Using a diagram of an open tube an explanation of possible wave patterns is built up.  Firstly, the fundamental mode of vibration is drawn, followed by the second and third harmonics.  For each illustration the number of waves is calculated, i.e, ^λ/₄, ³/₄ λ and ^5...

This video explains how nodes and anti-nodes are formed in standing (stationary) waves.  It shows how the distance between two nodes = ^λ/₂.  A series of standing waves are drawn to show the fundamental wave and its harmonics.  The number of half wavelengths for the fundamental and second,...

This collection includes some activities for primary and secondary aged pupils which could be linked to Star Wars day.  

There are several activities looking at exoplanets and the search for alien life elsewhere in the Universe, which could be used to challenge the scientific validity of the film series....

This resource, from the Royal Observatory Greenwich, is a beautifully animated video giving a short overview of the life cycle of stars, but crucially how, from Earth, we can observe the different phases of star evolution by plotting all the...

Produced by the Royal Observatory Greenwich, this booklet introduces the sidereal day and shows how star trials can be used to calculate the length of one sidereal day. Included in the booklet are instructions on how to create a star trial photograph using a DSLR or bridge camera. Supporting documents that help the...

This Science upd8 resource revolves around the topic of the universe. A mission brings space dust back from the tail of a comet. The dust may reveal secrets about the origins of the universe and life on Earth. Students must defend the mission's $200 million price tag and produce a graphic to support their talks. ...

This Nature of Science book looks at the history of astronomy and how scientists understanding of the solar system, forces and gravity has developed. The story includes the revolutionary ideas of Copernicus, Galileo and Newton and the theory of magnetism.

The chapters are:

1. Stars and gods

2....

NASA has been responsible for some fantastic images of space, especially from the Hubble Space Telescope. These are a few of the images of stars, nebulae and galaxies. More images are available from the  NASA website

Designed for parents to use at home they help children develop their science, technology, engineering and maths skills. These activities are easy-to-resource and provide children with the stimulus to talk about the world...

Starters for Science consists of lots of easy to run activities suitable for children from 4-11.  Designed for use in school or at home they help children develop their science knowledge and...

A Catalyst article looking at strategies for ensuring that there is a plentiful food supply in the future and how this can be sustained.

The article looks at three main areas for scientific investigation:

*Fertilisation

*Pest control

*Genetic modification

It also looks at...

This video covers the basics of state changes in water. It explains how the distance between molecules and their motion can be used to explain the three states of water (solid, liquid and gas).  

Contrails occur when water vapour from jet engines condenses – only when the temperature and humidity conditions of the air is right. Contrails act like greenhouse gases. Marc Stettler from Imperial College, London is interested in guiding aircraft to fly where conditions are right, reducing contrail formation....

These diagnostic questions and response activities (contained in the zip file) support students in being able to:

• Identify when an electrostatic force is acting in familiar situations. 
• Describe how objects with a positive or negative charge attract or repel other charged objects.
• ...
