SCIENTIFIC METHOD

The Penny Drop Lab

Introduction: Which side of a penny will hold more drops of water before spilling over on to a paper towel?

OBJECTIVE: In this activity, you will use the scientific method of inquiry to perform a laboratory experiment. The basic parts of the scientific process include the following:

1. Make observations 2. Formulate an hypothesis 3. Test the hypothesis 4. Collect and analyze data 5. Draw a conclusion

Materials: Small beaker of distilled water Paper towels one pipette One penny Alcohol 2 cotton balls Ruler

PROCEDURE: 1. As you follow the instructions to complete this lab, fill in the steps of the scientific method by writing what you did at each step.

STATE PROBLEM: ____________________________________________________________ ____________________________________________________________ ____________________________________________________________ ____________________________________________

RECORD SEVERAL OBSERVATIONS ABOUT THE PENNY: a. (Sample answers include : civilizations had a number system, a language, honored important people, knowledge about metallurgy and architecture, tools for mining, religion, etc.) b. c. d. e. f.

FORMULATE A HYPOTHESIS: ____________________________________________________________ ____________________________________________________________ ____________________________________________________________ ____________________________________________

TEST THE HYPOTHESIS ? PROCEDURE: 1. Using a paper towel, clean both sides of the penny with alcohol.

Why do you think you are doing this? 2. On the lab table, place the penny heads up on a paper towel. 3. Squeeze the bulb of the pipette so that one drop lands on the penny.

Record this number in the data table. 4. Wipe the penny dry of water. 5. Repeat steps 1-4 two more times. Record these numbers in the data

table. 6. Calculate the mean (average) of the three trials and enter in the data

table. 7. Flip the penny to the tails side and repeat steps 3-6.

ANALYZE DATA: HEADS ? TAILS ?

GRAPH DATA: Construct a bar graph using your data collected. Plot the MEAN data for both heads and tails on the same bar graph. Color the bar graph using one color for heads and a different color for tails. Remember to label all parts of your bar graph.
