Pupils investigate the relationship between dissolved oxygen and organic materials and aquatic organisms. This is a 3-activity series in which students explore dissolved oxygen and then design an experiment testing the effects of changes.

Fourth graders research the Rendezvous. They then set up bartering stations for students from other classes to visit.

Learners explore the relationship between greenhouse gases and global warming. Carbon dioxide is studied as a contributor to the problem.

Learners examine and participate in an inquiry process. They brainstorm recall, comprehension, and synthesis questions for a research topic, and write the questions on sentence strips.

Students are shown an experiment making ice cream while discovering the freezing point depression. There are questions for students to answer after the demostration.

Students examine a color-coded map of U.S. acid rain precipitation intensity. Using EPA data table and the blank U.S. map, they record state-by-state values for magnitude of emissions and compare areas of emissions to areas with the most...

Students create their own sling psychrometer to measure relative humidity. They work together in groups to make and use the psychrometer. They are asked questions about their experiment to complete the lesson.

Students examine the different types of clouds and how they form. They are to create their own weather forecast based on their observations of clouds in their area. Questions are asked for comprehension to end the lesson.

Students draw hands from life. They combine realistic hand drawing in fantasy "scape". They utilize elements of design demonstrating composition and value shading.

Students define and associate words with the topic of climate change while completing associated worksheets. They read and discuss articles about climate change including the effects of global warming and the greenhouse effect.

Students complete an experiment to determine how dirty the air is in their local community. They analyze images and discuss the varying degrees of air pollution. They discuss the results of the experiment.

Fourth graders work together to complete an experiment on air pollution. They identify visible and invisible forms of pollution. They gather their data in notebooks and analyze their results to end the lesson.

Students perform a play that presents the causes and effects on people and the environment of the eight major air pollutants.

Middle schoolers investigate local surface weather conditions. They log weather conditions for thirty days, develop a graph, plot cloud cover, and compare/contrast the graphed lines of various weather factors.

Students explore the respiration rate of a mealworm. Through experimental means, they determine the average volume of oxygen used and discuss factors that affect the respiration rate of an organism.

Seventh graders read "Diary of a Young Girl" by Anne Frank. In groups, they discuss the reasons why people would write an autobiography and identify their own identity crisis. After reading excerpts of other autobiographies, they...

Students study the social class conflicts that existed during the Russian Revolution by reading the short stories of Anton Chekov and Leo Tolstoy. They analyze the stories to find criticisms of pre-Revolutionary Russia before designing...

Students investigate different factors that affect plant growth. They research the effects of water supply, radiant energy, air temperature, and soil temperature. Students also gather facts that influence plant nutrition that include the...

Students investigate the factors that compose the nitrogen cycle. The harmful effects of acid rain and ozone depletion are also discussed in the lesson. Students define the nutrient that is often limiting to plant growth through...

Young scholars explore the challenges of living in space by designing a facility that can provide everything required to support humans and can protect them from the harsh environment of space.

Students brainstorm the factors affecting the speed at which a space capsule reaches the surface of a planet or moon and suggest how engineers might deal with each factor. They then create a model which is dropped from a high point...

Students investigate the concept of a carpool and its contributions to either reducing or increasing air pollution. They conduct research using a variety of resources for background information. The information is used to write a play...

Students explore about the One-Tonne Challenge, and work out how they could reduce their greenhouse gas emissions (GHGs) by one tonne, through individual actions and by influencing other people. Students use a GHG emission table to...

Students explore the importance of agriculture, especially tobacco farming, and the influence it had on slavery in the state of Virginia. Students establish the sequence of tobacco and slavery in the state.
