This Catalyst article looks at sperm whales and their ways of communications. Sperm whales can dive deep into the ocean. They use sound waves to communicate in the dark and to detect their prey.

This short activity introduces students to the ideas of the footprint and resolution of an image, asking them to choose and use appropriate methods to calculate how these quantities would change as they moved a camera to a series of vantage points above the surface of the Earth

This article from Catalyst looks at aurora borealis caused by the interaction of the solar wind with the Earth's magnetic field. It also explains how satellites are testing thoeires of how this happens. Auroral light emission occurs at roughly 100 km altitude. Energetic electrons in the solar wind cause the...

This activity uses a humorous video to raise a serious question: can science tell us what animals are saying, and interpret their emotions? The Bow-lingual dog translator claims to detect animal emotions by analysing bark sounds waves. Students use research evidence to decide whether the device does what it claims...

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

• Understand that a force makes things change: the speed, direction and/or shape of an object.

• Explain changes caused by more than one force acting on an object at the...

From the Science and Technology Facilities Council (STFC), this resource describes the new and exciting subject that brings together many different branches of science. Astrobiology is the study of how life formed and developed on the Earth, the conditions that made this possible and whether these conditions can...

Geothermal energy is the heat produced by decay of radioactive isotopes deep within the Earth. The temperature at the centre of the Earth is thought to be around 5,000°C, with the temperature reducing toward the surface. It is estimated that 99.9% of the planet is above 100°C. Geothermal energy is considered a...

By constructing a model of the constellations in the zodiac, students can learn about the relative motion of the Sun and the Earth. Students can find their own star sign and discover how the view from the Earth will change as the Earth orbits the Sun. The model allows them to see how the night sky changes over a...

This video explains how atoms are the fundamental building blocks of all matter and that they are made from sub-atomic particles (proton, neutron and electron). The simple structure of a hydrogen atom is made from plasticine. The video explains how adding a neutron to the hydrogen atom does not change its...

Much of this video shows how many people do not understand how the seasons are caused.  There is a small section at the end that attempts to clarify the cause.  

This resource, from the Royal Observatory Greenwich, looks at what information we can gather by viewing (but not visiting) different parts of the universe. 

The...

This paper, published in 2012, summarises...

This challenging video takes a philosophical approach to discussing what information is. It begins by equating information to entropy. Entropy is explained as the degree of order or alternatively randomness that exists. Examples of ordered information are the arrangement of molecules in DNA, letters in words and...

This Catalyst article discusses what physics is. Physics is a subject which seeks to answer fundamental questions about the nature of matter and the Universe in a self-consistent way.

The article is from Catalyst: Secondary Science Review 2015, Volume 26, Issue 1.
