Mosquitoes are the world’s most dangerous killer. The diseases they transmit, malaria, Zika and dengue fever, cause more than a million deaths per year. Some scientists have suggested exterminate all dangerous mosquito species. One method is to release genetically modified (GM) male mosquitoes which prevent further breeding. In this project, students investigate whether exterminating mosquitoes is a good […]
O mosquito pode ser um assassino perigoso. As doenças transmitidas por determinados mosquitos, Zika, Dengue, Chikungunya, Malária, causam mais de um milhão de mortes por ano. Alguns cientistas têm sugerido exterminar todas as espécies perigosas de mosquito. Um dos métodos utiliza mosquitos machos geneticamente modificados que interrompem o ciclo de reprodução. Neste projeto, os […]
The extraction of gas from shale rock – hydraulic fracturing, or fracking – is widespread in the USA. Whilst some countries in Europe have banned fracking following concerns that substances used in the process pollute water, others want to exploit shale gas reserves to provide new – and cheap – sources of natural gas. In […]
As people live longer the demand for new organs to replace failed ones increases. One possible solution is to build new organs in a dish from cells taken from the patient’s own body. Students use evidence from case studies to work out if this is possible and then to decide whether this new technology offers […]
The EU has recently imposed limits on the power ratings of vacuum cleaners, and further limits on other appliances could soon be in place. In this activity students consider a further (fictional) future restriction, on home electricity use. Students calculate the energy transferred daily by the appliances they use. They are then set the challenge […]
Imagine it is 2020 and students are about to get their first car. Increased carbon dioxide emissions have led to huge financial incentives to buy alternatives to petrol engines – but which car is best? In this activity students examine evidence and come to a decision on who wins the Car Wars. Learning objectives Apply knowledge […]
