Glass Worksheets KS3/4

Process

1. Hold a discussion about money and budgeting. Ask students what they see their parents doing at home. Discuss ways of saving money, like going to different supermarkets for different offers, or comparing options using a price comparison website.
2. In groups ask students to brainstorm how many reusable products and their disposable options are available. Ask groups to share. Expect items like face masks, nappies, period products (see our pages on Reusable Period Products), handkerchiefs. More unusual ones might be ear protection, paper towels, toilet paper (family cloths are the reusable option!).
3. Ask the groups to choose one item to compare. Using computers and iPads ask students to start researching the costs of reusable and disposable items. Supermarket websites will have costs for the most easily available options like disposable nappies and period products. Specialist websites will sell reusable options.
4. Ask groups to compare the costs over a certain time period. This could be for the first 3 years of a child’s life for nappies or the period of time a person menstruates (about 40 years).
5. Ask students to prepare a presentation to the rest of the class comparing the costs. Students could also prepare a leaflet for the public or their families. They could even ask the school to send information home with families if they wished to.
6. Make sure students understand that the cost of products often does not represent their environmental cost, i.e. the cost of disposal of the item – e.g. nappies end up in black bin bags, which are burnt for energy in Devon. This is a very expensive process. Reusable products are better for the environment and can help save money too.
