What did you eat at home today? Find out what your friend ate today. Did you eat the same kind of food yesterday and today? We all eat different kinds of food at different times, isn’t it? 1.1 FOOD VARIETY Activity 1 Ask your friends in the school about the items they would be eating during a day. See if you can also get this information from friends staying in different states of India. List all the items in your notebook as given in Table 1.1, for as many friends as possible. Table 1.1 What do we eat? Name of the Food items student/friend eaten in a day There seems to be so much variety in the food that we eat. What are these food items made of? Think about rice cooked at home. We take raw rice and boil it in water. Just two materials or ingredients are needed to prepare a dish of boiled rice. On the other hand, some food items are made with many ingredients. To prepare vegetable curry, we need different kinds of vegetables, salt, spices, oil and so on. Activity 2 Choose some of the items you listed in Table 1.1 and try to find out what ingredients are used to prepare these, by discussing with your friends and elders at home. List them in Table 1.2. Some examples are given here. Add some more items to this list. Table 1.2 Food items and their ingredients Food Item Ingredients Roti/chapati Atta, water Dal Pulses, water, salt, oil/ ghee, spices What do we find? Do we find some ingredients common for different food items? Discuss in class. So, where do these ingredients come from? 1.2 FOOD MATERIALS AND SOURCES It may be easy for us to guess the sources of some of the ingredients that we listed in Table 1.2. Fruits and vegetables, for instance. Where do they come from? Plants, of course! What are the sources of rice or wheat? You may have seen paddy or wheat fields with rows and rows of plants, which give us these grains. And then, there are food items like milk, eggs, meat, chicken, fish, prawns, beef, pork and such others, which come from animals. Activity 3 Let us take the food items listed earlier and try to find out where they come from — the ingredients and their sources. prepare food items andSome examples are shown in Table 1.3. their sourcesFill in the blanks in Table 1.3 and add Food Item Ingredients Sources Idli Rice Plant Urad dal Salt Water Chicken curry Chicken Animal Spices Oil/ghee Plants/ Animals Water Kheer Milk Animal Rice Plant Sugar What do we conclude from Activity 3? Plants are the sources of food ingredients like grains, cereals, vegetables and fruits. Animals provide us with milk, meat products and eggs. Cows, goats and buffaloes are some common animals which give us milk. Milk and milk products like butter, cream, cheese and curd are used all over the world. Can you name some other animals which give us milk? 1.3 PLANT PARTS AND ANIMAL PRODUCTS AS FOOD Plants are one source of our food. Which parts of a plant are these? We eat many leafy vegetables. We eat fruits of some plants. Sometimes roots, sometimes stems and even flowers. Have FOOD: WHERE DOES IT COME FROM? Food item with plant as the major source Ingredients/source Plant part which gives us the ingredient 1. Brinjal curry Brinjal Fruit Chilli as spice (any other) Fruit Oil from groundnut, mustard, soybean, any other plant Seed 2. 3. Floweryou ever eaten pumpkin flowers dipped in rice paste and fried? Try it! Some plants have two or more edible (eatable) parts. Seeds of mustard plants give us oil and the leaves are used as a vegetable. Can you think of the different parts of a banana plant that are used as food? Think of more examples where many parts of a single plant are used as food. Activity 4 From all the food items you have listed in Table 1.3, choose those items whose ingredients are obtained from plants. Which part of a plant? Identify these and list the food items and plant parts as shown in Table 1.4. Activity 5 Take some dry seeds of moong or chana. Put a small quantity of seeds in a container filled with water and leave this aside for a day. Next day, drain the water completely and leave the seeds in the vessel. Wrap them with a piece of wet cloth and set aside. The following day, do you observe any changes in the seed? A small white structure may have grown out of the seeds. If so, the seeds have sprouted. If not, wash the seeds in water, drain the water and leave them aside for another day, covered with a wet cloth. The next day, see if the seeds have sprouted. After washing these sprouted seeds, you can eat them. They can also be boiled. Add some spices and get a tasty snack to eat. Do you know where honey comes from, or how it is produced? Have you seen a beehive where so many bees keep buzzing about? Bees collect nectar (sweet juices) from flowers, convert it into honey and store it in their hive. Flowers and their nectar may be available only for a part of the year. So, bees store this nectar for their use all through the year. When we find such a beehive, we collect the food stored by the bees as honey. 1.5 WHAT DO ANIMALS EAT? Do you have cattle or a pet that you take care of? A dog, cat, buffalo or a goat? You will then surely be aware of the food, the animal eats. What about other animals? Have you ever observed what a squirrel, pigeon, lizard or a small insect may be eating as their food? Activity 6 Several animals are listed in Table 1.5. For some of them, the type of food they eat is also given. Fill in the blanks in the table. Activity 7 Have a look again at Table 1.5 and group the animals entered here as follows. Place animals which eat only plants or plant products in Group 1. These are called herbivores. There are some animals which eat other animals. Place these in Group 2. These animals are called carnivores. Do you find some animals which eat both plants and animals? Place them in Group 3. These are called omnivores. Prepare a table as in Table 1.6 and enter these separately in the three columns, as shown.
