Then the cost per unit was multiplied to the amount of units used to enable the researchers to get the expenses based on the setup of the project study.The total cost of the five (5) polymer products amounted to P27. 82. The cost of each polymer product was P 5. 56. 28 CHAPTER 5 SUMMARY OF FINDINGS, CONCLUSIONS AND RECOMMENDATIONS SUMMARY OF FINDINGS Based on the observation, homemade bouncy polymer can be created by mixing Borax dissolved in water, glue diluted in water an d cornstarch. The characteristics of the polymer depend on the amount or ratio of the solution. The more glue solution is added the more elastic the polymer is while the more Borax solution is added the more watery it is. All the Polymers weighted the same, 40 grams.Polymer 1 has the highest volume with 90 ml. Polymer 5 has the highest density with 0. 53 g/ml. Polymer 1 has an average bounce/return height of 6. 4 cm; an average stretch distance of 43. 6 cm; and, an average roll distance of 84. 8 cm. Polymer 2 has an average bounce/return height of 5. 0 cm; an average stretch distance of 34. 8 cm; and, average roll distance of 36. 6. Polymer 3, 4 and 5 did not bounce at all; was not possible to be stretch; and, did not roll at all. The total cost of the five (5) polymer products amounted to P27. 82. The cost of each polymer product was P 5. 56.CONCLUSION Based on the results and findings of the project study, the following conclusions were obtained: 1. It is possible to make a homema de bouncy polymer using PVA glue and cornstarch with the addition of Borax dissolved in water. 29 2. Polymer 1 with the ratio of 1:5:1 (Borax solution:glue solution:cornstarch) produced the best homemade bouncy polymer. It has the highest average bounce/return, highest average stretch distance and highest average roll distance. 3. Varying ratio of the ingredients, Borax solution and glue solution, affect the physical characteristics of the homemade bouncy polymer.Using less borax will produce a goopier type of ball while adding more glue for a slimier ball. RECOMMENDATIONS Making a homemade bouncy polymer produced a positive result. With this basis, the researchers recommend the adaptation of this homemade bouncy polymer on the teaching-learning process which can be used by both teachers and students specifically in representing chemical reactions in Chemistry and demonstration of some laws in Physics. To further improve the project study, the researcher would also like to recommend the following: 1. Experiment with the ratio between the amounts of glue, cornstarch, and borax; 2.Experiment on the floor where the homemade bouncy polymer will bounce the highest, on a wood, on a glass or on a concrete floor; 3. Experiment if temperature will affect the characteristics of the homemade bouncy polymer; 4. Experiment if the size will affect the height of bounce/return, length of stretch and distance of roll; and, 30 5. Experiment if the homemade polymer can be used as an alternative on some rubber products. Moreover, other investigators are encouraged similar project to improve the quality and provide homemade bouncy polymer.
