When light hits something, a number of things can happen: it can be reflected, refracted, diffracted or absorbed. But what does this mean? Physics - Waves - Learning Points. Manipulation of light is vital to our survival. Light waves...

Everything we eat contains calories. We need them to function and carry out everyday tasks. How do we know which foods are right to eat and which contain 'empty calories'? Chemistry - Chemical Industries - Learning Points. Calories are...

We investigate the amount of energy stored in maize snacks and peanuts by burning them. The food is placed under an aluminium beaker of water before being set alight and the temperature change of the water is recorded. We can compare the...

Discover how energy from the Sun is converted into different forms, and what happens to energy that is 'lost' from a system. Physics - Energy And Radioactivity - Learning Points. The Sun provides almost all the energy on Earth. Energy...

Discover how matter and energy are fundamental to sustaining life, from the foods we eat to the air we breathe. This video explores the crucial role of chemical energy derived from food, which powers everything from our daily...

Plastids and Mitochondria examines energy transformations by describing the fundamental roles of plastids and mitochondria.

Photosynthesis analyzes the process of photosynthesis by describing how cells and organisms acquire and release energy.

In this video, we explore the concept of energy conversion and how different forms of energy can be transformed into one another. The video also touches upon how plants convert electromagnetic energy from the sun into chemical energy...

A series aimed at Primary School students learning all about the Ocean and its inhabitants in their science classes. This video in particular will take students through the basics of seaweed forests, something they may never have heard of.

This video is a lecture on efficiency where the speaker explains how to calculate the efficiency of a device and identify the energy transfers that take place. The video starts with an introduction to Sankey diagrams that detail all the...

A conversation with Lynn Rothschild, astrobiologist and synthetic biologist in the Earth Science Division at NASA’s Ames Research Center in Silicon Valley.

In this video, the teacher explains why zombies are impossible by examining the stages of death and the decomposition process in the human body. They discuss the effects of rigor mortis, lack of oxygen to the brain, and the breakdown of...

We hike in the Australian Outback with Abigail Allwood to visit the most ancient fossils on Earth, and track the imprint of life over space and time with David Grinspoon.
