Saba and Aparna reunite, noticing how they and the world around them have changed! This chapter follows their story, exploring the rhythms of day, night, and seasons in nature. Let’s join them to discover how these changes shape our lives!
Changes around Us in a Day: Day and Night
Saba and Aparna see changes everywhere. Let’s explore how day turns to night!
Observing Daily Changes
- Saba and Aparna notice changes like growing taller and new trees at school.
- The world changes daily as day becomes night and night turns to day.
- The Sun seems to rise in the east and set in the west each day.
- Things like leaves falling and flowers blooming show nature’s constant change.
- Fun example: Day and night are like a dance between the Sun and Earth!
Demonstration: Day and Night
A fun activity shows why day and night happen. Let’s try it!
Understanding Earth’s Rotation
- Step 1: Place a globe on a table and flash a torch on one side of the globe; the torchlight represents the Sun, with the lit side as day and the dark side as night.
- Step 2: Rotation—Slowly rotate the globe while keeping the torch steady.
- Step 3: Observe how different parts of the globe face the light as it rotates.
- The Earth rotates, not the Sun, causing day and night as observed with the torch.
- Fun example: The globe and torch are like a game showing day and night!
Changes around Us in a Year: Seasons
Saba and Aparna explore how nature changes over a year. Let’s see what they find!
Observing Seasons
- Saba and Aparna sit in the school garden, looking at their seasons’ journal.
- Nature changes slowly, with weather getting hot, rainy, cool, then warm again.
- Plants, animals, air, water, and human activities change throughout the year.
- These changes follow a pattern that repeats every year, called seasons.
- Fun example: Seasons are like nature’s calendar, changing pages every few months!
Seasons Journal
- Students keep a journal to record observations of nature all year.
- They note changes in plants, animals, air, water, and human activities.
- Like Saba and Aparna, students share their journal observations.
Classroom Activities: Seasons Chart
Students become nature explorers, creating a chart to track seasonal changes. Let’s join them!
Step 1: Making a Chart for Classroom
- Make a large wall chart with time periods: April–June, July–September, October–December, January–March.
- List themes in rows: plant life, birds and animals, air, heat and light, water and water bodies, human activities.
- The chart helps students see all their journal observations together.
- Fun example: The chart is like a big map of nature’s yearly adventures!
Step 2: Fill the Chart
- Students share journal observations for each theme and time period.
- One student asks the class for observations, like plant life in April–June.
- The class discusses and writes main observations on the chart.
- Each student takes turns filling a box, completing the chart for all to see.
Step 3: Tracking Changes in the Year
- Form five groups, each choosing a theme (e.g., plant life, water and water bodies).
- Each group studies how their theme changed across the year’s time periods.
- Groups create posters showing changes, like leaves blooming or rain in ponds.
- Students present their posters to the class, sharing nature’s patterns.
Step 4: Looking at the Year Together
- Form four new groups, one for each time period (e.g., April–June).
- Each group has one student from each theme to analyze all observations.
- Groups write a short story linking nature and people’s lives for their time period.
- Stories are read aloud to share how nature changes with human activities.
Discovering Seasons
- Students learn nature’s changes repeat yearly, forming seasons.
- India has six seasons: Vasanta (Spring), Grishma (Summer), Varsha (Monsoon), Sharad (Autumn), Hemant (Pre-winter), Shishir (Winter).
- Seasons depend on regional changes in weather, plants, and animals.
- Students can find out the names of seasons in their own region.
Celebrating Seasons
Seasons bring special traditions to life. Let’s see how India celebrates them!
Seasonal Crops and Songs
- Farmers grow different crops in each season, like some in winter and others in summer.
- Some crops need more water, so they’re planted in the rainy season.
- With help from teachers and elders, students learn about local summer and winter crops.
- Many songs in India are connected to seasons, adding joy to these changes.
- Fun example: Seasons are like a festival parade, with crops and songs for each one!
Festivals and Nature’s Rhythm
- Festivals like Pongal and Makar Sankranti celebrate spring and harvests.
- Holi is linked to spring, when flowers bloom, and Diwali to autumn, after crops are harvested.
- Baisakhi, Gudi Padwa, Vishu, and Rongali Bihu mark the new year and harvest in winter.
- Seasons shape what we eat, wear, and do, giving rhythm to our lives.
Notes on the Approach
- Tone: Maintained an engaging, story-driven, and observational storytelling tone, centered on Saba and Aparna’s exploration of nature’s rhythms, connecting seasonal changes to cultural practices like farming and festivals, suitable for Class 5 students.

- Changes around Us in a Day: Day and Night: Saba and Aparna’s reunion, observations (height, hair, guitar, trees), Sun’s apparent movement, nature’s changes.
- Demonstration: Day and Night: Globe and torch activity, Earth’s rotation.
- Changes around Us in a Year: Seasons: Saba and Aparna’s seasons journal, nature’s yearly changes, seasons as repeating patterns.
- Seasons Journal: Journal observations of plants, animals, air, water, human activities.
- Classroom Activities: Seasons Chart: Chart creation, filling with observations, group posters by theme, stories by time period, India’s six seasons (Vasanta, Grishma, Varsha, Sharad, Hemant, Shishir).
- Celebrating Seasons: Seasonal crops, songs, festivals (Pongal, Makar Sankranti, Holi, Diwali, Baisakhi, Gudi Padwa, Vishu, Rongali Bihu) and their seasonal connections.
- Format: Kept the introductory paragraph and your specified headings, with 1–2 subheadings for most sections and the specified steps for Classroom Activities: Seasons Chart, each with 3–5 bullet points in simple language.
