Thank you !!!

The general steps of the scientific method can be identified as this:

observation question hypothesis prediction experiment analysis conclusion

Read the following scenario: A librarian, Mrs. Smith, noticed that there seemed to be a lot more patrons in the library on rainy Saturdays than there were on sunny Saturdays.

1. What step of the scientific method does the above scenario represent?

2. What two variables does Mrs. Smith think are related?

            a.________________________

            b._________________________

3. Of the above two variables which is the independent variable and which is the dependent variable? Remember that you can think of them as one being a “cause” and the other an “effect”.

            Independent variable (“cause”) ________________________________________

            Dependent variable (“effect”) _________________________________________

4. State a broad, general hypothesis from Mrs. Smith’s observations.

5. Below is a table of data Mrs. Smith gathered over the course of 3 months.

Saturday weather

Total Number of Library patrons

6/6   Sunny

8

6/13 Sunny

6

6/20 Cloudy

9

6/27 Rainy

15

7/4 Library closed

0

7/11 Rainy

14

7/18 Cloudy

10

7/25 Rainy

19

8/1 Sunny

7

8/8 Sunny

8

8/15 Rainy

21

8/22 Cloudy

10

8/29 Rainy

18

6. Does this data appear to support Mrs. Smith’s hypothesis or not?

7. What is a specific conclusion that Mrs. Smith might make from this data?

Saturday weather	Total Number of Library patrons
6/6   Sunny	8
6/13 Sunny	6
6/20 Cloudy	9
6/27 Rainy	15
7/4 Library closed	0
7/11 Rainy	14
7/18 Cloudy	10
7/25 Rainy	19
8/1 Sunny	7
8/8 Sunny	8
8/15 Rainy	21
8/22 Cloudy	10
8/29 Rainy	18

Solution

1.The step of the scientific method that the above scenario represent is an observation.

2.The two variables that Mrs.Smith think are related are :

a.Number of patrons and

b.Weather on Saturday i.e rainy or sunny

3.Independent variable is :Saturday weather

Dependent variable is: Number of patrons.

4.Hypothesis : If it is a rainy Saturday ,then the number of patrons in the library will be more.

5 and 6. Yes, the data appears to support Mrs,Smith\'s hypothesis as from the table above it can be calculated and found out that the number of library patrons on rainy saturdays are more than sunny saturdays.

7.Specific conclusion:The hypothesis that if it is a rainy Saturday,then the number of patrons in the library will be more stands true.
