| 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 |
| 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 |
| type of water sealer | INDEPENDENT VARIABLE |
| mass of wood blocks after soaking in water | DEPENDENT VARIABLE |
| 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 |
| COMPONENT MANIPULATED BY EXPERIMENTER | INDEPENDENT VARIABLE |
| FOUND BEFORE VERB IN PROBLEM STATEMENT | INDEPENDENT VARIABLE |
| FOUND BEFORE "THEN" IN HYPOTHESIS | INDEPENDENT VARIABLE |
| PROBLEM: WILL THE TYPE OF SURFACE AFFECT THE DISTANCE A TOY CAR WILL TRAVEL? "TYPE OF SURFACE" | INDEPENDENT VARIABLE |
| COMPONENT THAT MAY CHANGE AS A RESULT OF THE INDEPENDENT VARIABLE | DEPENDENT VARIABLE |
| FOUND AFTER THE VERB IN A PROBLEM STATEMENT | DEPENDENT VARIABLE |
| FOUND AFTER "THEN" IN HYPOTHESIS | DEPENDENT VARIABLE |
| PROBLEM: WILL THE TYPE OF SURFACE AFFECT THE DISTANCE A TOY CAR WILL TRAVEL? "DISTANCE TOY CAR WILL TRAVEL" | DEPENDENT VARIABLE |
| THE "NORMAL" GROUP | CONTROL GROUP |
| TEST/EXPERIEMENTAL GROUP WITHOUT THE IV | CONTROL GROUP |
| THE DISTANCE TOY CAR WILL TRAVEL WITHOUT A SURFACE....NONE DEFINED, TRUE COMPARISON | CONTROL GROUP |
| REPEATNG THE EXPERIMENT MULTIPLE TIMES (AT LEAST 10) FOR EACH TEST/IV GROUP | RETESTS |
| TEN TRIALS FOR EACH TYPE OF SURFACE. | RETESTS |
| PARTS OF THE EXPERIMENT KEPT THE SAME SO THE ONLY REASON FOR A DIFFERENCE IN DATA IS THE IV | CONSTANTS |
| SHOULD NOT REFER TO THE IV OR DV | CONSTANTS |
| THE SAME LENGTH OF RAMP. THE SAME HEIGHT OF RAMP. THE SAME AERODYNAMICS OF TOY CAR. THE SAME TIRES. THE SAME METHOD FOR RELEASING THE CAR. | CONSTANTS |
| 23.67 mm = ______ cm | 2.37 cm |
| 1.98 g = ________ mg | 1980.00 mg |
| A 33.65 gram object is immersed in 20.00 ml of water. The water level raises to 29.50 mL of water. What is the objects density? | F: D = M/V W: M = 33.65 g / V = 29.50 ml - 20.00 ml = 9.50 m. A: D = 3.54 g/mL |
