Planet earth and the universe

Module 37

Investigating the mysteries of outer space

Activity:

Investigating the mysteries of outer space and talking about satellites [lo 1.1, 1.3, 3.1]

Up ... up ... up...

I go

looking down on Earth

below

the moon I pass

with daring swing

and over there ...

a shiny thing ...

a star!

and many millions more

I dodge the planets one by one

here’s Venus

oh it’s really fun!

and Pluto there

the smallest one

I glide my rocket

down a sunbeam

and land in my bed ...

it was just a dream

A.V

Illustrate the poem.

It is every child’s dream to travel into space but few of us have the wonderful opportunity that Mark Shuttleworth had when he was able to go into outer space in 2002. But we can find out much about space by using a telescope.

The telescope

An Italian named Galileo Galilei made a telescope with which he could look at distant objects in 1609. He found that the brightly lit area of the sky that we call the Milky Way was actually composed of a myriad of stars. He could also see mountains and craters on the surface of the moon.

Make your own telescope from waste materials and then carry out the following assignments:

  • Use your telescope to look at the stars at night.
  • Do the same during the day but remember not to look directly at the sun as this can seriously damage your eyes.
  • You and your friends must now make up a story based on anything that you have seen through your telescope. This does not have to do with the stars but you may write about anything else. Give the class some feedback by means of role-play. Try to be creative!

Here are some ideas:

  • one group can be tourists
  • another group can be a sports team
  • another group can be television actors who act during a news bulletin
  • another group can present their story on the radio.

Space

We live below a very deep layer of air that we call the atmosphere. The atmosphere provides us with oxygen to breathe; it keeps us warm and protects us from the rays of the sun. If we travel away from the earth through the earth’s atmosphere, the air becomes thinner and thinner and it becomes very difficult to breathe. At a height of about 10 km it is not possible to breathe without extra oxygen. At a height of 160 km above the earth’s surface there is hardly any air at all. Here we really are on our way into space!

In space there is no atmosphere. Sound does not travel and weather conditions, as we know them on earth, are unknown. Space begins where earth’s atmosphere ends. But we do not know where space ends. Spacecraft have already travelled from earth and deep into the universe, but have not yet reached any of the stars that are very far away. These stars are millions of kilometres away.

Assessment

LEARNING OUTCOME 1: SCIENTIFIC INVESTIGATIONSThe learner will be able to act confidently on curiosity about natural phenomena, and to investigate relationships and solve problems in scientific, technological and environmental contexts.

Assessment Standard

We know this when the learner

  • plans investigations;

1.3 evaluates data and provides feedback on observations.

LEARNING OUTCOME 3: SCIENCE, SOCIETY AND THE ENVIRONMENTThe learner will be able to demonstrate an understanding of the interrelationships between science and technology, society and the environment.

Assessment Standard

We know this when the learner

3.1 understands science and technology in the context of history and personal knowledge.

Memorandum

Hints for this module:

  • Always keep many old magazines in class, so that learners can cut pictures from them
  • Show them many pictures from books and magazines
  • Let the learners experience the subject matter practically
  • Encourage them to be creative when they do assignments or work in groups
  • Try to create activities whereby they can discover things themselves
  • If possible, show videos. Learners learn a lot through visual observation

The mystery of outer space

Read the poem to the class and let them draw a picture. Let them look for more poems or reports on space that they can read to the class.

The telescope

Make your own telescope from waste material. You can get ideas in various books

Space

  • Try to show a video about space.

what about nanotechnology for water purification
RAW Reply
please someone correct me if I'm wrong but I think one can use nanoparticles, specially silver nanoparticles for water treatment.
Damian
yes that's correct
Professor
I think

Nasa has use it in the 60's, copper as water purification in the moon travel.
