Riding the Radio Waves
Through this lesson students learn how AM radios work through basic concepts about waves and magnetic fields. Waves are first introduced by establishing the difference between transverse and longitudinal waves, as well as identifying the amplitude and frequency of a given waveform. Students then learn general concepts about magnetic fields, leading into how radio waves are created and transmitted. Several demonstrations can be performed in order to help students better understand these concepts.
Problem Solve Your School
Students apply what they have learned about the engineering design process to a real-life problem that affects them and/or their school. They chose a problem as a group, and then follow the engineering design process to come up with and test their design solution. This activity teaches students how to use the engineering design process while improving something in the school environment that matters to them. By performing each step of the design process, students can experience what it is like t
Modern Day Pyramids
Students investigate the ways in which ancient technologies — six types of simple machines and combinations — are used to construct modern buildings. As they work together to solve a design problem (designing and building a modern structure), they brainstorm ideas, decide on a design, and submit it to a design review before acquiring materials to create it (in this case, a mural depicting it). Emphasis is placed on cooperative, creative teamwork and the steps of the engineering design proces
This activity is a teacher-led demonstration of continental drift and includes a math worksheet for students involving the calculation of continental drift over time. Students will understand what continental drift is, why it occurs, and how earthquakes occur because of it.
Watch It Slide!
Students use inclined planes as they recreate the difficult task of raising a monolith of rock to build a pyramid. They compare the push and pull of different-sized blocks up an inclined plane, determine the angle of inclination, and learn the changes that happen when the angle is increased or decreased.
Earthquake in the Classroom
Students will learn how engineers construct buildings to withstand damage from earthquakes by building their own structure with toothpicks and marshmallows. Students will test how earthquake-proof their buildings are by testing them on an earthquake simulated in a pan of Jell-O®.
Win that Bid! Selling Your Power Solution
A large part of engineering involves presenting products, concepts, and proposals to others in order to gain approval, funding, contracts, etc. The purpose of this activity is to fine-tune students’ presentation skills while allowing them to independently investigate one type of power production to meet the needs of their region of choice. Students also learn problem solving skills in examining the advantages and disadvantages of particular methods of power generation.
Simple Machines and Modern Day Engineering Analogies
Students apply the mechanical advantages and problem-solving capabilities of six types of simple machines (wedge, wheel and axle, lever, inclined plane, screw, pulley) as they discuss modern structures in the spirit of the engineers and builders of the great pyramids. While learning the steps of the engineering design process, students practice teamwork, creativity and problem solving.
Marine animal tracking
The following lesson is an introduction to the ideas and implications of animal tracking. Animal tracking is a useful method used within science and commercial industries. For instance, when planning the development coastal areas, animal presence and movement should be taken into consideration. The lesson engages students in an activity to monitor animal foraging behavior on a spatial scale. The students will break into groups and track each other’s movements as they move through a pre-determi
Skyscrapers: Engineering Up!
Skyscrapers are one of the most glorified products of Civil Engineering and contain an interesting history of progress and development. In this lesson, the students will learn about the history of the world’s tallest free standing structures and the basic design principles behind their success. Students will build their own newspaper skyscrapers with limited materials and time, trying to achieve a maximum height and the ability to withstand a “hurricane wind” force. Discussion will concent
Testing Fundamental Loads
Students will conduct several simple lab activities to learn about the five fundamental load types that can act on structures: tension, compression, shear, bending, and torsion. In this activity, students break foam insulation blocks by applying these five fundamental load types (tension, compression, shear, bending and torsion). Students will study carefully each type of fracture pattern (break in the material) and make drawings of the fracture patterns in their notes in order to learn the tell
Does Weight Matter?
Using the same method for measuring friction that was used in the previous lesson (Discovering Friction), students design and conduct an experiment to determine if weight added incrementally to an object affects the amount of friction encountered when it slides across a flat surface. After graphing the data from their experiments, students can calculate the coefficients of friction between the object and the surface it moved upon, for both static and kinetic friction.
Light Plants and Dark Plants, Wet Plants and Dry Ones
Students plant sunflower seeds in plastic cups, and once germinated, these are exposed to different conditions of light levels and/or soil moisture contents. During exposure of the plants to these different conditions, students measure growth of the seedlings every few days using non-standard measurement (inch cubes). After a few weeks, they compare the growth of plants exposed to the different conditions, and make pictorial bar graphs that demonstrate these comparisons.
In this lesson, students will determine what supplies they will take with them to survive their trip through the Amazon. Students will use estimation and basic math skills to determine how much they can carry and what they can use to survive in the Amazon and how much they can carry until they reach their destination.
Rocks, Rocks, Rocks
Student teams will test rocks to identify and record rock properties such as luster, hardness, color, etc., and classify rocks as igneous, metamorphic and sedimentary. They will complete a worksheet table with all of their rock properties, and then answer some worksheet questions to deepen their understanding of rock properties and relate them to the cavern design problem.
Testing the Caverns - Optional
This activity provides a fun, activity-based closure to the Asteroid Impact unit. Students build model caverns using paper mache or clay and bury them in a tray of sand. Next, they test the models by dropping balls onto them to simulate an asteroid hitting the earth. By molding paper mache around a balloon to form a dome, or around a small cardboard box to form a rectangular structure, students will be able to build their caverns.
Scaling the Map
Students will learn how to determine map distances and map areas using the map scale. They will also get a better feel for how much an area represents on the map in relation to the size they are suggesting for their cavern.
Flow Rates of Faucets and Rivers
In the Flow Rate Experiment, students perform hands-on experiments with a common faucet, as well as work with the Engineering Our Water Living Lab (accessible through TeachEngineering.com) to gain a better understanding of flow rate and how it pertains to engineering and applied science. Students calculate the flow rate of a faucet for three different levels (quarter blast, half blast, and full blast). Building on these calculations, students hypothesize about the flow rate in a nearby river, an
Bend That Bar
In this activity, the students will learn about material properties. They will learn that engineers must consider several material properties when designing. This activity focuses on strength-to-weight ratios and how sometimes the strongest material is not always the best material.
Poly (lactic-co-glycolic acid) (PLGA) porous scaffold for tissue engineering.
The patients own cells are seeded onto the scaffold and allowed to attach and start producing new bone. The construct is implanted into the defect site, where eventually the polymer will biodegrade and be completely removed, leaving a natural autogenous bone graft. Average Pore Size 100-300 micrometre+D7, porosity estimated at 65%.
