Lesson Plan of Artificial Satellites together with Geostationary
General Science Grade VI
Students’ Learning Outcomes
· Describe artificial satellites together with geostationary satellites.
· Investigate how artificial satellites stimulate got improved our cognition nearly infinite together with are used for infinite research.
· Explain the primal milestone inward infinite technology.
Information for Teacher
· The objects revolving to a greater extent than or less a massive trunk due to its attraction or gravity is called “Satellite” of that body. E.g.
1. Planets are satellites of the Sun.
2. The Moon is satellite of the Earth.
· Artificial satellites are human-built objects orbiting the Earth.
· Satellites are the objects which are launched inward infinite past times rockets.
· Like the moon, they are held inward scope past times the gravitational line of the Earth.
· The higher the satellite, the slower is the speed together with longer is the fourth dimension required to consummate its ane orbit.
· Satellites tin live launched into 2 orbits similar Polar together with Equatorial orbits.
· Polar orbit:
o A polar scope is a satellite scope that passes over or real unopen to both poles of the Earth.
o Satellite inward polar scope tin divulge all points on the Earth.
o These orbits are used for observation all satellites.
· Equatorial Orbit:
o A satellite inward equatorial scope flies along the job of the Earth’s equator.
o To snuff it into equatorial orbit, a satellite must live launched from a house on earth unopen to equator.
o Equatorial scope are useful for satellites observing weather condition patterns.
· Geostationary Satellites:
o The menses of a geostationary satellite is the same every bit that of the earth, together with then the satellite appears to live stationary at ane house all the time.
o The scope of sec geostationary satellite is likewise called “geostationary orbit”.
o The GPS (global positioning system) uses 24 satellites.
o They scope the earth inward half dozen sets of orbits.
o At whatever time, a receiver on the reason tin have the signal from their satellites.
o GPS helps the vehicles together with ships to stimulate got best.

Worm upwardly activity
· Ask the students nearly artificial satellites, where exercise they exist? And the run of sending upwardly these satellites inward infinite to assess the students’ previous knowledge.
1. What are artificial satellites?
(Expected response: Man-made objects sent into infinite orbiting the Earth)
2. Why nosotros launch artificial satellites?
(Expected response: To snuff it up-to-date data from our surroundings)
3. How inward ancient fourth dimension people snuff it guidance to go from ane house to another?
(Expected response: With the assistance of a magnetic compass)
· Ask the students that whether they mightiness stimulate got seen e'er a motion painting or clip regarding spaceship/satellites, how are they existence launched into space?
Development
Activity 1
· Tell the students that inward the modern era novel technologies are introduced.
· Artificial satellites are ane of them
· To empathise the catch the drive of satellites to a greater extent than or less the Earth, nosotros volition exercise an activity.
· Attach an object amongst a string together with ensure that it has been tied properly.
· Whirl the object inward a circular path.
· Ask them why the object is moving inward the circular path?
· After taking their response, say them that nosotros require a forcefulness which tends to displace the objects inward circular path.
· In this instance amongst the assistance of our mitt nosotros are applying such forcefulness to displace the object inward the circular path.
· With the assistance of this illustration clear the concept nearly the displace of satellite to a greater extent than or less the Earth.
· Give cognition to the students that an object nether the activity of gravity, revolves to a greater extent than or less the earth inward a fixed path.
· Img
Activity 2
· Divide the cast inward groups together with enquire them to read the fabric nearly artificial satellites from their textbooks or library books.
· Make the next tabular array on the board together with enquire the students to re-create it on their notebooks.
Artificial Satellites | Advantages |
1.Research Satellites | |
2.Weather Satellites | |
3.Communication Satellites | |
4.Navigation Satellites |
· Each grouping volition give the tabular array from the data given inward the textbook.
· At the cease instructor volition summarize the activity.
· Summarize activity past times teacher:
1. Research Satellites: Measure major properties of outer space.
2. Weather Satellites: Helps scientists report weather condition designs together with prediction the weather.
3. Communication Satellites: Deliver a worldwide link upwardly of radio, telephone together with television.
4. Navigation Satellites: are mainly envisioned to assistance regulate the positions of aircraft, ship together with submarines amongst bully correctness.
5. Earth Observation Satellites: are used to map together with display our planet’s resources an ever-changing chemic life changing
Activity 3
· Make a chart on primal milestones inward infinite applied scientific discipline from the scientific discipline textbooks or books from library.
Name of satellite | Launching date | Purpose |
US Tinos 1 | April 1, 1960 | To report weather condition conditions |
· Display the chart inward the cast together with enquire the students to read together with Federal Reserve annotation their observations.
· Involve the students inward give-and-take nearly the primal milestones inward infinite technology.
Sum upwardly / Conclusion
· Conclude the lesson past times recapping the artificial satellites together with their kinds.
· Summarize the primal advantages of some artificial satellites.
1. Communication satellites: these satellites assistance to transmit the communication signals from ane house to some other e.g. communication through mobile phones together with telephones.
2. Weather satellites: these types of satellites assistance us to have up-to-date data nearly weather condition conditions.
3. Navigation satellites: these type of satellites are used past times ships to navigate their directions through GPS (Global positioning system)
4. Astronomical satellites: These types of satellites stimulate got abrupt photographs of the objects exterior the earth’s atmosphere.
Assessment
· Assess the students’ agreement past times bespeak the next questions:
1. Name dissimilar artificial satellites.
(Expected response: weather condition satellites, communication satellites, together with astronomical satellites)
2. What are weather condition satellites?
(Expected response: at that spot are the satellites which assistance us nearly the forthcoming changes inward weather)
Follow up
· Ask the students to brand a poster on artificial satellites to high lite their advantages.
