The equations of two intersecting lines are given. The challenge is to use Pythagoras’ theorem to show that the triangle formed by the lines and the y-axis is a right-angle. The point of intersection is determined by solving simultaneous equations.

Each example is derived from a pair of perpendicular lines....

In this activity, students synthesise prior learning about structure and bonding, and about enzymes, and apply it to a new context: X-ray crystallography. The main part of the activity involves students pitching for funding for new equipment – how will they use the...

In this teacher presentation and collection of student worksheets, the area of each face of a cuboid is given. Students are then asked to calculate the volume.

Each student worksheet contains a different cuboid, but the solutions all have something in common. The teacher presentations highlights two possible...

This resource, from the Royal Institution, provides students with the opportunity to explore the formation of a parabola through a paper folding activity. Students follow a set of simple instructions which describe how to fold a piece of A4 paper and are asked to describe what shape is produced. The activity is...

There are two parts to the DIY Dendrometer resources: 

Part A focusses on how trees grow and their role within both the carbon cycle and the water cycle. Learners are encouraged to take part in a citizen science project which involves creating and installing a DIY...

Activities in this resource aim to:

• celebrate the achievement of completing the Human Genome project in 2003
• show the relevance of genome sequencing today
• explain the methods used for DNA sequencing, including the illumina method of rapid sequencing and the shotgun sequencing
...

In this activity from ARKive, students look for similarities between the basic body plans of different vertebrates as evidence of evolutionary change. This customisable presentation builds the scientific explanation of natural selection by illustrating four key observations:

• All organisms produce more...

Using a spreadsheet as a grid of 'pixels', this computing activity teachers how 1's and 0's can store image data. The classroom exercises use images with increasing pixel resolution, looking at how this affects the clarity of the image. Moving from black-and-white images, the students then use grids of colour...

In this activity from the Institute of Engineering and Technology (IET) students perform calculations and apply formulae to a spreadsheet of data collected by a data logger, in order to determine how many visitors to an aquarium at any one time.

The resource includes a presentation and teacher guidance.

In this Science upd8 activity students take on the role of forensic science technicians who are acting as expert witnesses for the murder of Angel. Students analyse blood splatter patterns to check whether the murder weapon used was a hammer. They also watch a demonstration of a blood viscosity test to check...

In this ARKive activity, students research and design their own conservation programme to learn about the importance of biodiversity as well as the economic benefits and services ecosystems provide. Using examples of successful conservation programmes within the UK Overseas Territories, students learn about the...

This resource focusses on learners designing a robot to act as an assistant referee during a game of football on the Moon. They will consider the challenges associated with playing football on the Moon and the duties of an assistant referee. Students will produce a labelled sketch of their idea to meet a set of...
