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.

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.

This activity follows on well from the Greenhouse effect starter. Based on interpreting data about planets in the solar system, it leads learners to the conclusion that Venus is hotter than it should be due to CO2. There are two levels of activity, the more demanding one explores the role of photons/light/radiation in heating planets. This activity was originally designed for 21st Century Science unit P2. Please note that this is an editable resource. Key words: greenhouse effect, atmosphere, CO2, carbon dioxide, global warming

This is an editable worksheet based activity that includes some higher order thinking to explore the ideas around energy transfer in simple food chains. Two versions are included, one with revised GCSE (1-9) grades, the other without. (please note that grade indications are only approximate). Why not try getting learners to choose a selection of questions to answer (e.g. do Q1-4 or Q3-8) An answer sheet is included. This resource was originally designed for OCR 21st Century Science unit B3, but still applies across a range of exam specifications. Keywords: energy, transfer, food chain, efficiency

This is a video aimed at pupils in KS3/4 that shows an experiment of a rubber band being stretched. The stretching happens when masses are added to the end of the band. There is an introduction the experiment, which aims to help pupils understand the most important ideas. After each mass is added the rubber band, the video zooms in on the scale to allow pupils to read this. This can form the basis of a graphing activity to find the relationship between the masses added and the extension of the rubber band. Unlike the linear relationship of the spring, there are some differences in the way the band extends, particularly towards the start and end of the experiment. There is a PowerPoint slideshow to help focus the activity if used in a classroom. This resource forms part of a sequence with two other resources: https://www.tes.com/teaching-resource/experiment-measuring-the-weight-of-masses-12952546 https://www.tes.com/teaching-resource/experiment-stretching-a-metal-spring-12952559 This resource

This video is aimed at pupils at KS3/4. It shows a video of an experiment where 100g masses are put onto a forcemeter, calibrated in newtons. It allows the measurement of the force for each mass. There are questions to focus pupils on the relationship between the masses and the weight. It can be used as a graphing exercise to calculate the value of the constant ‘g’.

This video is aimed at pupils in KS4 and students in KS5. It shows a model flying bat, attached by a string to a point, flying in a circle. The video poses questions about the motion of the bat and the forces, including the centripetal force, involved in the motion. The activity includes a PowerPoint slideshow with questions and answers.

This resource is an interactive slideshow aimed at pupils in KS3/4. It shows the screen of an oscilloscope with different waveforms of sounds. Embedded in the slideshow are sounds that would produce that waveform, so that pupils can hear the sound and see the waveform at the same time. There are slides that show the relationship between the waveform and the sound. There are also questions at the end that can be used to check that pupils can recall and understand the relationship between the waveform and the sound. There are worksheets included that can be printed on A4 and included in booklets or pasted into larger books. The worksheets can also be easily cut or folded in half for pupils using smaller books.

This activity is aimed at KS1 learners exploring seasonal change. Due to the nature of seasonal change, the suggested activity is intended to be run over a long period of time (up to one year).

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.

This activity allows students to indicate their perceptions on a particular question. The question might be a debate e.g. ‘Should we build more nuclear power stations?’, ‘Is cloning a good idea?’ or ‘Should social media be banned?’. To use the cards, print and laminate the cards. Lay the cards out along a line and ask the students to stand near the card that represents how strongly they agree (not on the card due to risk of slipping). Then ask them to justify their reasoning. This works really well when carried out before and after a debate. Designed for use in science, these also have use in other subjects such as Citizenship, PSHE and RE. Inspired by an activity at the NCT.
