## Unleash the Engineer in You: Tackle Everyday Problems with STEM Projects

- Crash! Can Cell Phones Survive a Drop Test? : make your own cases for calculators (or some other household item or toy) and experiment with "drop tests" to learn more about how products are tested and improved by product engineers.
- Stretchy Rubber Band Science : have you ever grabbed a rubber band and found it so brittle that it snapped when you tried to use it? If you are using rubber bands for a homemade (or wooden) rubber band launcher, or for a rubber band-based game, understanding how temperature affects rubber bands (and why) can be really important. Should you keep a rubber band stash out of the summer heat, or is summer heat exactly what you need for maximum stretch in your rubber bands? Find out with an interesting physics exploration!
- Moving Water with the Archimedes Screw Pump : can you easily move water from one place to another using a homemade device that you simply twist ? Experiment with a classic design by building your own Archimedes screw pump from ordinary materials. Can you improve the pump design to make it more efficient?
- Get Crafty — Create Your Own Durable Paper Doll : experiment with paper dolls to find ways to make them less likely to tear or break during play. Kids are tough on their toys! Can you come up with new approaches to the design or assembly that improve durability without changing the play value?
- Build a Gumdrop Geodesic Dome : build a geodesic dome from simple candies and toothpicks to see how math and physics combine in this structure. How strong is a geodesic dome? What variables influence its strength? What happens when you increase the scale of a geodesic dome and make it larger? What other materials can you try, and how can you put this structure's strength and durability to the test?
- Bridge Building Bonanza: Which Design Wins? : experiment with different kinds of bridge structures to explore questions related to materials, design, and stability.
- Keeping It Private: Blocking RFID Readers from Reading your ID Card : learn more about RFID technology and how RFID readers can be used to access information without someone realizing it. In this project, experiment to find out which materials can be used to help protect RFID information, data stored on an ID card, for example, and design your own protective case or barrier. Your project might change how you think about the information you (or your family members) carry in a pocket or bag!
- Applying Hooke's Law: Make Your Own Spring Scale : Make Your Own Spring Scale: make your own spring scale to learn more about this physics principle, and then put it to use around the house to try it out! You will need assorted household materials to build your scale, including a couple of different springs to try. You might even find what you need in the closet or toy box.

(two 60-minutes class periods)

Additional materials are required if the optional design/build activity extension is conducted.

Subject Areas: Science and Technology

NGSS Performance Expectations:

## TE Newsletter

After this activity, students should be able to:

- Explain the stages/steps of the engineering design process .
- Identify the engineering design process steps in a case study of a design/build example solution.
- Determine whether a design solution meets the project criteria and constraints.
- Think of daily life situations/problems that could be improved.

## Educational Standards Each TeachEngineering lesson or activity is correlated to one or more K-12 science, technology, engineering or math (STEM) educational standards. All 100,000+ K-12 STEM standards covered in TeachEngineering are collected, maintained and packaged by the Achievement Standards Network (ASN) , a project of D2L (www.achievementstandards.org). In the ASN, standards are hierarchically structured: first by source; e.g. , by state; within source by type; e.g. , science or mathematics; within type by subtype, then by grade, etc .

Do you agree with this alignment? Thanks for your feedback!

## State Standards

To share with the entire class:

- computer/projector setup to show the class the Introduction to the Engineering Design Cycle Presentation , a Microsoft® PowerPoint® file
- paper and pencils
- (optional) an assortment of scrap materials such as fabric, super glue, wood, paper, plastic, etc., provided by the teacher and/or contributed by students, to conduct the hands-on design/build extension activity

Ask: identify the need & constraints

- Identify and define the problem. Who does the problem affect? What needs to be accomplished? What is the overall goal of the project?
- Identify the criteria and constraints. The criteria are the requirements the solution must meet, such as designing a bag to hold at least 10 lbs. Constraints are the limitations and restrictions on a solution, such as a maximum budget or specific dimensions.

- Learn everything you can about the problem. Talk to experts and/or research what products or solutions already exist.
- If working for a client, such as designing new filters for a drinking water treatment plant, talk with the client to determine the needs and wants.

Imagine: develop possible solutions

Plan: select a promising solution

- Consider the pros and cons of all possible solutions, keeping in mind the criteria and constraints.
- Choose one solution and make a plan to move forward with it.

- Optimize the solution. Redesign parts that didn’t work, and test again.
- Iterate! Engineers improve their ideas and designs many times as they work towards a solution.

- Make copies of the five-page Marisol Case Study , one per student, and the Group Leader Discussion Sheet , one per group.
- Be ready to show the class the Introduction to the Engineering Design Cycle Presentation , a PowerPoint® file.

- As a pre-activity assessment, spend a few minutes asking students the questions provided in the Assessment section.
- Present the Introduction/Motivation content to the class, which includes using the slide presentation to introduce students to the engineering design cycle. Throughout, ask for their feedback, for example, any criteria or constraints that they would add, other design ideas or modifications, and so forth.
- Divide the class into groups of four. Ask each team to elect a group leader. Hand out the case study packets to each student. Provide each group leader with a discussion sheet.
- In their groups, have students work through the case study together.
- Alert students to the case study layout with its clearly labeled “stop” points, and direct them to just read section by section, not reading beyond those points.
- Suggest that students either taking turns reading each section aloud or read each section silently.
- Once all students in a group have read a section, the group leader refers to the discussion sheet and asks its questions of the group, facilitating a discussion that involves every student.
- Encourage students to annotate the case study as they like; for example, they might note in the margins Marisol’s stage in the design process at various points.
- As students work in their groups, walk around the classroom and encourage group discussion. Ensure that each group member contributes to the discussion and that group members are focused on the same section (no reading ahead).
- After all teams have finished the case study and its discussion questions, facilitate a class discussion about how Marisol used the engineering design cycle. This might include referring back to questions 4 and 5 in “Stop 5” to discuss remaining questions about the case study and relate the case study example back to the community problems students suggested in the pre-activity assessment.
- Administer the post-activity assessment.

develop : In the engineering design cycle, to create different solutions to an engineering problem.

optimize: To make the solution better after testing. Part of the engineering design cycle.

- What do engineers do? (Example possible answers: Engineers design things that help people, they design/build/create new things, they work on computers, they solve problems, they create things that have never existed before, etc.)
- What are some problems in your home, school or community that could be solved through engineering? (Example possible answers: It is too dark in a community field/park at night, it is hard to carry shopping bags in grocery store carts, the dishwasher does not clean the dishes well, we spend too much time trying to find shoes—or other items—in the house/garage/classroom, etc.)
- How do engineers solve problems? (Example possible answers: They build new things, design new things, etc. If not mentioned, introduce students to the idea of the engineering design cycle. Liken this to how research scientists are guided by the steps of the scientific method.)

- Which part of the engineering design cycle is Marisol working on as they design an organizer?
- Why is it important to identify the criteria and constraints of a project before building and testing a prototype? (Example possible answers: So that the prototype will be the right size, so that you do not go over budget, so that it will solve the problem, etc.)
- Why do engineers improve and optimize their designs? (Example possible answers: To make it work better, to fix unexpected problems that come up during testing, etc.)

- Before the activity: Inform students that they will be undertaking an engineering design challenge. Without handing out the case study packet, introduce students to Marisol’s problem: a disorganized locker. Ask students to bring materials from home that they think could help solve this problem. Then, gather assorted materials (wood and fabric scraps, craft materials, tape, glue, etc.) to provide for this challenge, giving each material a cost (for example, wood pieces cost 50¢, fabric costs 25¢, etc.) and write these on the board or on paper to hand out to the class.
- Present the Introduction/Motivation content and slides to introduce students to the engineering design process (as described above). Then have students go through the steps of the engineering design process to create a locker organizer for Marisol. Inform them Marisol has only $3 to spend on an organizer, so they must work within this budget constraint. As a size constraint, tell students the locker is 32 inches tall, 12 inches wide and 9.5 inches deep. (Alternatively, have students measure their own lockers and determine the size themselves.)
- As students work, ask them some reflection questions such as, “Which step of the engineering design process are you working on?” and “Why have you chosen that solution?”
- Let groups present their organizers to the class and explain the logic behind their designs.
- Next, distribute the case study packet and discussion sheets to the student groups. As the teams read through the packet, encourage them to discuss the differences between their design solutions and Marisol’s. Mention that in engineering design there is no one right answer; rather, many possible solutions may exist. Multiple designs may be successful in imagining and fabricating a solution that meets the project criteria and constraints.

## Engineering Problem Solving ¶

Some problems are so complex that you have to be highly intelligent and well-informed just to be undecided about them. —Laurence J. Peter

## Steps in solving ‘real world’ engineering problems ¶

The following are the steps as enumerated in your textbook:

Evaluate and rank the possible solutions

Develop a detailed plan for the most attractive solution(s)

Re-evaluate the plan to check desirability

In a practical sense, these checks must be part of a comprehensive risk management strategy.

Step 3 above refers to ranking of alternatives.

Think of an existing product of interest.

What do you think was ranked highest when the product was developed?

Brainstorm ideas with the students around you.

This is difficult to assess without some experience in the particular environment.

How ‘Good’ a Solution Do You Need?

10 second answer (answering a question at a meeting in front of your manager or vice president)

10 minute answer (answering a quick question from a colleague)

10 hour answer (answering a request from an important customer)

10 day answer (putting together information as part of a trouble-shooting team)

## Steps in solving well-defined engineering process problems ¶

Draw a diagram if one is not already available.

Construct the material balance equation(s):

Start with the general equation (so you don’t forget something)

Discard terms that equal zero in your specific problem

A glaring omission in this procedure is a check of the answer.

How do you know your answer is right and that your analysis is correct?

## Engineer Dee's Blog

How to solve any problem in engineering in three basic steps.

But how does one approach a problem correctly? Just follow these three basic steps:

Moreover, do not forget the so-called boundary conditions, or constraints that apply to the problem.

- What principles or formulas are to be applied in this problem?
- What could be the underlying assumptions or conditions?
- Is there only one way to interpret the problem or one way to solve it?
- Can the sketch be simplified further?

But before submission, double check each step of the solution. Always.

## The Four Types of Problems Engineers Must Solve

## The Four Types of Problems Engineers Must Solve is a guest blog by Kyle K. Cheerangie, P.E.

In your engineering work, problems will arise under four basic categories, namely:.

- General problems that have already been solved by someone in your company (i.e. calculations that can be solved using already developed spreadsheets).
- General problems that have not been solved by someone in your company, but there are known ways for solving them throughout the industry (i.e. time-sheet management software that integrates project budgets).
- Problems that seem unique at first, but upon further investigation, fall under categories one or two.
- Specific problems that neither your company nor the industry has solved.

## Categorize Your Problems to Increase Your Effectiveness in Solving Them

## Category 1 Problems

## Category 2 Problems

## Category 3 Problems

## Category 4 Problems
