OF THE SCIENTIFIC METHOD
TEACHING EXAMPLES
THE PAPER TOWEL WITH GREAT HOLDING
POWER
1. Statement of Purpose or Question: Which paper towel will hold the most
water?
2. 2. HypothesisHypothesis::When Brawny, Scott and a store brand are tested for When Brawny, Scott and a store brand are tested for absorbency, then … will be proven to hold the most absorbency, then … will be proven to hold the most
water.water.
3. Variables:
Brand of paper towel
B. Dependent Variable
Brand of paper towel
C. Constants or Controls
Amounts of water added to paper towelSize of the paper towelProcess of determining amount of water left Time water is on paper towelTest all three brands around the same time and on the same day
A. Independent Variable
4. Standards of Comparison:
5. Materials and Procedure :
Color and size of each brand of paper towel
A. Materials
roll of Brawny, Scott & store brand waterGraduated cylinder scissorscalculator panextra paper towels ruler
B. Procedures:1. Get all materials.2. Review my directions for experiment.3. Cut paper towels into 4 cm x 4 cm squares.4. Lay one square of Bounty paper towel in the e pan.5. Measure out 10 ml of water and add to paper towel in
pan.6. Let it set for one for one minute.7. Pick up paper towel with forceps and let the extra
water drip out of paper towel until the drops are at least five seconds apart.
8. Pour water in cake pan back into the graduated cylinder and calculate the amount of water the square of paper to held.
9. Repeat steps 5-9 for each paper towel for total of fifty times.
6. QUALITATIVE OBSERVATIONS:
7. Quantitative Results:A. Raw Data
