This activity leads students through a hypothetical scenario whereby they are required to devise potential ways to eradicate Super Nits - aka head lice that are resistant to commercially available medicated shampoos. It is centered around targeting nits and head lice at various stages of their life cycle, via manipulating the characteristics required for life - movement, reproduction, sensitivity, growth, respiration, excretion and nutrition. It has been developed to suit the SACE Stage 1 Biology curriculum, although is readily transferable to any curriculum investigating the requirements of life.
In order to suit diverse learning requirements, the activity comes in two versions. The standard version requires students to device a treatment strategy around each of the requirements for life, while a second version asks students to elect two life requirements that could be manipulated. In addition, students are also invited to consider potential limitations and ethical issues around their proposed treatments. Please note - students are not asked provide the chemical constitution of hypothetical products, but rather, are asked to consider potential mechanisms through which treatments could be administered.
