This video introduces the idea of inertia by using a large globe suspended by water. It shows that acceleration requires an unbalanced force and then explains that an objects inertia is its tendency to maintain its motion unless it is acted upon by an unbalanced force. 

This video shows people’s misconceptions regarding the age of the Earth. It shows how imagining the difference between a million and billion is very difficult for people to do.

The video uses an arm span to model the age of the Earth and shows how recent in the Earth’s history the evolution of more complex...

The Earth spins on its axis, completing a full revolution every day. By why does it do this? One of the most common misconceptions in physics is the belief that constant motion requires a constant force. So many people believe there must be some force in the Earth (e.g. gravity, centrifugal force) that keeps it...

This video does not offer an explanation, but asks several people the question and shows their answers.

A Volcanologist studies the impact of volcanoes on the atmosphere and our planet as a whole. Volcanologists often work to try to understand how to better predict eruptions and minimise the effects on people arising from them. They may use computer modelling or satellite imagery and often work on or around volcanoes...

Dr. Mark Woods explains how the rover technologies must be partly autonomous, since the signals from Earth to Mars take too long for every command to be send from Earth.  The technologies developed for space, also have applications on Earth.

This video is part of a series of ten which look at the one of the...
