Page 34 Reading graphs · Tell me
Q.Observe the graphs given below and answer the questions.
Values read from the graphs (temperature values are read by eye, so they are approximate):
| Week | Max (°C) | Min (°C) | Range (°C) |
|---|---|---|---|
| 15th to 21st June | 35 | 20 | 15 |
| 22nd to 30th June | 33 | 20 | 13 |
| 1st to 7th July | 31 | 21 | 10 |
| Date | Rainfall (mm) |
|---|---|
| 17th June | 50 |
| 18th June | 60 |
| 19th June | 70 |
1.Identify the type of graph in figure no. 4.6 (a).
Ans: The graph in figure no. 4.6 (A) is a multiple line graph. It compares two variables, the maximum and the minimum temperature, on a single graph.
2.In which week is the temperature maximum?
Ans: The temperature is maximum in the first week, from 15th to 21st June, when the maximum temperature is about 35 °C.
3.In which week the range of temperature is maximum?
Ans: The range of temperature is maximum in the first week, from 15th to 21st June. Range = maximum temperature − minimum temperature = 35 °C − 20 °C = 15 °C. This is more than the range in the other two weeks.
4.Write the scale of the graph shown in figure no. 4.6 (b)
Ans: The scale of the graph in figure no. 4.6 (B) is Y axis 1 cm = 10 mm.
5.How much is the rainfall on June 18th?
Ans: The rainfall on 18th June is 60 mm.
6.State the difference in the amount of rainfall between 17th June and 19th June.
Ans: The rainfall on 19th June is 70 mm and on 17th June it is 50 mm. So the difference is 70 mm − 50 mm = 20 mm.
Tell me.
Model answers. Your own answers will depend on the field visit you have been on.
Where have you been for a field visit?
Ans: We went for a field visit to a nearby lake and bird sanctuary.
In which direction is that place from your school?
Ans: The place is in the north-east direction from our school. We found this using a compass.
Which means of transport did you use to reach that place?
Ans: We travelled there by school bus.
Which objective of yours is achieved by visiting that place?
Ans: We observed the natural surroundings, noted down data and observations first-hand, and understood how water bodies, plants and birds are connected.
Where else would you like to go for a field visit?
Ans: I would like to visit a weather observatory or a science centre to see how weather instruments work.

A)Depict the following elements in the world map with a legend.
1) The Equator and the Prime Meridian 2) The Australian continent 3) The Atlantic Ocean 4) India
- The Equator is the 0° line of latitude. It runs east to west across the middle of the map and divides the Earth into the Northern and Southern Hemispheres. It is shown with a red dashed line.
- The Prime Meridian is the 0° line of longitude. It passes through Greenwich and divides the Earth into the Eastern and Western Hemispheres. It is shown with a green dashed line.
- The Australian continent lies in the Southern Hemisphere, between the Indian Ocean and the Pacific Ocean. It is coloured orange.
- The Atlantic Ocean lies between the Americas on the west and Europe and Africa on the east. It is shaded blue.
- India lies in the Northern and Eastern Hemispheres, in the southern part of Asia. It is coloured purple.
B)Construct a simple bar graph based on the data given below.
| Taluka | Ambajogai | Dharangaon | Pandharpur | Kamti |
|---|---|---|---|---|
| Rainfall in mm (Year 2024) | 622 | 559 | 732 | 845 |
Steps to draw:
- Draw the X axis (Taluka) and the Y axis (Rainfall in mm).
- Choose a scale for the Y axis: 1 cm = 100 mm.
- Draw bars of equal width with equal gaps for each taluka. The height of each bar shows its rainfall.
- Write the title, the axis labels and the scale on the graph.
C)Construct a line graph based on the data given below.
| Taluka | Ambajogai | Dharangaon | Pandharpur | Kamti |
|---|---|---|---|---|
| Temperature Degree C° (March 2024) | 34 | 35 | 37 | 30 |
Steps to draw:
- Draw the X axis (Taluka) and the Y axis (Temperature in °C).
- Choose a scale for the Y axis: 1 cm = 5 °C.
- Mark a point for the temperature of each taluka.
- Join the points with straight lines and write the title, the axis labels and the scale.
Activity:Prepare a questionnaire for a field visit to a place in your surrounding area.
Questionnaire: Field Visit to the Local Market
- What is the name of this market and where is it located?
- In which direction is the market from our school?
- Since when has this market been functioning?
- On which days and at what timings is the market open?
- Which goods (vegetables, fruits, grains, etc.) are sold here?
- From which villages or places do these goods come?
- Which means of transport are used to bring the goods to the market?
- How many shops and workers are there in the market?
- What problems do the traders face (space, parking, waste, rain)?
- What is done with the waste and the unsold goods?
- How does this market help the people of the surrounding area?
- What suggestions do you have to improve the market?
Activity:Enlist the modern techniques useful for reaching an unknown place properly.
- Google Maps (digital maps and online mapping) shows the route, the distance and the travel time to a place.
- GPS (Global Positioning System) uses satellites to find our exact location and guide us on the way.
- Mobile navigation apps give turn-by-turn voice directions while we travel.
- Satellite images and street view let us see the place and its surroundings before we reach it.
- The digital compass in a mobile phone helps us decide directions.
- Sharing live location with family or friends helps them find us and helps us find them.
- Online timetables and travel apps help us choose a bus, train or other transport to reach the place.
