In this activity, students create colour images from satellite data. This allows them to study how different surfaces reflect different wavelengths of light, how coloured images are created using an RGB model, and how band combinations can be chosen to examine a particular landscape effectively.

This lesson develops the concept of finding areas of sectors. In particular students will:

• Find perimeters, areas, and arc lengths of sectors using formulas
• Find the relationships between arc lengths, and areas of sectors after scaling
• Using radians

The initial challenge...

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

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...

This resource, from the University of Nottingham, describes a number of investigations which could be carried out in heathland habitats. Heathlands are excellent habitats to use for designing and carrying out experiments. Plants are often relatively easy to identify when compared with other habitats and...

The materials in this resource are from the Secondary National Strategy ‘Progressing to Level 6 and beyond in science’ project. They were intended for science teachers who are focusing on helping their students in developing skills in effective group talk.

This resource from the Institute of Physics, describes how electrocardiagrams (ECGs) record the activity of the heart through electrodes placed on a patient's skin. The teacher's notes contain an introduction to ECGs and lesson notes for the associated PowerPoint file. A mark scheme for the worksheet is also...

This activity requires students to calculate net income after tax and national insurance have been deducted. Students then are asked to discuss if the progressive taxation system is fair. Answers to each of the calculations are available.

The presentation shows how income tax and national insurance rates are...

This lesson develops concepts relating to radicals. In particular, students will enhance their understanding of:

• Use the properties of exponents, including rational exponents and manipulate algebraic statements involving radicals.
• Discriminate between equations and identities.
  In this...

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...

This challenge, from Practical Action, requires students to design and build a model structure that will enable farmers to grow crops even in an area that may become flooded. A floating garden, built on a base of aquatic weeds, is a low cost and sustainable way of allowing people to grow vegetables. The resource...

This resource suggests a number of investigations into bee behaviour which can be used to:

• develop an understanding of the interdependence of organisms in an ecosystem, including food webs and insect pollinated crops
• consider the importance of insect pollination in human food security
