Here is a series of lessons I did for food testing. I have broken them down to a food test per lesson, building scenarios in that will help students visualise the real world use of these skills. Thanks to other TES members with regards to writing frames. I hope you find these useful.
**UPDATED May 2016** Thank you for all the positive comments and ratings.
This resource includes a 53 slide PowerPoint presentation, three activity worksheets, a mind map, and a quiz . I used them to teach the unit on sound with my Year 7 and Year 8 classes. Appropriate in KS3 or KS4.
By the end of these lessons, pupils will know:
1. that sound is made by objects that vibrate
2. that the frequency of vibration of the source is measured in Hertz (Hz)
3. how sound is made in different musical instruments
4. that a vibrating source causes the layers of air around it to move
5. that sound travels by compressing and expanding the surroundings
6. that sound travels as a longitudinal wave
7. that sound travels best through solids and worst through gases because of the arrangement of the particles
8. the relative speed of sound in different mediums
9. that sound waves cannot travel through a vacuum because there are no molecules
10. that sound waves detected by the ear cause the ear drum to vibrate
11. the structure of the ear
12. how sound is transmitted through the ear to the brain
13. that different people have different ranges of hearing
14. that the average human range of hearing is 20 to 20,000 Hz
15. that loudness is measured in decibels (dB's)
16. that 0 dB is the threshold of hearing and 130 dB's is the threshold of pain whilst 140 dB's causes damage
17. that loud sounds can have permanent and temporary effect on the ear
18. that some common causes of ear damage
19. that noise is unwanted sound
20. that a loud sound is produced by a large vibration and vice versa
21. that a high pitched sound is produced by a very frequent (quick) vibration and vice versa
22. that an microphone can change sound to electricity and that this can then be displayed on an oscilloscope
23. that the wave displayed on an oscilloscope is a transverse wave
24. 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

This pack contains a massive bank of questions that I have created by carefully going through the detailed specification content for the core Edexcel biology exam. Listed under the title 'spec. questions' these are all questions that are likely to come up and have in the past. By creating these questions I have also made educated guesses about the 6, 4, and 3 markers. If you have an answer prepared for every single question from the 'spec. questions' you are guaranteed 90% + on your B1 Edexcel exam.
Also included in this pack are revision quizzes and worksheets and answers (issued by the Edexcel exam board.)
This pack contains a massive bank of questions that I have created by carefully going through the detailed specification content for the Further Edexcel Biology exam. The bank of questions contains EVERYTHING that the exam could possibly contain. Listed under the title ' Topic x - Spec. Questions' are all questions that are likely to come up; many of the questions have already come up in previous B3 exams, proving that these questions are highly likely to come up in the exam. Please note Edexcel are likely to repeat questions from previous years so answer ALL questions in the 'spec. Q's' bundles even if you have seen them in past papers. By creating these questions I have also made educated guesses about the 6, 4, and 3 markers. If you have an answer prepared for every single question from the 'spec. questions' you are guaranteed 90%+ on your B3 Edexcel exam. I can not stress how important and essential the spec. questions are, make sure they are completed in as much detailed as possible and if you answer all the questions using textbooks these can make up the core of very focused revision notes. This is the perfect resource for students and teachers, students can use the Specification Questions over the whole course and build up their own notes or it could be used when cramming just before the exam. Teachers can even use this pack to structure their lessons and make sure their students can answer all the specification questions or set relevant questions from the pack as homework questions as well as an end of unit test (because the Specification questions ar arranged in Topic.)
Also included in this pack are quizzes, flash cards worksheets and answers (issued by the Edexcel exam board.)
