In an activity that integrates science and art, students see, experience and harness the phenomenon of surface tension as they create beautiful works of art. Students conduct two experiments related to surface tension floating objects on the surface of water and creating original artwork using floating inks. They also learn historical and cultural information through an introduction to the ancient Japanese art form of suminagashi. They take the topic a step further by discussing how an understanding of surface tension can be applied to solve real-world engineering problems and create useful inventions.

Students learn about the basics of molecules and how they interact with each other. They learn about the idea of polar and non-polar molecules and how they act with other fluids and surfaces. Students acquire a conceptual understanding of surfactant molecules and how they work on a molecular level. They also learn of the importance of surfactants, such as soaps, and their use in everyday life. Through associated activities, students explore how surfactant molecules are able to bring together two substances that typically do not mix, such as oil and water. This lesson and its associated activities are easily scalable for grades 3-12.

This lesson introduces the concepts of longitudinal and transverse waves. Students see several demonstrations of waves and characterize them by transverse and longitudinal behavior. This lesson also introduces the Sunken Treasure theme of the Sound and Light unit a continuous story line throughout the lessons.

Students use a table-top-sized tsunami generator to observe the formation and devastation of a tsunami. They see how a tsunami moves across the ocean and what happens when it reaches the continental shelf. Students make villages of model houses and buildings to test how different material types are impacted by the huge waves. They further discuss how engineers design buildings to survive tsunamis. Much of this activity setup is the same as for the Mini-Landscape activity in Lesson 4 of the Natural Disasters unit.

Students are introduced to the basic biology behind Pacific salmon migration and the many engineered Columbia River dam structures that aid in their passage through the river's hydroelectric dams. Students apply what they learn about the salmon life cycle as they think of devices and modifications that might be implemented at dams to aid in the natural cycle of fish migration, and as they make (hypothetical) Splash Engineering presentations about their proposed fish mitigation solutions for Birdseye River's dam in Thirsty County.

Students experientially learn about the characteristics of a simple physics phenomenon the pendulum by riding on playground swings. They use pendulum terms and a timer to experiment with swing variables. They extend their knowledge by following the steps of the engineering design process to design timekeeping devices powered by human swinging.

In this hands-on activity, students construct a simple switch and determine what objects and what types of materials can be used to close a switch in a circuit and light a light bulb.

Students come to understand static electricity by learning about the nature of electric charge, and different methods for charging objects. In a hands-on activity, students induce an electrical charge on various objects, and experiment with electrical repulsion and attraction.

This lesson introduces students to the art of designing an airplane through paper airplane constructions. The goal is that students will learn important aircraft design considerations and how engineers must iterate their designs to achieve success. Students first follow several basic paper airplane models, after which they will then design their own paper airplane. They will also learn how engineers make models to test ideas and designs.

Students learn how scientific terms are formed using Latin and Greek roots, prefixes and suffixes, and on that basis, learn to make an educated guess about the meaning of a word. Students are introduced to the role played by metaphor in language development.

In this activity, the students will apply the concepts they learned regarding mass, volume and density in the previous activities to design a boat.

Students conduct an experiment to determine whether or not the sense of smell is important to being able to recognize foods by taste. They do this by attempting to identify several different foods that have similar textures. For some of the attempts, students hold their noses and close their eyes, while for others they only close their eyes. After they have conducted the experiment, they create bar graphs showing the number of correct and incorrect identifications for the two different experimental conditions tested.

The goal of this activity is for students to develop visual literacy. They learn how images are manipulated for a powerful effect and how a photograph can make the invisible (pollutants that form acid rain) visible (through the damage they cause). The specific objective is to write captions for photographs.

Students are introduced to the health risks caused by cooking and heating with inefficient cook stoves inside homes, a common practice in rural developing communities. Students simulate the cook stove scenario and use the engineering design process, including iterative trials, to increase warmth inside a building while reducing air quality problems. Students then collect and graph data, and analyze their findings.

Students see how different levels of surface tension affect water's ability to move. Teams "race" water droplets down tracks made of different materials, making measurements, collecting data, making calculations, graphing results and comparing to their predictions and the properties of each surface, determining which surface exhibits the highest (or lowest) level of surface tension with water. They apply their results to make engineering recommendations for real-world applications.

Students learn about wind as a source of renewable energy and explore the advantages and disadvantages wind turbines and wind farms. They also learn about the effectiveness of wind turbines in varying weather conditions and how engineers work to create wind power that is cheaper, more reliable and safer for wildlife.

With the challenge to program computers to mimic the human reaction after touching a hot object, students program LEGO® robots to "react" and move back quickly once their touch sensors bump into something. By relating human senses to electronic sensors used in robots, students see the similarities between the human brain and its engineering counterpart, the computer, and come to better understand the functioning of sensors in both applications. They apply an understanding of the human "stimulus-sensor-coordinator-effector-response" framework to logically understand human and robot actions.

In this activity, students will review and evaluate the ways land is covered and used in their local community. They will also consider the environmental effects of the different types of land use. Students will act as community planning engineers to determine where to place a new structure that will have the least effect on the environment.

In this activity, students work as engineers to build and observe a model landfill. They will understand the process and pitfalls of the use of landfills as a method for the waste disposal.

Students are introduced to the engineering design process, focusing on the concept of brainstorming design alternatives. They learn that engineering is about designing creative ways to improve existing artifacts, technologies or processes, or developing new inventions that benefit society. Students come to realize that they can be engineers and use the design process themselves to create tomorrow's innovations.
