Designing a meal for the King that uses only organic ingredients King Charles III is a passionate environmentalist, who as the former Prince of Wales managed a successful organic farm on his Highgrove estate and has been a big campaigner for environmental issues, including the benefits of organic food, for a number of years. This is one of a series of resources that are designed to allow learners to use the theme of King Charles III’s coronation to develop their knowledge and skills in Design & Technology and Engineering. This resource focusses on designing a meal for the King that is produced using only organic ingredients. The teacher will first explain what is meant by organic ingredients and how they are different to genetically modified (GM) foods. The teacher should explain the design brief and criteria, explaining that the meal must be made from only organic ingredients, serve two people, be either a starter and a main or a main and a dessert, be colourful and use varied textures, and cost less than £5 per person (optional). The learners will then produce a sketch of their idea. This activity can be simplified (particularly for less able students) by providing a partially completed design idea and/or providing a list of organic ingredients that the learners could choose from. Use the handout for learners to sketch their ideas for their organic meal making sure to annotate their design to show how it meets the design criteria. As an extension students could prepare the meal in its entirety; cost the meal per portion for the organic ingredients compared to non-organic ingredients; design a starter or dessert to compliment the meal; or create a menu card to be put on the King’s table. The engineering context Engineers have a moral responsibility to ensure that their designs are sustainable, ethical and do not negatively impact on the environment. In the case of food scientists this involves considering their use of organic and genetically modified ingredients, and when each is or isn’t appropriate. Suggested learning outcomes By the end of this free resource students will be able to understand the difference between organic and GM foods; understand the benefits and limitations of organic foods; and be able to design a meal for King Charles III made entirely from organic ingredients.

Learn about sound waves in this free STEM with this free lesson plan for KS3 From founding communications, such as the fire beacon, to being able to communicate with space, there is no denying that developments in communication have advanced at a rapid speed. This topic presents students with communications of the past, present and future, helping them to understand the principles that form the basis for these developments. This engaging STEM activity is aimed at KS3 students and deals with how animals use sounds and how sounds change in natural phenomena. This is so that a student can understand how sound waves travel. The teacher will first distribute a copy of the ‘Animal Sounds’ handout, which can be downloaded below, to each student. Make sure students understand sound is a longitudinal wave of compressions and rarefactions of the material. Soundwaves follow the laws of wave behaviour, so they are a useful introduction to wave properties. This activity can be simplified (particularly for less able students) by creating a discussion on why different animals have different hearing ranges and their experience of phenomena such as the Doppler effect. Use the handout to discuss different sounds and what they might have learned in other lessons (e.g. music) about pitch, frequency, amplitude etc. As an extension students could produce a display from low to high frequency, showing where the sound ranges used by different animals lie. Students could consider how sounds outside the normal spectrum could be used to develop new products. For example, to make ‘silent’ devices to broadcast sound or data between two points. This is a quick and simple activity that will take approximately 15 minutes. Tools/resources required Calculators The engineering context Sounds are vibrations travelling through materials. Many animals make sounds, either for communication or for location. Sound travels at different speeds in different materials. Generally, the denser the material, the faster the sound will travel. Sound is a longitudinal wave of compressions and rarefactions of the material (a rarefaction involves particles in the material being more spread out than usual). Sound waves follow the laws of wave behaviour, so they are a useful introduction to wave properties. Suggested learning outcomes By the end of this free resource students will know that sound is produced by objects vibrating and they will understand that sound is a longitudinal wave. They will also know about the range of frequencies that can be heard by humans and other animals and they will understand that sound travels at different speeds in different mediums.
