Content Videos (Lectures and animations to supplement lessons):
- Composition of Air
- Oxygen
- Reactivity
- Applications
Interactives (Online activities for student interaction & practice with content):
- Interactive Lesson about Air (students learn about the composition of air, proof that air is a mixture, the preparation and properties of Oxygen, and the preparation and properties of Carbon Dioxide)
- Importance of Percent Oxygen in Air (students learn that those creatures that breathe air have come to rely on that air containing about 21 percent Oxygen. If this percentage were to change suddenly, most organisms would have difficulty coping with the new conditions. In this interactive, students slightly increase or decrease the percent of atmospheric Oxygen and see how important not only the presence but the precise amount of oxygen is to life on Earth!)
- Laboratory Preparation of Gases (students review this website to visualize the reactions and lab setups for the preparation of various gases, including Oxygen)
- Fractional Distillation of Liquified Air (students click to see an apparatus guide, animations and video instructions on how to perform a fractional distillation)
- Combustion: The Science of Fire (students learn that combustion makes fireworks explode, matches catch fire, and candles burn. In this interactive, students learn how a fire ignites, how chemical reactions rearrange the molecules of burning material, and what a flame is made of)
- Corrosion/Rusting (students learn that when metals are exposed to the open air and bad weather, they rust. Chemists call rusting corrosion. In this topic we students look at what happens to metal atoms over this time to change them from a “shiny metal” appearance to a dirty, brown powder)
- Properties of Oxygen (webpage reading containing everything a student needs to know about the Element Oxygen; multiple embedded videos to illustrate properties)
- Snowflake Physics (students explore the molecular structure of ice and learn how the typical six-sided shape of snowflakes is due to the arrangement of water molecules in a hexagonal crystal lattice. Discover how snowflakes form and how different conditions affect their growth and morphology)
- Determination of O2 in Air (students read about how to determine percent oxygen in air and view illustrations of the laboratory setup)
- Extraction of metals (students click on bullet #20 to learn about how Oxygen plays a role in the extraction of metals from their ores)
- Animal Respiration (comparison of inhaled and exhaled air)
Games (Online games for students to apply & test their content knowledge):
- Composition of Air
- Atmospheric Chemistry Memory Game (Choose a difficulty level and then click the tiles (squares). Behind each tile is a molecule that plays an important role in the chemistry and composition of Earth’s atmosphere. Each type of molecule is on two tiles. Try to match them all!)
- Atmosphere Quiz
- Gridlocks (Gridlocks are a fun way to learn the facts you need in Chemistry. Unlock the grids to gain entry to the next level and a secure knowledge of the chemistry involved. Based on the ideas behind Su Doku, Gridlocks have a twist that makes them more interesting, more fun, and more useful)
- Gridlocks: Level 1 (11-14s)
- Gridlocks: Level 2 (14-16s)
- Oxygen
- Combustion
