Different fuels are considered and how energy to move transport is released during combustion. This lesson also looks at the story of steam tube trains and our changing understanding of the effects of emissions from combustion on health.

Learning outcomes:

• Could represent combustion reactions...

With the increasing pressure of a growing human population it is becoming increasingly difficult to conserve natural habitats. Ultimately, not every green space can be afforded conservation protection. This field study encourages students to act as environmental scientists to compare different habitats and decide...

This Science upd8 activity draws on Titan which is the biggest of Saturn's moons.

There are two student activities; one involves labelling a diagram to tell students on Earth about the nature of Titan.

The other asks students to take the role of Titanian space explorers and use data to compare the...

Conditions on other planets are unlikely to be within the same ranges as that experienced by Earth. However, a degree of variance from ‘ideal’ ranges may be tolerable for a small number of organisms known as extremophiles. This investigation looks at the effects of subjecting a living organism (yeast) to some...

This Catalyst article explores the complex structure of cells, and numerous theories of how they were formed. It describes how the development of electron microscopes has allowed greater detail of cellular strutures and organelles to be understood. The article includes detailed electron micropgraphs, along with...

This worksheet in this resource introduces students to the topics of classification and binomial nomenclature. The idea of hierarchy is illustrated, before explaining Linnaeus’s system of classification and the terms kingdom, phylum, class, order, family, genus and species. There is also a useful introduction to...

This video uses two oppositely charged metal plates to demonstrate that a candle flame contains ions. Positive ions are attracted to the negative plate, while negative ions the positive plate. Even when the candle is extinguished, the smoke is attracted to both plates and so must also contain ions.

A multiple choice quiz on medicine for  AS/A level chemistry.

Although it is written for OCR AS/A level chemistry (Salters) H033/H433 course, it can be edited to suit your scheme of work.

A mince pie company wants to improve their festive mince pie recipe and to do this they need to know what their competitors have in their mixtures that make them taste so good.

Children are tasked with separating, grouping and identifying the ingredients in mince pies to find out what makes the perfect pie....

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

• Identify the types of things rock may be comprised of.
• Describe the differences between grains, fossil fragments and crystals found in rocks.    
• Explain how the types of...

These student handouts contain text and questions about:

• Classifi...

Our height changes throughout the day. When we lie down at night, gravity no longer pulls in a direction to make us shorter, so our bodies stretch, and we return to our taller height again. However, astronauts who don’t experience the effect of gravity for months at a time grow taller.

In this activity...

A Catalyst article about the naming system used for biological species, devised by Linnaeus. The purpose of biological names is investigated and the article also explains how the naming system works.

This article is from Catalyst: Secondary Science Review 2009, Volume 19, Issue 3.
