The heartbreaking story of Alfred Wallace's loss of collected evidence opens this documentary about the development of the theory of evolution. You will find supportive resources to use with the movie in your biology class.

In a fun and interactive two-day lesson, learners sort anole lizard pictures by appearance. Next, they watch a video about the anoles and re-sort based on the information in the video. In addition to physical characteristics, budding...

After watching an engaging 13-minute video about the colorless blood of icefish, future ichthyologists examine icefish blood and non-icefish blood (blood samples are simulated with Karo syrup mixtures) to determine advantages of...

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...

The pocket mouse can be light brown like the sands of the desert, or dark brown like the volcanic lava flows that are interspersed throughout New Mexico's Valley of Fire. It seems that predators have weeded out light colored mice in this...

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...

Does the human body evolve as quickly as human culture? With a stellar 15-minute video, explore the trait of lactose intolerance. Only about 1/3 of human adults seem to still have the enzyme lactase and therefore, the ability to digest...

Adaptations must be made as environments change. This fabulous presentation features Icelandic icefish, a transparent, scaleless specimen that even has colorless blood. Genetics and adaptations concepts are explored as scientists study...

As the great and hilarious Tim Minchin once said, "Science is simply the word we use to describe a method of organizing our curiosity." Science is more than just a guess; it is based on questions, observations, and evidence. High...

You're a time traveler, reaching back 400 million years! See how rainforests evolved over time. Breathtaking views and captivating close-ups of rain forest critters engage learners and create interest.

Why do some people think evolution is a controversial topic? This video does a wonderful job of explaining the controversy around evolution in an unbiased way. Showing the source of controversy from both a scientific and religious...

Find out how evolution really works. This video explains the concept of adaptation and natural selection to describe how evolutionary change occurs. We'll find out that natural selection is comprised of four key components; each...

Clear up any confusion regarding human evolution and ancestry with this comprehensive clip. Using scientific evidence and concrete examples such as DNA, this clip explains human evolution in a way elementary learners can understand. This...

Introduce your young scientists to Charles Darwin, his observations, and how those observations became the basis of the theory of evolution. Use this clip to build an understanding of scientific observation, data collection, and the...

What is a theory? Learners are primed for a lesson on theory, science, and the use of scientific evidence as it's used to prove evolution. This is a great video for elementary schoolers and can be used to introduce the concept of...

High schoolers compare the evolution theories of Lamarck and Darwin. They use self-assessment and a video to increase their knowledge of evolution theories. They research questions and present them to the class.

It's not often that you come across a clever laboratory activity that is both imaginative and comprehensive! Using M&M's and Reese's peanut butter candies to represent two different clam species, young biologists test for "relative...

A diagram, data table, and reading passage top this resource. Through it, biology beginners are introduced to the concept of natural selection. They answer some questions and then participate in a simulation using fabric as a habitat and...

The living environment, from the interior of a cell to the complex relationships among populations, are queried in this final examination. Learners look at air pollution maps, diagrams of cells, population graphs, and drawing of cells....

The 2005 version of the Regents High School Examination in the area of ecology is as comprehensive as previous years' exams. It consists of 40 multiple choice questions on everything from the structure of DNA to the interactions within...

Tne New York Regents High School Examinations are comprehensive and include various styles of questions, includingmultiple choice and the analysis of graphs. This particular version, the 2008 Living Environment exam surveys a variety of...

An exceptionally creative approach is taken to assessing your biologists' grasp of natural selection concepts. They are to imagine hosting Charles Darwin for dinner and having, to their surpise, a few other noted scientists crash the...

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...
