Fourth graders investigate ecosystems. In this ecosystem lesson, 4th graders explore producers, consumers, and decomposers and study the interdependence of each.

Students watch videos and fill out worksheets about the turtles and their journey to the Costa Rican beach. In this turtles lesson plan, students learn and discuss survival, predator and prey, and stages of development.

In this unit of lessons, students examine solid waste and recycling. They discover the concept of decomposition. They also observe the decomposition process and make observatins.

Third graders identify features of producers, herbivores and carnivores. They discuss the features that aid in survival for those animals. They organize animals into categories to complete the lesson.

Third graders research ecosystems, the work of ecologists, John Muir's contribution to the environment and an endangered species of their choice. They read books, participate in discussions, and write reports.

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.

Young scholars 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...

Young scholars explore the physical characteristics, distribution and habitat of termites. The instructional activity focuses on the termite as a social creature contrary to most other insects.

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

Learners complete a unit of lessons on animals and animal conservation. They observe a square meter of ground outside the school, set up a model environment, analyze an owl pellet, grow bread mold, and explore various websites.

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

Students 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.

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 participate in a virtual field trip to Lake Superior. In groups, they perform experiments in which test the level of toxins and bacteria in the water. They also watch video segments life in the lake and discuss their observations.

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...

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 explore DNA structure using materials such as Twizzlers, small colored gumdrops and/or toothpicks.

Trace the energy transfer through food chains and food webs. Check your understanding by hovering your mouse over questions to reveal the answers.

This lesson plan, 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...

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

View examples and learn how animals impact the food chain.

Is the food chain shown above accurate? Does the first link depict a producer, the second link a herbivore, and the third link an omnivore / carnivore? Students must correctly determine whether a species is a producer or consumer, and...

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...
