Plastics and Polymers *suitable for home teaching*

This film, from Twig World, looks at how plastics are made and how they can be manipulated to have very different functions. The key points made in the film are: •Plastics are synthetic materials called polymers. •Polymers are made of small molecules called monomers obtained from crude oil. •The plastic's...

Invention of Nylon *suitable for home teaching*

This film, from Twig World, looks at what makes the polymer Nylon so durable. The key points made in the film are: •In the past, clothes were all made from natural sources, such as silk, wool and cotton. •Then Wallace Carothers discovered nylon in 1939. •It was discovered through experimentation with polymers,...

Plankton and Global Warming *suitable for home teaching*

This Cape Farewell video clip features a discussion about the three important carbon cycles at work in the oceans and their place in global warming.

In Activity I - Carbon cycle, students use the video to build up diagrams of the three carbon cycles. Teachers can use the carbon cycle sequence images to...

Pixel Perfection

This investigation from Cre8ate maths involves students in finding the best size screen for a television. If you have a large flat screen and view a standard analogue or digital picture the individual pixels are visible if you are sitting too close to the screen. Working in small groups of 3 or 4, students measure...

Hip Stars

Scientists at the University of Oxford are investigating the link between sporting activity in young people and the development of osteoarthritis. In very active people, bony lesions can form on the hip joint which increases their risk of developing the condition.

In this activity students apply what they...

Perfect properties

The development of the jet engine is engineering at its most extreme. In this activity, students analyse data to choose materials with suitable properties for different parts of the jet engine.  

Learning Outcome

  • Students learn how to analyse data on material properties to...

MRI brain briefing

In this activity, student groups become multidisciplinary teams of hospital staff working on new leaflets or videos to help patients prepare for MRI brain scans.  Through the activity, students enrich their understanding of the brain as an organ, and apply their knowledge of magnetic fields and the magnetic effects...

Fossil findings

This activity is based on the work being carried out at The University of Oxford where researchers are using x-ray tomography (CT scanning) to visualise and measure the 3D structures of fossilised organisms that are still encased in rock.

Students will classify modern day vertebrates before repeating with...

Cool blades

In this activity, students learn about heat transfer from jet engine turbine blades. The blades reach temperatures as high as 1000 ºC. How do the blades cool, and how do scientists measure the rate of cooling at such high temperatures?

Learning Outcome

  • Students learn how to...

Carnivorous Plants

This film, from Twig World, looks at how some carnivorous plants trap and kill their prey. The key points in the film are:

•Some plants, often in harsh conditions, have adapted to catch prey.

•They lure small insects with sweet nectar and bright colours.

•They capture them in sticky pads and...
