•Summarize the engineering design process and scientific method.
•Provide examples of actions an engineer performs during each step of the
engineering design process.
•Design and create a package to protect a small, fragile food during shipping.
•Practice each step of the engineering design process while creating a
shipping package for a small, fragile food.
•Write a project description.

5. Warm-Up Activity (15 Minutes)
Materials Needed:
•Paper (1 sheet per group)
•Scissors (1 per group)
•Rulers (1 per group)
•Masking tape (10 cm per group)
•Books (any type) (at least 30 per class)
•Timers (1 per group)

6. Warm-Up Activity (15 Minutes)
•You are going to work with a partner to build a support system
that holds as many books as possible, exactly 2 cm off the table
top.
•Only materials are 10 cm of tape and 1 sheet of paper.
•Name characteristics of supports. Some examples are strong,
stable, and upright.
•The supports must hold the books exactly 2 cm off the tabletop
for at least 30 seconds.

7. Honor Code, Technology Use Policy,
Laboratory Safety Guidelines, and Contracts
(15 Minutes)

8. Pre-Assessment(30 Minutes)

9. Engineering Notebook Introduction (15 Minutes)
•Scientists and engineers keep journals or notebooks to plan, record observations, and reflect on
experiments and designs.
•Why an engineering notebook is important?
•The Engineering Notebook handouts.
•Use your notebooks to take notes during lectures.
•You are expected to include page headings, such as the date, the activity title, and the phase in
the engineering design process or scientific method
•When answering a reflection, analysis, or conclusion question, you are expected to write the
question and then record the answer underneath.

10. Engineering Notebook Introduction (15 Minutes)
•Write the date, Day 1, and Engineering Notebook Purpose
•Write these two questions:
What is the purpose of keeping an Engineering Notebook?
What should be included in a page header?
•Your Engineering Notebook will be collected and evaluated by the end of
summer training!

11. Getting to Know You! (15 Minutes)

12. Engineering versus Science Introduction
(15 Minutes)
•The focus of engineering is solving problems with known
information.
•The focus of science is investigating and analyzing data, then
developing rules and processes from that data.
Exercise
•List objects in the room. What problems are solved by the object?
What scientific principles might be the basis of the solution?

13. Engineering and Science Areas

14. Engineering Design Process, Scientific
Method, and Teamwork (15 Minutes)

15. Engineering Design Process, Scientific
Method, and Teamwork (15 Minutes)

16. Food Mailer Introduction and Brainstorming
(30 Minutes)
•Materials Needed:
•Food Mailer Project handouts (1 per student)
•Pens or pencils (student provided)
•Engineering Notebooks (student provided)
1) You are going to design and build a package to protect a small, fragile food during shipping.
2) Food Mailer handouts.
3) Review the allowable materials. These are the only allowable materials.
4) You are going to perform every step in the engineering design process as you make your Food Mailer
projects.
5) Brainstorm at least one way they could complete every step in the engineering design process during the
Food Mailer project.

17. Food Mailer Introduction and Brainstorming
(30 Minutes)
6) 10 minutes to record your ideas in your Engineering Notebooks.
7) Discuss ideas for each step in the design process.
8) Link their ideas to the actions students are performing during the project.
9) Review the project’s steps and timeline with students: Researching and Planning
Packages (30 minutes), Building Packages (30 minutes), Testing Packages (30
minutes), and Reflecting on Design (30 minutes).

18. Food Mailer Project Research and Planning
(30 Minutes)
Materials Needed:
•Small, fragile food (5 pieces per pair of students)
•Rulers (1 per pair of students)
•Scale
•Pens or pencils (student provided)
•Engineering Notebooks (student provided)
1) The first four steps in the engineering design process (Identify the Problem, Criteria, and
Constraints; Research Existing Solutions; Brainstorm Possible Solutions; and Select an Approach).
2) You are going to do a quick version of each step since this is a basic project.
3) First discuss the Food Mailer problem, criteria, and constraints with your partner. Limited time,
materials, and team size are all design constraints or limits for this project.
4) Looking up package designs online, or remembering packages have seen.
5) Select a design approach and begin planning your Food Mailer project design.

19. Food Mailer Project Building (30 Minutes)
Materials Needed:
•Small, fragile food (5 pieces per pair of students)
•Cardboard boxes (1 per pair of students)
•Packing tape (up to 50 cm per pair of students)
•Masking tape (up to 50 cm per pair of students)
•Glue (up to 1 bottle per pair of students)
•Bubble wrap (up to 12.5 cm square or 156 cm2 area per pair of students)
•Rubber bands (up to 5 per pair of students)
•Toothpicks (up to 20 per pair of students)
•Rulers (1 per pair of students)
•Scissors (1 per pair of students)
•Utility knives, retractable (1 per pair of students)

20. Food Mailer Project Building (30 Minutes)
1)Build their Food Mailer projects. (30 minutes)
2) Reminder: the goal is to build a package that prevents a small, fragile
food from breaking when sent through the mail.
3) Modify your design plans while building. They may only use the
allotted materials.

21. Food Mailer Project Testing (30 Minutes)
Materials Needed:
•Built Food Mailer packages (1 per pair of students)
•Small, fragile food (1 piece per pair of students)
•Tools and materials students request for testing
•Pens or pencils (student provided)
•Engineering Notebooks (student provided)
1) Design and perform three tests to simulate what the food and package might
experience during your time in the mail. Write your procedures and results in their
Engineering Notebooks.
2) Modify your designs based on the test results.

22. Food Mailer Project Reflection (30 Minutes)
Materials Needed:
•Chalkboard and chalk or whiteboard and markers
•Pens or pencils (student provided)
•Laboratory Notebooks (student provided)
1) Pass the best performing Food Mailer projects around the room.
2) Describe the projects in your Engineering Notebooks.
3) Discuss the common design features.
4) What science concepts might be linked to those package designs that performed the best.
5) What science concepts that caused the packages’ high performance. Structural and
material properties are likely causes of high package success.
6) Summarize project

23. Wrap Up (15 Minutes)
1) A review of the day’s important points.
2) Any questions about the day’s lessons.
3) A preview of the next class.
