IF YOU BUILD IT
Engineering in the Classroom
Humans have faced problems since time began. An early man finds the perfect cave to live in, but a large, heavy boulder blocks the entrance. How can he move the boulder to make his home? He looks closely and sees a crack in the rock. He finds a smaller rock and pounds it into the crack. The boulder splits, and he can move the smaller pieces. The wedge was born, and early man learned to use it more easily to split rocks or wood. He engineered a solution to the problem at hand.
Engineering is an important part of STEAM (Science, Technology, Engineering, Art, and Mathematics) Education. It uses science and math to solve problems. Engineers take the theories and inventions created by scientists and mathematicians, figure out how to use them, and put them to practical use.
Simple machines are the earliest products of engineering. Early people identified a problem in their world and engineered (or devised) a way to solve their problems. Levers, wedges, and pulleys were created to move heavy things in the world. The wheel transformed the world and made moving people and things much easier.
As civilizations developed, engineering advanced as well. The ancient civilizations created engineering feats known as the Seven Wonders of the Ancient World. For example, ancient Egyptians built the Pyramids at Giza with three simple machines - the inclined plane, the lever, and the wedge.
The Muslim world during the Middle Ages gave the world many early engineering designs that set the stage for the modern world. The great minds of the era harnessed the power of the wind to create windmills and windpumps. The spinning wheel was invented during this time, and the first programmable machine was developed.
Engineering became a profession during the 1700s and grew during the Industrial Revolution. As the industry grew, people needed more efficient ways to meet demands. Engineers used science and math to solve the newly presented problems. Engineers designed canals and bridges to move products. Waterwheels supplied power to mills. From water to steam, engineers learned to harness steam, which led to the steam engine. Steamboats and steam engines were developed to move people and goods.
As time progressed, the movement of people, goods, and information became a catalyst for engineers. Engineering is divided into five major branches. Electrical engineering came out of the development of the electric telegraph and the electric motor. The field expanded as electricity became more widely used. As the world took to the skies, the field of aeronautical engineering was born. Civil engineering focuses on designing and implementing infrastructure such as bridges, roads, railways, and water supply. Mechanical engineering focuses on automated systems such as engines, compressors, robotics, and manufacturing. The final main branch of engineering is chemical engineering. This area of focus includes petroleum refining, commercial chemicals, and fermentation.
Engineers follow the Engineering Design Process to find solutions to presented problems. First, engineers define the problem and research the end users or existing solutions. Next, they will specify the design requirements and brainstorm multiple solutions. After analyzing and discussing the solutions, engineers will choose and refine the best solution. Then they will build and test a prototype. Throughout the process, teams will use the data to make changes and redesign, rebuild, or retest. Finally, engineers will communicate the results once the problem has been solved to the design specifics.
Engineering has solved many world problems and made it easier to move people, goods, and information. Using math and science to solve practical problems has propelled society forward since early man.

- Play various engineering games on PBSKids.org or TryEngineering (TeachesFirst review). TryEngineering offers many STEM games across various fields and at all age levels.
- Watch a TEDed video about different elements of engineering. Use EdPuzzle (TeachersFirst review) to add notes for students to view, quizzes, and more to help students focus on the content in the video.
- Challenge students to build a birdhouse. (To incorporate literature, pair the activity with The Best Nest by P. D. Eastman - ISBN 978-0394800516). Create a class book to share with family and friends that includes pictures of student-created birdhouses along with audio descriptions of how students built their birdhouses. Book Creator (TeachersFirst review) is an easy-to-use book creation tool for students of all ages.
- Learn more about the Engineering Design Process with this video from CrashCourseKids. Test the design process by making a Balloon Hovercraft.
Pair Engineering and Coding
- Encourage students to create a maze in the classroom. Use any handy materials - textbooks, boxes, blocks, etc. If robots (Sphero, Beebots, Bluebots, Blockley, Dash) are available, students can use digital coding to move the robot through the maze. If robots are unavailable, use arrow cards to move something through the maze.
- Find many more ideas for coding on TeachersFirst Edge Coding Resources located here.
- Introduce students to the Design Squad on PBS. Bring the challenge to your classroom with the Design Squad Challenge. For added fun, challenge students to complete a task that appears in a Design Squad episode. After they complete the challenge, show the episode and compare ideas and solutions.
