Teaching Outlines
The chapter discusses how the concept of latitude and longitude is used to 'logically' divide the earth. Each location on the earth can be uniquely located, if we have the latitude and longitude of that place
The implications of these two concepts are very important to understand
Key Idea - Latitude
What are latitudes? Why do we need latitudes? What kind of information can we deduce from latitude information?
Learning objectives
Notes for teachers
Activity No 1- Using Marble to study Latitudes
- Estimated Time 1 period
- Materials/ Resources needed Computer/Laptop with Marble educational tool installed. (Ubuntu Kalpavriksha contains Marble) + Projector to show the class
- Prerequisites/Instructions, if any
- Multimedia resourcesSee video on International date line, shown on this page.
- Relevant local connections - people, places and materials
- Website interactives/ links
- Process Demonstrate Latitude on the Marble atlas. Move the earth from west to east to simulate the rotation of the earth. Move the Earth 'top down' and 'bottom up' also upside down to show Arctic Circle in the bottom. Explain 'north' and 'south' are only conventions and not 'up' and 'down'
- What questions can you ask
Why do we need the concept of Latitudes? What physical features depend on latitude? Does weather/climate depend on Latitude? What do we mean when we say 'the sun is above Tropic of Cancer on June' and above 'Tropic of Capricorn' in December? Why does Bangalore have peak summer during March-April, while Delhi has peak summer in June? Are Latitudes lines? Are they parallel lines? Are latitudes parallel to one another?

Key Idea 2 - International Date Line
Why do we need a International Date Line?
See http://en.wikipedia.org/wiki/Date_line#mediaviewer/File:Dateline-animation-3deg-borderonly-180px.gif
Learning objectives
To understand need for an arbitrary 'date line' which begins a 'new day' at a artificial 'longitudinal' line. To understand why this line is not 'straight' but changes in many places
Notes for teachers
This is a very difficult concept to understand and may need a physical simulation with a globe for students to understand.
The idea of time varying across longitudes as well as time zones need to be well understood before coming to date line.
A video explaining the concept of date line
Activity No 1 - Using Marble educational software to explain the International Date Line
- Estimated Time 1 period
- Materials/ Resources needed Computer/Laptop with Marble educational tool installed. (Ubuntu Kalpavriksha contains Marble) + Projector to show the class
- Prerequisites/Instructions, if any
- Multimedia resourcesSee video on International date line, shown on this page.
- Relevant local connections - people, places and materials
- Website interactives/ links
- Process Demonstrate the International date line on the Marble atlas. Move the earth from west to east to simulate the rotation of the earth. Explain why the date line is needed and why it is not 'straight'
