Anemones contain harpoon-like structures in their tentacles to attack prey. A video shares an up-close look at an anemone eating a goby. It highlights the attack, capture, and demise of the prey through a system evolved over the course...

Flatworms evolved and developed the first bilateral body plan. These hermaphroditic animals with no circulatory system star in an informative video. Scholars learn about flatworms' place in the evolutionary tree, how they hunted, and...

While most sea anemones move slowly along rocks, Stomphia swim to escape predators. Viewers see a sea star sneak up on an anemone ready to attack. The unsuspecting anemone retaliates quickly and swims away awkwardly as part of a larger...

45 percent of all raptors migrate, but they don't follow the paths of other migrating birds. An extensive Seasonal Science series introduces the unique migration process of raptors. The narrator explains the extremely small migration...

Beat the heat using sensors. Scholars research normal body temperatures for humans and a specific animal. In groups, they create sensors that monitor body temperature, as well as the weather. The goal is to reduce the occurrence of heat...

Human impacts on the environment can sometimes be difficult to measure, especially under water! An activity centered on ocean acidification gives science scholars the opportunity to examine the effects of carbon dioxide on marine life....

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...

Breathe some life into product design. Pupils learn about the stages of product creation, use, and disposal—sometimes called a cradle-to-grave assessment. They see how this cycle relates to the life cycle of organisms.

Produce, consume, decompose...repeat! Examine how matter and energy cycles in ecosystems by watching a video discussing NGSS standard LS2B. The narrator explains the requirements of the standard at each grade level, plus gives tips to...

Scientific models help explain ideas and concepts to non-experts. The online activity covers conceptual, mathematical, and physical models. Through four multiple-choice questions and three discussion questions, scholars gain a deeper...

This is one super model interactive! Middle and high school science scholars examine scientific models through a simple resource. Guided, hands-on practice allows them to classify conceptual, mathematical, and physical models. Other...

Small but mighty! Learners explore the role of microbes in a healthy ecosystem. An engaging lesson asks pupils to design an aquaponics system that demonstrates that healthy microbes are necessary to maintain the ecosystem.

Get a little dirty as your classes explore the aspects of healthy soil. Scholars learn that healthy soil has a different meaning for a farmer, a consumer, and an environmentalist. They also experiment with different soil types to analyze...

Examine the impact the fishing industry has on local ecosystems. The hands-on lesson begins with an experiment that tests the effectiveness of fish-based fertilizers. It continues with a computer-based module that simulates sustainable...

Can you name the biological interactions you encounter during a day? Your classes might be surprised by the number of interactions they experience! A comprehensive lesson plan explores the science of symbiotic relationships. Learners...

Global warming isn't just an issue on land; deep ocean waters are also showing troubling signs. Young scientists learn more about deep water corals and the many recent discoveries researchers have made. Then they examine data related to...

Hold the sea in the palm of your hand! Amateur oceanographers work together to create models of an ocean ecosystem in the sixth and final installment in a series. Raise awareness of global ocean health issues through guided research,...

When the sun's rays can't reach the producers in a food web, where does all the energy come from? Extreme environments call for extreme food sources. Young scientists investigate creatures that appear to get their energy from methane...

A hands-on activity helps learners explore the water cycle. After discussing how they use water, classes discuss water pollution and then move into a simulation where 20 pupils move through the water cycle based on description cards. 

Learners examines the arctic food web with a short video about polar bears and an article about bears and warming temperatures. They design an arctic food web and discuss the trophic cascade that could come from climate change. 

A food web has no organism higher than a tertiary consumer because there wouldn't be enough energy left to sustain them. The fourth installment in a seven-part series begins with a nature walk to get pupils thinking about their...

Some organisms spend their entire lives in leaf litter. The third in a series of six is a great lesson plan exploring the community of leaf litter. Groups gather and then spread leaf litter over white paper and remove leaves/twigs while...

Dead trees provide nutrients for the soil, food for animals, protection and a home for organisms, a seed-bed for new trees, and a place for nitrogen-fixing bacteria to live. In the activity, pupils collect decaying logs, expose them to a...

How can a plover bird sit inside a crocodile's mouth and clean its teeth without being eaten? Learners explore food webs which introduce symbiotic relationships such as that between plovers and crocodiles. Pupils complete a review of...
