Always another way

We would advise you to complete this lesson on a desktop device as you need to download and interact with additional files as part of the learning. These can be downloaded from the last slide of the worksheet. You should always ask your parent or carer for permission before downloading files from the internet. Learners will be introduced to alternative (symbolic) representations for images and sound, such as vector graphics and MIDI music. They will also be introduced to what compression is and why it is necessary.
