pumpkin seeds and the pinning capacity.
It shows that the higher the volume,
the higher the pinning capacity.
It means that the volume controls the
number of pins needed to use for the
cork board. The pistachio is bigger than
the pumpkin seeds so it takes less
volume for the pinning capacity. Methodology. •Pumpkin Seeds (4.5 g./pack) 20 pieces 8-width 11-length
•Approximately 8x11 inch plywood
•Molding (8x11 inches) (0.5 inch thick)
•Glue or Rubber Cement (250g./pack)
•Mortar and Pestle
•Saw & Nails
Generalization/Conclusion From the results of the study, we conclude that pumpkin seeds have the potentials of a corkboard filling. The study proved that pumpkin seeds could be a substitute material in making a corkboard because of its physical properties like compressive strength are similar to those of a cork which is to withstand force from a push pin or thumbtacks. This study is to test the physical properties of a pumpkin seed as a cork board such as compressive strength that can withstand the pressure and force of sharp objects like thumbtacks. This study is also significant because due to its similar properties of cork, it can be used as an alternative material in making a bulletin board which can be used in a cheaper and practical way. • 1)Decide how big you would like your corkboard to be. Measure the space where you plan to hang it, then plot these measurements. (8x11) using the tape measure and pencil and carefully cut it to the size using the saw.
2)Before putting the pumpkin seeds, use the mortar and pestle to crush the seeds into bits
3)Apply glue or rubber cement to the plywood, then pour the crushed pumpkin seeds evenly. After that, let it dry for 30-60 minutes
4)Measure the molding to match the length of the plywood on all four sides. Cute the molding to proper length, then saw the edges
5)Connect the molding with the nails and rubber cement. Then nail and glue on to the board. You can paint, stain or decoupage the molding frame to add special interest.
What you need: We recommend that to have a further study or research of pumpkin seed as a cork board filling, to discover a more creative and systematic way in making a cork board out of pumpkin seeds or any other material similar to a cork such as pistachio because like a pumpkin seeds,
it is encased in a shell but a harder
