Students examine the concept of extinction by studying dinosaurs. In this living environment lesson, students view dinosaur video clips and define the word "extinction." Students visit the "Zoom Dinosaur" website to investigate various...

Students study Alfred Wegener's theory of continental drift and how the continents were connected in one large land mass called Pangaea. They examine plate tectonics and the theory that the earth's surface is composed of large moving...

Young scholars participate in a three part unit about biomes. Part one, students research the biomes of North America and part two consists of research on zoos and a field trip to a zoo. While part three ties together the first two...

Students examine animal reproduction by interpreting data and making arguments and then create their own graphs to explore relationships of organ systems. This lesson includes an individual worksheet and a reflective review question for...

Students are able to extract and observe a visible amount of DNA from Escherichia coli cells. They discuss the properties of DNA. Students confirm the presence of DNA by a reaction with an indicator.

Students examine the concept of biodiversity. Using the internet, they complete small activities in which they work together. Using the information they collected, they create a class book, make murals and write in their journals.

Students examine the population of aphids. They identify adaptations they have made for their environment. They make predictions, test their hypothesis and collect information that either proves or disproves their theory.

Fifth graders determine that carbon dioxide is a gas given off during respiration and that oxygent is the gas that is absorbed during respiration. They determine the air capacity of the lungs.

Third graders predict salmon migration routes and explore how dams affect the salmon migration. They explore the cultural significance of salmon to the Nez Perce people and design technology to aid salmon migration.

In this lesson, students compare various types of relationships among organisms (i.e., biotic interactions). Students will: explain the roles of producers and consumers, and predators and prey in an ecosystem. Explain the levels of order...

Species interact every day. That interaction is a vital part of how organisms develop and change over time. When you study species, it is important to watch the way they interact with their surroundings. There are four basic types of...

Create the parameters of your own ecosystem by choosing which producers and consumers live there. Visualize how the food web operates and species populations change. This simulator mimics the food web within a typical ecosystem and gives...

Learn about three different marine ecosystems: coral reefs, the continental shelf, and the deep sea. Interactive game included, which will help players chart the interrelationships among organisms that live in each ecosystem.

This lesson will discuss the interactions of and interdependence among living things. It is 2 of 4 in the series titled "Living Organisms and Their Environment."
