What research are scientists doing to help prevent the spread of this deadly disease? How is malaria normally transmitted to humans? What is unusual about this type of malaria (called Plasmodium knowlesi) being passed to humans? What other data would you need to look at? This type of malaria is transmitted by mosquitoes who have bitten infected macaques. Students must consider how drone photos, GPS tracking and interviewing local people could help answer the question. This activity illustrates how scientists use fieldwork to collect evidence. It includes materials for the lesson activity and teacher guidance, and supports students aged 14-18. It covers areas of science enquiry (Working Scientifically).
