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...

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 obtain remote sensing data to compare and contrast global biomass data with global temperature data.

Life has its ups and downs ... especially if you're an animal! Biology scholars engage in a population study through an inquiry-based lesson. Pupils work together to explore the factors that affect deer populations, then examine the...

Seventh graders create a model of an ecosystem and label it to show structure and function. They research the food web of an aquatic animal and also trace energy flow from the primary producer up the food chain.

The "Bottled Bacteria" activity instructions are a bit unclear, but the remaining activities investigating limiting factors in ecosystems are well-written. Learners model the exosystem of a bear and a herd of deer. They set up a...

Examine predator-prey marine relationships through an interactive lesson design. Learners begin by studying a specific shark species and then analyze real-time shark-tracking data. They also study threats to shark populations and...

Tenth graders conduct various activities utilizing the scientific method to formulate a hypothesis, conduct a controlled experiment, collect and analyze the data and communicate their results through a poster. They also identify...

Students research plants and examine populations in ecosystems.

It's the attack of the invasive species! Young scientists simulate the behavior of an invasive species with a game-like activity. They assume the roles of native plants, invasive plants, and resources and watch the invasive plant takes...

Students observe populations and determine the functions (e.g., decomposers, producers, consumers) they serve in an ecosystem. They investigate the energy flow ecosystems. Students investigate factors (.g., Resources, light, water) that...

Here is a hard-hitting, cross-curricular instructional activity on the effects that the deforestation of the Ozark forests in the 19th century had on the people, animals, and ecosystems of the area. The Dr. Seuss book The Lorax is used...

Young scholars construct a defined plot on school grounds and observed patterns in plant life. They count trees, shrubs, cacti and record on a data sheet. They compare data and generate a plant diversity overlook for their school.

Ninth graders conduct an environmental inventory on one ecosystem. They collect data, and write an environmental impact statement on that area. Students explain the interactions between different systems found within an ecosystem....

Fifth graders define vocabulary terms, identify the characteristics of a pillbug, and create a dichotomous key. Then they examine the pillbugs and make observations and record these observations. Finally, 5th graders observe specific...

Fourth graders experiment to determine how overpopulation effects ecosystems specifically plants. In this ecosystem lesson, 4th graders conduct an ecosystems experiment after listening to Claire Daniel's, Ecosystems. They watch a video,...

Learners explain why dissolved oxygen is important in aquatic ecosystems. They evaluate the optimal dissolved oxygen levels for living organisms.

Young scholars investigate plants and compare them to the purple loose strife. As they observe the plants they predict possible impacts on plant populations based on their observations. They work in groups and present their findings to...

A balanced ecosystem doesn't mean balanced populations. Budding scientists complete a series of activities to learn about the relationship between producers and consumers in an ecosystem. They complete the wildlife conservation...

Students practice techniques of field observation and data-gathering while studying local bird population, describe ecosystem as complex combination of elements, which can affect or be affected by each other, and determine effects of...

Students investigate marine life by researching aquatic organisms on the Internet. For this oceanography lesson, students monitor algae and animals of the ocean by identifying their population and habitat on data sheet ID cards. Students...

Students define population and carrying. In this algebra lesson, students explore exponential growth and decay based on animals and things that grow or decrease exponentially. They graph their findings and discuss their results as they...

Students explore Earth's biosphere. In this biosphere lesson, students participate in group activities regarding biotic and abiotic factors, population density, and species' habitats.

Strict habitat requirements are needed for the survival of fish populations and fish variety in the Great Lakes. Young scientists become experts in the basic needs of fish and understand how survival necessities can vary with different...
