Students see how surface tension can enable light objects (paper clips, peppercorns) to float on an island of oil in water, and subsequently sink when the surface tension of the oil/water interface is reduced by the addition of a surfactant; such as ordinary dish soap.

Students practice creating rudimentary detail drawings. They learn how engineers communicate the technical information about their designs using the basic components of detail drawings. They practice creating their own drawings of a three-dimensional block and a special LEGO piece, and then make 3D sketches of an unknown object using only the information provided in its detail drawing.

Students use a compass and a permanent magnet to trace the magnetic field lines produced by the magnet. By positioning the compass in enough spots around the magnet, the overall magnet field will be evident from the collection of arrows representing the direction of the compass needle. In activities 3 and 4 of this unit, students will use this information to design a way to solve the grand challenge of separating metal for a recycling company.

This Super Lesson utilizes Project Based Learning to assist learners with designing, building, and testing flying contraptions as an introduction to Engineering. The goal of this project is to engage students in collaborative team work and to introduce students to the Science and Engineering Practices: Asking Questions and Defining Problems, Planning and Carrying Out Investigations, and Constructing Explanations and Designing Solutions.
We have offered this Super Lesson as an 8-week elective course, developing and strengthening student interest in applied Math and Science topics. It could also be offered within upper elementary or middle school Science and Math courses. In addition, each week’s topic could be used as a stand alone mini-lesson if time is limited. We have worked to include multiple options within this unit to make it accessible to both general education and special education programs, including recommendations for modifications and extensions.

In this design activity, students investigate materials engineering as it applies to weather and clothing. Teams design and analyze different combinations of materials for effectiveness in specific weather conditions. Analysis includes simulation of temperature, wind and wetness elements, as well as the functionality and durability of final prototypes.

This is a lesson about spacecraft design. Learners will use the information learned in previous lessons, combined with their own creativity and problem-solving skills, to design and test a parachuting probe that will withstand a fall from a high point, land intact, be able to descend slowly, float in liquid, and cost the least to launch into space. Extensions provide an option if the teacher has limited time, and invite the students to simulate other experiments that will be carried out by the Huygens probe. This is lesson 9 of 12 in the Mission to Saturn Educators Guide, Reading Writing Rings, for grades 3-4.

Today we’re talking about mass transfer. It doesn’t just apply to objects and fluids as a whole, but also to the individual molecules and components that make them up. We’ll see that transfers of mass need their own driving force, discuss diffusion, and use Fick’s Law to help us model mass transfer.

Biological systems (e.g. cells) can make stochastic transitions between phenotypes (e.g. states of relatively increased or decreased drug resistance). This means that an initially drug-sensitive population can generate relatively drug-resistant subpopulations. This video presents a metronomogram, which is a tool for understanding whether such stochastic transitions can provide an opportunity for therapeutic treatment.

Students further their understanding of the engineering design process (EDP) while applying researched information on transportation technology, materials science and bioengineering. Students are given a fictional client statement (engineering challenge) and directed to follow the steps of the EDP to design prototype patient safety systems for small-size model ambulances. While following the steps of the EDP, students identify suitable materials and demonstrate two methods of representing solutions to the design challenge (scale drawings and small-scale prototypes). A successful patient safety system meets all of the project's functions and constraints, including the model patient (a raw egg) "surviving" a front-end collision test with a 1:8 ramp pitch.
