PVA GLUE REPORT
SCIENCE ASSIGNMENT
PURPOSE
The purpose of this investigation is to test the strength of three commercial PVA glues to find the strongest and the most financially viable option.
HYPOTHESIS
The bond between wood to wood will have a better bond strength than the wood/plastic.
MATERIALS:
1. GLUE 2. WOOD 3. PLASTIC 4. WEIGHTS (500G,1KG,2KG) 5. RETORT STAND 6. BUCKET 7. CHAIR (FOR SAFETY REASONS) 8. PADDLEPOPSTICKS 9. CLAMP
METHOD:
1. Drill a hole in three of the paddle pops and all of the rulers. 2. Glue holed paddle pops to paddle pops and rulers to paddle pops. 3. Allow to cure for at least 24 hours. 4. Set up a retort stand on side of bench and clamp it there. 5. Fasten the paddle pop into the stand, making sure the hole is at the bottom. 6. Suspend weights from the hole in the paddle pop. 7. Measure the breaking point of the bond. 8. Record all the results and repeat the process for all other tests.
RESULTS:
TOTAL | GLUE A | GLUE B | GLUE C | AVERAGE | 2195 g | 955.6g | 2505.5g | AVERAGE WITHOUT ANOMALIES | 1656.25g | 657.2g | 1935.7g |

*MEANS THAT THE RESULT IS AN ANOMALIE. HOW DOES THIS ANOMALIE CHANGE THE DATA (refer to this graph ^^^)
ANALYSIS:
ITEM: 1 –
The purpose of this experiment was to test the strength of the bond between three types of glue on two different surfaces.
ITEM: 2-
The amount of glue was kept the same by keeping it to one drop. The measurement between/overlapping of the paddle pop sticks we kept were the same measurement at 2cm and 1cm for the drop of glue. The duration of the experiment conducted was the same. It was done in the
