Students research the History of Pigeon Creek (or any watershed in your area). In this environmental science lesson, students conduct field tests such as pH and nitrates. They collect data and compare what they collected with other groups.

In this measuring worksheet, middle schoolers determine the mass shown on the scale, review how to read measurements in a graduated cylinder, and determine which measuring method is more precise. This worksheet has 5 short answer...

Students create graphic organizer webs that illustrate their thinking about seasonal physical and biological changes caused by changes in sunlight. They identify the central role of sunlight in living systems.

Students conduct an experiment to demonstrate how fruit fly populations are controlled by spiders. They observe a variety of environments with fruit flies and spiders and consider how vital spiders are to controlling the insect population.

Students examine NASA's SeaWiFS Project Web site to explore how the SeaWiFS Project monitors environmental and climatic changes in the oceans and atmosphere. They answer questions and write a summary in support of continued funding for...

Students predict the effects of water, light, and soil on the development of a plant and then design an experiment to test their predictions.

Young scholars use the Internet and other resources to find insect common names that begin with each letter of the alphabet. They write a brief description of each insect, focusing on what the insect eats and where the insect lives.

Fifth graders examine animal adaptations and how they meet their needs in a variety of environments. They discuss how they might adapt to their own environment before discussing how an animal could adapt. Next, they complete an...

Students examine the white shark. They think critically about a set of shark facts and predict whether the statements are true or false. Students describe a year in the life of a white shark living in the Red Triangle. They create a...

Third graders complete activities to become familiar with the content and vocabulary related to biomes and ecosystems in order to mainstream into the classroom.

Students use their personal knowledge and the Internet to discover where and how spiders live. In groups, they discuss their experiences with spiders and how their lives differ from other insects. They use new vocabulary to discuss their...

Young scholars identify and discuss the adaptive characteristics and behaviors of fish. They view slides of fish, and design and create a model of a fish of the future, listing the ways their fish adapt to survive.

Young environmentalists study the effects that pesticides have on birds, such as the peregrine falcon. They also look at predator/prey interactions. Some wonderful in-class activities accompany an inventive lesson. After an activity that...

What is a dichotomous key? When your kids ask, hand them a learning exercise like this one, to explain it. They use the key to identify four different trees, based on the budding twigs they've produced. Tip: Have learners extend this...

The following is a tutorial of food chains, food webs and food pyramids.

Two differentiated tasks about food chains and webs. In the more challenging task, young scholars construct a food web to show the relationship of the animals and plants in a given environment. In the lower level task, students create a...

For this lesson, students learn about marine food webs and pyramids, and how energy flows through a marine ecosystem. They then research a marine organism and its role in a marine food web. The class pools their information to create a...

This lesson, supported by the provided power point lecture (LESSON 1 and 2 Ecology Lecture Supplement ), introduces students to the concepts of food chains and food webs. Through its use, students learn the difference between producers...

Students learn about energy flow in food webs, including the roles of the sun, producers, consumers and decomposers in the energy cycle. They model a food web and create diagrams of food webs using their own drawings and/or images from...

Learners will build a food web diagram and illustrate the movement of matter through a series of food chains. Resources include detailed plans, examples of student work, videos of the lesson in action, and sample food webs.

Explore the food web in a coral reef with these illustration. Identify the consumers, producers, and decomposers that are located within this ecosystem. Site includes illustration exploring the different food chains as well as questions...

Students construct possible food webs for six different ecosystems as they learn about the roles of producers, consumers, herbivores, carnivores and decomposers.

[Free Registration/Login may be required to access all resource tools.] Videos, texts, activities, and assessments about food chains and food webs in an ecosystem.
