Manipulating digital images
Lesson details
Learning outcome
I can use graphics software to edit and manipulate digital images.
Key learning points
- Basic image editing with software can be combined to solve complex problems requiring image manipulation.
- Digital manipulation provides creative benefits but also ethical drawbacks.
Keywords
Scale - changing the width and height of the image in pixels
Prompt - the text description you give to the AI tool to tell it what kind of image you want it to create
Filter - a tool or effect that can be applied to an image to change its appearance
Common misconception
Generative AI always has a negative affect on society.
Generative AI isn't always negative; it depends on its use. Generative AI tools can help artists, educators and scientists create innovative designs, engaging learning materials and advanced simulations.
Teacher tip
Show both positive and negative uses of AI. Discuss its benefits, risks and ethical concerns to help students develop critical thinking and a balanced perspective on AI.
Equipment
Pupils will need access to a device that has graphic editing software. Examples in this lesson use GIMP https://oak.link/gimp

The starter quiz will activate and check your pupils' prior knowledge, with versions available both with and without answers in PDF format.
We use learning cycles to break down learning into key concepts or ideas linked to the learning outcome. Each learning cycle features explanations with checks for understanding and practice tasks with feedback. All of this is found in our slide decks, ready for you to download and edit. The practice tasks are also available as printable worksheets and some lessons have additional materials with extra material you might need for teaching the lesson.
The assessment exit quiz will test your pupils' understanding of the key learning points.
Our video is a tool for planning, showing how other teachers might teach the lesson, offering helpful tips, modelled explanations and inspiration for your own delivery in the classroom. Plus, you can set it as homework or revision for pupils and keep their learning on track by sharing an online pupil version of this lesson.
