Experiment - melting ice & freezing wax
In this video, which is aimed at KS3 pupils, a video is shown with changes of state of matter for ice and wax.
The melting ice takes place on a two surfaces, a conductive surface (aluminium pan) and and an insulating surface (wooden chopping board). The video shows how the time of melting differs for each surface.
The experiment also shows wax freezing on the same two surfaces.
Pupils can compare the times and suggest explanations as to why the times differ. The video includes prompts to support their thinking.

Thinking About: A hot-air balloon rising
In this video, which is aimed at KS3/4 pupils, a hot air balloon is shown rising. Pupils are asked to describe and explain what they see and are reminded that there is a heater in the balloon. This can be used as part of a lesson about density, where pupils can use the idea of the hot air being less dense than the cooler air around it, therefore causing the balloon to float.

Experiment: Tangerine mystery
In this video, which is aimed at pupils in KS4, a tangerine is shown. Firstly it is weighed, then is shown floating on water. Then it is peeled, weighed again, and then pupils are asked to predict what will happen when it is placed in water. There is an element of surprise in the video that aims to help challenge preconceptions that they might hold.

Experiment: Making a fruit 'battery'
In this video, which is aimed at KS3/4 pupils, a fruit ‘battery’ is shown. The ‘battery’ has been made with different pairs of metals for the electrodes. Readings are shown in the video for the potential difference (voltage) across the electrodes for each pair. Pupils can then consider the connection between reactivity of the metals and the results of the experiment.

James Hutton & Deep Time - graded questions
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 OCR 21st Century Science Specification, although could be used with other exam boards.
Clicking through the show reveals answers one a time. There are two slightly different activity sheets for differentiation - one has key words, the other without. These reduce to A5 easily, the ideal size for most pupils. Please note grades are approximate.

Maths Skills - Units - SI Units Starter
These are a sequence of powerpoint shows designed as an instant engagement task (rolling on screen as learners enter the room for immediate engagement with learning). Learners write down the the SI units for the named quantity. More able learners could provide SI units in terms of fundamental base units. They are essentially the same task (with rearranged slides) but get progressively more demanding (as the changeover of slide gets faster) as the numbers in brackets increase. Start the students with (1) and then as they get faster, use the more demanding versions

Do Try This At Home: Modelling a 'day' - daytime and night-time
This is a video to support the teaching of space to KS2 pupils. In the video, it describes how you can model daytime and night time to help pupils understand that this is caused by the rotation of the Earth. It also explains the changes that happen during the seasons.

Video Experiment: A pair of forcemeters
In this video, you will see an experiment where a pair of identical forcemeters are pulled apart. There are questions that focus pupils on the force pair interaction. It asks pupils to make predictions, then shows what happens in the experiment.

Models of the atom - Comparison
This activity aims to clarify thinking around the models of the atom that scientists use, and why we have more than one model.
A slideshow that compares different models of the atom, the timeline of discovery and summarises the uses of each model.
Key words: Model, Plum-pudding, Rutherford, Dalton, nuclear.

P2 Images, compression and file size
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.
