AO2 (6 marks)
Credit up to two marks for each description in relation to the scenario.
For example;
- Refinement would mean Louis considered how to conduct the
experiment on rats with minimal pain (1) such as using the bell to
disturb sleep instead of electric shocks (1).
- He would have made sure he provided a suitable habitat for the
rats in both conditions (1) and that the 25g of food was an
adequate amount to maintain a healthy weight (1).
- Reduction requires Louis to use as few rats as possible in his
experiment, so he used only nine (thirteen in total) rats (1) which
would be the minimum needed to reliably test sleep disturbance
and appetite (1).
Look for other reasonable marking points.
