Continuing the Asteroid Impact challenge, student teams test rocks to identify their physical properties such as luster, hardness, color, etc., and classify them as igneous, metamorphic or sedimentary. They complete a data table to record all of the rock properties, and then answer worksheet questions to deepen their understanding of rock properties and relate them to the cavern design problem.

This activity focuses on the use of graphene in organic fibers, and their applications in organic electronics, e-textiles and wearable technologies. Students learn about the properties of graphene—a unique form of carbon—and how graphene-based fibers are fabricated, how to measure resistance, how to calculate resistivity, and how a material changes its electrical properties. Students also learn about the importance of defining design parameters, which is an important concept in the engineering design process. Students create graphite-based fibers using sodium alginate as the medium and a calcium coagulation bath, which is similar to the way in which graphene-based fibers are created in engineering research laboratories. Students then determine the factors that contribute to resistivity and vary these parameters to optimize fiber resistivity.

Student groups are challenged to design and construct model towers out of newspaper. They are given limited supplies including newspaper, tape and scissors, paralleling the real-world limitations faced by engineers, such as economic restrictions as to how much material can be used in a structure. Students aim to build their towers for height and stability, as well as the strength to withstand a simulated lateral "wind" load.

Students explore the physics exploited by engineers in designing today's roller coasters, including potential and kinetic energy, friction and gravity. First, they learn that all true roller coasters are completely driven by the force of gravity and that the conversion between potential and kinetic energy is essential to all roller coasters. Second, they consider the role of friction in slowing down cars in roller coasters. Finally, they examine the acceleration of roller coaster cars as they travel around the track. During the associated activity, students design, build and analyze model roller coasters they make using foam tubing and marbles (as the cars).

Students learn about oil spills and their environmental and economic effects. They experience the steps of the engineering design process, starting by brainstorming potential methods for oil spill cleanup. They model small-size oil spills in plastic bins, and then design, build and re-design oil booms to prevent the spread of oil spills. Oil booms are like floating fences on the water surface to help contain and collect spilled oil. During a reflective session after cleaning up their oil booms, students come up with ideas on how to reduce oil consumption to prevent future oil spills. A PowerPoint presentation is provided.

Students learn the basics of the electromagnetic spectrum and how various types of electromagnetic waves are related in terms of wavelength and energy. In addition, they are introduced to the various types of waves that make up the electromagnetic spectrum including, radio waves, ultraviolet waves, visible light and infrared waves. These topics help inform students before they turn to designing solutions to an overarching engineering challenge question.

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.

Music - Daily_Beetle

Student pairs are given 10 minutes to create the biggest box possible using one piece of construction paper. Teams use only scissors and tape to each construct a box and determine how much puffed rice it can hold. Then, to meet the challenge, they improve their designs to create bigger boxes. They plot the class data, comparing measured to calculated volumes for each box, seeing the mathematical relationship. They discuss how the concepts of volume and design iteration are important for engineers. Making 3-D shapes also supports the development of spatial visualization skills. This activity and its associated lesson and activity all employ volume and geometry to cultivate seeing patterns and understanding scale models, practices used in engineering design to analyze the effectiveness of proposed design solutions.

This unique engineering activity explores helping animals that cannot help themselves. Students perform research and design prosthetic prototypes for an animal to use for its survival. First, students choose an animal from a set of task cards. These cards have descriptions of animals that have injuries that keep them from getting what they need in the wild. Next, students work in pairs to research these animals and their habitats. They then create habitats for their animals to live and model 3D prosthetics for the animals to use with modeling clay. Finally, students share their habitats with their peers.

Music: Believer - Silent Partner

Students move through the engineering design process as they write Arduino code and use a “digital sandbox” to create new colors out of the three programming primary colors: green, red and blue. They develop their own functions, use them to make disco light shows, and vary the pattern and colors of their shows. The digital sandbox is a hardware and software learning platform powered by a microcontroller that can interact with real-world inputs like light, while at the same time controlling LEDs and other outputs.

Music: EDM Detection Mode

This activity demonstrates how potential energy (PE) can be converted to kinetic energy (KE) and back again. Given a pendulum height, students calculate and predict how fast the pendulum will swing by understanding conservation of energy and using the equations for PE and KE. The equations are justified as students experimentally measure the speed of the pendulum and compare theory with reality.

In this engineering design activity, students build models of natural sources of water. As they move through the design process, students differentiate between natural sources of water (such as rivers or lakes) and human-made sources of water, such as reservoirs or canals. Students learn how engineers can study natural sources of water to create better water delivery systems that benefit society.
This engineering curriculum aligns to Next Generation Science Standards (NGSS).

Music: Bella Bella Beat - Nana Kwabena

Students explore the concept of biodegradability by building and observing model landfills to test the decomposition of samples of everyday garbage items. They collect and record experiment observations over five days, seeing for themselves what happens to trash when it is thrown "away" in a landfill environment. This shows them the difference between biodegradable and non-biodegradable and serves to introduce them to the idea of composting. Students also learn about the role of engineering in solid waste management.

Music: Undeniable

Students learn about gear ratios and power by operating toy mechanical cranes of differing gear ratios. They attempt to pick up objects with various masses to witness how much power must be applied to the system to oppose the force of gravity. They learn about the concept of gear ratio and practice calculating gear ratios on worksheets, discovering that smaller gear ratios are best for picking objects up quickly, and larger gear ratios make it easier to lift heavy objects.

Students explore how pendulums work and why they are useful in everyday applications. In a hands-on activity, they experiment with string length, pendulum weight and angle of release. In an associated literacy activity, students explore the mechanical concept of rhythm, based on the principle of oscillation, in a broader biological and cultural context — in dance and sports, poetry and other literary forms, and communication in general.

Students first explore different materials to see what types reduce the most amount of sound when placed in a box. Each group is assigned a different material and they fill their box with that specific material. Students measure the sound level of a tone playing from inside the box using a decibel reader from outside the box. Students share this data with the class and analyze which types of materials absorb the most sound and which reflect the most sound.
