This resource includes a highly visual PowerPoint presentation (over 90 slides!) on the topic of ENERGY, forms of energy, energy transformations and energy diagrams. The presentation uses many visual aids and is thoughtfully animated to promote participation from learners of all abilities. Two worksheets and sample exam questions (71 questions with ANSWERS!)) are also included. Appropriate for year 7 or year 8 pupils. Students will learn: 1. that energy is the capacity or ability to do work (the ability to make matter change) 2. that generally, there are 2 types of energy: potential energy and kinetic energy 3. that there are many forms of potential and kinetic energy including: thermal energy (heat), electromagnetic energy (radiated), sound energy, gravitational potential energy (GPE), elastic potential, nuclear, chemical energy and electrical energy. 4. that gravitational energy depends on an object's mass and height above the earth's surface 5. that kinetic energy depends on an object's mass and how fast it is moving 6. that energy is transformed from one form to another 7. that a fuel is stored energy, which must be burnt to release the energy 8. Fuel + Oxygen = Energy + Carbon Dioxide + Water + Waste Product 9. that most of the Earth's energy ultimately comes from the Sun 10. that energy sources can be described as either renewable or Non-renewable 11. that Renewable means can be used again or replaced within a Iifetime 12. some advantages and disadvantages of energy sources 13. the need for energy saving with non-renewable energy sources and ultimately with all energy sources 14. to construct an energy transfer diagram 15. to construct a Sankey diagram 16. that energy is conserved in an energy transformation I hope you find this resource useful. Cheers.

This two-lesson sequence introduces learners to viruses. It includes: • A 31-slide PowerPoint presentation that includes many visual aids and is thoughtfully animated to allow opportunities for discussions during the lesson. • An interactive note-taking worksheet (double-sided A4 size) customized for the presentation. I find that taking notes in this manner keeps lower-level students engaged while allowing differentiation for higher achievers.

This two-lesson sequence introduces learners to Aerobic Respiration. It includes: • A 27-slide PowerPoint presentation that includes many visual aids and is thoughtfully animated to allow opportunities for discussions during the lesson. • A quick practical (hands-on) activity to introduce aerobic respiration. • An interactive note-taking worksheet (double-sided A4 size) that is customized for the presentation. I find that taking notes in this manner keeps lower-level students engaged while allowing differentiation for higher achievers.

*UPDATED January 2017 - More support worksheets added* This resource includes a 56 slide PowerPoint presentation, four activity worksheets, a mind map, a short quiz and a 34-question unit test. Everything is ready to be used or easily edited to suit your learners. • Includes sound clips to bring the learning to life • Animations have been thoughtfully used to promote participation from lower achieving students and discussion from higher ability ones. • 26 learning outcomes listed below By the end of these lessons, pupils will: 1. recognise that sound is made by objects that vibrate 2. define that the frequency of vibration of the source is measured in Hertz (Hz) 3. discuss how sound is made in different musical instruments 4. know that a vibrating source causes the layers of air around it to move 5. discover that sound travels by compressing and expanding the surroundings 6. express that sound travels as a longitudinal wave 7. discover that sound travels best through solids and worst through gases because of the arrangement of the particles 8. explore the relative speed of sound in different mediums 9. explain that sound waves cannot travel through a vacuum because there are no molecules 10. know that sound waves detected by the ear cause the ear drum to vibrate 11. explore the structure of the ear 12. describe how sound is transmitted through the ear to the brain 13. know that different people have different ranges of hearing 14. know that the average human range of hearing is 20 to 20,000 Hz 15. define that loudness is measured in decibels (dB's) 16. discuss that 0 dB is the threshold of hearing and 130 dB's is the threshold of pain whilst 140 dB's causes damage 17. discuss that loud sounds can have permanent and temporary effect on the ear 18. discuss some common causes of ear damage 19. define that noise is unwanted sound 20. discover that a loud sound is produced by a large vibration and vice versa 21. discover that a high pitched sound is produced by a very frequent (quick) vibration and vice versa 22. know that an microphone can change sound to electricity and that this can then be displayed on an oscilloscope 23. know that the wave displayed on an oscilloscope is a transverse wave 24. demonstrate how to identify the amplitude, the wavelength and the frequency of a wave 25. recognise the link between the loudness of the sound and the amplitude of the wave 26. recognise the link between the pitch of the sound and the frequency/wavelength of the wave Cheers!

**This resource has been recommended by the TES Resource Team** Get your learners thinking about electricity and electric circuits. My most popular resource includes: • A lucid and logical 69-slide PowerPoint which includes many visual aids. The slides are thoughtfully animated (not over-animated) to allow opportunities for learners to participate and promote class discussions. • Seven pages of interactive notes (scaffolded notes). These notes fit perfectly with the presentation. I find this activity keeps lower-level students engaged during the lessons while allowing differentiation for higher achievers. • A crossword (with answers), some homework questions and a quiz. **Just print and go! Or customize to fit the needs of your class.** Learning objectives covered in this resources are listed below. • By the end of these lessons, pupils should know: 1. that electricity is a form of energy. 2. that current electricity can be produced from cells, batteries or the mains 3. that there are a range of appliances in the home, which use electricity. 4. that we can represent components by symbols. 5. that current electricity flows in conductors but not in insulators. 6. that a complete path is needed from one side of the battery to the other for electricity to flow. 7. how a switch works. 8. that there are two types of circuit, series and parallel. 9. that current is measured in Amps. 10. that current is measured using an ammeter. 11. how to connect and use an ammeter. 12. that in a series circuit, the current is the same all the way round the circuit. 13. that in a parallel circuit, the current is shared but not lost or used up. 14. that the current in a series circuit depends upon the number and type of components used. 15. that a battery is a store of electrical energy. 16. that voltage is a measure of the amount of energy or push given to the current. 17. that more cells in series equals more voltage. 18. that the effect of voltage upon current and bulb brightness. 19. that an electric current causes a wire to become hot. . 20. that the bigger the current, the higher the temperature of the wire. 21. that if too much current flows, the wire will melt. Hope you find it useful. Your feedback is much appreciated.
