Professor Andrew Coates and Dr Ian Hutchinson explain how the ExoMars instruments, the Pancam and Raman spectroscopy instruments can be combined to help scientists identify areas of interest on the surface of Mars.  The video shows how field trips are important to learn first-hand the challenges that the ExoMars...

This video explains why astronauts float. The common misconception is that there is no gravity in space, yet the astronaut is in the Earth’s gravitational field.  Rather, the astronaut is falling towards the Earth (as is the spacecraft). However, their horizontal speed is 28,000km/hr. This and the curvature of the...

Hydrologists are principally involved in monitoring, managing and conserving the Earth's freshwater resources. They study the quantity, trends and implications of freshwater in rivers, lakes, reservoirs, aquifers and glaciers. They also monitor and analyse rainfall. A Levels: Geography, History, Physics

This video takes a light-hearted look at motion. It applies Newton’s second and third laws to explain how motion occurs in the space shuttle and a jetpack. Misconception about reaction forces are identified (the need for the ground/lake for a reaction force to be generated) for motion to happen. This explains how...

Joanne uses her skills and knowledge to advise satellite operators on the legal aspects of launching and operating a satellite in space.  With the growth of more commercial satellite companies there is a demand for more lawyers to advise and write the rules governing space activities across the globe. 

There...

Karsten works at the University of Leeds as a scientific researcher, in the School of Earth and Environment.  He uses images taken by satellites to look the movement of structures such as railways, roads and gas lines.  He also examines the movement of the Earth due to volcanic eruptions and earthquakes. ...

This video discusses the use of video to learn science.  It shows that to be most effective a misconception is introduced at the beginning. The more mental effort used the greater the effectiveness.

This video explains that moving objects have kinetic energy (E_k) and shows how E_k is proportional to both the mass and velocity of an object.

By combining the formulae F=ma and W=Fs to obtain W=mas and using v²=u² + 2as (assuming u²=0), E_k=...
