The Minerals We Eat: Iron-Fortified Breakfast Elementary School Lesson
Students learn that minerals are a necessary part of our diets and that different minerals have different functions in the body. More specifically, they discover that iron is necessary to carry oxygen throughout our bodies. In the associated activity, students design a process to reverse engineer an iron-fortified cereal to determine how much iron it contains by removing most of the iron from the cereal.
Physics of Roller Coasters Middle School Lesson
Students explore the physics exploited by engineers in designing today's roller coasters, including potential and kinetic energy, friction and gravity. First, they learn that all true roller coasters are completely driven by the force of gravity and that the conversion between potential and kinetic energy is essential to all roller coasters. Second, they consider the role of friction in slowing down cars in roller coasters. Finally, they examine the acceleration of roller coaster cars as they travel around the track. During the associated activity, students design, build and analyze model roller coasters they make using foam tubing and marbles (as the cars).
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.
What Is Newton's Third Law? Middle School Lesson
Students are introduced to Newton's third law of motion: For every action, there is an equal and opposite reaction. They practice identifying action-reaction force pairs for a variety of real-world examples, and draw and explain simplified free-body diagram vectors (arrows) of force, velocity and acceleration for them. They also learn that engineers apply Newton's third law and an understanding of reaction forces when designing a wide range of creations, from rockets and aircraft to door knobs, rifles and medicine delivery systems. This lesson is the third in a series of three lessons intended to be taught prior to a culminating associated activity to complete the unit.
Lunar Lollipops: Reproducing the Moon Phases Elementary School Activity
Students work in teams of two to discover the relative positions of the Earth, Sun and Moon that produce the different phases of the Moon. Groups are each given a Styrofoam ball that they attach to a pencil so that it looks like a lollipop. In this acting-out model exercise, this ball on a stick represents the Moon, the students represent the Earth and a hanging lightbulb serves as the Sun. Students move the "Moon" around them to discover the different phases. They fill in the position of the Moon and its corresponding phase in a worksheet.
Commanding a Robot Using Sound Middle School Activity
Students continue their exploration of the human senses and their engineering counterparts, focusing on the auditory sense. Working in small groups, students design, create and run programs to control the motion of LEGO® TaskBots. By doing this, they increase their understanding of the use and function of sound sensors, gain experience writing robot programs, and reinforce their understanding of the sensory process. **Note: This activity uses the retired LEGO NXT robot which is no longer available for purchase.
Renewable Energy Elementary School Lesson
In this lesson, students are introduced to the five types of renewable energy resources by engaging in various activities to help them understand the transformation of energy (solar, water and wind) into electricity. Students explore the different roles engineers who work in renewable energy fields have in creating a sustainable environment – an environment that contributes to greater health, happiness and safety.
What Is Energy? Elementary School Lesson
With an introduction to the ideas of energy, students discuss specific energy types and practical energy sources. Associated hands-on activities help them identify energy types in their surroundings and enhance their understanding of the concept of energy.
Red Cabbage Chemistry Middle School Activity
Students take advantage of the natural ability of red cabbage juice to perform as a pH indicator to test the pH of seven common household liquids. Then they evaluate the accuracy of the red cabbage indicator, by testing the pH of the liquids using an engineer-designed tool, pH indicator strips. Like environmental engineers working on water remediation or water treatment projects, understanding the chemical properties (including pH) of contaminants is important for safeguarding the health of environmental water sources and systems.
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.
Introduction to Genetic Engineering and Its Applications High School Lesson
Students learn how engineers apply their understanding of DNA to manipulate specific genes to produce desired traits, and how engineers have used this practice to address current problems facing humanity. They learn what genetic engineering means and examples of its applications, as well as moral and ethical problems related to its implementation. Students fill out a flow chart to list the methods to modify genes to create GMOs and example applications of bacteria, plant and animal GMOs.
All About Water! Elementary School Lesson
Students learn about the differences between surface and ground water as well as the differences between streams, rivers and lakes. Then, they learn about dissolved organic matter (DOM) and the role it plays in identifying drinking water sources. Then students are introduced to conventional drinking water treatment processes by developing and implementing their own water filtration system through the associated activity. A student worksheet and answer key are provided.
Bone Fractures and Engineering High School Lesson
Students learn about the role engineers and engineering play in repairing severe bone fractures. They acquire knowledge about the design and development of implant rods, pins, plates, screws and bone grafts. Students then can use the associated activity to practice their own bone repairing procedure. They learn about materials science, biocompatibility and minimally-invasive surgery.
Water Cycle Elementary School CurricularUnit
Water is essential to life. Understanding how the water cycle works, the importance of water as a natural resource, and how our household water cycle functions is essential knowledge for everyone. Through a range of water-based explorations and the engineering design process, students learn about the water cycle and how engineers manage it.
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.
