Creating Model Working Lungs: Just Breathe Elementary School Activity
Students explore the inhalation/exhalation process that occurs in the lungs during respiration. Using everyday materials, each student team creates a model pair of lungs.
Paper Airplanes: Building, Testing, & Improving. Heads Up! Middle School Activity
Students learn the different airplane parts, including wing, flap, aileron, fuselage, cockpit, propeller, spinner, engine, tail, rudder, elevator. Then they each build one of four different (provided) paper airplane (really, glider) designs with instructions, which they test in three trials, measuring flight distance and time. Then they design and build (fold, cut) a second paper airplane design of their own creation, which they also test for flight distance and time. They graph the collected class data. Analysis of these experiments with "model" airplanes and their results help them see and figure out what makes airplanes fly and what can be changed to influence the flying characteristics and performance of airplanes.
Solving Everyday Problems Using the Engineering Design Cycle Middle School Activity
Students are introduced to two real-life problems that can be solved by using the engineering design process. For the first one, they follow along with a slide presentation that describes how a group of students built an organizer to help organize their teacher’s desk. The presentation introduces students to the key steps in the engineering design process. Next, in discussion groups, they read through a scenario in which middle school student Marisol struggles to keep her locker organized. They read the case study together, stopping and discussing at key points to share ideas and consider Marisol’s progress as she moves through the engineering design cycle to design and implement a solution. As an optional hands-on activity extension, students construct their own locker organizer using scrap materials. This introduction to the engineering design process sets up students to be able to conduct their own real-world design projects. A case study handout, group leader discussion sheet and slide presentation are provided.
The Dirty Water Project: Design-Build-Test Your Own Water Filters Elementary School Activity
In this hands-on activity, students investigate different methods—aeration and filtering—for removing pollutants from water. Working in teams, they design, build and test their own water filters—essentially conducting their own "dirty water projects." A guiding data collection worksheet is provided.
Magnetic Attraction Elementary School Activity
Students complete a series of six short investigations involving magnets to learn more about their properties. Students also discuss engineering uses for magnets and brainstorm examples of magnets in use in their everyday lives.
Engineers Speak for the Trees Elementary School Activity
Students begin by reading Dr. Seuss' "The Lorax" as an example of how overdevelopment can cause long-lasting environmental destruction. Students discuss how to balance the needs of the environment with the needs of human industry. Student teams are asked to serve as natural resource engineers, city planning engineers and civil engineers with the task to replant the nearly destroyed forest and develop a sustainable community design that can co-exist with the re-established natural area.
Properties of Mixtures vs. Solutions: Mix It Up! Elementary School Lesson
Students are introduced to the distinctive properties of mixtures and solutions. A class demonstration led by the teachers gives students the opportunity to compare and contrast the physical characteristics of a few simple mixtures and solutions. They discuss the separation of mixtures and solutions back into their original components as well as different engineering applications of mixtures and solutions.
Design a Parachute Middle School Activity
After a discussion about what a parachute is and how it works, students create parachutes using different materials that they think will work best. They test their designs, and then contribute to a class discussion (and possible journal writing) to report which paper materials worked best.
DNA: The Human Body Recipe Middle School Lesson
As a class, students work through an example showing how DNA provides the "recipe" for making human body proteins. They see how the pattern of nucleotide bases (adenine, thymine, guanine, cytosine) forms the double helix ladder shape of DNA, and serves as the code for the steps required to make genes. Students extend their knowledge by conducting the associated activities to learn ways that engineers and scientists are applying their understanding of DNA in our world.
Take Off with Paper Airplanes Middle School Lesson
Students are introduced to the art of designing airplanes through paper airplane constructions. The goal is for students to learn important aircraft design considerations and how engineers must iterate their designs to achieve success. They learn about the basic parts that can be found on most airplanes, and their functions. They also learn how engineers make small-scale models to test ideas and improve early designs. This prepares students for the associated activity in which they first make and test several provided paper airplane designs, after which they design and test their own paper airplane designs.
Element, Mixture, Compound High School Activity
Students gain a better understanding of the different types of materials as pure substances and mixtures and learn to distinguish between homogeneous and heterogeneous mixtures by discussing an assortment of example materials they use and encounter in their daily lives.
Vector Voyage! High School Activity
Students use vector analysis to understand the concept of dead reckoning. They use vectors to plot a course based on a time and speed. Then they correct the positions with vectors representing winds and currents.
Simple Machines Middle School Unit
Through a five-lesson series with five activities, students are introduced to six simple machines—inclined plane, wedge, screw, lever, pulley, wheel-and-axle—as well as compound machines, which are combinations of two or more simple machines. Once students understand about work (work = force x distance), they become familiar with the machines' mechanical advantages, and see how they make work easier. Through an introduction to compound machines, students begin to think critically about machine inventions and their pervasive roles in our lives. After learning about Rube Goldberg contraptions—absurd inventions that complete simple tasks in complicated ways—they evaluate the importance and usefulness of the many machines around them. Through the hands-on activities, students draw designs for contraptions that could move a circus elephant into a rail car, create a construction site ramp design by measuring different inclined planes and calculating the ideal vs. actual mechanical advantage of each, compare the theoretical and actual mechanical advantages of different pulley systems conceived to save a whale, build and test grape catapults made with popsicle sticks and rubber bands, and follow the steps of the engineering design process to design and build Rube Goldberg machines.
Up, Up and Away! - Airplanes Middle School Unit
The airplanes unit begins with a lesson on how airplanes create lift, which involves a discussion of air pressure and how wings use Bernoulli's principle to change air pressure. Next, students explore the other three forces acting on airplanes—thrust, weight and drag. Following these lessons, students learn how airplanes are controlled and use paper airplanes to demonstrate these principles. The final lessons addresses societal and technological impacts that airplanes have had on our world. Students learn about different kinds of airplanes and then design and build their own balsa wood airplanes based on what they have learned.
Invent a Backscratcher from Everyday Materials Elementary School Activity
Being able to recognize a problem and design a potential solution is the first step in the development of new and useful products. In this activity, students create devices to get "that pesky itch in the center of your back." Once the idea is thought through, students produce design schematics (sketches). They are given a variety of everyday materials and recyclables, from which they prototype their back-scratching devices.
