I am working on this assignment with a group. We are supposed to come up with 5 ways that chemical technology is used in the home.
What I need help with is to discuss the following:
1. cleaning products
2. personal care products.
I also need help coming up with an introduction to the essay. Obviously I don’t know what they are going to include in the essay but just a general introduction and we can add the remaining.
Basically it should be about 3 paragraphs:
1. introduction
2. discuss chemical technology #1 – cleaning products
3. discuss chemical technology #2- personal care products
