Genetic Modification of Plants and Food Security

Produced in 2015, these resources look specifically at how genes can be altered in plants and how bacteria are central to genetic engineering techniques. Genetically modified (GM) crops offer the potential to help improve food security though this still remains controversial in some areas.

Networks

This series of five one-hour lessons covers computer networks at secondary-school level. The objectives of the lessons are: *Describe what a network is, the difference between a LAN and a WAN and identify three network topologies. *Describe pieces of hardware that are needed in a network. *Explain what an IP...

X-ray Imaging

This resource from the Institute of Physics (IOP), describes how X-rays can be used to image the body. The X-rays video, taken from an IOP Schools and Colleges lecture, describes how Roentgen discovered how to image using X-rays, in his lab. The lecture also describes how barium and iodine can be used to to image...

Magnetic Resonance Imaging (MRI)

This resource from the Institute of Physics (IOP), describes magnetic resonance imaging (MRI) of the body. The magnetic resonance imaging video, taken from an IOP Schools and Colleges lecture, uses analogies with sound to describe how the resonant frequencies of protons within the body can be used to produce...

Positron Emission Tomography (PET)

This resource from the Institute of Physics (IOP) includes information and activities related to Positron Emission Tomography (PET). The video describes how annihilation of electrons and positrons can be used to produce X-rays and image the body to find cancers. The teachers' notes contain an introduction to PET...

Gamma Cameras

This resource from the Institute of Physics (IOP), describes how cameras sensitive to gamma radiation can be used to image the body. The video, taken from an IOP Schools and Colleges lecture, briefly describes the history of the discovery of radioactivity and how the first particle accelerators could be used to...

Electrocardiagrams

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...

Pulse Oximeters

This resource from the Institute of Physics (IOP), describes how light can be used in pulse oximetry to measure pulse rate and oxygen levels in the body. The video, taken from an IOP Schools and Colleges lecture, describes how shining red and infra-red light through the body can be used to measure pulse rate and...

Body surface area

This resource introduces the formulae for the surface areas of cylinders, cones and spheres. Students are asked to use these to model parts of the body and calculate an estimate of their own body's surface area. Two formulae used in medicine for...

DNA and Genome Sequencing

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
  • ...
