Students explore whether rooftop gardens are a viable option for combating the urban heat island effect. Can rooftop gardens reduce the temperature inside and outside houses? Teams each design and construct two model buildings using foam core board, one with a "green roof" and the other with a black tar paper roof. They measure and graph the ambient and inside building temperatures while under heat lamps and fans. Then students analyze the data and determine whether the rooftop gardens are beneficial to the inhabitants.

Students learn about the types of possible loads, how to calculate ultimate load combinations, and investigate the different sizes for the beams (girders) and columns (piers) of simple bridge design. They learn the steps that engineers use to design bridges by conducting their own hands on associated activity to prototype their own structure. Students will begin to understand the problem, and learn how to determine the potential bridge loads, calculate the highest possible load, and calculate the amount of material needed to resist the loads.

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.

Students learn about the variety of materials used by engineers in the design and construction of modern bridges. They also find out about the material properties important to bridge construction and consider the advantages and disadvantages of steel and concrete as common bridge-building materials to handle compressive and tensile forces.

Students learn about the underlying engineering principals in the inner workings of a simple household object – the faucet. Students use the basic concepts of simple machines, force and fluid flow to describe the path of water through a simple faucet. Lastly, they translate this knowledge into thinking about how different designs of faucets also use these same concepts.

Students conduct a research-based activity to explore, graph, and evaluate the speed of slime, or how far and at what rate slime stretches. During the activity, the students review the major concepts of graphing speed by stretching gum or silly putty. After reviewing how to create and read speed on a graph, students create a “super-stretchy” slime sample. Students conduct tensile tests to determine the fastest speed the slime can stretch without snapping. Students analyze the slime stretching data by compiling it in a speed graph using Google Sheets or Microsoft Excel. Lastly, students communicate their findings through a poster presentation.

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.

Students learn the basics of the electromagnetic spectrum and how various types of electromagnetic waves are related in terms of wavelength and energy. In addition, they are introduced to the various types of waves that make up the electromagnetic spectrum including, radio waves, ultraviolet waves, visible light and infrared waves. These topics help inform students before they turn to designing solutions to an overarching engineering challenge question.

Students conduct a simple experiment to model and explore the harmful effects of acid rain (vinegar) on living (green leaf and eggshell) and non-living (paper clip) objects.

Students follow weather forecasts to gauge their accuracy and produce a weather report for the class. They develop skills of observation, recording and reporting.

Students discover how tiny microscopic plants can remove nutrients from polluted water. They also learn how to engineer a system to remove pollutants faster and faster by changing the environment for the algae.

Students are introduced to the structure, function and purpose of locks and dams, which involves an introduction to Pascal's law, water pressure and gravity.

This lesson begins with a brief history of robotics, describing how robots are beneficial to engineering and society and then explores how robots have been used in recent space exploration efforts. The engineering design of the Mars rovers, Spirit, Opportunity, and Curiosity, are examples of advanced engineering design for space research. The maneuverability of these spacecraft's robotic arms and the functionality of their tools are discussed.

Simple machines are devices with few or no moving parts that make work easier. Students are introduced to the six types of simple machines — the wedge, wheel and axle, lever, inclined plane, screw, and pulley — in the context of the construction of a pyramid, gaining high-level insights into tools that have been used since ancient times and are still in use today. In two hands-on activities, students begin their own pyramid design by performing materials calculations, and evaluating and selecting a construction site. The six simple machines are examined in more depth in subsequent lessons in this unit.

In this lesson, students learn the basics of the analysis of forces engineers perform at the truss joints to calculate the strength of a truss bridge. This method is known as the “method of joints.” Finding the tensions and compressions using this method will be necessary to solve systems of linear equations where the size depends on the number of elements and nodes in the truss. The method of joints is the core of a graphic interface created by the author in Google Sheets that students can use to estimate the tensions-compressions on the truss elements under given loads, as well as the maximum load a wood truss structure may hold (depending on the specific wood the truss is made of) and the thickness of its elements.
