Find out the best way to survive a 150 meter elevator fall, and at the same time learn about gravitational acceleration and understand Newton’s Laws. Your monthly dose of hypothetical physics scenarios is here, and today we’re dropping...

Behavioral Adaptations of Animals explores the behavioral adaptations of various animals by discussing how those adaptations enable them to survive in different environments.

“Plant Parts” discusses the functions of a plant’s main parts.

Changing Traits for Adaptation recognizes that inherited traits of animals can change over time to adapt to their environment for survival.

Nutrients for Energy demonstrates how the body uses energy, including calorie intake and output.

Physical Adaptations of Animals explores the physical characteristic adaptations of various animals by discussing how those adaptations enable them to survive in different environments.

Historian Martin Jay, UC Berkeley, describes how a study of history can sharpen our moral understanding, showing that, rather than adhering to inflexible rules of behaviour, each situation presents a unique set of “competing moral...

Psychologist Barbara Fredrickson (UNC Chapel Hill) addresses a fundamental puzzle: What evolutionary role might positive emotions play?

Moving on from organisms and populations, the next tier on the scales of ecology is communities. These involve all the populations of organisms of different species that live in an area. How do they interact? How is the community...

The video “Amazing Camouflage” explains how animals use forms of camouflage to survive in their habitats.

A video entitled "Plants: How Do They Grow in Unusual Places?" which uses the example of a flower growing from a sidewalk to examine the wide variety and adaptability of plant life.

Research consensus at this time is that animals and humans differ most fundamentally in their ability to recognize themselves. Human beings are capable of self-analysis, mental time travel, imagination, abstract reasoning, cultural...

Evolution “is the net change in organisms or a population over the span of many generations.” This change in organisms or populations happens through DNA mutations and reconbination and is passed down to the next generation through...

In this video, we learn about Charles Darwin's journey on the HMS Beagle and how it led him to develop the theory of natural selection. Through examples of overproduction, competition, and variations within species, we understand how...

The moment you think about astronauts, what comes to your mind would probably be a picture of an astronaut in a white spacesuit experiencing weightlessness in the vast expanse of space. Or perhaps you don't imagine a white astronaut. You...

This video highlights the importance of breathing good air for humans, plants, and animals. The video also mentions the harmful effects of smog and acid rain. It emphasizes the need for human effort, technology, cooperation, and a strong...

We learned about how altruism can evolve in certain species, which involves cooperative behavior among closely-related organisms to enhance the inclusive fitness of the group. But this is also achieved through spiteful behavior towards...

It explains causes for water pollution, international standards for drinking water, biomagnification, eutrophication.
