Lesson 6: Children should learn that humans have teeth - molars for chewing, canines for tearing, incisors for cutting - and that teeth help us to eat and that the shape of the teeth makes them useful for different purposes.
Children should learn to identify criteria for their design, to select tools and materials and use correct vocabulary to name and describe them, to assemble, join and combine materials to make a winding mechanism and to understand the need for a stable structure to support a mechanism. This is lesson 3 in a unit of work.
Children should learn to use existing fabric designs as inspiration for their own pattern-making, to develop and communicate their design ideas through drawing and modelling and to make and/or use a simple paper pattern/template. This is lesson 3 in a unit of work.

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

An overview of the homeostatic principles involved in fluid balance in the human body. The kidneys are explored along with the chemicals that influence the functioning of the renal system. This presentation could be amended pending angle that lesson is aimed towards.
A great resource to support children in understanding the different stages of the human life cycle. Included in this resource pack is:
An information PowerPoint exploring the differences of each stage of the human life cycle.
A life cycle worksheet for children to complete (differentiated)
A worksheet where children can note down the different things humans can do in each stage.
