Science and Tech Trek Activity 8a:
Marketplace Math (Part One)

Activity Objective: Girls learn basic survey skills.

Toward Leadership Outcomes:

Through this activity, girls will:

  • Gain practical life skills—Girls have increased confidence in their ability to succeed in math and science. (Discover)

Experience Overview:

  • 2 min. Introduction (Talking Points)
  • 40 min. Marketplace Math
  • 10 min. Reflection/Discussion

Supplies Needed:

  • Paper (or journals) and pens or pencils (enough for each girl)
  • Large pad and marker (or chalkboard)
  • Pizza (enough for each girl)

*NOTE: Save the pizza box or boxes for use in the “Some Like It Hot” Science
and Tech Trek Activity 9.

Prepare Ahead:

  • Order and pick up pizzas.
  • Read over the entire activity before meeting with girls.

Step-by-Step Instructions:

» Introduction (Talking Points) (2 minutes)

  • Say something like this: “A market survey asks people what products they use or would be willing to try. It may also ask how much they would be willing to pay. The answers help businesspeople decide what products or services to offer. Today we will learn the basics of designing a survey. The basic skills of survey design can also be used to help us determine things we need to know when starting our own nonprofit business. In other words, a survey can also be used to determine peoples’ attitudes and needs, such as community improvements or services that are needed. But for today’s activity, just for fun, we will use pizza as a theme.”

  • Distribute paper and pens or pencils.
  • Explain that today girls will design the survey, determine a date for conducting the survey, and then tally the results.
  • As a group, go through the following steps (writing the answers on a large pad):
    • Determine what your survey question or questions will be. What do you want to find out? (For example, what is your favorite pizza topping?)
    • Decide who you will survey, and why. Adults? Kids?
    • Determine how many people you will need to survey in order to get a “good sample.” (Why this many people and not more or fewer people?)
    • Collect your data. (Where will you go?)
  • Make sure girls have written the exact survey question or questions, and have them come up with an action plan for conducting the survey. (How many people will each girl agree to talk to? How will they record their answers? When will they complete the survey? By the next meeting?)

» Reflection/Discussion (10 minutes)

Ask girls:

  • “Do you think it is important to do this kind of survey before starting your own business? Why or why not?”
  • “What other kind of research should you do before starting a business?”
    (For example, check out the competition.)
