Cabot Lodge, who had ardently opposed the treaty, had little hope of defeating it in the Senate. Instead, Lodge and other Republican Senators hoped to amend the treaty, so that they could take credit for the changes. These individuals were known as “reservationists
1968 King Assassination Report
Walter Cronkite had almost finished broadcasting the "CBS Evening News" when he received word of Martin Luther King's assassination. His report detailed the shooting and the nation's reaction to the tragedy. (CBSNews.com)
The Nature of Water
This video is accompanied by text: "A key theme in biology is the relationship between structure and function. In order to appreciate the chemical and physical properties of water, we need to understand its molecular structure.
The chemical formula of water is H-2-O, meaning that each molecule of water contains two hydrogen atoms and one oxygen atom. Each hydrogen atom is connected to the oxygen atom with a covalent bond..."
Organic Chemistry: Haloalkane Synthesis
This video describes reaction between tetrahydrofuran and excess HBr. Bromine itself is a very large atom and it spreads the negative charge over that large area which pushes the hydrogen further away from it, making it more vulnerable to attack. Tetrahydrofuran is a very reactive molecule because you are forcing the oxygen into a crowded position with electrons. Those electrons are going to be looking to jump off onto anything they can to go into a lower energy state... Run time 01:44.
Introduction to Newton's Three Laws - Lesson 1
This NASA video segment explores how Newton's Laws of Motion apply to the development and operation of airplanes. Viewers watch an instructor at NASA's National Test Pilot School as he describes and then demonstrates why seatbelts are an important force on pilots; what it means to pull 2, 4 and even 6 g in a jet; and how the thrust of a jet engine causes an aircraft to move forward. Formulas are presented onscreen along with the calculations discussed in the segment. For example, the instructor
5.2 Wilberforce’s anti-slavery campaign in context
William Wilberforce, the politician and religious writer, was instrumental in the abolition of slavery in Britain in 1807. This unit explores Wilberforce’s career and writings and assesses their historical significance. In particular it examines the contribution that Evangelicalism, the religious tradition to which Wilberforce belonged, made in the transitions between the Enlightenment and Romanticism. Throughout it relates Wilberforce’s career and writings to wider social and cultural devel
