Source: NCERT Class VI Science, Chapter 1, Pages 1โ7 Class: VI
Food Variety ๐ฟ
๐ Ingredients = the materials used to prepare a food item.
- Food eaten varies across different regions of India.
- Some food needs very few ingredients โ boiled rice needs only raw rice and water.
- Some food needs many ingredients โ vegetable curry needs vegetables, salt, spices, and oil.
๐ Examples of Food Items and Their Ingredients
| Food Item | Ingredients |
|---|---|
| Roti / Chapati | Atta, water |
| Dal | Pulses, water, salt, oil/ghee, spices |
Food Materials and Sources ๐ฟ
๐ All food comes from two main sources: Plants and Animals.
- Plants give us grains, cereals, vegetables, and fruits.
- Animals give us milk, meat products, and eggs.
๐ Ingredients and Their Sources
| Food Item | Ingredient | Source |
|---|---|---|
| Idli | Rice | Plant |
| Chicken curry | Chicken | Animal |
| Chicken curry | Oil / ghee | Plants / Animals |
| Kheer | Milk | Animal |
| Kheer | Rice | Plant |
Plant Parts as Food ๐ฟ
๐ Edible = eatable parts of plants or animals.
Plants give us food from different parts โ leaves, fruits, roots, stems, and even flowers.
โ ๏ธ Some plants have two or more edible parts โ the mustard plant gives oil from its seeds AND a vegetable from its leaves.
๐ Plant Parts and Food Examples
| Food Item | Ingredient | Plant Part That Gives the Ingredient |
|---|---|---|
| Brinjal curry | Brinjal | Fruit |
| Brinjal curry | Chilli as spice | Fruit |
| Oil | Oil from groundnut, mustard, or soybean | Seed |
Animal Products as Food ๐ฟ
๐ Animal Products
| Product | Source |
|---|---|
| Milk | Cows, goats, buffaloes |
| Butter, cream, cheese, curd | Made from milk |
| Meat | Animals |
| Eggs | Animals |
๐ Milk and milk products like butter, cream, cheese, and curd are used all over the world.
Sprouted Seeds and Honey ๐ฟ
Sprouted Seeds
๐ Sprouted seeds = seeds that show a small white growth after soaking โ they have sprouted.
โ๏ธ How to Sprout Seeds (Moong or Chana):
Soak dry seeds in water for one day โ Drain the water completely โ Wrap seeds in a wet cloth and set aside โ Small white structures grow out โ the seeds have sprouted โ ๏ธ
- Sprouted seeds can be washed and eaten raw, or boiled and eaten with spices.
โ ๏ธ Do NOT taste unknown plants โ some plants could be poisonous.
Honey
๐ Nectar = sweet juices collected by bees from flowers.
โ๏ธ How Honey Is Made:
Bees collect nectar from flowers โ Bees convert nectar into honey โ Honey is stored in the beehive โ Humans collect honey from the beehive โ ๏ธ
- Flowers and nectar are available only for part of the year, so bees store honey for use throughout the year.
What Do Animals Eat? ๐ฟ
๐ Animals are grouped into three types based on what they eat.
๐ Classification of Animals by Food ๐
| Type | Definition | Source Example |
|---|---|---|
| Herbivore | Eats only plants or plant products | Cow |
| Carnivore | Eats only other animals | Lion |
| Omnivore | Eats both plants and animals | Dog |
๐ Animals and Their Food
| Animal | Food Eaten |
|---|---|
| Buffalo | Grass, oilcake, hay, grains |
| Cat | Small animals, birds, milk |
Common Confusions โ ๏ธ
| Confusion | Clarification |
|---|---|
| Herbivore eats only herbs | Herbivore eats any plant or plant product โ not just herbs |
| Honey is a plant product | Honey is made by bees (animals) from nectar โ it is an animal product |
| All plant parts are safe to eat | Only specific parts of specific plants are edible โ some plants are poisonous |
| Carnivore and omnivore are the same | Carnivore eats ONLY animals; omnivore eats BOTH plants and animals |
Memory Aids ๐ก
| What to Remember | Mnemonic / Trick |
|---|---|
| Three types of animal eaters | ๐ก "H-C-O: Herbivores eat Hay, Carnivores eat Chicken, Omnivores eat One of everything!" |
| Two main sources of food | ๐ก "Think PA โ Plants and Animals โ our two food parents!" |
| How honey is made | ๐ก "Bees are kitchen chefs โ they collect flower juice (nectar) and cook it into honey in their hive!" |
| Sprouting steps | ๐ก "Remember S-D-W: Soak the seeds, Drain the water, Wrap in wet cloth โ then watch the tiny white tail grow!" |
