| Will the type of water sealer affect mass of wood blocks soaked in water in grams? | PROBLEM |
| If the type of sealer changes, then the amount of mass wood blocks will change. The blocks that have the sealer that contains carboxyl will gain the least amount of water. | HYPOTHESIS |
| The wood blocks with carboxyl applied gained an average of 26.32 grams. The wood bricks with acetyl acetate applied gained an average of 33.77 grams. | RESULTS |
