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

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...

The video explains that as pressure is exerted onto the ice it melts and it is the liquid water, in contact with the ice, that makes it so slippery.

In this classroom resource pupils learn how space debris is generated. It includes two investigations looking at how collisions between objects can lead to further collisions, and how impact causes some materials to fracture into many particles using crisps.

The resource includes pupil worksheets as well as...

This lesson introduces ideas about combustion, incomplete combustion and the production of carbon monoxide, particulates and their relationship to health.

Learning outcomes:

• Students could produce and write symbol equations for the combustion of carbon and methane using models.
• They...

Planetary scientist, Professor Andrew Coates, explains why scientists look for the evidence of signs of past life on Mars.  He talks about the history of Mars and the current harsh environment on the planet. This video is part of a series of ten which look at the one of the elements of the European Space Agency’s...

This video explains the structure of DNA and the role of histones and methyl groups in deactivating one of the X chromosomes in a female.  The deactivation of one X chromosome is random. As mitosis reproduces cells, they may contain the X chromosome inherited from the father or the mother.  This can’t be seen in...

This collection provides a cross-curricular learning package which supports learning about the work of Dr Edward Jenner on developing a vaccine for Smallpox. All activities are based around a short film, which highlights Jenner’s work from the viewpoint of a child living at the time in which he worked on the...

This activity supports learning in science and English, using the context of Dr Edward Jenner’s work on developing a vaccine for Smallpox. Children learn how, through vaccination, Smallpox became the first and only human disease to be eradicated. They look at what other vaccines exist today and the current battles...

This resource supports learning in literacy and drama and science, all based around the life of Edward Jenner. After watching a short film, children discuss some of the main differences between plays and films, beginning to think in terms of cinematic storytelling. They use their scientific and historical...

One way to cross wide gaps is to repeat bridge units, such as beams or arches. Piers are then necessary to act as supports for these repeating units. The more piers, the greater the blockage to the flow beneath the bridge.

Lesson Objectives

• Students could be able to predict the...

In this activity, from the Institution of Engineering and Technology (IET), students read about a Wi-Fi system (often called WLAN — wireless local area network) and produce a diagram to show how the ‘wireless’ part is, by necessity, short-range. Mostly, the signal is...

The resources in this collection focus on the wider issues relating to society and health. They provide a ‘big picture’ in relation to the connection between society and health and the development of new technologies. The activities allow students to explore social, ethical, economic and health issues relating to...
