One of a series of resources from Science & Plants for Schools (SAPS) investigating key topics in plant biology. A reliable way to demonstrate photosynthesis in the classroom. When the pond-weed Cabomba is placed in a solution of sodium hydrogen carbonate in the presence of light of appropriate intensity, it...

A Catalyst article about experiments on surface tension based on a simple test that can be conducted at home or in a school classroom.

This article is from Catalyst: Secondary Science Review 2007, Volume 18, Issue 2.

Catalyst is a science...

This is one of a series of resources from the IET designed around the theme of the future of flight with the purpose of developing pupils knowledge and skills in design technology, engineering, science and mathematics. In this activity pupils measure noise produced by a range of activities using a sound meter to...

Purpose: Finding the speed of an object is a fundamental step in understanding the relationships between forces, acceleration and motion. Practical measurement of speed in a classroom can be challenging as methods employed can be complex and time consuming. Using the camera function in a mobile computer (smart...

This Cape Farewell video clip explains that scientists use satellite images and optical measurements to detect phytoplankton in the oceans and that they use various methods to capture their samples. Scientists are shown looking at some of the plankton samples they have captured.

Produced by the Royal Observatory Greenwich, this booklet introduces the concept of parallax and how it can be used to measure the distance to stars, using the constellation of Orion as an example. Included is an online video that demonstrates parallax in everyday contexts and in astronomy.  It also discusses the...

Mechanics and Properties of Matter is one of the titles in the series of ASE Lab Books that were published in the early 1970s for the Association for Science Education. Each title brought together the best of the teaching notes and experimental ideas from members of the...

Work done in this Nuffield 13 - 16 module followed from the S unit called ‘Particles at work’. This D unit provided enough material for eight double periods during a Further Science course and built on the content of the S units for Single Science. The teachers’ guide...

A Catalyst article about microwaves, infrared, ultraviolet and X-rays which are all electromagnetic waves. The article looks at their different uses and why some are used to create medical images and others to treat disease. The article also explores how the electromagnetic spectrum is used by medical physicists to...
