Pupils line up outside in an orderly manner before entering the room. They enter the room, get out their equipment and books, bags are put under the table.

Manage entrance of pupils. Ensure seating plan is adhered to.

Register taken as soon as pupils are settled.

Have seating plan and register ready.

Starter: Magnifying glass

Have students use their lens with an object placed very close to the lens. Ask them to attempt to view the magnified image. In this position, the lens is acting as a magnifying glass, and the image is a virtual one so cannot be shown on a screen. Highlight the fundamental difference between this situation and the one they had previously when using a distant object to measure the focal length of a lens, where real images were focussed. Explain the concepts of real and virtual images.

Main:Students follow the instructions on Worksheet P1.3b. The range of data to be collected is found on Worksheet P1.3c. This sheet suggests a range of data that students may want to collect and then guides them through recording, considering their results, and evaluating their investigation. In this investigation it is important to emphasise the control variables i.e. object size and focal length.

As an extension activity you could ask students to hypothesise how the results might be similar or different if measuring the distance from lens to image compared with image height. They could also suggest an experimental method to test this hypothesis.
