Precipitation reactions are always interesting. How about one that forms a precipitate using a gas? Chemists of any age will enjoy this twist on a standard solubility lab. Partners observe the lack of interaction between sodium...

Where does the pop in pop rocks come from? An engaging activity asks scholars to measure the amount of carbon dioxide in a package of Pop Rocks candy. Learners dissolve the candy in water and use the solubility of CO2 to determine its mass.

In this atmospheric carbon dioxide worksheet, students use a graph of the Keeling Curve showing the increase in atmospheric carbon dioxide since 1958 to solve 6 problems. They determine the rate of increase, the find the percentage of...

In this atmospheric carbon dioxide worksheet, learners 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...

In this atmospheric carbon dioxide instructional activity, students observe a map showing the concentrations of atmospheric carbon dioxide taken by the Atmospheric Infrared Sounder instrument. Students solve 4 problems using the map....

In this carbon cycle instructional activity, students will read about the carbon cycle and study a diagram showing what creates carbon dioxide and what uses carbon dioxide. Students will then complete 4 short answer questions.

How much does your class know about the relationship between climate change and carbon dioxide? Science scholars explore the nature of greenhouse gases and rising ocean temperature through demonstrations, research, and experiments. The...

It is recommended that you conduct this fabulous experiment as a whole-class demonstration. Collect air samples from the environment, human exhalation, and car exhaust, then compare them for carbon dioxide content using bromthymol blue...

Provide your class with the opportunity to view our carbon cycle close up. Young scientists research the cycle of oxygen as it completes the tasks of photosynthesis and respiration. They explore the importance of carbon in an ecosystem...

In this carbon worksheet, students follow directions and use marshmallows and toothpicks to made carbon dioxide and glucose molecules. Students do this to see how carbon changes as a result of photosynthesis.

In this emissions worksheet, students will study a graph comparing biological and industrial carbon dioxide emissions over the years and another graph showing the geographic regions of carbon dioxide emissions. Using this information,...

Emerging ecologists need a full understanding of life, from the inner workings of a cell to the complex relationships among organisms. This examination is meant to assess high schoolers after an entire year of courses on the living...

The New York Regents High School Examinations are comprehensive and include various question formats, including multiple choice and graph analysis. This particular version, the 2008 Living Environment exam, surveys a variety of topics....

Environmental science enthusiasts show what they know at the end of the year by taking this full-fledged final exam. They answer multiple-choice, graph interpretation, and essay-analysis questions, 73 of them in all. Topics range from...

The 2005 version of the Regents High School Examination in ecology is as comprehensive as previous years' exams. It consists of 40 multiple-choice questions on topics ranging from the structure of DNA to interactions within an ecosystem....

The living environment, from the interior of a cell to the complex relationships among populations, is queried in this final examination. Learners examine air pollution maps, cell diagrams, population graphs, and drawings of cells. They...

Young scientists discover that air is a mixture of different gases - mainly nitrogen and oxygen. The properties of some of the other gases found in oxygen are listed in a table, then learners must decide which one of those gases is...

When you need a review instructional activity for your AP biologists on water and nutrient transport in plants, this one is for you! From the simple stuctures involved to the complex mechanisms that make it happen, the details of...

For this atmosphere instructional activity, students read a data table showing the percentages of carbon dioxide, oxygen, and nitrogen in the atmosphere over the last 4500 million years. They then create a graph comparing these gases...

For this thermal decomposition of calcium carbonate learning exercise, students perform three experiments on calcium carbonate, make observations, and write the equations for each reaction. Students explain in detail what happened at...

In this chemistry worksheet, young scholars identify how many liters of oxygen can be consumed to form carbon dioxide. Then they identify how many liters of sulfur dioxide are produced if the gas is at STP.

In this chemistry worksheet, learners write the balanced equation for the problem at the top of the sheet. Then they determine which reactant is the limiting reactant and which one is in excess. Students also explain the procedures for...

For this modeling the Keeling Curve worksheet, learners use given data beginning in 1960 to create a mathematical model for the changes in atmospheric carbon dioxide over time. Students manipulate the equation to predict the carbon...

In this energy consumption worksheet, students use on line resources to explore the energy use by different countries around the world. Students compare the amount of light emitted by different countries and their carbon dioxide...
