The sustainability of an ecosystem depends on many factors and changes constantly. Young scholars consider these factors as they use a set of cards to create food webs. They review key scientific vocabulary such as predator, prey,...

Areas that previously included no risk of Lyme disease now have cases every year. Scholars learn about the spread of Lyme disease and the relationship with ecological succession. Then, they discuss possible solutions using the known food...

In the ecological game of who eats who, one small change can have a big impact! Individuals create food chains in an array of ecosystems, then determine what happens to organisms in the chain when one organism changes its feeding...

Looking for a fresh take on traditional food/energy pyramids? Conduct an innovative activity where pupils build their own! The lesson uses research data from Gorongosa National Park in Mozambique for a real-life safari touch. Scholars...

Diversity in a biome leads to some unique characteristics vital to the natural environment. Young scholars use an interactive map to explore the vegetation and climate of the Gorongosa National Park. They collect climate data to compare...

Producers, herbivores, carnivores, omnivores, decomposers. To begin a study of the forest ecosystem, learners examine the connections among the members of ecological communities.

It's a jungle out there! Young biologists journey to Darien, Panama to examine the intricate relationships between the organisms that inhabit the jungle. Groups begin by demonstrating an understanding of energy flow in ecosystems, then...

Investigate desert biomes by creating food chains and food webs. Groups first research feeding habits of organisms in the Sonoran Desert. This information helps pupils draw food chains and webs to determine relationship between organisms.

In a fun and interactive two-day lesson, learners sort anole lizard pictures by appearance. Next, they watch a video about the anoles and re-sort based on the information in the video. In addition to physical characteristics, budding...

In this lesson, students learn about different types of ecological relationships, including symbiosis, mutualism, commensalism, and parasitism. Includes handouts and a vocabulary list with definitions.

This activity is designed to accompany an interactive on the Annenberg Learner website. Students investigate the changes that take place in an ecosystem when they alter the organisms in a food web. As they work with the simulation, they...

Discuss how individual organisms and groups of organisms interact with each other, and research and classify symbiotic relationships between individual organisms of different species.

Being field scientists, students will explore a wooded area in their community and journal about their observations. Students will collect information about producers, consumers, and decomposers in the ecosystem. They will then construct...

In this activity, students create a "web" to identify and demonstrate the interactions among the living and non-living parts of an environment. This information allows students to better understand what an environment is and to also...
