This activity involves looking at reliability of information found on the internet and encourages students to evaluate this critically in light of the discovery of new information. Students really do engage with the activity and find it a useful learning experience. An activity sheet and guidance sheet are included. Please note that the resource points to two external websites which I acknowledge as external sources of information and as such cannot be held responsible for the content of these websites. It is recommended that these are checked fully before use.

This resource is a short powerpoint show and a pdf of the first slide. The idea is that learners read the URLs for a series of websites and decide whether they are trustworthy. They could put them into one of say three categories (e.g. High, Medium. Low).This is great for stimulating debate amongst learners, especially if the task is completed as a group. It is very effective when learners are asked to explain their reasoning. The powerpoint show can then be used to develop understanding further.

Keywords: Image, quality, file size, download time, compression A series of activities that use a familiar image to get across the relationship between file size and image quality. It also supports learners to consider the effect of compression on image quality. It was intended to use the powerpoint show as a starter and follow it up with the file size worksheet, then the compression worksheet. Originally designed for unit P2 of 21st Century Science.
