In the Experimental Department, students are introduced to the process of design testing and evaluation, statistics and data analysis by gathering information about the flights of paper airplanes. Several test flights of a plane are completed and the data is analyzed by finding the range, mean and median of the data. Design changes may be implemented based on the data analysis. Information and values from other sets of data are also displayed in different graphical formats for interpretation.
This purpose of this outline is to help you navigate to specific parts of the lesson without having to go through every page. The section titles link to the first pages of that section, and the numbers in parentheses refer to the page number where that section starts.
At the end of this lesson, students will:
30-40 minutes depending on student's reading ability.
Standard 1: Mathematics as Problem Solving
- Use problem solving approaches to investigate and understand mathematical content.
- Verify and interpret given results and generalize solutions and strategies to a new problem.
- Gain confidence by using math meaningfully.
Standard 2: Mathematics as Communication
- Interpret and evaluate mathematical ideas presented in written and visual forms.
- Discuss mathematical ideas and make convincing arguments.

- Select and use an appropriate method for computing.
- Use computation to solve problems.
Standard 8: Patterns and Functions
- Analyze functional relationships to explain how a change in one quantity results in a change in another.
Standard 9: Algebra
- Represent situations and number patterns with tables, graphs, number lines, verbal rules and explore the interrelationships of these representations.
- Develop confidence in solving linear equations using concrete methods.
- Apply algebraic methods tools to solve real world and mathematical problems.
Standard 10: Statistics
- Collect, organize and describe data.
- Read and interpret tables and graphs.
- Make inferences and convincing arguments that are based on data analysis.
- Evaluate argruments that are based on data analysis.
- Develop an appreciation for statistical methods as powerful means for decision making.
Standard 13: Measurement
- Estimate, make and use measurements to describe and compare phenomena.
For helping with calculations:
For Straw Glider:
This lesson can be completed individually but will move faster and be more fun if two or more people work together. The lesson can be done in under half an hour if the students are good readers and have a calculator to assist with computations. Pair up students if someone is unable to hold or manipulate objects. Students who are unable to write can provide verbal input on project or make choices during activity.
1. Using the Straw Glider model provided, student can create and conduct their own test flights, gathering and analyzing the data. This can be done induvidually, or in groups. Based on their initial results, have students modify their Straw Gliders by changing the fuselage length, wingspan, or tail size. Then, re-test the glider and compare these results from the original results. What has changed? How might different modifications affect flight?
2. Repeat the above mentioned experiment with each student group creating and testing a different paper airplane. As a whole class, analyze the results from each of the different ariplanes and draw conclusions about patterns, differences and functions of the various parts of the planes.
3. Gather data from other sources (i.e. school sporting events, elections) and analyze them using mean, median and range. What conclusions can you draw from using this kind of data analysis?
4. Have students gather data on each other or on their family members. Be creative and try think of other categories in addition to age, height, weight, etc. What can you find out about your class by analyzing this data?
