This project involves creating glue from cornstarch, potato starch, and flour, and testing their adhesive strength on wood samples. Students will learn about the properties of different starches and their effectiveness as glue.
If different starches are used to make glue, then the cornstarch glue will have the strongest bond due to its thickening properties.

Prepare three separate glue mixtures using cornstarch, potato starch, and flour.
Mix each starch with water to create a paste-like consistency.
Apply each glue to separate pairs of wood samples using a brush.
Press the wood samples together and allow them to dry for 24 hours.
Test the strength of each bond by trying to pull the wood samples apart.
Record the force required to break each bond.
Repeat the experiment three times for each starch type.
Analyze the data to determine which starch creates the strongest glue.
Cornstarch glue is expected to provide the strongest bond due to its thickening and adhesive properties.

Ensure proper ventilation when testing the glue strength to avoid inhaling any dust or particles.
Create a bar graph to display the strength of each glue type.
Include pictures of the testing process and results.
Discuss the properties of each starch and their impact on glue effectiveness.
Different starches have unique properties that affect their adhesive strength.
Ensure proper mixing and drying time for effective adhesion.
Yes, but ensure consistency in size and surface for accurate comparisons.
