QUESTIONHow do differences in surface

affect the adhesiveness of tape?

The purpose of this project determine how do differences

in surfaces affect the adhesiveness of tape. This is important to know because

what if you are going to hang a poster. You need to know

which surface it should stay on.

PURPOSE

HYPOTHESIS

We hypothesis that the plastic will keep the tape on it longest . We believe because it is the smoothest surface of all.

Procedure

Materials

• 420 cm of tape • Glass surface• Plastic surface• Wood surface• Metal surface• Spring scale• Metal washers used as weights

variables

Manipulated/Independent: the surface. Responding/dependent: amount of weight

held by tape.

Direction

1. Cut 21cm piece of tape2. Stick the tape to plastic with spring scale3. Spring scale attached4. Hook the large plastic container to the

hook of the spring scale5. Record the washers held6. Repeat steps 1-5 on metal7. Repeat steps 1-5 on wood8. Repeat steps 1-5 on glass9. Repeat steps 1-8 for four more trails

Conclusion

Our hypothesis was incorrect. The metal held the most weight instead of plastic. Metal held an average of 32.4 washers, glass held 25.6, wood held 16.8, plastic held 14.4. Plastic was the lowest. We realized that the room temperature may have an effect on the tape’s sticking ability. We need to find a way to control the room temperature for all the trials.
