In this part of the unit, students are exploring how global temperatures have changed over the past hundred years. Students will examine tables and graphs about global temperatures and carbon dioxide levels, human consumption of food, and human consumption of natural resources. They will find patterns in the graphs. Based on this data, students will construct an argument about how human activities (increase in population and consumption of natural resources) cause global temperatures to increase.
In this lesson, the Internet is used as a resource for students to access daily (and hourly) information about air quality.
In this lesson, students explore the role of regulations in influencing air quality decisions as they examine trends in air pollution. The students are encouraged to think
critically about important technological developments that have influenced the lives of individuals since the start of the twentieth century.
CK-12 Earth Science For Middle School covers the study of Earth - its minerals and energy resources, processes inside and on its surface, its past, water, weather and climate, the environment and human actions, and astronomy.
Species extinction is happening at an alarming rate according to scientists. In this lesson, students are asked to consider why extinction is a problem that we should concern us. They are taught that destruction of habitat is the main reason many species are threatened. The lesson explores ways that engineers can help save endangered species.
This lesson will discuss the details for a possible future manned mission to Mars. The human risks are discussed and evaluated to minimize danger to astronauts. A specialized launch schedule is provided and the different professions of the crew are discussed. Once on the surface, the crew's activities and living area will be covered, as well as how they will make enough fuel to make it off the Red Planet and return home.
Students take on the challenge to educate the community about Earth’s climate system. Students learn about Earth’s greenhouse atmosphere, causes and impacts of natural climate changes in the past, identify human activities that are responsible for causing current climate change, and what actions communities can take to mitigate the effects of global climate change.
This computer-based learning module engages students in questions that scientists around the world are exploring about Earths climate. They gain an appreciation for how much is not known about the Earth and climate change. The module contains 5 activities; 1) Earths Changing Climates, 2) Interactions Within the Atmosphere, 3) Sources, Sinks, and Feedbacks, 4) Feedbacks of Ice and Clouds, and 5) Using Models to Make Predictions. Each activity provides information in simulations, text, video, or graphic format and the students enter answers to both open-ended and closed questions within the program. Once the students have completed an activity, they can print a report showing all the questions and their answers. The authors estimate the entire module should take 225 minutes.
