 * What kind of glue will hold two pieces of wood under the most weight?**

There's a reason professionals don't fix their airplanes with glue sticks. Different glues work together in different ways, either using polymers that chemically bond to each material or mechanical bonding through the imperfections on the surface. Not to mention that some adhesives work better on some materials than others. So the question is, which piece of wood will hold the most weight when suspended?

Need additional research on this topic. Ms. Miller

HYPOTHESIS: The e6000 glue will hold the most weight.

Needs to be more descriptive. Ms. Miller

Materials: (Prices according to Amazon.com) -Elmer’s School Glue $1.57 -Loctite brand superglue $3.47 -e6000 craft adhesive $2.97 - 1x2 blocks of wood (9-12) (A 1x2x12 block of balsa wood is $11.97) -cup hooks (18-24) Pack of 40 costs $3.48 -weights $10.50 -string $1.99 -padding $25.99 -drill $29.88

Total: $91.82

Procedure: 1. Using the drill, screw in 1 cup hook to each of the wood blocks 2. Apply a thin coat of Elmer's glue to one block and attach it to another block. Repeat this until you have three sets of blocks. 3. Apply a thin coat of superglue to one block and attach it to another block. Repeat this until you have three sets of blocks. 4. Apply a thin coat of e6000 to one block and attach it to another block. Repeat this until you have three sets of blocks. 5. Thread the string through each of the hooks on the blocks. Thread increasing weights onto one of the strings and let it hang, adding more and more weight until the wood blocks break off of each other. 6. Record your observations.

what kind of weights are you using? Ms. Miller

How long will you let the glue dry before conducting the experiment? -Lily Maxwell Make sure to specify the amount and placement of the glue you will be using on each to keep it constant. -Lily Maxwell Have you considered the factor of humidity? If it is more humid or less humid the glue could stick better or worse-Casey Fox How much weight will you be adding each time?-Casey Fox What type of string do you plan on using? Depending on the string's strength, it might break from the mass of the weights. (Kaitlyn Olsen) What's the reasoning behind your hypothesis? -Natalie Kerr and Courtney Stolba Is there any other types of glue that you may consider using? Why did you chose the brands/types of glue that you did? -Natalie and Courtney I love your idea I think it will be very successful, where are you planing on purchasing your materials?- Sarah Baer
