This lesson is designed for the NEW AQA Trilogy Physics GCSE, particularly the 'Molecules & Matter ’ SoW.
 
This lesson begins with a definition of density as well as the calculation (and units) for density. Students can take notes using the PowerPoint presentation and then work through the worked example on the board, before the answer to this question is revealed. Students will now need to rearrange the equation in order to calculate either the mass of the object or the the volume of the object.
 
Students will now copy and complete a table on the different densities of materials, using the equations written in their books they will need to calculate the mass/volume/density of these materials. The mark scheme for this work is included in the PowerPoint presentation so students can self-assess their work once it is complete.
 
Students will now focus on the ‘Maths Skill’ of converting units into standard form, an example if first given to students before they work through a set of numbers - converting to standard form. Students can self-assess their work using the answers provided once this is complete.
 
Students will now work their way through a set of questions, some ‘exam-style questions’ on density. Students must show all their working, the mark scheme for these questions is included in the PowerPoint so students can self-assess their work once it is
complete.
 
The next part of the lesson demonstrates to pupils how they can work out the density of a solid object with an irregular shape, as well as the density of an unknown liquid. Students are shown the steps needed to calculate the density of these substances, they will then be given a set of problems to work through. Once complete students can self-assess their work using the mark scheme provided.
 
The final two tasks are firstly a past-paper exam question and then a ‘True or False’ activity - both to assess students knowledge of what they have learned this lesson.
