This Science upd8 resource focuses on the chemical PFOA (perflurooctanoic acid), which is used in Teflon manufacture and is reportedly linked with an increase in the risk of developing allergies. In this activity students examine some of the evidence surrounding PFOA and consider a range of viewpoints.
This Science upd8 activity draws on a recent Government warning about poisonous mercury from low energy light bulbs being a risk to users. But is this risk worth the benefits of using low energy light bulbs? In this activity students rank risks and benefits to help them decide.
In this Science upd8 activity students use chemical techniques and reactions to investigate a crime scene. Students learn about the particle model to solve a crime that has been committed in an art gallery. They compare ways to show fingerprints including using the sublimation of iodine.
This Science upd8 activity is inspired by the film Pirates of the Caribbean. What are the contents of the treasure chest? What metal is the key made of? What happened to the treasure after decades under the sea?
In this Science upd8 activity students perform a CSI investigation to find the murderer in the park on Guy Fawkes' Night. They encounter a variety of science on the way, from rocket science to electron energy levels. They learn how those colour-giving electrons that make fireworks so much fun, fit into the atoms that make…
This Science upd8 activity draws on Titan which is the biggest of Saturn's moons. There are two student activities; one involves labelling a diagram to tell students on Earth about the nature of Titan. The other asks students to take the role of Titanian space explorers and use data to compare the solids, liquids and gases on…
Can we solve the problem of summer water shortages by making rain? In this Science upd8 activity students learn about the significance of droplet size in natural rain formation. They then look at Chinese experiences of 'cloud seeding' before annotating a graphic to show how it works.
This Science upd8 resource draws on cyclone Sidr which hit Bangladesh in November 2007. Millions were left homeless and 3,000 people were killed. The activity asks students to look at how cyclones happen and addresses the common misconception that air is 'nothing' and weightless.
This resource from Science upd8 revolves around the subject of kidney stones. Dehydration can cause excruciating pain from kidney stones. This activity stimulates discussion through a stunning image of a vicious-looking kidney stone. Students apply their knowledge of saturated solutions and crystallisation to find out how it formed.
In this Science upd8 resource students take on the role of a marketeer trying to sell a new instant ice-cream vending machine. They use PowerPoint’s simple animation features and a gallery of images to explain the science behind the process of mixing flavours and quick freezing.
This Science upd8 activity focuses on sulphur, which is usually the element fingered for the blame when it comes to pollution. Students research sulphur to get the low down on this "Jekyll and Hyde" chemical; then act out a trial of the suspect element.
