Food Cooked and Raw Food for Class 1 Science

We already know about the food we get from plants and animals. Over the years, humans have developed several methods to enhance the taste and variety of items we eat.
Raw food cannot be consumed directly; it is cooked and made suitable for consumption. Cooking involves various methods and ingredients which varies across the globe.
It is not possible to eat all kinds of food without cooking. Moreover, humans are not capable of digesting many things without being cooked.
This concept will help the learners to differentiate between raw and cooked items.

After reading the concept, students will be able to:

  • Give examples of different food items based on cooking methods used.
  • Define different methods of cooking food.
  • Identify different cooking utensils.

Each concept is explained to class 1 students using descriptions, illustrations, and concept maps. After you go through a concept, assess your learning by solving the two printable worksheets given at the end of the page.

Some food items can be consumed without cooking and are called raw food. Do you cook your salad before you eat it? What about a fish?

Raw fruits and vegetables:

However, all vegetables cannot be eaten raw; only some, like carrots, onions, etc., can be consumed directly.
