  • Fe2+ is called Iron(II) this will combine with O2- oxide as FeO Iron(II) Oxide (black iron-oxide)
  • Fe3+ is called Iron(III) this will combine with O2- oxide as Fe2O3 Iron(III) Oxide (red rust)
  • S2- is called the Sulphide Ion and is different to SO42- the Sulphate Iron

    Term 1 Week 3

     Paper Dart Testing

    In groups of three, you are going to try making a range of different paper darts and test how they perform in practice.

    You are going to change the type of dart you make,
    and also the length of the dart.
    To test the darts, you will throw them in a repeatable way,
    and measure two things.
    You are going to both measure the distance it travels before it
    touches the ground (not necessarily where it lands)
    and the time it spends in the air before it hits the ground.

    Below are some dart designs, choose two to test.
    Basic Dart

    Flat Nose Dart

    Glider Dart

    Dart Floating
