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 |
the part of the experiment, that the person doing the experiment changes or controls | INDEPENDENT VARIABLE |
part of the experiment being measured | DEPENDENT VARIABLE |
mass of food chickens eat | DEPENDENT VARIABLE |
amount of sunlight | INDEPENDENT VARIABLE |
the non-experimental group | CONTROL GROUP |
keeps all necessary parts of the experimental design the same so the only effect caused by IV | CONSTANTS |
repetition of the experiment; should have a minimum of 10 for each group | RETESTS/TRIALS |
there were 3 worms on the ground | QUANTITATIVE OBSERVATION |
type of water sealer | INDEPENDENT VARIABLE |
mass of wood blocks after soaking in water | DEPENDENT VARIABLE |
the corn was a meter taller than the beans | QUANTITATIVE OBSERATION |
The same amount of time the wood blocks are soaked in water. | CONSTANT |
The wood blocks not treated with sealer. | CONTROL GROUP |
Thirty trials for each type of wood sealer and the control group. | RETESTS |
