Always remember what CORMs stands for before answering questions in this format:


 * C** - **__CHANGE__**: what is your IV?
 * O** - **__ORGANISM__**__:__ what organisms will be involved and what similarities do they need to have e.g. same sex, age, health, etc?
 * R** - **__REPEAT__**: ALWAYS REPEAT (this improves RELIABILITY)
 * M1** - **__MEASURE__**: what is your DV and how will you measure it?
 * M2** - More detail on your DV
 * S1** - What needs to be kept the **__SAME__**, i.e. your CVs?
 * S2** - You need to identify and control at least two CVs, but the more can identify, the better

Other examples of CORMS questions include:
 * 1) The instructions on a packet of seeds read: “to obtain the most growth sow seeds 10 cm apart”. Design an investigation you could carry out to find out if the distance seeds are sown apart affects the growth of the young plants they produce. (6 marks)
 * 2) Transpiration is the evaporation of water from the surface of a plant. Describe an investigation you could carry out to find out how temperature affects the rate of transpiration in a leafy shoot. (6 marks)
