THE TAPE CHALLENGE

QUESTION How do the differences in surfaces affect the

adhesiveness of tape?

PURPOSEThe purpose of this project is to determine how the differences in surfaces affect the adhesiveness of tape. This is important to know because we need to know which surface it should be on.

HYPOTHESIS We hypothesize that plastic will keep the

tape on it the longest. We believe this because it is the smoothest surface of all.

PROCEDURE

MATERIALS420 CM OF TAPEA SURFACE (WOOD, GLASS, METAL,

PLASTIC)A SPRING SCALE32 WASHERS

VARIABLESManipulated/independent: surface Responding/dependent: amount of weight

held by tapeConstant: methed of measuring weight held

by adhesive and the size of tape.

STEP-BY-STEP DIRECTIONS1. Cut one piece of tape 21 cm long2. Stick the tape to the plastic with the spring

scale attach3. Hook the large plastic container to the hook of

the spring scale4. Add washers to the container one at a time5. Record amount of weight held6. Repeat steps 1-5 using wood7. Repeat steps 1-5 using metal8. Repeat steps 1-5 using glass9. Repeat steps 1-7 for more trials

CONCLUSIONOur hypothesis was incorrect. The metal

held the more weight than the plastic. Metal held and average of 32.4 washers, glass held 25.6 washers , wood held 16.8 washers, and plastic held 14.4 washers. Plastic was the lowest. We realized that the room temperature may have an affect on the tapes sticking ability. We need to find a way to keep the temperature the same.
