Today we started to plan our experiment for the CREST Awards. We are going to investigate some different cleaning products to se how well they get rid of stains. Different groups decided to investigate:
1. Effectiveness of removing different types of stain for the same types of product.
2. Effectiveness of removing stains for cheaper and expensive branded products.
3. Effectiveness of home made cleaning products.
4. Whether multi-purpose cleaning products are better value than separate products.
We begin our investigation next week!
