KS3 ~ Year 7 ~ More Changes of State

This lesson is designed for the Activate KS3 Science Course, specifically Year 7 C1.1 ’Particles & their Behaviour’

For more lessons designed for KS3 and KS4 please visit my shop at: https://www.tes.com/teaching-resources/shop/SWiftScience.

Students will firstly watch a video on the changes of state, this outlines processes students have covered in previous lessons as well as new processes such as evaporation, condensation and sublimation. Whilst watching the video, students will need to answer a set of questions, this work can then be self-assessed using the mark scheme provided.

Students will now need to copy and complete a diagram to demonstrate the changes of state which occur between solids, liquids and gases. This work can be assessed using the mark scheme provided once it is complete.

Students are now given an explanation of evaporation using the particle model, students can take notes on this process - including a particle diagram to depict the process. After this students are given a set of statements which either describe the process of boiling or the process of evaporation, students should sort these statements into the correct columns. The answers for this task are included on the PowerPoint for students to assess their work.

Students will now be asked to ‘Think > Pair > Share’ their ideas on the factors which could affect the rate of evaporation. Once students have had a chance to discuss their thoughts, they should feed back to the class before the answers are revealed.

Lastly is a ‘true or false’ assessment task, students need to read the statements and decide whether they are true or false. This work can be assessed using the mark scheme provided.

The plenary requires students to spend a minute talking to the person next to them about what they have learned this lesson.

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 :)
