Lesson explore sensors focusing on ones that measure humidity. Young scholars work in teams to design, build, test, and evaluate a hygrometer which was made out of everyday materials to measure humidity levels.

Students investigate the materials properties-such as acoustical absorptivity, light reflectivity, thermal conductivity, hardness, and water resistancea-of various materials. They use sound, light and temperature sensors to collect data...

Students work as engineers to learn about the properties of molecules and how they move in 3D space through the use of LEGO MINDSTORMS NXT robotics. They design and build molecular models and use different robotic sensors to control the...

Create a creature that uses air to create motion with this challenge. Site includes tips, lesson plans, and a place for students to document their design process.

Build a zoetrope machine where you can animate a facial expression and the machine plays the animation back with this site. Site contains lesson plans, tips, and a place to document your design process.

This USS Constitution Museum resource is a lesson plan that calls for students to work together in teams to create a new figurehead for the USS Constitution that was destroyed while on patrol.

Students learn about global access to clean water and apply the engineering design process to develop a solution to purify water.

Students learn about the concept of pushing, as well as the relationship between force and mass. Students practice measurement skills using pan scales and rulers to make predictions about mass and distance. A LEGO MINDSTORMS NXT robot is...

This collection of Aerospace Engineering learning modules will allow students to explore video and interactive media resources that support the middle and high school Engineering Design core ideas.

Students learn about the components and functions of biosensors. Using LEGO MINDSTORMS NXT robots and sensors, they discover how engineer-designed sensors play important roles in our daily lives, informing people of their surroundings...

Students work as engineers to design and test trebuchets (in this case LEGO MINDSTORMS robots) that can launch objects. During the testing stage, they change one variable at a time to study its effect on the outcome of their designs....

Through investigating the nature, sources and level of noise produced in their environment, students are introduced to the concept of noise pollution. They learn about the undesirable and disturbing effects of noise and the resulting...

Students act as civil engineers developing safe railways as a way to strengthen their understanding of parallel and intersecting lines. Using pieces of yarn to visually represent line segments, students lay down "train tracks" on a...

Students create model elevator carriages and calibrate them, similar to the work of design and quality control engineers. Students use measurements from rotary encoders to recreate the task of calibrating elevators for a high-rise...

Students are introduced to the concept of light pollution by investigating the nature, sources and levels of light in their classroom environment. They learn about the adverse effects of artificial light and the resulting consequences on...

Students learn about traffic lights and their importance in maintaining public safety and order. Using a Parallax Basic Stamp 2 microcontroller, students work in teams on the engineering challenge to build a traffic light with a specific...

Students discover how gears work and how they can be used to adjust a vehicle's power. Specifically, they learn how to build the transmission part of a vehicle by designing gear trains with different gear ratios.

Students design, build and evaluate a spring-powered mouse trap racer. For evaluation, teams equip their racers with an intelligent brick from a LEGO MINDSTORMS NXT Education Base Set and a HiTechnic acceleration sensor. They use...

Students use LEGO MINDSTORMS robotics to help conceptualize and understand the force of friction. Specifically, they observe how different surfaces in contact result in different frictional forces. A LEGO robot is constructed to pull a...

LEED is a program for green building certification. Buildings are rated on a points system in one of five categories, including building design and construction, interior design and construction, building operations and maintenance,...

Students learn about nanocomposites, compression and strain as they design and program robots that compress materials. Student groups conduct experiments to determine how many LEGO MINDSTORMS NXT motor rotations it takes to compress soft...

Students experience haptic (the sense of touch) feedback by using LEGO MINDSTORMS NXT robots and touch sensors to emulate touch feedback recognition. With four touch sensors connected to LEGO NXTs, they design sensor attachments that...

By taking a look at the energy of motion all around us, students learn about the types of energy and their characteristics. They first learn about the two simplest forms of mechanical energy: kinetic and potential energy, as illustrated...

Become an engineer, and design a submarine that moves in the water like a real submarine. Try making it sink, float, and hover in the water.
