This column provides an inside look at the marvels of engineering in everyday life. This month's issue takes a closer look at adhesive bandages.
A selection from Science Scope—April/May 2012
Before coming across this article i would've never thought about doing such activity, I found this activity to be really creative. This activity allows students to use engineering concepts to figure out what band-aid is the best one for purchase and allows students to experiment, explore and compare the degree of waterproofing on different types of bandages. They also make/engineer a knuckle bandage that does not leak. I think this is a great activity for the classroom because it is very hands-on.
This interesting article has the history of bandages and some intriguing activities to explore. Students compare the degree of waterproofing on different types of bandages and then engineer a knuckle bandage that does not leak.

Students are challenged to design an adhesive bandage that will stick to their knuckles and keep the knuckles perfectly dry. Students first explore several product bandages to look at the different kinds of material they are made of. They will look at the effect of water as well the design for a rather difficult part of the body. This engaging 5E lesson cycle activity includes the history behind bandages as well a student worksheet to keep them engaged. Costs are low and interest is high. This looks like a fun challenge for students.

The authors present a 5E lesson where students test adhesive bandages and then design a bandage that will keep a wound on a knuckle dry. The activity worksheet is well written and provides students with all of the background they need to be successful. My middle school students enjoyed designing their own bandages and found several ideas that worked really well.
This lesson is easily adaptable to all ages and provided students with a unique opportunity to practice the skills of providing a solution to an idea that needs to be tested and improved upon.
