Description
General aims
Students will be able to explain how the human eye produces images of distant and nearby objects and will investigate some of the common vision problems. They will focus on the physics of sight. They will acquire the basic English vocabulary connected with the topic (lenses). Students will develop positive learning habits such as organisational and problem-solving.
Linguistic aims
Students will be able to:
- read English texts with ease
- reflect on their reading experience and share it with their peers
- get the main ideas from a text
- comprehend the topic correctly
- translate words connected with the topic (greenhouse effect) from English into their mother tongue.
Subject specific aims
Students will be able to:
explain how the human eye produces images of distant and nearby objects Target groups age:
Students from high school 17-18+ years old. What is more, this web site can be used by anyone who wants to do extend knowledge about lenses.
Level of competence in English (CEFR)
B2
Time required to use the resource with the students: 1 hour

How to use it
The teacher will set the class into three groups and assign one text to each group: the anatomy of the eye (https://www.physicsclassroom.com/class/refrn/Lesson-6/The-Anatomy-of-the-Eye), Farsightedness and its Correction (https://www.physicsclassroom.com/class/refrn/Lesson-6/Farsightedness-and-its-Correction) and Nearsightedness and its correction (https://www.physicsclassroom.com/class/refrn/Lesson-6/Nearsightedness-and-its-Correction). Students read the text individually and take notes on the asigned issues. They discuss their findings in their group and then they have to present the notes to the rest of the class and use the photos provided by the site to explain their part/section of the process.
The teacher highlights some new words for students in English and students should provide the translation these words into the mother tongue and write down the new words in English in the notebook with the right translation.
Possible difficulties for the students
Students who have poor knowledge of English can have problems with understanding the content.

Comments
The texts are well organised and structured and are accompanied by illustrative pictures. However, they are complex and detailed. Therefore, the activity is suitable for students who are interested in studying medicine or any related field. In order for the students to get engaged in the reading and writing tasks the teacher should start by eliciting the vocabulary students know related to the topic (mind mapping tools such as x-mind.net could be used) . Students can also be asked to complete a KWL (Know, Want to know/Learned) table at the beginning and end of the class. Some students may need more guidance than others and may have problems with the language. Pair work or group work may make some students feel more comfortable. Students can also revisit the texts at home at their own pace.
