TeachEngineering NGSS Aligned Records
"Overview: The difference between an architect and an engineer is sometimes confusing because their roles in building design can be similar. Students experience a bit of both professions by following a set of requirements and meeting given constraints as they...

Swamp Cooler
"Overview: Using a household fan, cardboard box and paper towels, student teams design and build their own evaporative cooler prototype devices. They learn about the process that cools water during the evaporation of wat...
Survive That Tsunami!
"Overview: 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. Stu...
Surgical Device Engineering
"Overview: This unit focuses on teaching students about the many aspects of biomedical engineering (BME). Students come to see that BME is a broad field that relies on concepts from many engineering disciplines. They als...
Surf's Up!
"Overview: 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...
Surfactants: Helping Molecules Get Along
"Overview: 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...
Surface Tension and Suminagashi
"Overview: 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...
Surface Tension Lab
"Overview: Students extend their understanding of surface tension by exploring the real-world engineering problem of deciding what makes a ""good"" soap bubble. Student teams first measure this property, and then use thi...
Surface Tension Basics
"Overview: Students are presented with the question: ""Why does a liquid jet break up into droplets?"" and introduced to its importance in inkjet printers. A discussion of cohesive forces and surface tension is included,...
Surface Tension
"Overview: Surface tension accounts for many of the interesting properties we associate with water. By learning about surface tension and adhesive forces, students learn why liquid jets of water break into droplets rathe...
Superhydrophobicity: The Lotus Effect
"Overview: Students are introduced to superhydrophobic surfaces and the ""lotus effect."" Water spilled on a superhydrophobic surface does not wet the surface, but simply rolls off. Additionally, as water moves across th...
Super Spinners!
Super Spinners! "Overview: Use this hands-on activity to demonstrate rotational inertia, rotational speed, angular momentum, and velocity. Students build at least two simple spinners to conduct experiments with different...
Super Slinger Engineering Challenge
"Overview: Students are challenged to design, build and test small-scale launchers while they learn and follow the steps of the engineering design process. For the challenge, the ""slingers"" must be able to aim and laun...
Sumobot Challenge
"Overview: Students apply their knowledge of constructing and programming LEGO MINDSTORMS (TM)NXT robots to create sumobots - strong robots capable of pushing other robots out of a ring. To meet the challenge, groups fol...
Sum It Up: An Introduction to Static Equilibrium
"Overview: Students are introduced to static equilibrium by learning how forces and torques are balanced in a well-designed engineering structure. A tower crane is presented as a simplified two-dimensional case. Using Po...
Suit Up!
"Overview: Students learn about providing healthcare in a global setting and the importance of wearing protective equipment when treating patients with infectious diseases like Ebola. They learn about biohazard suits, he...

Sugar Spill!
"Overview: In this activity, students act as environmental engineers involved with the clean up of a toxic spill. Using bioremediation as the process, students select which bacteria they will use to eat up the pollutant...
Sudsy Cells
"Overview: Students culture cells in order to find out which type of surfactant (in this case, soap) is best at removing bacteria. Groups culture cells from unwashed hands and add regular bar soap, regular liquid soap, a...
Studying Evolution with Digital Organisms
"Overview: Students observe natural selection in action and investigate the underlying mechanism, including random mutation and differential fitness based on environmental characteristics. They do this through use of the...
Strum Along
"Overview: Music and sound are two different concepts that share much in common. Determining the difference between the two can sometimes be difficult due to the subjective nature of deciding what is or is not music. The...
