# Comparing duration of day in December and May in Changes around us – Class 6 Science Experiment

## Activity Name: Comparing duration of day in December and May in Changes around us

### Activity Description:

The experiment aims to compare the duration of the day in the month of December and May to observe the differences in daylight hours between these two months.

By analyzing the data of sunrise and sunset times, we can determine the duration of the longest day in each month and identify the seasons to which December and May belong.

### Required Items:

Table with the times of sunrise and sunset in December and May for a particular place

### Step by Step Procedure:

1. Obtain a table or dataset that contains the times of sunrise and sunset for a specific location in December and May.
2. Examine the data in column (1) for December and column (2) for May.
3. Identify the day in December with the latest sunrise time and earliest sunset time. Record the corresponding sunrise and sunset times.
4. Calculate the duration of the longest day in December by subtracting the sunrise time from the sunset time.
5. Identify the day in May with the latest sunrise time and earliest sunset time. Record the corresponding sunrise and sunset times.
6. Calculate the duration of the longest day in May by subtracting the sunrise time from the sunset time.
7. Analyze the results to answer the following questions:
• What is the duration of the longest day in December?
• What is the duration of the longest day in May?
• Do December and May belong to the same season? If not, to which seasons do they belong?

### Experiment Observations:

• The duration of the longest day in December is determined by subtracting the sunrise time from the sunset time for that day.
• The duration of the longest day in May is determined by subtracting the sunrise time from the sunset time for that day.
• By comparing the durations of the longest days in December and May, we can observe that the days are shorter in December and longer in May.
• Based on the data, December is associated with shorter duration days in winter, while May is associated with longer duration days in summer.

### Precautions:

• Ensure that the table or dataset used contains accurate and reliable data for sunrise and sunset times in December and May for the specific location.
• Take into consideration any daylight-saving adjustments if applicable to the location.
• Double-check the calculations when determining the duration of the longest day in each month.

### Lesson Learnt from Experiment:

This experiment demonstrates the seasonal variations in the duration of daylight between December and May. It highlights that the days are shorter in December, indicating the winter season, and longer in May, indicating the summer season.

The experiment emphasizes the impact of changing daylight hours on the seasons and helps understand the patterns and differences between winter and summer.
