Personal Care Products
This module can be included as part of the nanotechnology elective unit in middle school science or can be taught in isolation as an introduction to Consumer Science, in particular to give students an awareness for making decisions about nano products in the market place. The focus is on personal care products but could easily be extended to cover other consumer products such as sporting equipment, food, electronic goods, clothing etc.
Module Guide
In this module students will first learn about awareness and how to make informed decisions when it comes to personal care products, including undertaking an activity to learn about product labelling, as well as an experiment to make a cream to learn about ingredients
They will then learn about ‘nano’ products, including the benefits of nano products, illustrated using an experiment comparing nano and normal sunscreen, as well as issues surrounding safety and informing the public.

Activity 1: Reading Labels
To make informed decisions, we have to know what we are buying and what we actually need. In the first activity students create a spreadsheet and collect 10 labels from personal care products and cosmetics and record details of main ingredients. The aim of this is to learn about the common ingredients in products like shampoos, creams, gels, sunscreens.

Activity 3: How does sunscreen work?
In the second part of the module students are introduced to some examples of personal care products that contain nanotechnology. To learn about how nanotechnology can change/improve a product, nano sunscreen is used as an example. Students first undertake a research activity to learn about sunscreens and how they work.
