Session 5: Expanding2

frozen_milk.jpg

This amazing picture is from the really cold winter of 1963.

It illustrates a process called expansion.

When water freezed it expands.

  1. What is going to happen at the ice rink when the water is frozen?
  2. How does the process of turning water in to ice take place?
  3. If there is 1cm of water which expands by 10% what will the new thickness be?
  4. Find out some actual figures from the ice rink to help you
  5. Will there be expansion sideways as well as upwards?

Session 5: All about Ice3

Why do icebergs float in water? This seems difficult to answer because the ice is only frozen water…..lets have a think

  • If you put an ice cube in a glass of water it floats
  • An iceberg is just a massive block of ice so the same rule applies
  • From 50º C to 4º C water gets heavier (i.e. the density rises) but when water gets colder than 4º C it becomes lighter, at 0º C it becomes ice so it is less dense than the water surrounding it. Therefore it floats…

      Session 3: Booking In9

      Ice hockey is a really popular sport. If you want to watch the Telford Tigers you may need to book some seats before the day when the game takes place.

      The ice rink use a computer program to help them work out how many seats have been booked. Today you are going to use a spreadsheet to do this. After you have created a spreadsheet it can work things out automatically. For some spreadsheets to try out click here.

      If you have any questions please add them to the comments section.

      Session 2: Around the rink9

      Some questions…

      • Is it about half a kilometer around the rink?
      • How many times could a speedskater go round the rink in a minute?
      • Why don’t we have a square rink…it would be easier to build?

      Here are some mathematical term to help you with this task

      1. The perimeter is the distance around a 2 dimensional shape such as a rectangle.

      2. The perimeter of a circle is usually called the circumference

      3. To calculate the circumference of a circle you need to use a formula

      3. How fast a skater is travelling can be measured in metres per second (m/s)

      Session 1: Bootiful7

      We were so impressed that you started to work together in teams. You need to remember

      1. The ice rink had to invest in a large stock of boots before it could open
      2. Each pair of boots loses value as it get older. This is called depreciation.
      3. The boot store needs to be well organised.
      4. Staff calculate the value of the boots which may include making an estimate
