Home Science Practicals (Detailed Steps)

1. Meal Planning and Nutrition Analysis

Objective: Plan a balanced diet for a specific age group and analyze its nutritional value.

Materials Required:

Food chart (containing calorie, protein, vitamin, and mineral values).

Notebook and pen.

RDA (Recommended Dietary Allowance) chart.

Procedure:

1. Select an age group (children, teenagers, adults, elderly, pregnant women, etc.).

2. List the essential nutrients required for that group.

3. Plan a balanced diet including breakfast, lunch, and dinner.

4. Use a food chart to calculate the total calories and nutrients.

5. Compare with the RDA values and analyze deficiencies or excesses.

Observations:

Note if the meal meets the daily nutritional needs.

Identify missing nutrients and suggest alternatives.

Conclusion:

Explain whether the diet is balanced or needs modifications.

2. Fabric and Clothing Care

Objective: Identify different fabrics and demonstrate proper cleaning and stain removal techniques.

Materials Required:

Samples of cotton, silk, wool, and synthetic fabrics.

Common stains (oil, ink, coffee, etc.).

Cleaning agents (detergents, vinegar, lemon juice, baking soda).

Iron and washing equipment.

Procedure:

1. Identify the type of fabric using texture, strength, and absorption tests.

2. Apply different stain removal methods based on fabric type:

Oil stains: Use dish soap and warm water.

Ink stains: Use alcohol or vinegar.

Coffee stains: Use baking soda paste.

3. Wash the fabric samples using suitable methods (hand wash, machine wash).

4. Dry and iron the fabric to observe changes.

Observations:

Note which stain removal methods were most effective.

Observe how different fabrics react to heat and washing.

Conclusion:

Suggest best practices for washing and maintaining different fabrics.

3. Interior Decoration and Space Management

Objective: Design an interior layout using color schemes, furniture arrangement, and space management.

Materials Required:

Graph paper or drawing software.

Color pencils or digital tools for color schemes.

References for furniture design.

Procedure:

1. Choose a specific room (study room, kitchen, bedroom, etc.).

2. Sketch a floor plan with proper dimensions.

3. Select an appropriate color scheme for walls and furniture.

4. Arrange furniture and appliances to maximize space and usability.

5. Present the final layout with explanations.

Observations:

Evaluate how space is utilized efficiently.

Identify if the color scheme enhances the room’s purpose.

Conclusion:

Suggest improvements for better space management.

Computer Science Practicals (Detailed Steps)

1. Programming in Python

Objective: Write a program to find the largest of three numbers.

Software Required: Python (IDLE, VS Code, or Jupyter Notebook).

Code:

# Program to find the largest of three numbers

a = int(input("Enter first number: "))

b = int(input("Enter second number: "))

c = int(input("Enter third number: "))

if a > b and a > c:

    print("Largest number is:", a)

elif b > c:

    print("Largest number is:", b)

else:

    print("Largest number is:", c)

Procedure:

1. Open a Python editor and write the code.

2. Save and run the program.

3. Input different sets of numbers and observe results.

Observations:

Check whether the correct largest number is displayed.

Modify the code to include exception handling for errors.

Conclusion:

Understand how conditional statements work in Python.

2. Database Management using SQL

Objective: Create a student database and retrieve records using SQL queries.

Software Required: MySQL, SQLite, or any database software.

SQL Commands:

-- Creating the database

CREATE DATABASE StudentDB;

USE StudentDB;

-- Creating the table

CREATE TABLE Students (

    ID INT PRIMARY KEY,

    Name VARCHAR(50),

    Age INT,

    Marks INT

);

-- Inserting records

INSERT INTO Students VALUES (1, 'Rahul', 16, 85);

INSERT INTO Students VALUES (2, 'Anjali', 17, 92);

INSERT INTO Students VALUES (3, 'Rohit', 16, 78);

-- Retrieving students scoring above 80

SELECT * FROM Students WHERE Marks > 80;

Procedure:

1. Open MySQL or SQLite and create a new database.

2. Write and execute the commands to create the student table.

3. Insert sample data and retrieve records using queries.

Observations:

Verify if the correct records are retrieved.

Modify queries to filter data based on different conditions.

Conclusion:

Learn database management and query execution.

3. Website Design using HTML & CSS

Objective: Create a basic webpage with a navigation bar and images.

Software Required: Notepad++, VS Code, or any text editor.

Code:

<!DOCTYPE html>

<html>

<head>

    <title>My Web Page</title>

    <style>

        body { font-family: Arial, sans-serif; text-align: center; }

        nav { background-color: #333; padding: 10px; }

        nav a { color: white; margin: 10px; text-decoration: none; }

    </style>

</head>

<body>

    <nav>

        <a href="#home">Home</a>

        <a href="#about">About</a>

        <a href="#contact">Contact</a>

    </nav>

    <h1>Welcome to My Web Page</h1>

    <p>This is a simple webpage using HTML and CSS.</p>

    <img src="image.jpg" alt="Sample Image" width="300px">

</body>

</html>

Procedure:

1. Open a text editor and create a new file with a .html extension.

2. Copy and paste the HTML code.

3. Save and open the file in a web browser.

4. Modify styles and add more content as needed.

Observations:

Check if the navigation bar and styling are working correctly.

Experiment with different font styles and colors.

Conclusion:

Understand the basics of web design and CSS styling.
