In this lesson, students will be introduced to the advantages of big telescopes and the use of telescopes to do astronomy across the whole electromagnetic spectrum. They will then explore the transit method of detecting exoplanets (either practically, or using real astronomical data) and use mathematics to...

Produced by the Royal Observatory Greenwich, this booklet introduces the concepts of dark matter and dark energy and its role in the solar system. Included is an online video that discusses how the Universe will end. Equations and physical terms are introduced and discussed. Questions and answers are included that...

The ‘Experimenting with Industry’ series was published in the mid-1980s when it presented industry-related science practicals for schools. It was developed as part of a 'teachers into industry' project organised by The Association for Science Education (ASE) on behalf...

In this video independent and dependent variables are discussed, before experimenting with a trolley on an inclined ramp. The data is then graphed and analysed to investigate any relationship between ramp height and trolley speed. This is a GCSE Physics Practical.

There are teacher notes and student materials which describe the research into the potential effects of climate change on a Coralline algae species. Curriculum links include biodiversity, sampling techniques, student t test, Simpson’s Index, photosynthesis, climate...

ExperimentsAtSchool allows students to collect and analyse experimental data to draw practical conclusions in subjects including science, geography and psychology. Aimed at students aged 7 to 16, the experiments help them to develop and improve their data handling and statistical skills.

Each experiment has...

Produced by the Learning and Skills Improvement Service, this resource is a kinaesthetic activity in which students experience being part of a 'circuit'. A rope loop is passed around the group to represent the current flowing in a circuit. One student, the power supply, adds movement to the rope. The students see...

A Catalyst article about the hunt for an explanation of inheritance. The role of chromosomes was announced in 1903 and the structure of DNA was revealed in 1953, both of which were major scientific breakthroughs in this field of research. This article examines the history of inheritance.

This article is from...

This paper from the May 2016 Using STEM Research Conference looked at two research projects  which were intended to develop beginning and experienced teachers’ explanations in secondary science classrooms.

The first study involves beginning teachers and is focused on developing their understanding of what is...

Students observe what happens to blood added to salt solutions of different concentrations. This is done in test tubes, although it may also be possible to observe what happens under a microscope. The students record their observations and attempt to explain what has happened to the red blood cells. They then...

A Catalyst article about careers in geological exploration. The article contains a case study about an exploration geologist and looks at an undergraduate degree course in exploration geology.

This article is from Catalyst: GCSE Science Review 2007, Volume 17, Issue 4.
