This is a 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 legacy GCSE 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. A premium editable version of this is available at: https://www.tes.com/teaching-resource/-11858631 Keywords: energy, transfer, food chain, efficiency

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 a non-editable resource. A premium editable version is also available at: https://www.tes.com/teaching-resource/resource-11858634 Key words: greenhouse effect, atmosphere, CO2, carbon dioxide, global warming

This worksheet is useful for student to summarise information about the EM Spectrum, It can be used as an information gathering tool or to sum up key points about the spectrum. It could also be used for independent learning in school. It goes well with the activity EM Spectrum sort cards. There are three slightly different sheets that increase in demand from (1) to (3). This resource is part of a sequence with the following three other resources: This resource EM spectrum sort cards https://www.tes.com/teaching-resource/resource-6341302 IR remote control https://www.tes.com/teaching-resource/resource-12952897 UV Washing powder https://www.tes.com/teaching-resource/resource-12952892

This is a short standalone activity, good for developing higher order thinking skills and providing an opportunity for cognitive conflict and discussion. Firstly either allow the students to work through the first two set of tasks sequentially. Alternatively, one half of class can be given first sheet,marked with a triangle, the other half being given the ones marked with a square to be worked on independently. After a few mins pair up with third sheet. Students respond well to even quite tricky questions.

This resource is to help learners either learn or revise the sequence of events in generating electricity for consumers. The statements on the card are partial statements about what happens during this sequence. Learners could try sorting these as a prediction of the sequence. This allows for discussion & cognitive conflict. Students could justify their reasoning, complete the statements and/or sequence by indicating what is being referred to at each stage, compare similarities é differences é highlight differences in other power stations e.g. nuclear. Jumbled é non-jumbled versions included.

Keywords: circuit, model, current, charge, electron, hats This is an engaging model for students to participate in modelling electric circuits. It is aimed at KS3, but has been used successfully with KS4 and KS5. It helps students build a coherent model to explain circuits, although alternative models help explain energy transfers and potential difference (voltage) better. Please note that this was originally published a number of years ago as part of the North Yorkshire Success for All project. A premium PowerPoint slideshow that provides a visual model of the motion of charges in the circuit is also available at https://www.tes.com/teaching-resource/resource-12613884

Keywords: Efficiency, calculation, graph, skill, explain, justify, MAT. This activity is designed to stretch the most able learners with some questions and tasks related to calculating efficiency. There are some demanding questions involving handling data and using graphs to make predictions. This was designed as a home learning task to consolidate learning about efficiency. It would also make a suitable starter for AS/A level. An answer sheet is included with suggested marks for each question.

This activity comprises of an interactive spreadsheet model that allows you to change the value in the yellow coloured cell to represent a percentage of noise added to a signal. It allows you to see what happens to both analogue and digital signals with the same amount of noise side by side. There is a worksheet to summarise the difference between the two kinds of signal and also an activity for pupils where they plot out signal plus noise by hand - ideal for a flipped learning approach where pupils do this in advance of the lesson before discussion in the lesson.

These flashcards, when printed out back-to-back and then cut out will produce a series of double sided flashcards showing the composition of particles in the standard model. They are good as an independent learning tool or revision activity. They could be used in preparation for the 'Identify the particle rolling slideshow Instant Engagement / Retrieval - available on TES Resources at: https://www.tes.com/teaching-resource/resource-6341196

These sort cards can be used as a starter or starting point for the topic of the EM spectrum and again as a review/ plenary. They can also be used to help revise the sequence of the EM spectrum. This activity goes well with the EM grid activity. This resource is part of a sequence with the following three other resources: This resource EM spectrum sort cards https://www.tes.com/teaching-resource/resource-6341302 IR remote control https://www.tes.com/teaching-resource/resource-12952897 UV Washing powder https://www.tes.com/teaching-resource/resource-12952892

Keywords: digital, analogue, encode, decode. Notes: This activity helps learners compare how a simple string telephone works against a more complex digital system. Get the students to make string telephones using paper/plastic cups and lengths of string before attempting to complete the sheet. This helps explain an abstract idea by building up from a very hands on simple (more concrete) example. It really engages learners of all abilities. There is an activity sheet and a guidance sheet with answers. This was originally designed for OCR 21st Century Science unit P2

This is a small collection of key words related to data handling. They are designed as a display tool. Remember if laminating to use matt laminates for wall displays to avoid reflection problems. Key words: range, mean, true value, average, real difference.

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 resource is a collection of 6 slightly different see-saw balances that can be used with learners to help them develop the skills to weigh up an argument. The idea is that students will list reasons on both side of an argument (e.g. Should we have Nuclear Power?). They then use this to help make a decision. The scoring column on some sheets allows learners to score each argument out of a maximum of say 3. Add the scores on each side to see which has the stronger argument. This also includes phrases to support a more detailed conclusion. This was inspired by 21st Century Science.

There are two parts to this activity, one is a practical activity to model the process of digestion. The other is a powerpoint slideshow to show what happens to the food on its journey through the body. If using with KS3 then the learning outcomes on the activity plan could also include breaking up of molecules in digestion. If using with KS2 for the new curriculum, the powerpoint will include some terms/slides that you may wish to miss out, so it has been left in an editable form.\nPlease ensure that you carry out a risk assessment before carrying out a practical activity.

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 P2, although could be used with other exam boards.\nClicking through the show reveals answers one a time. These reduce to A5 easily, the ideal size for most pupils. Please note grades are approximate.

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 prefix that represents the power of ten multiplier. 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.
