Sputnik at 50

  • Key Stage 3
  • GCSE
  • Popular Activity
  • Topical

Type: Activity
Learning Strategy: Role play
Topic: Forces

50 years ago the launch of Sputnik 1 heralded a new stage in human exploration and prompted the Space Race – which cost billions but brought with it innovation, excitement and new scientific knowledge.

In this activity students consider whether the cost of the space race can be justified, and whether future space exploration should be funded. They also learn how satellites stay in orbit.

N.B. The activity has now been corrected from the one originally published - see comments

11-16 How Science Works:
11-14 (2008 KS3) – applications and implications
1.2b Examining the ethical and moral implications of using and applying science

14-16 (KS4) – applications and implications of science
4b How and why decisions about science and technology are made,
including those that raise ethical issues, and about the social, economic and
environmental effects of such decisions.

Running the activity

Page one shows the importance of the launch of Sputnik – the world's first artificial satellite, and the catalyst for the Space Race. The world – in particular the USA – was shocked that the Soviet Union was the first to manage such a feat, and genuinely fearful of the military consequences of the Space Age. The launch of Sputnik, and of the craft carrying Laika the dog a month later, prompted the "Sputnik Crisis". It led the US government to invest huge amounts in science education, establish NASA, and redouble it's own efforts in space. The first two websites below are relevant here.

Page two is a timeline of some notable events in space exploration and planned future expeditions. It leads to the task – what do students expect to happen in the next 50 years?

[Note: A more detailed timeline is given separately as an Excel file. Students may notice how fast the USA and USSR progressed in space exploration after 1957, and that the last manned mission to the moon was in 1972. There is no "official" end to the Space Race, but many people regard the first joint mission between the USA and USSR (Apollo-Soyuz Test Project) in 1975 as it's end.]

Page three shows how satellites remain in orbit. You might like to demonstrate swinging a ball on the end of a piece of string.

[Note: escape velocity applies to un-powered objects. Slower moving objects with enough fuel can still escape Earth's gravity. See the third website below.]

Use pages four and five together. Page five introduces four celebrities, each representing a view to consider when making decisions about scientific projects – in this case the question on page four: was the Space Race worth the cost? Can future space exploration be justified?

Get students to sort the evidence cards from page four to represent views A, B, C and D on page 5. Then ask them to plan their contributions to a panel discussion

Sputnik at 50, pretty good. Kids find it a little dull.

I think its a good activity, but kids don't find the subject matter very interesting. I padded out the lesson with a history of the space race, used this acitity to think about the cost. Can be used for a single period at the most. Not a whole lesson activity at all.

I have downloaded many activities from upd8 as reference for writing my lesson plan previous years. Now I refer to it as reference for my student teacher to plan their microteaching. It's more than worth it!

This was done with a year 9 class during the topic gravity and space - it followed on from them designing and making their own satellites, it was a good link and got them thinking about scientific developments.

My Yr9 class really engaged with the possibilities for the future of the space race and came up with some great 1 minute speeches either for or against the space race. This is a good follow on activity after pupils have found out about our previous ideas about the solar system

I downloaded a clip of Sputnik's launch from Googlevideo to complement this activity - the students loved it and wrote some interesting pieces on what they thought about the space race based around this activity.

"y is there no work sheets on there to teach the class". I don't want to be part of the language police, but please try harder. As to what to teach, this is a great activity for giving students a wider view of the Space Race. Any suitable text book or a 5 minute Google search will give you what you want.

My year 9s will be much better prepared for their year 10 skills assessments. Thanks Tony and team.

Well done to Christopher for spotting that our team had a bad physics day. Apologies to alll. A corrected version is on its way.

For information, there are two errors on page 3:

1. The diagrams show two forces. There is only one - towards the centre. The other arrow, showing how the object moves if the central force were removed is not a force.

2. The statements below the pictures are false. If the forces were balanced, then from Newton's first law, the object would be in constant uniform motion in a straight line. It's not! To travel in a circle requires an UNBALANCED central (centripetal) force.

The offending sentence:
The balance of these two forces keeps the ball
travelling in a circle.

Incorrect science when explaining how satellites orbit.
There is only one force. The horizontal motion is not a force.
Will be useful to show to pupils that even adults get it wrong!
