Description
General aims:
- to learn about the reflection of light
- to be able to interpret natural phenomena
- Explain the law of light reflection.
- introducewith the rules of drawing an image in a flat mirror
and image properties.
- To tell how mirrors appeared in the world and in Lithuania.
- Explain the main concepts that describe lenses:
• concave, convex mirrors;
• focal length of mirror
• main mirror focus, center of curvature, principal axis
• application of concave and convex mirrors;
- to acquaint with the course of reflection of rays of light from a concave and convex mirror
- to know the language associated with light and mirrors
- to develop positive learning habits such as organisational and problem-solving skills.
Linguistic aims:
- to read English with ease
- to understand content
- to learn from written texts
- to express opinion
- to enable students to understand topic correctly
- to develop academic language
- to translate words connected with reflection in English into the mother tongue using their own words.
Subject specific aims:
- to familiarize students with the topic of light, mirror, application of mirrors
Target group age:
The web sites is aimed at 15 – 16 year old students. This web sites and virtual experiment can be used by anyone who wants to broaden their knowledge of physical properties of light, mirrors. Also, the resource is recommended to teachers who want to teach probability using English.
Level of competence in English (CEFR)
A2/B1
Time required to use the resource with the students:
The web sites contains 6 more short chapters so it is recommended to use the resource during 2 lessons.
How to use it
The teacher should ask the students to read about the light reflection at textbook at home before the lesson and then do the proposed project in order to enable students to use the required knowledge in practice. The students might get the answers and feedback at the end of the book.
Possible difficulties for the students
Students whose level of English is poor might have problems with understanding the content.

Comments
Reflection, and description is an interesting self-directed learning resource. It is available on https://www.khanacademy.org/ website for free. The resource can be used by teachers as an introduction to the topic of reflection of light or it might be assigned to students as a self-studying resource. The main strength of the video is clear explanations, lots of visuals and real-life examples. The resource contains a glossary with the most important vocabulary, which will allow students to practice the new terms. In my opinion, this web sites and virtual experiment (on related simulation lessons) is scientifically reliable and can be recommended to students and teachers as it is a very useful resource. In experiment is possibility to get distance between object and image.
