Students’ Learning Outcomes

· Identify the sources of common food.

· Classify different types of foods into their basic groups.

· Explain the properties of major food groups.

Information for Teachers

· We get different food items (fruits, vegetables, meat etc.) from two basic sources i.e. animals and plants.

· The major food groups are carbohydrates, proteins, fats, vitamins, minerals and water.

· Carbohydrates provide us energy. We get carbohydrates from bread, cereals, vegetables and legumes.

· Proteins from meat, milk, eggs, yogurt, cheese, grains and legumes.

· Vitamins are required in small amount but are essential for many biochemical reactions in our bodies. Vitamins can be divided into A, B, C, D, E and K. they are present in colors fruits, vegetables, fats, oils, meat and milk.

· Minerals are present in fruits and vegetables. They help in making bones and teeth strong. Important minerals are calcium, iodine, iron, magnesium, potassium, sodium and zinc.

· Fats provide us energy and are also required for brain development and vision. We get fats from meat, milk, butter, cheese, cooking oil and dry fruits.

· Water is extremely important for life because it is an essential constituent of protoplasm.

Worm up Activity

· Let students recall the previous knowledge about the functions of food for our bodies i.e. energy and growth.

· Ask students to recall previous knowledge of different food groups.

· Ask students to make a list of food items they eat daily. Enlist these food items on board then introduce today’s lesson.

Development

Activity 1

· Divide the class into different groups. They eat daily and also enlist the sources from where they get it.

· Ask students enlist foods into as many types, groups and sources as they can.

· Now ask the groups to read out their lists.

· Ask the students from where do we get our food?

· Guide the students in concluding that the main sources of food for us are animals and plants.

Activity 2

· Ask the students (by using the same list that they prepared before) to arrange food items into as many groups as possible on the basis of similarities, e. g. they can put bread and roti in the same group whereas apples, bananas, and oranges in the same group.

· Ask the groups to read out the list of at least one of the food groups they made.

· Now introduce different food groups i.e. carbohydrates, Proteins, fats, vitamins, minerals and water to students.

· Describe in detail the major roles played by different food groups in our daily life.

Food group	Food item	Functions
Carbohydrates	Potato, rice, grains, bread, chapatti	Provide energy
Proteins	Meat, milk, yogurt, cheese, red beans, eggs	Help in building body muscles, growth and repair of body
Fats	Oil, ghee, cream, milk	Help to maintain body temperature, besides main source of energy (required in small quantities)
Minerals	Salt, spinach, yogurt, milk, green leafy vegetables	Help to build strong bones and teeth
Vitamins	Fruits, vegetables	Protects from diseases, eyesight, for good digestion, healing wounds and skin problems
Water	Drinking water, fruits, vegetables, soft drinks	Transport materials in our body and maintain body temperature
