Students investigate motors and electromagnets as they construct their own simple electric motors using batteries, magnets, paper clips and wire.
Students are introduced to gear transmissions and gear ratios using LEGO MINDSTORMS(TM) NXT robots, gears and software. They discover how gears work and how they can be used to adjust a vehicle's power. Specifically, they learn how to build the transmission part of a vehicle by designing gear trains with different gear ratios. Students quickly recognize that some tasks require vehicle speed while others are more suited for vehicle power. They are introduced to torque, which is a twisting force, and to speed the two traits of all rotating engines, including mobile robots using gears, bicycles and automobiles. Once students learn the principles behind gear ratios, they are put to the test in two simple design activities that illustrate the mechanical advantages of gear ratios. The "robot race" is better suited for a quicker robot while the "robot push" calls for a more powerful robot. A worksheet and post-activity quiz verify that students understand the concepts, including the tradeoff between torque and speed.
Students take part in a hypothetical scenario that challenges them to inform customers at a local restaurant of how their use and disposal of plastics relates/contributes to the Great Pacific garbage patch (GPGP). What students ultimately do is research information on the plastics pollution in the oceans and present that information as a short, eye-catching newsletter suitable to hand out to restaurant customers. This activity focuses on teaching students to conduct their own research on a science-technology related topic and present it in a compelling manner that includes citing source information without plagiarism. By doing this, students gain experience and skills with general online searching as well as word processing and written and visual communication.
In this lesson, students will investigate error. As shown in earlier activities from navigation lessons 1 through 3, without an understanding of how errors can affect your position, you cannot navigate well. Introducing accuracy and precision will develop these concepts further. Also, students will learn how computers can help in navigation. Often, the calculations needed to navigate accurately are time consuming and complex. By using the power of computers to do calculations and repetitive tasks, one can quickly see how changing parameters likes angles and distances and introducing errors will affect their overall result.
In this lesson, students learn how to determine location by triangulation. We describe the process of triangulation and practice finding your location on a worksheet, in the classroom, and outdoors.
The Girls Who Build Cameras workshop for high school girls is a one-day, hands-on introduction to camera physics and technology (i.e. how Instagram works!) at the MIT Lincoln Laboratory Beaverworks Center. The workshop includes tearing down old dSLR cameras, building a Raspberry Pi camera, and designing Instagram filters and Photoshop tools. Participants also get to listen to keynote speakers from the camera technology industry, including Kris Clark who engineers space cameras for NASA and MIT Lincoln Laboratory, and Uyanga Tsedev who creates imaging probes to help surgeons find tumors at MIT
The Girls Who Build: Make Your Own Wearables workshop for high school girls is an introduction to computer science, electrical and mechanical engineering through wearable technology. The workshop, developed by MIT Lincoln Laboratory, consists of two major hands-on projects in manufacturing and wearable electronics. These include 3D printing jewelry and laser cutting a purse, as well as programming LEDs to light up when walking. Participants learn the design process, 3D computer modeling, and machine shop tools, in addition to writing code and building a circuit.
In this activity students practice measuring techniques by measuring different objects and distances around the classroom. They practice using different scales of measurement in metric units and estimation.
This resources identifies best practices for giving presentations or talks in elementary classrooms and was developed to help scientists and engineers who have been asked to visit an elementary classroom. It provides helpful suggestions before, during, and after the presentation, as well questions for the teacher (e.g., what content do you want me to cover, what have students already learned about this content?).
This resources identifies best practices for giving presentations or talks in middle school classrooms and was developed to help scientists and engineers who have been asked to visit a middle school classroom. It provides helpful suggestions before, during, and after the presentation, as well questions for the teacher (e.g., what content do you want me to cover, what have students already learned about this content?).
This hands-on activity explores five different forms of erosion (chemical, water, wind, glacier and temperature). Students rotate through stations and model each type of erosion on rocks, soils and minerals. The students record their observations and discuss the effects of erosion on the Earth's landscape. Students learn about how engineers are involved in the protection of landscapes and structures from erosion. Math problems are included to help students think about the effects of erosion in real-world scenarios.
This manual provides simple demonstrations to show how lenses and mirrors are used to create telescopes. It was created for use by the Night Sky Network of astronomy clubs.
This class is designed to expose you to the cycles of disasters, the roots of emergency planning in the U.S., how to understand and map vulnerabilities, and expose you to the disaster planning in different contexts, including in developing countries.
Students learn how the greenhouse effect is related to global warming and how global warming impacts our planet, including global climate change. Extreme weather events, rising sea levels, and how we react to these changes are the main points of focus of this lesson.
Building adequate housing is a pressing issue worldwide. With close to a billion people currently living in slums, accommodating a growing population, and improving dwelling conditions is a critical issue for society.
This challenge cannot be solved with a one-size-fits-all approach. Every city, region and country demand their own housing models and prototypes. That’s why housing design needs to negotiate many aspects simultaneously to achieve sustainable urban environments and inclusive dwelling communities.
This course uncovers how social, economic and environmental factors are interrelated in the design of housing settlements. For this, the course dives into three key aspects that anyone involved in housing design should take into consideration: time, environment, and community. Each of these aspects will be examined through a specific design approach, respectively:
Incrementality: how dwelling environments should be able to accommodate growth and change through time.
Typology Mix: how design can be responsive to different patterns of inhabitation, aspirations and cultural backgrounds, creating inclusive dwelling environments.
Clustering: what methods and strategies can shape the association of dwelling units in order to create meaningful communities.
This video segment adapted from NOVA/FRONTLINE looks at the future of global warming as developing nations, including India and China, increase their need for energy.
Students learn about the engineering design process and how products may be reinvented to serve new purposes. Working in groups, students design a type of slime. After creating their slime, the teacher turns out the lights and the students see that the slime they made actually glows in the dark! The groups investigate how to take their new discoveries and apply them to industrial applications. Once they have determined a use for their glowing slime, each group must build/design and test their product outside of class. The groups then create advertisements (videos, brochures, performances, etc.) for their new product(s) or application(s), and present to the judges for review similar to a “Shark Tank” environment.
Student teams learn about engineering design of green fluorescent proteins (GFPs) and their use in medical research, including stem cell research. They simulate the use of GFPs by adding fluorescent dye to water and letting a flower or plant to transport the dye throughout its structure. Students apply their knowledge of GFPs to engineering applications in the medical, environmental and space exploration fields. Due to the fluorescing nature of the dye, plant life of any color, light or dark, can be used unlike dyes that can only be seen in visible light.
Students combine art, gaming culture and engineering by fabricating light-up patches to increase youngsters’ visibility at night. The open-ended project is presented as a hypothetical design challenge: Students are engineers who have been asked by a group of parents whose children go out Pokémon hunting at night to create glowing patches that they adhere to clothing or backpacks to help vehicle drivers see the kids in the dark. Student pairs create Pokémon character stencil designs cut from iron-on fabric patches, adding transparent layers for color. Placed over an EL (electroluminescent) panel that is connected to a battery pack, the stencils create glowing designs. Each team creates a circuit, which includes lengthening the EL panel wiring to make it easier to wear. Then they sew/adhere the patches onto hoodies, messenger bags, hats, pockets or other applications they dream up. The project concludes with team presentations as if to an audience of project clients. Keep the project simple by hand cutting and ironing/sewing, or use cutting machines, laser cutters and sewing machines, if available.
Students use hot glue gun sticks to learn about the forces of tension, compression and torsion.
