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.

Disha is on a mission to solve food mysteries, from why her uttapam spoiled to how we keep food fresh! This chapter follows her adventure, learning how food changes, how we preserve it, and how it helps our bodies stay healthy. Let’s join Disha and her notebook to crack these tasty cases!

Food Spoilage

Disha’s forgotten tiffin box sparks a mystery about why food goes bad. Let’s follow her clues to find out!

The Forgotten Tiffin Box

• Disha found her lunch box at school, forgotten since Friday, with uttapam inside.
• Opening it, she smelled a foul odour and saw colored patches on the uttapam.
• She wondered what happened to her favourite food, starting a mystery.
• Disha became Detective Disha, eager to investigate food spoilage.
• Fun example: Disha’s uttapam turned into a smelly puzzle waiting to be solved!

Mystery #1: What Made My Uttapam Spoil?

• Disha asked her Anna, Aditya about the colored patches on her uttapam.
• Anna explained they’re mould, caused by tiny living things called microbes.
• Microbes are so small you need a microscope to see them, changing food’s taste and smell.
• Some microbes help make curd, but others spoil food like uttapam.

Finding #1

• Microbes are everywhere—in soil, water, air, plants, animals, and inside us.
• They grow on food, forming mould patches like on Disha’s uttapam.
• A mould patch is a colony of thousands of microbes together.

Mystery #2: Why Do Some Foods Spoil Faster?

• Disha noticed bread left out for two days had mould, but Paati’s pickles lasted months.
• Anna said microbes need moisture, air, and warmth to grow quickly.
• Pickles stay fresh because oil keeps air away, slowing microbes.

Finding #2

• Keeping air and water away from microbes stops them from spoiling food.
• This helps food stay fresh for longer.
• Methods like using oil slow down microbe growth.

Food Preservation

Disha wants to know how to stop food from spoiling. Let’s see what she learns at home!

Mystery #3: How Do We Save Our Food from Spoilage?

• Disha looked around her house for ways to keep food fresh.
• Her family used different methods to stop microbes from spoiling food.
• Each method keeps food safe by stopping microbe growth.

Let Us Observe: Drying and Dehydration

• Disha saw Amma and Appa drying chillies in the sun on the balcony.
• Drying removes moisture from chillies, so they last a whole year.
• Without water, microbes can’t grow and spoil the food.
• Fun example: Drying chillies is like squeezing out water to keep microbes away!

Finding #3

• Drying food in the sun removes moisture, stopping microbes.
• This keeps food like chillies fresh for a long time.
• It’s a simple way to preserve food.

Let Us Observe: Pickling and Oiling

• Paati poured mustard oil into a jar of pickled green mangoes.
• Oil stops air from reaching the pickles, keeping them safe.
• This prevents microbes from growing and spoiling the food.

Finding #4

• Adding oil to pickles keeps air out, stopping microbe growth.
• This helps pickles stay fresh for months.
