Scientists noticed animals with backbones share similar bone structure despite having different forms, such as fins, arms, and wings. Young scientists gain an appreciation for evolution by understanding the history of the theory. They...

A somewhat amusing assignment, this worksheet lists statements that an ancient organism may have made and asks learners to determine what geologic era that each may have lived in. It uses witty word puzzles and fill-in-the-blank-style...

Addressing the idea of intelligent design, as well as a number of creation myths, this presentation gives a measured and scientific perspective to the beginning of the world.  It includes a graphic on the Big Bang Theory, evolution,...

Using meters as years, your class works together to map out the geologic time scale on a football field. Plenty of background information is included in this lesson plan as well as several resource links and a student worksheet. Your...

Take it all the way back! Young scientists discover the changes that took place from the time Earth became solid to present day through an interesting interactive. The resource guides users through key events that have shaped our world...

Got milk? Only two cultures have had it long enough to develop the tolerance of lactose as an adult. Learn how the responsible genes evolved along with the cultures that have been consuming milk. This rich film is supplied with a few...

Five pages take biologists on a generalized survey of the origin of life. Queries are made regarding theories of how life developed, ancient Earth conditions, and the ever-changing field of taxonomy. The experiments of different...

Bring together a study of two major scientific topics with a lesson on the relationship between pollution and evolution. With the help of a PowerPoint presentation, hands-on activity. and class demonstration young scientists learn...

Learners investigate the history of Earth by creating a geologic time scale.  In this Earth History lesson plan, students practice sequencing events in their life as a way to get familiar with creating a time scale.  Learners...

Earth didn't always have oxygen, so what caused the change that allows humans to live here? Learn about the change in O2 levels throughout geological history through an interactive graph. Each section offers greater detail on the changes...

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...

Mammals are some of the newest organisms to appear on Earth. Young scholars complete an activity that results in a timeline showing the appearance of different types of living organisms. Provided with a list that spans from prokaryotes...

In this review of evolution worksheet, learners complete 50 multiple answer questions on Darwin's theory and the history of life on Earth.

This quiz just looks neat! It has two cell diagrams for biology class members to label. They also describe the function of each organelle. A prokaryotic and eukaryotic cell are displayed for them to compare, and then they fill in the...

Young scholars gain a deeper understanding of geological time and the evolution of life on Earth. They use iMovie to tell a complex story of a discrete time period with narration and images.

Students research the history of the theory of evolution and make a comparative timeline of events in world history and in the history of evolutionary theory.

Here's a topic classes can really dig—the fossil record. Use the well-organized and thoughtful road map to take eighth graders back in time to unearth the answer. Learn how our climate has changed, and how organisms have...

Star light, star bright ... just how long can you wish on that star? Well, it depends on its mass. The presentation explains the life cycle of stars based on their sizes. Scholars learn about the life expectancy of a star based on the...

In this Earth's history worksheet, students will complete 5 true or false questions based on the early history of the Earth. Students will match 7 fossil vocabulary words to their definitions. Students will complete 4 short answer...

Students are taken on a simulated "voyage" backward in time, to the beginning of our planet. They "witness" that beginning, the origin of life, and a number of key events from then to the present.

Students investigate hominid evolution to learn the difference between a relative and an ancestor. They study the emergence of bipedalism and the related physical adaptations and cultural ramifications, and chart patterns of hominid...

High schoolers investigate the models for the origin of modern humans and the conditions that facilitate speciation and evolution. The classification and nomenclature of hominid species is also examined.

Step into the role of a zoo director with several activities about animal training and running a zoo. Kids calculate the amount of food each animal needs, design a habitat for penguins, decide how to breed bottlenose dolphins, and train...

In this earth history worksheet, students answer 12 questions about geological time, the eras of Earth, the changes taking place in early Earth and the life present during the eras. They also answer 2 questions about the Paleozoic Era.
