This activity is a student based inquiry looking at various natural disasters and their impact.

In 1958, black bass were introduced into Lake Atitlan in the highlands of western Guatemala as a way to attract tourism and boost the local economy, but unforeseen complications resulted in an ecological disaster. Developed for an introductory course in biology, this case study first casts students in the role of the local population at that time and asks them to judge the proposal to introduce the new species of fish. The students then review the ensuing events from a historical perspective based on additional information they receive from the instructor in a progressive disclosure format.

This activity is a classroom investigation where students predict, explore and evaluate what happens to water as it travels through the water cycle.

By presenting the students with fossils and other earth materials and giving clues as to their origin, they will be able to identify the fossils and materials and be able to form a hypothesis as to how they were formed and what it was before preservation.

Students will create and investigate testable questions about how basil changes based on growing conditions.

This field activity asks students to examine and interpret a given environmental site where a disturbance (fallen tree, beaver dam etc.) has taken place.

Designed for use with small groups in an introductory geology class, this case allows students to determine the relationship between sinkhole development in a karst terrain and groundwater levels. Students then apply this knowledge to a lawsuit filed by the family of a driver of a minivan who dies after his car plunges into a sinkhole allegedly caused by a mining company.

This activity is a field investigation where students will learn the importance of detail when nature journaling.

This activity is a project in which students research keystone species and report on specific species to the class.

This activity is a classroom chemistry lab where students will test different cleaning methods that could be used in oil spills. They will see the effects how oil spills damage animals and the environment.

This activity is a field investigation where students will observe, discuss, and gather evidence on how environmental changes affect animals that live in that habitat.

This activity is a reinforcement lab activity where students experiment with ways to get water to flow out of a cup and up a straw causing an imbalance in the atmospheric pressure surrounding the water.

In this field lab students will investigate the biodiversity around their school. Students will perform a biodiversity count using transect line. The students will develop multiple hypotheses relating to biodiversity and propose additional procedures for studying, collecting and testing these questions.

This plan involves observing and labeling clouds and conducting an experiment on how clouds form.

This activity is a field investigation where student create a life-sized contour map and discuss why some contour lines are different from others.

Students observe the decomposition of a pumpkin under controlled circumstances. These observations are used to take notes and develop questions.

In this classroom activity students will learn about changes that occur in the earth's surface by investigating the process of weathering and erosion. Through interactive lectures and experiments students will understand how weathering and erosion take place and change the earth.

This activity is a field collection investigation where students gather earth materials and make observations about their collection that leads them to discuss the nature of Earth surface and how it is changing.

This activity is an indoor lab where students build a model to observe the effects of weathering and erosion.
