Examine the evolution of various species of hominids from their earliest existence approximately 4.5 million years ago to today. In small groups, learners research one of the ten stages of hominid evolution and then create a poster and...

Students practice identifying different groups of living organisms using a dichotomous key. Students also examine the history of an organism and its lineage by writing a paragraph about it and "three generations" of ancestors.

Students study human evolution and the scientific process. They complete the Origins of Humankind Web activity to become familiar with the hominid species as well as the associated evidence found, in the form of fossils and artifacts.

Students explore how the island of Bermuda came to be.

High school learners read and discuss an article about genetic ancestry and genetic ancestry testing. They complete a paper and pencil activity that mimics the function of a DNA microarray and consider the ethics of genetic testing in...

Integrate geography with literature in this interdisciplinary lesson. Begin by reading a poem such as The Time We Climbed Snake Mountain by Leslie Marmon Silko. On a large map, place push pins in the cities or states mentioned. An...

Rotating through five stations, evolutionary biologists explore the question of how changes in DNA facilitate the changes in a population over time. High-quality, colorful cards of animals, skeletons, skulls, and DNA sequences can all be...

Students compare the perceived and actual risks of getting skin cancer, while looking at ways to minimize these risks. They may have very little grasp of the severity of the threat of skin cancer or be unaware of the increase in the...

Fourth graders create enlarged replica of a stegosaurus drawing, using a grid to practice coordinates.

Learners differentiate between renewable and non-renewable resources and identify the different forms of energy and list the advantages or disadvantages of different forms of energy. They also determine the benefits as well as the...

In this planets worksheet, students read a detailed 3 page text about the planets in our solar system. Students then complete 21 true/false and multiple choice questions about planets.

Learners learn along with Ms. Frizzle's class. In this Magic School Bus lesson plan, students find out how partners can help run a race just as Wanda learns that survival on the coral reef often depends on cooperation.

Students use Biology Workbench to explore DNA sequence data for the GULOP gene in humans, chimpanzees, orangutans, and crab-eating macaques and the beta globin gene and its pseduogene in humans, gorillas, and chimpanzees.

Students study about stars, constellations, and myths that accompany them. Then they create their own constellation using black paper and toothpicks and write a myth about their constellation. Their constellation can be viewed on an...

Students explore the basic biology of a pest. They identify the four major kinds of insect mouthparts and explain how they work. Students examine the specific mouthparts and how they can limit food resources and in what environment an...

Students explore the classification system of organisms: taxonomy. They examine prepared slides of Protozoans and record information on a Taxonomy Recording Sheet. Two additional classifying activities are also included in this lesson.

Students examine an ethical public dilemma. In this cultural resource lesson, students role play to examine their personal beliefs regarding the protection of cultural resources. They evaluate possible actions they can take to protect...

Students test what they know about elephants. This worksheet contains 9 multiple choice general knowledge questions about elephants. Answers are provided.

In this biology worksheet, students look for the words that are related to the theme of the worksheet. They also work on the skills of spelling and word recognition.

Students build a soil erosion model to study the importance of soil conservation. They investigate how land forms from both constructive and destructive forces.

Scientists say that flatworms are the oldest living ancestors of those of us that have right and left sides - that means you!

At the online companion Web site of "Evolution," the seven-episode series on PBS, piece together clues to how one of our early ancestors looked as you examine images from four significant fossil finds of Australopithecus afarensis.
