Students experience, through a "dig," the historical discovery of fossils which increasingly link whales to earlier land-dwelling mammals. They encounter the intermediate forms which show changes that lead to the modern whale.

Why is diversity in biology so important for an ecosystem? Explore biodiversity, evolution, and natural selection with a presentation for your biology class. It features clear information, activities for further understanding, and...

Students identify one object that would tell the story of their lives. In groups, they determine what can and cannot be told from objects left behind. After watching a video, they compare and contrast chicken bones to human bones. To...

Students explore whales and how they have adapted to survive in the ocean.  In this whale adaptations lesson plan students complete several activities that allow them to investigate animal adaptations.

Students are guided through a process in which three questions are addressed by retrieving beta hemoglobin sequences from online databases, and using online tools to compare those sequences in student-selected animals.

Are you looking for evidence that your high schoolers are adapting to the concepts of natural selection and evolution? Assess their knowledge with a pretest and posttest. Naturally, you can select and adapt the worksheet to be the...

Students comprehend what is meant by Cultural Evolution and that it primarily applies at Human Evolution, but that there are examples in higher mammals such as a killer whales, dolphins and great apes of particular groups by exploring...

In this comet tails and stars activity, students read about the star Mira and the vast clouds of gases it emits. They use a photograph from the Galaxy Evolution Explorer satellite to solve 5 problems about the scale of the image, the...

A well-designed, comprehensive, and attractive slide show supports direct instruction on how sonar and echolocation work. Contained within the slides are links to interactive websites and instructions for using apps on a mobile device to...

One of the most diverse environments on Earth is the ocean. Young scientists explore the living things found in the ocean during an exciting seven-lesson unit. Their study includes organisms from plankton to invertebrates...

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...

Young scholars study the characteristics of organisms that are a part of the phylum Chordata.  In this organisms lesson students identify mammals that are native to Saskatchewan.

This graphic from Evolution, traces the evolution of whales from land-dwelling mammals to the aquatic creatures we know today. A PDF is included that diagrams the evolutionary process that is believed to have taken place.

Around 50 million years ago, the mammalian ancestor of today's whales returned to the ocean. In this genomics science fair project, you will use mitochondrial protein sequencing to trace the evolution of whales and identify their closest...
