Curated OER
Changes in Nature
The goal of this science lesson is to have youngsters be able to identify the physical and chemical changes in the carbon cycle, and water cycle due to weathering. The in-class inquiry/experiment is quite interesting and easy to...
Curated OER
Environmental Changes
High school scientists reasearch and illustrate changes in the local environment and consider relationships among agriculture, industry, economy, natural events, and social interactions. They construct a timeline to discover if there are...
Curated OER
Environmental Changes from Space
Students discuss Landsat Satellites and the use of the images they provide as well as the purpose of keeping records of the information from the satellites. The class works in groups to complete a worksheet on short term and long term...
Curated OER
Leaf Stomata as Bioindicators of Environmental Change
High schoolers perform an experiment to determine the stomaltal index on the upper and lower epidermis of two species of leaves. Stomatal densities change in response to changing atmospheric levels of carbon dioxide and to annual rainfall.
Curated OER
Changes in Attitude about the Role of Woodlands
Pupils investigate the historical forest cover in the United States in 1873. They study a map of 1873 and analyze changes in attitudes about the environment that have taken place in the United States.
Curated OER
Impact of Exotic Species in an Environment
Students explain the impact of exotic species in an environment. In this non-native species lesson students construct posters and dioramas showing environments before and after the invasion by an exotic(s).
Curated OER
pH Potential
Students experiment to determine the positive and negative impacts of human activities on environmental change. They examine how physical and biological processes such as decomposition affect soil characteristics while looking at the pH...
