Lesson Plan of Satellites (Space & satellites)
General Science Grade VI
Students’ Learning Outcomes
· Define the term satellite.
· Describe the uses of various satellites in space.
· Explain that how do satellites tell us where we are.
Information for Teachers
· Satellite: bodies that rotate in orbits around other bodies of greater mass under the influence of a gravitational field. For example, the moon is a natural satellite of the earth. Satellite which are used for relying radio, television and telephone signals around the earth are artificial earth satellites. They are called communication satellites.
· Satellite is an object which revolve around some massive body e.g. earth around the Sun.
· Moon is a natural satellite of the earth.
· Artificial satellite is a man-made space craft manufactured on this earth and sent into an orbit around the Earth.
· Artificial satellites are used for different purposes and they can be categorized as:
1. Research Satellites: Measure major properties of outer space.
2. Weather Satellites: Helps scientists study weather designs and prediction the weather.
3. Communication Satellites: Deliver a worldwide link up of radio, telephone and television.
4. Navigation Satellites: are mainly envisioned to help regulate the positions of aircraft, ship and submarines with great correctness.
5. Earth Observation Satellites: are used to map and display our planet’s resources an ever-changing chemical life changing.

Worm up activity
· Ask some questions to assess the students’ previous knowledge.
v Have you ever seen the booster on the roofs of high buildings?
(Expected response: Yes)
v Ask the students, have they seen live cricket or hockey match on TV?
(Expected response: Yes)
v How are we able to watch live cricket match?
(Expected response: With the help of a satellite)
v There are some man made satellites sent into the space orbiting the Earth for navigation, communication, military purpose. Do you know some other satellites?
(Expected response: For weather forecast etc.)
· Divide the class in five groups and provide them pictures of artificial satellites.
· Students will be asked to discuss in groups about the uses of different artificial satellites.
· Involve them in discussion to tell the uses of these satellites.
· Make the following chart on the board and have the students copy and complete the table on their notebooks working in groups
· Observe their response and appreciate them.
· Recap the uses of artificial satellites.
· Ask the students which satellite tells us:
v Where we are?
v Where am I?
v I want to go to the moon how can I get there?
· Involve them in discussion to answer these questions.
· After recording their response, tell them that Navigation Satellite is the satellite which helps us to answer the questions about our position.
· Navigation Satellites were developed in the late 1950’s as a direct result of ships routes, so that one can know exactly where they were at any given time, in the middle of the ocean or out of sight of land.
Assess the students by asking following questions:
v How many types of satellites are there?
(Expected response: two; natural and artificial)
v What type of satellite is used for audio and video communications?
(Expected response: communication satellite)
· Collect some pictures of satellite and paste them on a color chart paper.
