The Modern Atmospheric CO2 Record

In this atmospheric carbon dioxide worksheet, students use two diagrams to solve 6 problems about atmospheric carbon dioxide. One diagram shows the Keeling Curve and the other shows sources of carbon and the natural and anthropogenic...

Students examine the effects of carbon dioxide on the environment. In groups, they research the the usefulness of emissions testing in the state of Florida. To end the lesson, they discuss the impact of an increase in greenhouse gases...

In this gases worksheet, students conduct an experiment to produce 2 different gases and use standard tests to identify each gas. This worksheet has 14 short answer questions.

Trying to plan a lesson on the respiratory system? Then take a deep breath, because this presentation has you covered. From the atmosphere through the lungs and blood to the body's cells, this presentation investigates the complex series...

Can you imagine Washington DC and London as close neighbors occupying the same continent? Learners will be fascinated as they step back in time and discover the evolution of the earth's continents and oceans from 4.5 billion years ago to...

Have you ever seen solid nitrogen? Or solid carbon dioxide? Watch as a pair of instructors adjust pressure to allow liquid nitrogen to solidify. After they finish, they put the solid nitrogen in water which produces carbon dioxide gas...

Students work in groups, plotting carbon dioxide concentrations over time on overheads and estimating the rate of change over five years. Stacked together, the overheads for the whole class show an increase on carbon dioxide over five...

Students examine CO2 atmospheric levels. In this atmospheric lesson, students examine the correlation between CO2 levels and global warming.

The use of fossil fuels is contributing to the amount of carbon dioxide in the atmosphere. If we can produce fuels using cellulose-based ethanol, we may be able to remove carbon dioxide in the atmosphere. Scientists are searching for a...

When was the last time your class saw a catalyst in action? Chemistry scholars observe an activated complex during an engaging experiment. Through both color change and evolution of a gas, individuals gain insight into the...
