Enzymes in biological detergents

Enzymes in biological detergents can improve energy efficiency by enabling effective cleaning at lower temperatures
This is an IB chemistry internal assessment and needs to follow IB chemistry criteria.
My suggestion is to investigate how temperature affects the rate at which biological detergents work.
You could take some grass and stain identical pieces of cloth and at different temperatures add some biological
washing powder and see how long it takes to clean.
