Wolves eat better when the bunny population increases, but how long does that last? A series of 12 biology lessons uses the sixth installment to explore the predator-prey relationship between bunny and wolf populations. Young scientists...

Students are introduced to the marine environment of the mussel. The emphasis of the lesson is upon what human factors are present to influence the environment in positive and negative ways. They brainstorm in groups in order to conduct...

High schoolers compile data on population distribution and develop survivorship curves using information from cemetery tombstones and obituaries. They develop inferences on the changes in population age distribution in their area over time.

Pupils answer the question, "What environmental problems arise due to animal and human overpopulation and what might need to be done to combat these problems?" They play games, graph data and write proposals about the question.

Students demonstrate an awareness of the global implications of decisions that individuals and families make about their needs and wants. They identify environmental and health issues related to the production and consumption of food....

Sixth graders investigate the ways in which human beings impact the environment and ecology through the calculation of their own ecological footprint, discussion questions pertaining to biodiversity and potential imbalance hazards, and...

Students discover how plants and animal ecosystems are affected by the growth of a city. In this ecology lesson, students study and observe a plant over a period of time. They develop a creative presentation of their data and share them...

Young scholars explore the basics of ecology. They discuss ecological succession, the water cycle and human impacts on the environment. Students explore the owls, succession, the human impact on the environment and complete the...

Ninth graders are introduced to the concept of population. In groups, they research the problems associated with overpopulation and underpopulation. They practice calculating birth and death rates and discus how they can be used to...

Andree Walker thought of everything when he wrote this resource. It includes a detailed list of materials and background information links for the teacher. In addition, it has procedures, a macroinvertebrate identification key, and tally...

Sixth graders examine the factors that influence the stability of ecosystems. They construct a miniature ecosystem in a jar that includes plants, small fish, and snails, record the population changes over a period of four weeks, and...

Students examine biodiversity and interrelatedness concepts.  In this ecology activity students go on a field trip and fill out a data sheet. 

Students investigate the different hormone contaminants in the water supply. In this math activity, students analyze data tables and graphs. They demonstrate exponential growth and decay using frog populations.

Tenth graders create food web displays in the classroom. In this ecology lesson, 10th graders identify the different pollutants in the environment and their effect on organisms. They collect samples of sediments from the harbor and...

Students explain in their own words why organisms live together. In this biology lesson, students model what happens to organisms if their environment changes. They explain the importance of evolution.

Students study population distribution and survivorship curves by collecting data regarding age of death of humans from either tombstones, newspapers, or other community resources. Students analyze data by creating graphs and population...

A link to a comprehensive macroinvertebrate guide gives you the information needed to prepare for this field study activity. Sample macroinvertebrates are collected from areas representing different environmental conditions. Junior...

Students explore the basics of ecology through numerous hands-on and relevant activities. They participate in an online food chain demonstration, which explores food web dynamics. They dissect owl pellets, examine the prey's bones, and...

Students explore ecology and biodiversty. They use the wet-mount procedure to make several slides to view using the microscope and draw what they see.

Using 2-liter bottles, junior ecologists create composting tubes in which they place nitrogen-rich and carbon-rich materials. They observe what changes occur over two weeks' time. Provide more specific direction to your class as to what...

Students collect data by playing a game that illustrates the delicate ecological balance between fishing, fishing regulations and fish populations. They graph and analyze the data and explain how economic decisions can affect the...

Young scholars observe the changes seen in succession and the biodiversity of a community through its species richness and evenness. They create a dung culture in a clear plastic cup from horse, goat or cow dung then observe the numbers...

Middle schoolers explain the importance of recycling. In this environmental science lesson, students classify materials as recyclable or not. They make posters that promote the benefits of recycling.

How does a population's habitat determine the size of that population? Teach learners about carrying capacity and limiting factors with an engaging roleplay activity. Class members pose as a colony of penguins who must gather food amidst...
