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.

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

• Recall that all living organisms need energy for life processes, which is provided by cellular respiration.
• Distinguish between cellular respiration and breathing, including the...

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...
