Oxidation And Corrosion

A half-page chart compares the properties of metals and nonmetals. Properties include appearance, melting and boiling point, density, strength, malleability, ductility, heat and electrical conductivity, and the nature of their oxides....

The amount of energy Americans use doubles every 20 years. The first lesson in a 10-part series teaches scholars about different forms of energy. They rotate through five stations with hands-on activities or experiments at each in order...

Fifth graders study the properties of metals and use them to identify different properties.  In this metal properties lesson students complete a demonstration .

After reading an article, "Fuels for Everything," collaborative groups create a concept map poster of the transportation and non-transportation fuels. This makes a strong introduction to the different types of fuels used for transportion...

Demonstrate the aging of materials as you assist the class in creating rust. Individuals demonstrate oxidation-reduction reactions that result in the rusting of materials, differentiate between materials that will and will not rust, and...

Uncover the building blocks of the universe as budding chemists explore atoms and molecules in an exciting inquiry-based activity. Investigators view an interactive video describing the chemical structure of six molecules. Using...

How is iron is extracted from it ore and then combined with other materials to produce steel? That question is answered in the presentation. Also covered is how titanium and aluminum are used in manufacturing. This is a compact lesson...

In the previous video, Sal presented how elements move toward a state of oxidation (by losing electrons), and a state of reduction (by gaining electrons). This lecture takes that concept a bit further, and he provides more examples.

When determining intelligence in animals, scientists use a variety of tests that reveal the animal's ability to use tools, recognize themselves, and communicate. The final video in the Biodiversity series explores why some species, such...

Does a tennis ball have energy? What about a bowling ball? Demonstrate concepts of different forms of energy forms and states with a variety of objects. Using the equations for potential and kinetic energy, learners determine the amount...
