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.

This activity contains a powerpoint with graded questions & answers and matching pupil activity sheets, designed to be used at the end of a lesson and/or the start of the next lesson to review previous learning. The questions are based on the previous OCR 21st Century Science Specification unit P3, although could be used with other exam boards. Clicking through the show reveals answers one a time. These reduce to A5 easily, the ideal size for most pupils. Please note grades are approximate.

Keywords: p.d., voltage, potential difference, frequency, time period, time base, measurement This resource has a powerpoint show with worked examples of how to calculate p.d., frequency etc. using an oscilloscope. It is supported by graded intended learning outcomes and an independent learning task, which set as home learning has resulted in students being extremely creative.

This activity helps learners ‘draw the meaning’ of key words to do with light/radiation. It tests what learners think these words mean and builds an understanding of the concept behind each word. Two slightly different versions - one adds the word ‘emit’. Great as an instant engagement starter (on a sheet on the desk and shown on screen on entry to the room) to a lesson where these ideas will be explored. Also helpful for GCSE students recapping ideas before applying them in a context such as the greenhouse effect. Right click the web links to download the powerpoint shows.

This resource is an was originally designed for instant engagement, to be on display on entry to the room. The students are given a period of time (say 3 minutes) to rank order the sources of information. This works well in groups with mini-whiteboards. The teacher then asks students to indicate whether each source was in the top 3, middle 3 or bottom 3 – e.g. by show of hands. This supports a discussion on reliability and disagreement between groups provides chance for cognitive conflict and students explaining their reasoning. It was originally designed as a starter to LSS activity 3.1

This is a collection of resources that would work well as a lesson. A lesson outline is provided showing how the resources might be used together. There is an email designed to set the scene and for use as as a ‘hook’. There are also sheets for learners to summarise their learning (tweet). You may want to supplement the resources with pictures of a woolly mammoth (link only due to copyright restrctions) and video ‘footage’ e.g from Ice Age movie. This was designed as lesson for a KS3 nurture group although would be suitable for KS2 or other KS3 groups with adaptation. Please note that this is a non-editable version. A fully editable premium version is also available.
