Unit(1)- • Food and Nutrition• What happens if you do not eat food for an

entire day? You start feeling tired and weak by the end of the day. Your body needs food to nourish and energies itself.

• Food is essential for living beings as it-1. Provides the energy necessary to carry out

various life activities.2. Helps in the growth and repair or

replacement of worn-out cells.3. Protects the body from various diseases and

keeps it fit.

Type of food

• Some food items can be eaten raw, Whereas others are cooked before eating. Most fruits and certain vegetables are eaten raw.

• One the other hand, rice, pulses, vegetables, meat, fish and eggs are cooked to make a variety of dishes.

Source of food

• Raw food • Cooked food

Food from plants

Foods from Animals

FOOD CHAIN

GRASS GRASSHOPPER

LIZARDEAGLEFOX

Fiber to Fabric

• Brief History of clothing• Like food and shelter, clothing is a basic

human requirement. Some evidence suggests that humans started wearing clothes nearly 100,000-500,000 years ago. The earliest clothes were made of animal skins, furs, leaves, grasses, barks of tress, or even bones and shells.

Types of Fabrics

Cotton Silk Wool

MATTER

• Matter is anything that has mass and occupies space.

Composition of Matter

A. Atom- An atom is the smallest indivisible particle of matter.

B. Element- An element is a substance made of same type of atoms.

C. Compound- A compound is a substance made of different types of elements.

Properties of Materials

I. AppearanceII. Hardness III. Texture IV. Transparency

PHYSICAL STATE

i. Solid state ii. Liquid state iii. Gaseous state

THE LIVING AND THE NON-LIVING

• Things around us-

Characteristics of living things

I. GrowthII. MovementIII. Food and NutritionIV. Respiration

MEASUREMENT

• What is Measurement?• Measurement allows us to know the exact

value of a physical quantity.

MOTION

• An object that change it position with time, relative to its surrounding, is said to be in motion.

Types of Motion

1. Translational Motion 2. Circular Motion 3. Rotational Motion4. Oscillatory and vibratory Motion5. Periodic and Non-Periodic Motion

• What is light?• In a dark room, the electric

bulb produces light that enables us to see things. So, we are able to see things because of light. We see an object only when the light from reaches our eyes.

Light

• Source of light1. Sun2. Bulb3. Candle4. fire

Electricity

• What is electricity?• The working of a torch shows that something

must be flowing through the bulb when the torch is switched on. This things that casus the bulb to glow is called electricity.

Electric circuit

Magnet

•

Magnetic and non-magnetic materials

• The materials get attracted to a magnet are called magnetic materials.

• The material that are not affected in any way by a magnet are called non-magnetic material.
