Ecosystem, human body system, weather system. We hear the word system a lot, but what does it really mean? In the activity, pairs or groups of learners discuss how a bicycle is a system and then analyze objects in their classroom and...

Field trip! The class will review what they know about organisms that dwell in freshwater ponds, then trek down to the old water hole to collect specimens for examination. This includes several web links, useful tips, and an excellent...

Searching for an activity that allows emerging biologists to explore symbiosis up close and personal? Pupils collect samples and view lichens through a microscope and conclude with a discussion about the relationship they have...

Students simulate a predator-prey interaction in an ecosystem. Students use different size squares cut from paper to represent predators and prey. They simulate the interactions of the species by following instructions for the capture of...

See the underwater world through a different pair of eyes! Middle school marine biologists identify deep-sea organisms by examining images taken by an ROV from the Okeanos Explorer. After determining what creatures lie beneath the...

Students explore aquariums. In this fish and ecosystems lessons, students establish a freshwater aquarium environment using materials provided. Students read about and care for the classroom fish.

Twenty questions make up an assessment designed to test super scientists' knowledge of ecosystems. Scholars answer multiple-choice and short-answer questions about organisms, food chains, energy flow, and more.

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...

It's all connected. Classes create a web to connect living things in a local ecosystem. They create cards with both living and nonliving things found in their areas while considering the characteristics of each. After they have a good...

How far does the human hand reach?  Five interactive lessons lead classes through a unit exploring the human impact on ocean resources, pollution, and even extinction. Learners discover how their decisions affect the ocean...

In collaborative groups, young ecologists measure the temperature, pH, and dissolved oxygen for three different freshwater samples. They examine each sample with a microscope and record observations on the microorganisms in the pond...

At first glance, grassland ecosystems might seem dull and uninteresting, but once you start to explore it's amazing the things you'll find! Through this series of engaging lessons, activities, and experiments, elementary students examine...

Is it a producer, carnivore, omnivore, scavenger, or decomposer? Different relationships among organisms are explored here. It is a simple, multiple choice assignment. Use it as a quick warm-up or quiz.

Create a simulation of acid rain in your classroom with lemon juice and bean plants to help kids study the effects of pollution on plants. In addition, learners will listen to a story and write responses based on guiding questions.

What makes each one of us unique? Lead your class in this exciting and educational activity as you uncover traits that show how each individual is different from another. Pupils explore facts about DNA technology and predict the...

Students model a food web and create a miniature ecosystem. In this animal interactions lesson, students engage in a role playing game which simulates a food web. Students then build miniature ecosystems using pop bottles, snails, plants...

Students become familiar with the temperate rainforest.  In this forest ecosystem lesson, students identify the producers, consumers and decomposers in the forest ecosystem.  Students sort cards and identify the trophic level...

Students engage in a lesson that is about the concepts related to the careful balance of an ecosystem. They identify the beneficial and harmful relationships that can exist with diverse populations in an ecosystem. The lesson includes...

Students explore the predator-prey relationship using an interactive game. In this biology instructional activity, students compare their physical attributes. They explain how  predators develop to make it stronger and efficient as...

Students design an experiment to test the variables involved in the hatching of the Bruchid beetle.

How many animals can live in a climate as cold as Mount Everest's? Find out with a science lesson all about biodiversity. Activities include research, presentations, group work, coloring maps, and a simulation of a food web.

Young scientists discover how sea otters' habitats have changed due to human impact. Through conversation, video observation, and story reading, scholars identify how human interactions change a specific ecosystem in both positive and...
