2 CURRICULUM CONTEXT SOCIAL, PERSONAL AND HEALTH EDUCATION Strand: Myself Strand Unit: Taking care of my body The child should be enabled to Health and well-being realise that each individual has some responsibility for his/her health and that this responsibility increases as he/she gets older. Food and nutrition explore some factors that influence the consumption of different food products. discuss and examine the importance of proper food hygiene. GEOGRAPHY Strand: Human environments Strand Unit: People living and working in the local area and people living and working in a contrasting part of Ireland People at work explore and investigate, especially through practical studies, a small number of the common economic activities of people in the locality and in a contrasting part of Ireland. Strand: Natural environments Strand Unit: The local natural environment investigate and become familiar with some natural features in the local environment. SCIENCE Strand: Environmental awareness and care Strand unit: Environmental awareness recognise how the actions of people may impact upon environments.

3 Taste Buds Notes SCREEN 1 Often the foods we eat are nothing like their original form. A lot of work goes in to producing some foods. The slide shows a number of raw ingredients or animal sources and the processes that they undergo to become a food product. The food product is hidden until you click on the Reveal button at the bottom of the screen. Ask the children to suggest answers for each example. Encourage them to think of more examples. They could include: Beef Products - Lots of other beef products come from cattle too such as fillet steak, sirloin steak, stewing steak, rib of beef etc. Wheat - Lots of other foods are also made with wheat, for example, scones, croissants, cakes, pasta. Dairy - A lot of other products that can be made from milk, such as cheese, yoghurt, icecream, buttermilk. The process for making each of these products is different. The next slide will show a short video of how cheese is made. Chicken - A lot of other products come from chicken, including chicken wings, chicken legs and some processed chicken products such as chicken nuggets and chicken burgers. It is best to choose the unprocessed varieties of chicken. Orange - Oranges are also used for fruit salads, to make marmalade and for adding flavour to foods. SCREEN 2 There is a specific process involved in making cheese from milk. Different processes are used to make different types of cheese. The screen shows a short video on the production of cheese from milk. Ask the class if they have any ideas how cheese is made before showing the video. Watch it with the class and then discuss it. The video plays automatically. The teacher can use the video controls to pause/play it.

This screen shows milk containers on one side and a number of foods made from milk on the other. Explain, using the example of milk on the screen, that the same raw materials can be processed in different ways to produce different foods. Butter Making Process Butter is made by churning cream or milk. Churning produces small butter grains floating in the cream. This watery liquid is called buttermilk. The buttermilk is drained off. Then the grains are worked - pressed and kneaded together until butter is formed. Cheese Making Process Cheese is another product made from milk. Bacteria are added to whole milk and it forms hard curds and watery whey. The whey is drained off and the curd is compressed, processed and stored to form cheese. Cheese has historically been an important way of storing milk over the years. It is a food product that dates back to prehistory in Middle Eastern and European cultures. A considerable amount of cheese is made commercially from other milks, especially goat and sheep. Yogurt Making Process Yoghurt making is a process similar to cheese making, only the process is stopped before the curd becomes very hard. Cream Cream is the fat skimmed off the top of milk or separated by machines. SCREEN 4 Food preservation is the process of treating a food so that it keeps for longer and slows down food going off or rotting. This screen lists some of the reasons for preserving food. Ask the class if they can think of any foods that have been preserved in some way. There are lots of examples on the slides to follow.

5 Taste Buds Notes SCREEN 5 The process of smoking can be used to preserve fish. This screen shows a short video on the fish smoking process. Ask the class if they have any ideas how fish is smoked before showing the video. Watch it with the class and then discuss what they have seen and learned. The video plays automatically. The teacher can use the controls to pause/play it. SCREEN 6 There are lots of different methods of food preservation i.e. brining, freezing, smoking, canning, drying. Some foods can be preserved in a variety of ways, for example fish can be smoked, canned, brined or frozen. See Additional Teacher Information at the end of this session for more details on preservation methods. This screen displays some foods and some food preservation methods that can be used on different foods. Click Reveal Example to display the preserved foods. Go through the on-screen examples with the children. Ask them to suggest other examples.

6 Taste Buds Notes SCREEN 7 Fruits, vegetables and potatoes are often processed before they are sold to restaurants, hotels and shops which sell or serve food. The screen shows a short video on vegetables and potato production for the catering sector. Play the video and discuss it with the class. Talk about how vegetables are prepared in the home in comparison to how they are prepared in the video. The video plays automatically. The teacher can use the controls to pause/play it.

8 Taste Buds Extension Activities activity 1 foods that are made from... Ingredients can be used in different ways to make different foods. The screen shows a number of food items across the top. The children must suggest what other foods could be made using these ingredients, such as butter from milk or bread from wheat. Invite the children to make suggestions themselves about what food products can be made with the raw ingredients. The children s answers can be typed on to the screen. activity 2 foods and processes Clicking the Print button, print out three separate circle images. These images can be cut out and stacked together. Food sources (plant and animal) can then be matched up with ingredients and food products. The children can then turn the wheels to match the foods to the process. They can then colour in the final chart. They can work in small groups or on their own. HOMEWORK ACTIVITY SUGGESTIONS 1: Ask the children to look at the food at home again with their parent/guardian and write down the different ingredients that go into different foods. 2: Ask the children to look at where different foods are stored in the home and find out why they need to be stored in certain places, e.g. cupboard, fridge, freezer.

10 Taste Buds Additional Teacher Information PRESERVATION METHODS Drying Drying is one of the oldest methods of food preservation. Many fruits can be dried; for example apples, pears, bananas, mangoes, papaya, and coconut. Currants, sultanas and raisins are all forms of dried grapes. Drying is also the means of preservation for cereal grains such as wheat, maize, oats, barley, rice, millet and rye. Smoking Meat, fish and some other foods can also be preserved through the use of smoke. The combination of heat to dry the food without cooking it, and smoke preserves the food. INGREDIENTS AND THE FOODS MADE FROM THEM Here are some examples. Eggs: Scrambled eggs, poached eggs, boiled eggs, fried eggs, pastry, pavlova, quiche, omelette. Beef: Beef stew, shepherds pie, beef curry, beef goulash, beef burgers, roast beef, spaghetti bolognese, lasagne. Milk: Cheese, cream, custard, creamed rice, porridge, hot chocolate, milky drinks. Wheat: Bread, crackers, biscuits, scones, croissants. Freezing Freezing is one of the most commonly used processes commercially and domestically for preserving a very wide range of foodstuffs. Canning Canning involves cooking foods like fruits or vegetables, meat or fish, sealing them in sterile cans or jars, and boiling the containers to kill or weaken any remaining bacteria. Food preserved by canning or bottling is at risk of spoilage once the can or bottle has been opened. Lots of care is needed during the canning process so that water or micro-organisms do not get into the can. If this happens, gas production in the can will cause it to swell or burst. This is why you should never purchase a damaged can in the supermarket.
