Study Notes
Components of Food
- Major nutrients in food are carbohydrates, proteins, fats, vitamins, minerals, dietary fibers, and water.
- Carbohydrates and fats provide energy to the body.
- Proteins are essential for growth and maintenance.
- Vitamin A is required for good eyesight.
- Calcium is required for healthy bones.
- Foods rich in fats include groundnuts and ghee.
- Foods rich in starch include rice and potatoes.
- Foods rich in dietary fiber include whole grains and fresh fruits.
- Foods rich in protein include grams and fish.
- A balanced diet includes all essential nutrients in proper quantities, roughage, and water.
- Deficiency diseases occur due to the lack of specific nutrients over a long period.
Fortified Food
- Fortification of food involves adding essential vitamins and minerals to staple foods (like rice, wheat, oil, milk, and salt).
- Fortified foods improve nutritional content.
- Fortified foods have a specific logo as per FSSAI standards.
Obesity
- Obesity is a condition caused by excessive fat accumulation in the body.
- A person is considered obese if their body weight is at least 20% higher than the recommended weight.
Deficiency Diseases
- Specific vitamins and minerals have specific roles in the body.
- A deficiency in a vitamin or a mineral can lead to specific deficiency diseases/disorders.
- Examples of deficiency diseases/disorders are provided in a table format.
Sorting Materials into Groups
- Materials can be sorted on the basis of shape, color, uses, or material of manufacture.
- Wood is a material that can be used to make tables, chairs, beds, doors, and boxes
Separation of Substances
- Separating components of a mixture is crucial for removing harmful or unwanted components.
- Various methods for separating materials include handpicking, threshing, winnowing, sieving, sedimentation, decantation, filtration, and evaporation.
Getting to Know Plants
- Roots absorb water and minerals from the soil.
- Stems hold the plant upright and conduct water to the leaves.
- Stems also provide structural support for the plant.
- The number of petals and sepals in a flower may differ among species.
- Plants with fibrous roots generally have parallel venation patterns in their leaves. Similarly, plants with reticulate venation have taproots.
- Climbers are plants with a weak stem that supports itself by climbing and attaching to other surfaces.
Living Organisms and their Habitats
- A habitat is the area where an organism lives.
- Adaptations are the specific features or habits that help organisms survive in their habitat.
- Some examples of adaptations in camels include long legs for desert survival, excretion of concentrated urine, and ability not to sweat.
- Examples of adaptations in fish are sleek shape and scales for swimming, and gills for oxygen absorption.
- Different habitats exist. For instance, forests, grasslands, deserts, and mountains are terrestrial habitats; lakes, rivers, and oceans are aquatic habitats.
- Plants and animals have physical adaptations and behaviors suited for living in their respective habitats.
Motion and Measurement of Distance
- Motion refers to the movement of an object over time.
- Periodic motion describes movement that repeats in a certain amount of time.
- Non-periodic motion does not repeat at a fixed interval.
Light, Shadows, and Reflections
- Light sources emit light energy.
- Materials can be categorized based on their ability to transmit light. Opaque materials block light and cast clear shadows, transparent materials allow light to pass through and cast no shadows, and translucent materials allow some light to pass through and cast unclear shadows.
- The shape of a shadow depends on the shape of the object and the direction of the light source. The size and shape of the shadow change as these factors change.
Electricity and Circuits
- Electric circuits are arrangements that conduct electricity.
- Components like switches, batteries, bulbs, wires are crucial for circuit operation.
- A switch opens or closes a circuit, controlling the flow of electricity.
- Conductors allow the flow of electricity, while insulators prevent it.
- Circuits are arranged in various ways.
- Rubber and plastic are examples of electrical insulators.
- Electricity flows through conductors (metals).
