Conclusions - Have group draw conclusions based on testing. They divide the report and present orally to class - Reports are displayed. Students can add materials to be tested. Students can put materials in baggies and place in freezer to see what effect cold has on the adhesive. Students can use lamps or hair dryer to heat the adhesive and then retest.
Students can make their own adhesives using skimmed milk and vinegar.
There are four tests scientists use to see how sticky an adhesive is. Choose only one for your experimentation. We can come to the same conclusions by using everyday materials. Write number of pennies on data sheet and repeat experiment for each tape. Repeat experiment for each tape.
