Dinosaurs were huge—it's common knowledge. So why aren't modern mammals anywhere near that size? In this episode of SciShow, Hank gives a quick run-down of the reasons scientists think the land mammals of today are nowhere near the size...

Paul Andersen explains the major classification terms in ecology and how a community can be measured by species composition and species diversity. The symbiosis of leaf cutter ants is included. The podcast ends with a discussion of...

For decades scientists believed that monkeys could not speak human language due to an anatomical difference in vocal tracts. Today, we're not so sure that this is the limiting factor after all.

What's on Elon Musk's mind? In conversation with head of TED Chris Anderson, Musk details how the radical new innovations he's working on -- Tesla's intelligent humanoid robot Optimus, SpaceX's otherworldly Starship and Neuralink's...

Population ecology is the study of groups within a species that interact mostly with each other, and it examines how they live together in one geographic area to understand why these populations are different in one time and place than...

In this video, Jonathan from the Institute of Human Anatomy discusses how the lungs supply the oxygen necessary for exercise, some of the mechanics of breathing, the muscles involved, as well as if and how the lungs can adapt to exercise.

The rate of photosynthesis is affected by light intensity, temperature, carbon dioxide concentrations, and chlorophyll. In this video we explore exactly how, and also how farmers can use this knowledge to increase the yields of their crops.

a video entitled “Population Ecology: What Causes Populations to Change?” which discusses the roles of organisms in a habitat and explores how organisms affect one another and limited resources when interacting.

This video explores the concept of limiting factors in photosynthesis and how they can be represented in graphs. The three key limiting factors of light intensity, temperature, and carbon dioxide concentration are discussed, and the...

The video discusses the factors that influence the rate of photosynthesis in plants, including light intensity, temperature, and carbon dioxide concentration. Different zones are shown to demonstrate the impact of each factor on the rate...

This program covers part 2 of the very important topic of the atomic theory of matter. We discuss how atoms combine together to form new compounds. Students review the law of conservation of mass and how the mass of the substances at the...

This video explains the relationship between light intensity and photosynthesis in plants. The concept of direct proportionality and a linear relationship between light intensity and photosynthesis rate is discussed. The video then goes...

In this video, the teacher covers key concepts related to communities in ecology. They discuss how different populations interact within a community, the role of limiting factors in population dynamics, and the importance of tolerance in...

This video explains how farmers can enhance the growing conditions for their crops by using greenhouses. The video discusses how temperature, light, and carbon dioxide concentration can all be controlled in a greenhouse, making it...

The video is a lecture presentation on improving crop yields. It discusses various methods that farmers can use to increase the mass of useful product they get from a crop. The presentation starts by highlighting the importance of...

This video discusses the rate of photosynthesis. The video explores the three key limiting factors to photosynthesis: light intensity, temperature and carbon dioxide concentration. The video also highlights the importance of chlorophyll....

P.E.I. Premier and Chair of the Council of the Federation Rob Lantz met with Prime Minister Mark Carney in Ottawa ahead of the budget to discuss a first ministers' meeting, energy and trade. 'It's time to get Team Canada back together,'...

Finally, the wait is over! We’ve ridden the highly-anticipated, all-new Royal Enfield Guerrilla 450, and our review video covers everything from its engine to its features, and most importantly, its on-road performance. With prices...
