Using scientific principles to invent, design, develop, test, refine, build, maintain and improve structures, machines, devices, systems, materials and processes, in order to produce solutions or products; application of science, technology, engineering and mathematics.

• ### Balloon Blast

Lesson

Students devise a plan to measure the distance of a balloon’s flight, predict the direction a balloon will travel as it deflates, and learn about Newton's Laws of Motion.

• ### Boomerangs

Lesson

Students explore aerodynamic lift, gyroscopic precession, drag and gravity by designing and flying boomerangs.

• ### Catapults

Lesson

Students explore physical energy and mechanical energy as they design, build and test catapults.

• ### Developing an Object or Tool

Lesson

Students sequence the process of making an object (tree to chair, mud to brick, etc.), and learn tools and objects are designed to perform a function or solve a problem.

• ### Fossil Fuels and the Carbon Cycle

Lesson

Students learn how geologists locate fossil fuels by using a straw to extract "core samples" from a model that has different layers.

• ### Humans Design Their Homes

Lesson

Students create models of living spaces (houses) for people in different climates with different available resources; and compare the strengths and weaknesses of the different designs.

• ### Is It Natural or Transformed?

Lesson

Students examine, compare, discuss and sort materials as natural or transformed (changed or processed by humans).

• ### Javelin Rockets

Lesson

Student teams construct javelin rockets and use them to investigate the relationship between launch angle and the distance an object travels.

• ### Kinetic Art

Lesson

Students create and study unique sculptures that move in interesting ways when acted upon by the force of the wind.

• ### Make a Processed Food

Lesson

Each student prepares a processed food (frozen banana pop) and eats the product.

• ### Raw vs. Processed Food

Lesson

Students gain an understanding of what “processed” means.  They also distinguish between natural and processed foods, and learn about sources of some foods.

• ### Ring-wing Gliders

Lesson

Students make and test flying tubes, called ring wing gliders, as they learn about Isaac Newton’s Third Law of Motion and use an engineer's approach to problem-solving.

• ### Rocket Cars: Rocket Races

Lesson

Students learn about Newton’s Three Laws of Motion as they construct and test a lightweight “rocket” car propelled by the action/reaction force of air escaping from an inflated balloon.

• ### Rockets

Lessons

Students learn about engineering and design principles by designing, building, launching, testing and redesigning their own rockets. (Grades: K-2, 3-5 or 6-8)

• ### Roller Coasters

Lesson

Students build roller coasters from foam insulation tubing and use marbles as the roller coaster cars.

• ### Wind-up Racers

Lesson

Students explore kinetic energy and potential energy as they build and test simple racers.

• ### Force, Motion, Friction and Energy
