Science / Technology lesson
Intermediate level
Description
Materials
Main Aims
-
To provide practice of science / technology vocabulary
Subsidiary Aims
-
To provide gist, scan, inference and summarizing sub skills using a text about a camera that can catch cancer , another text about the drawbacks of genetic engineering on food and a third text about the long-term threats of the mobile phone to health .
Procedure (31-39 minutes)
To use visuals to introduce the topic of science and technology . Then draw two spidergrams one about science and the other about technology . Students (divided into two groups , one to brainstorm words about science and the other about technology .
A : Students try to predict the content of texts from three headlines : 1- Camera that can catch cancer 2- The genetically modified pea that causes allergies 3- Mobile phone safe B : Students skim the texts and match the headlines with the texts
Students are divided into three groups to correct some false statements with details from the texts : G1-text A : a/ Has it been proved that mobile phones can cause brain cancer ? / justifiy b/ What resultats have scientists found ? c/ Does it mean that mobile phones are safe ? d/ How long could it take to prove that ? G2-text B : a/ what are the benefits of high-tech camera ? b/ What is the advantage of this ? c/ How long has the camera taken to be developed and used ? d/ How can hospitals benefit from it ? G3-text C : a/ Why has the project been abondned after ten years of study ? b/ what experiment was carried out to prove its inefficiency ? c/ What were the results ? d/ What do they prove ?
To complete 3 gapped texts with words from the texts . Extract 1 : Scientists dismissed people´s fears that mobile phones can ............. brain cancer ; nevertheless they haven´t ............ the possible ............. that the use of the mobile might cause . Extract 2 : Thanks to the hi-tech camera, doctors can now ..............malignant melanoma which is the .......... from skin to cancer . The earlier the disease is diagnosed , the easier it can be ............. . Extract 3 : Genetic modification applied to food may have ................ ............. for example the genetically-modified pea caused ............. when fed to mice , as it affected their ................ Speaking activity : what conclusion can you draw ?
