Plan: PROBLEM: What is the most common month for birthdays at our school? RESEARCH: Survey your class and find out what is the most common month for
birthdays in your class. HYPOTHESIS: Do you think it will probably be the same for the whole school? MATERIALS: Tickets – to be distributed to all students at our school
Student population for the school
Data table – to be compiled during class by students who collected data
PROCEDURE: - Gather tickets from ten students at our school. Each student may volunteer
information only once.
- At the time you gather the tickets, record in your data the name of
the student and the month of birth of the student whose ticket you take.
DATA:
Your data must include: - The data you collect from ten students (See sample below)
- The data from your team
- Data from all the classes on the core team (See sample below)
- A graph that show the number of students whose birthdays are in each
month (See sample below)
CONCLUSION: This is not optional. You must explain what you learned by doing
this activity. Remember that you must answer the question you asked in your
original problem statement.
NOTE: BE SURE TO HAVE YOUR PARENT OR GUARDIAN SIGNS YOUR WORK.
PARENTS: YOUR SIGNATURE SHOWS YOUR STUDENT HAS DONE THE WORK Comments: POSSIBLE HYPOTHESIS: Students may feel that the sample size with just one
class is sufficient. However, for the data to be dependable, a larger sample
must be taken. POSSIBLE CONCLUSION: Students should compare the accuracy of their hypothesis
with the actual results. It will be interesting to see how accurate the original sample turns out. |
