Working Scientifically

To complete our materials topic, we  looked into the work of Patsy Sherman, the scientist who discovered and developed Scotchgard. 

Today we carried out a range of tests to see what kind of material it was most effective on, which stains it was most effective on and how many sprays of Scotchgard you should use to get the best affect. 

We evaluated our fair tests, noting any variables we couldn't control and we were also aware of how scientifically we were working.
