This activity has two purposes: challenge the learner to develop a procedure for investigating a research question and to learn more about factors affecting the dynamics of air in motion. It demonstrates that warm air and cold air differ in weight... (View More) and this difference affects air's vertical movement in the atmospheric column. Resources provided to students for this challenge include a homemade balance beam made of wood, two paper bags, a desk lamp, paper clips, tape and a thermometer. The resource includes background information, teaching tips and questions to guide student discussion. This is the chapter 8 of Meteorology: An Educator's Resource for Inquiry-Based Learning for Grades 5-9. The guide includes a discussion of learning science, the use of inquiry in the classroom, instructions for making simple weather instruments, and more than 20 weather investigations ranging from teacher-centered to guided and open inquiry investigations.

Highly productive commercial agriculture, known as industrial agriculture, is the focus of this investigation. Students will analyze and compare the inputs and outputs of industrial agriculture after reading background information, examining photos... (View More) and satellite images, graphing data, and answering questions. The role of technology in shaping industrial agriculture is also examined. Suggestions are offered for optionally assessing this lesson in a debate format or in a role-play format.

This is Investigation 2 of three found in the Grades 9-12 Module 2 of Mission Geography. The Mission Geography curriculum integrates data and images from NASA missions with the National Geography Standards. Each of the three investigations in Module 2, while related, can be done independently. (View Less)

The Aral Sea, located between Kazakhstan and Uzbekistan, is diminishing in size. Students must analyze and interpret the background information, photos, images and data provided in order to determine the causes of the size change as well as the...

Students confront the challenge of improving global agricultural production in order to feed increasingly larger populations. Students evaluate tables, maps, graphs, photos and satellite images detailing global population growth patterns and... (View More) agricultural production levels in order to formulate recommendations. The role of technology is examined throughout. This investigation includes two activities: 1. Students form six teams representing major world regions to consider the need for increasing agricultural production; 2. Students conduct a case study of Mozambique and conclude by distributing and defending monetary investments for possible agricultural production increases.

Subsistence agriculture is introduced and described through text, satellite images, space shuttle photos, ground photos and maps. After reviewing all resources, student teams debate whether intensive subsistence agriculture (e.g., rice production)...
