Engineering in the World of Dr. Seuss

(View Complete Item Description)

Students are introduced to the engineering design process within the context of reading Dr. Seuss’s book, Bartholomew and the Oobleck. To do so, students study a sample of aloe vera gel (representing the oobleck) in lab groups. After analyzing the substance, they use the engineering design process to develop and test other substances in order to make it easier for rain to wash away the oobleck. Students must work within a set of constraints outlined within the Seuss book and throughout the activity and use only substances available within the context of the plot. Students also take into consideration the financial and environmental costs associated with each substance.

Cool Puppy! A Doghouse Design Project

(View Complete Item Description)

Students are given the engineering challenge to design and build doghouses that shelter a (toy) puppy from the heat—and to create them within material, size and cost constraints. This requires them to apply what they know (or research) about light energy and how it does (or does not) travel through various materials, as well as how a material’s color affects its light absorption and reflection properties. They build their doghouse designs and test them by taking thermometer readings under hot lamps, and then think of ways to improve their designs. This is a great project for learning about light and heat: energy transfer, absorption, insulation and material properties, and easily scales up/down for size and materials.

Making Sense of Sensors: Visualizing Sensor Data

(View Complete Item Description)

The goal of this maker challenge is to demystify sensors, in particular the ambient light sensor, and to map its readings visually. In today’s world, we make sense of the environment around us by filling it with sensors, and we use output devices to display real-time data in a meaningful way. Take any smartphone as an example. Aside from the embedded camera and microphone, a number of other sensors collect a wide range of data. Depending upon the model, these sensors may collect data on proximity, motion, ambient light, moisture, compass, and touch. Some of these data are directly visualized through an app, while many operate internally and without a user interface, just below the surface of the screen. In order to become more familiar with the technology that we use (and often take for granted) on a daily basis, your challenge is to assemble a light sensor circuit, observe its readings using the Arduino Serial Monitor, and then create your own unique visualization by interfacing with the Processing software. Students learn how to use calibration and smoothing to capture a better picture of the data. Afterwards, they share their visualizations with the entire class. The time required for this challenge depends on students’ prior knowledge of Arduino and Processing software. Background resources for beginners help students get up to speed on microcontroller hardware and offer additional challenges for intermediate and advanced users.

Build Your Own Night-Light with Arduino

(View Complete Item Description)

Whether you want to light up a front step or a bathroom, it helps to have a light come on automatically when darkness falls. For this maker challenge, students create their own night-lights using Arduino microcontrollers, photocells and (supplied) code to sense light levels and turn on/off LEDs as they specify. As they build, test, and control these night-lights, they learn about voltage divider circuits and then experience the fundamental power of microcontrollers—controlling outputs (LEDs) based on sensor (photocell) input readings and if/then/else commands. Then they are challenged to personalize (and complicate) their night-lights—such as by using delays to change the LED blinking rate to reflect the amount of ambient light, or use many LEDs and several if/else statements with ranges to create a light meter. The possibilities are unlimited!

Create and Control a Popsicle Stick Finger Robot

(View Complete Item Description)

Students are introduced to servos and the flex sensor as they create simple, one-jointed, finger robots controlled by Arduino. Servos are motors with feedback and are extensively used in industrial and consumer applications—from large industrial car-manufacturing robots that use servos to hold heavy metal and precisely weld components together, to prosthetic hands that rely on servos to provide fine motor control. Students use Arduino microcontrollers and flex sensors to read finger flexes, which they process to send angle information to the servos. Students create working circuits; use the constrain, map and smoothing commands; learn what is meant by library and abstraction in a coding context; and may even combine team finger designs to create a complete prosthetic hand of bendable fingers.

Robo Clock

(View Complete Item Description)

Students learn various topics associated with the circle through studying a clock. Topics include reading analog time, understanding the concept of rotation (clockwise vs. counter-clockwise), and identifying right angles and straight angles within circles. Many young students have difficulty telling time in analog format, especially with fewer analog clocks in use (compared to digital clocks). This includes the ability to convert time written in words to a number format, for example, making the connection between "quarter of an hour" to 15 minutes. Students also find it difficult to convert "quarter of an hour" to the number of degrees in a circle. This activity incorporates a LEGO® MINDSTORMS® NXT robot to help students distinguish and visualize the differences in clockwise vs. counter-clockwise rotation and right vs. straight angles, while learning how to tell time on an analog clock. To promote team learning and increase engagement, students work in teams to program and control the robot.

Bone Density Math and Logarithm Introduction

(View Complete Item Description)

In their reading from activity 1 of this unit, students should have discovered the term "logarithm." It is at this point that they begin their study of logarithms. Specifically, students examine the definition, history and relationship to exponents; they rewrite exponents as logarithms and vice versa, evaluating expressions, solving for a missing piece. Students then study the properties of logarithms (multiplication/addition, division/subtraction, exponents). They complete a set of practice problems to apply the skills they have learned (rewriting logarithms and exponents, evaluating expressions, solving/examining equations for a missing variable.) Then they complete a short quiz covering what they have studied thus far concerning logarithms (problems similar to the practice problems). They consider how what they have learned moves them closer to answering the unit's challenge question.

Master Driver

(View Complete Item Description)

As part of a design challenge, students learn how to use a rotation sensor (located inside the casing of a LEGO® MINDSTORMS ® NXT motor) to measure how far a robot moves with each rotation. Through experimentation and measurement with the sensor, student pairs determine the relationship between the number of rotations of the robot's wheels and the distance traveled by the robot. Then they use this ratio to program LEGO robots to move precise distances in a contest of accuracy. The robot that gets closest to the goal without touching the toy figures at the finish line is the winning programming design. Students learn how rotational sensors measure distance, how mathematics can be used for real-world purposes, and about potential sources of error due to gearing when using rotation sensor readings for distance calculations. They also become familiar with the engineering design process as they engage in its steps, from understanding the problem to multiple test/improve iterations to successful design.

Robinson Crusoe

(View Complete Item Description)

The Life and Strange Surprizing Adventures of Robinson Crusoe is one of those books that we all know even if we have never read it. With his first work of fiction, Daniel Defoe–a businessman turned poet, journalist, and political propagandist–created a character who very quickly went on to have a life that went well beyond the pages of the book that first appeared, without build-up, fanfare, or even the author’s name on the title page, in April 1719. Robinson Crusoe was an immediate bestseller; the bookseller went through several editions in the first year alone. By August, Defoe had produced a sequel, The Farther Adventures of Robinson Crusoe, a work that he wrote quickly in part to head off the possibility that someone else might beat him to it. Over the last three hundred years, the story of a person isolated on a deserted island or something like it, has been used by dozens, maybe hundreds of writers, who have made it a genre of its own, the “Robinsoniad,” a genre that includes satirical parodies like Gulliver’s Travels, children’s books like The Swiss Family Robinson, Bugs Bunny cartoons, television situation comedies like Gilligan’s Island, and science fiction works like The Martian. Robinson Crusoe, the man and the book in which he first appeared, has become one of the foundational myths of the modern world.The story of one man’s survival has become so well known in all of these instances that it can be difficult to see through the mythology to analyze Defoe’s original book and to imagine what its first readers might have noticed and found so striking. It is important to recognize, for example, that the book is told in the first person, by a narrator who never lets on that this is a work of fiction. Defoe’s name, as noted above, did not appear on the title page of the first edition (although it quickly became clear to those in the know that he was the author), or even in any of the many editions issued in his lifetime. Although the book is famous for the many years that Crusoe spends on the island, it takes a while for him to get there, and his experiences both before and after his time there are worth paying attention to for the way that they frame the central experience. Defoe’s prose is sometimes clunky-he has a tendency to shape sentences and paragraphs that would never pass muster with a modern copyeditor–but it is also capable of great beauty and insight, and rewards careful attention.

The Lunch-Bot

(View Complete Item Description)

Students are challenged to design and program Arduino-controlled robots that behave like simple versions of the automated guided vehicles engineers design for real-world applications. Using Arduino microcontroller boards, infrared (IR) sensors, servomotors, attachable wheels and plastic containers (for the robot frame), they make "Lunch-Bots." Teams program the robots to meet the project constraints—to follow a line of reflective tape, make turns and stop at a designated spot to deliver a package, such as a sandwich or pizza slice. They read and interpret analog voltages from IR sensors, compare how infrared reflects differently off different materials, and write Arduino programs that use IR sensor inputs to control the servomotors. Through the process, students experience the entire engineering design process. Pre/post-quizzes and coding help documents are provided.

E.T. Phone Home: Fact or Fiction?

(View Complete Item Description)

A favorite movie, “E.T. the Extra-Terrestrial,” provides the backdrop scenario for students to discover how harnessing the sun’s energy provides unlimited power for many purposes, including the operation of thousands of satellites in orbit today and communication over long distances. In the movie, E.T., an alien life form, is stranded on Earth and befriends Elliott, the little boy who rescues him. As E.T. becomes gravely ill, Elliott realizes that E.T. needs to return home in order to survive. To arrange for transport, E.T. must “phone home.” Teams engage in an interactive quest to answer the question: E.T. phone home—fact or fiction? They must discover four clues in order to unlock four padlocks on a box that contains the answer. This requires them to watch a one-minute online video, complete a crossword puzzle, scan three QR codes for articles to read, and put together a cut-apart puzzle with an invisible ink clue. They watch short online movie excerpt videos to kick off and wrap up the activity.

What Do I Need to Know about Heart Valves?

(View Complete Item Description)

Students are presented with the unit's grand challenge problem: You are the lead engineer for a biomaterials company that has a cardiovascular systems client who wants you to develop a model that can be used to test the properties of heart valves without using real specimens. How might you go about accomplishing this task? What information do you need to create an accurate model? How could your materials be tested? Students brainstorm as a class, then learn some basic information relevant to the problem (by reading the transcript of an interview with a biomedical engineer), and then learn more specific information on how heart tissues work their structure and composition (lecture information presented by the teacher). This prepares them for the associated activity, during which students cement their understanding of the heart and its function by dissecting sheep hearts to explore heart anatomy.

Bone Transplants—No Donors Necessary!

(View Complete Item Description)

Students investigate the bone structure of a turkey femur and then create their own prototype versions as if they are biomedical engineers designing bone transplants for a bird. The challenge is to mimic the size, shape, structure, mass and density of the real bone. Students begin by watching a TED Talk about printing a human kidney and reading a news article about 3D printing a replacement bone for an eagle. Then teams gather data—using calipers to get the exact turkey femur measurements—and determine the bone’s mass and density. They make to-scale sketches of the bone and then use modeling clay, plastic drinking straws and pipe cleaners to create 3D prototypes of the bone. Next, groups each cut and measure a turkey femur cross-section, which they draw in CAD software and then print on a 3D printer. Students reflect on the design/build process and the challenges encountered when making realistic bone replacements. A pre/post-quiz, worksheet and rubric are included. If no 3D printer, shorten the activity by just making the hand-generated replicate bones.

Combustion and Air Quality: Emissions Monitoring

(View Complete Item Description)

As a class, students use a low-cost air quality monitor (a rentable “Pod”) to measure the emissions from different vehicles. By applying the knowledge about combustion chemistry that they gain during the pre-activity reading (or lecture presentation, alternatively), students predict how the emissions from various vehicles will differ in terms of pollutants (CO2, VOCs and NO2), and explain why. After data collection, students examine the time series plots as a class—a chance to interpret the results and compare them to their predictions. Short online videos and a current event article help to highlight the real-world necessity of understanding and improving vehicle emissions. Numerous student handouts are provided. The activity content may be presented independently of its unit and without using an air quality monitor by analyzing provided sample data.
