KS3 ~ Year 8 - Energy Transfer: Radiation

This lesson is designed for the KS3 Year 8 Science course, specifically the P2 1.2 unit on ‘Energy’.

More Biology, Chemistry and Physics resources can be found in my TES Shop: https://www.tes.com/teaching-resources/shop/SWiftScience

This lesson starts with a task whereby students will watch a video on infrared radiation, they will need to try to come up with a definition for infrared radiation whilst watching. The answers that students come up with can then be marked and corrected using the answer provided.

Students will then be shown a diagram of a Leslie’s cube, and are told that different surfaces emit different amounts of infrared radiation. Students will then be asked to make a prediction about the surface they think (out of a choice of surfaces) will emit the most radiation.

Students will then complete an investigation into the amount of infrared radiation given off by different coloured tins - black or silver. Once complete, students can use the data they have collected to draw a graph of their results and complete the analysis questions.

Students will then be given examples of how infrared radiation can be absorbed and reflected and why these two processes are useful. Following on from this, students will complete a ‘fill-in-the-blank’ task to summarise what they have learned this lesson, this task can be self-assessed using the mark scheme provided.

The plenary task is a ‘pick a plenary’ task, students are asked to either summarise what they have learned in three sentences or write a definition for a list of key words provided.

All resources are included at the end of the presentation, thanks for looking, if you have any questions please let me know in the comments section and any feedback would be appreciated :)
