| The hypothesis stated the type of water sealer would affect mass of wood blocks soaked in water. The data collected supports the hypothesis. | CONCLUSION |
| Starts with “Does” or “Will”, contains IV and DV, and ends with “?” | PROBLEM |
| -Written as numbered steps -Each step begins with a verb, “command” statements | PROCEDURE |
| -Restates hypothesis -States whether hypothesis is supported or not supported | CONCLUSION |
| 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 |
| Will ___________affect ______? | PROBLEM |
| If ___________ decreases, then ________ will decrease. | HYPOTHESIS |
| 1. Get 30 wood blocks 24 cm x 6 cm. 2. Apply 25 mL of carboxyl sealer to 10 of the wood blocks. 3. Allow to dry for 24 hours. 4. ….continued | PROCEDURE |
| -Contains numbers. -Usually refers to statistical analysis like average, mean, median, or range. | RESULTS |
| Occurrence that is noticed using senses but is not measured | OBSERVATION |
| may be qualitative or quantitative | OBSERVATION |
| The girl was crying. | QUALITATIVE OBSERVATION |
| The grass was wet in the morning so it must have rained. | INFERENCE |
| Conclusion based on logical reasoning | INFERENCE |
| The bird's babies were chirping because they were hungry | INFERENCE |
| The grass that was fertilized was a dark green | QUALITATIVE OBSERVATION |
| The grass was a darker green because it had been fertilized | INFERENCE |
