This worksheet can be used at the end of a lesson about the frequency ranges of sound, as a long pre-plenary(!) After students have been taught about the human listening range and the frequency boundaries for ultra and infra sounds, they can enhance and the tutor can assess their understanding. It includes also some "extension" questions for the quick students. (It looks better in colour) Viktoria Tsakyri

This 12 slide power point presentation includes: 1. starter to introduce the difference between mass and weight 2. differentiated learning outcomes 3. relation between mass and weight and assessment questions 4. two problems to practice and extension question 5. description of terminal velocity 6. Worksheet to complete with differentiated tasks (it is the last slide which should be printed off separately and distributed at this point of the lesson) 7. plenary including 5 true false questions Viktoria Tsakyri

Students are asked to identify the appropriate resources for each picture. The task requires recalling the basic renewable resources but also develops critical thinking as a combination of resources could be the answer. By the extension, the task becomes differentiated as the students are asked to explain their choice in detail. It can be used as a starter or plenary. Viktoria Tsakyri

This 2 page worksheet can help the students work on calculations and graphs on thermal decomposition after the process is presented and explained. It can be used also in the case that a real practical is not possible (i.e. very misbehaving group or low ability one). Viktoria Tsakyri

This page includes 4 tasks which can be used as mini plenaries through out a lesson on lenses. 1. students identify lenses in everyday uses 2. students try to describe a lens (suggestion: the teacher may give some hints and give the definition afterwords so that the students can mark themselves) 3. students identify the main key terms on a lens 4. after a short practical (moving lenses and observing the changes of the image), students may conclude about the main factors affecting the focal length and the magnification Viktoria Tsakyri

15 slides of power point lesson presentation including: 1. L. Objectives and L. Outcomes 2. starter for introducing the concept of resistance with assessment questions 3. cartoon diagram to make clear Ohm's law with assessment questions 4. Ohm's law formula and explanation 5. practical instructions for the investigation of Ohm's law (depending on thelevel of the group, the practical may require a separate lesson) 6. 4 last slides with simple applications to check understanding Viktoria Tsakyri

The two slides include detailed instructions for the creation of a poster describing methods of reducing the energy used in a house. The questions to be answered are differentiated so the teacher can easily assess and grade each poster. The second slide shows how the poster should look like to guide the students. It is suggested to print out the two slides (preferably in colour) and distribute them to pairs. In the case of a low ability group you can use two 1 hour sessions (1st for the web search and 2nd for the creation of the poster and answering the questions). Viktoria Tsakyri

This 1 page worksheet can be used in introductory lessons about ionising radiation. It is split in 3 parts following the route of the lesson with rising difficulty. It can be used at the end of the lesson or each part can be used as mini plenary/assessment during the lesson. Viktoria Tsakyri

This worksheet can be used as a quick plenary or starter to check the understanding of the difference between Darwin's and Lamarck's theories. The students should simply note if each frame is true or false and as an extension they should write an explanation for their answer. To save paper (!), the page contains the worksheet two times. It looks a lot better if you print it in colour! Viktoria Tsakyri

The worksheet includes questions for the EM spectrum. For part 1, students may use a diagram of the EM spectrum, or not if they are of higher level. Part 2 can be used as a plenary. Viktoria Tsakyri

This 19 slide power point includes: 1. Differentiated learning outcomes 2. Starter activity. Slide 2 without any hints, slide 3 with hints for lower level group/students. (You may also print out and distribute) 3. Slides 4,5,6, identifying forces and their effect 4. Slide 7, description/example of 1 Newton feeling. 5. Slides 8-13, recalling friction and air resistance, their effects and the factors they depend on. The slides include mini tasks to assess the students. 6. Slides 14-16, 3rd Newton's law, including examples and tasks. 7. Slides 17, 18, true/false plenary 8. Slide 19 is a 2 part worksheet you may print, distribute and complete at 2 different points of the lesson. Note: with small modifications (adding or taking away "bits") it can be used for a wide range of year groups Viktoria Tsakyri

This worksheet/ppt presentation contains 5 slides which allow you to use it in different ways according to your group's level and ability. slide 1. project it and ask the students to complete the sentences for each picture while the types of energy are given slide 2. same as slide 1, but the energies aren't given, so it is more appropriate for a higher level group, already familiar with different types of energy slide 3. in case you need your students to concentrate at their own work on their desk print out and distribute this slide slide 4. same as slide 3, but for a higher ability group as the energies aren't given. slide 5. only the energies are included which you can print them out and after the students have started, you can distribute them to the ones who are straggling, showing off your differentiation! Viktoria Tsakyri

This page is split in three parts. 1. questions about refraction through a block and through lenses linked to the diagrams shown 2. questions on "every day" refraction (set fire with a magnifying lens and see through water) 3. questions on the given basic diagram of a refracting telescope. The page is quite "dense" in questions and diagrams, so it is mostly appropriate for higher level groups. But by splitting the tasks in more than one pages and giving more hints and keywords it can be used by any level group. Viktoria Tsakyri

The page is split in 4 tasks. The first two familiarise the students with infrared and ultraviolet radiation. The third assesses their understanding about the discovery of infrared and ultraviolet radiation. The last one, for higher level students, demands a deeper understanding of this topic. Viktoria Tsakyri

This is an activity for understanding the concept of electrical power. It can be used after a theoretical session or while introducing the concept of power. The students should be given a set of 5 bulbs of different values of watt, voltage source, cables, an ammeter, a voltmeter and graph paper. They should be given the formula of calculation the power, P=IxV and instructed how to perform their measurements. The series of questions that follow the measurements are differentiated and can be used to assess the ability and level of understanding. Viktoria Tsakyri

This 8 slide presentation includes: 1. starter linked to a previous lesson about Ohm's law 2. differentiated learning outcomes 3. explanation of series and parallel connection (and a you tube video) 4. instructions for two practicals for each case to investigate the relation of currents and voltages in each case (practical equipment: two resistors, three voltmeters and three ammeters or multi meters, variable dc voltage source) 5. conclusions for each circuit 6. problems to practice for each case 7. review of learning outcomes used as plenary For a lower level group, you may use the starter as a first lesson and the rest as a second one. Viktoria Tsakyri

This 2 page worksheet consists of four parts and can be used for assessing the students during a lesson about Darwin and Lamarck. Suggested way to use it: Part 1. After explaining Lamarck's theory, give your students some time to explain this theory in their own words by following the sequence of the pictures and encourage them to practice their English skills. Part 2. Before talking about Darwin, it is useful to explain the meaning of "natural selection". In this part the students can link it with the giraffes' heights and also practice their Maths skills. Part 3. After mentioning Darwin's observations at Galapagos islands, ask your students to match the birds' beaks with the relevant food. Part 4. This can be your plenary and check if the difference between Darwin and Lamarck is clear and understood. Viktoria Tsakyri

These two coloured pages include applications of infra and ultra sounds which the students need to identify and match to the given pictures. The quick/higher level students are asked for further explanation/comments enhancing their critical thinking. Viktoria Tsakyri

Worksheet with 4 different tasks to assess the understanding of IR and UV radiation. The first 2 tasks can be used as a starter and the last one as a plenary Viktoria Tsakyri

The page includes matching of terms to the correct description. It can be used as a starter or plenary depending on the content of the previous lesson. For SEN students it is suggested to print one "matching set" on A4 size. Viktoria Tsakyri

This is a 20 slide power point presentation containing the formulae of topic 7 on forces and motion. It helps revising, rearranging and applying the formulae on problems.
