In this lesson, students are introduced to both potential energy and kinetic energy as forms of mechanical energy. A hands-on activity demonstrates how potential energy can change into kinetic energy by swinging a pendulum, illustrating the concept of conservation of energy. Students calculate the potential energy of the pendulum and predict how fast it will travel knowing that the potential energy will convert into kinetic energy. They verify their predictions by measuring the speed of the pendulum.

Growing up I recognized the various inequities that are perpetuated in education; therefore, I have dedicated the majority of my career to examining, teaching about, and alleviating educational disparities. As an Educator, for 15+ years, I focus on enlightening students with new knowledge, optimizing their skills, and growing their career potential. I earned my Ph.D. in Education from UCLA and am currently an Associate Professor in Child and Family Studies at Cal State LA. My teaching experiences range across various age groups but I particularly enjoy teaching college students. I teach courses on lifespan development, diversity and resilience, research methods, and child and family advocacy.

Students use a LEGO® ball shooter to demonstrate and analyze the motion of a projectile through use of a line graph. This activity involves using a method of data organization and trend observation with respect to dynamic experimentation with a complex machine. Also, the topic of line data graphing is covered. The main objective is to introduce students graphs in terms of observing and demonstrating their usefulness in scientific and engineering inquiries. During the activity, students point out trends in the data and the overall relationship that can be deduced from plotting data derived from test trials with the ball shooter.

Students gain first-hand experience with the steps of the scientific method as well as the overarching engineering design process as they conduct lab research with the aim to create a bioplastic with certain properties. Students learn about the light mechanism that causes ultraviolet bead color change, observe the effect of different light waves on a phosphorescence powder, and see the connection between florescence, phosphorescence and wavelength. Students compose hypotheses and determine experimental procedure details, as teams engineer variations on a bioplastic solid embedded with phosphorescence powder. The objective is to make a structurally sound bioplastic without reducing its glowing properties from the powder embedded within its matrix. Groups conduct qualitative and quantitative analyses of their engineered plastics, then recap and communicate their experiment conclusions in the form of a poster, slides and verbal presentation. As an extension, teams make their own testing apparatuses. As a further extension, they combine all the group results to determine which bioplastic matrix best achieves the desired properties and then “manufacture” the optimum bioplastic into glowing toy figurine end products! Many handouts, instructions, photos and rubrics are provided.

This lesson focuses on the importance of airplanes in today's society. Airplanes of all shapes and sizes are used for hundreds of different reasons, including recreation, commercial business, public transportation, and delivery of goods, among many others. From transporting people to crop-dusting, our society and our economy have come to depend on airplanes. Students will discuss their own experiences with airplanes and learn more about the role of airplanes in our world.

Waste disposal has been an ongoing problem since medieval times. Environmental engineers are employed to develop technologies to dispose of the enormous amount of trash produced in the United States. In this lesson, students will learn about the three methods of waste disposal in use by modern communities. They will also investigate how engineers design sanitary landfills to prevent leachate from polluting the underlining groundwater.

Students learn about landslides, discovering that there are different types of landslides that occur at different speeds from very slow to very quick. All landslides are the result of gravity, friction and the materials involved. Both natural and human-made factors contribute to landslides. Students learn what makes landslides dangerous and what engineers are doing to prevent and avoid landslides.

This paper discusses challenges and opportunities expected as English language learners (ELLs) engage with Next Generation Science Standards (NGSS). We subscribe to a view of language learning and proficiency that is most concerned with students’ ability to use language to function in the context of their lives both in and out of school.

Students learn and use the properties of light to solve the following challenge: "A mummified troll was discovered this summer at our school and it has generated lots of interest worldwide. The principal asked us, the technology classes, to design a security system that alerts the police if someone tries to pilfer our prized possession. How can we construct a system that allows visitors to view our artifact during the day, but invisibly protects it at night in a cost-effective way?"

Through two classroom demos, students are introduced to the basic properties of lasers through various mediums. In the Making an Electric Pickle demonstration, students see how cellular tissue is able to conduct electricity, and how this is related to various soaking solutions. In the Red/Green Lasers through Different Mediums demonstration, students see the properties of lasers, especially diffraction, in various mediums. Follow-up lecture material introduces students to the mechanisms by which lasers function and relates these functions to the properties of light. In the associated activity, student teams research specific laser types and present their findings to the class.

The learning of linear functions is pervasive in most algebra classrooms. Linear functions are vital in laying the foundation for understanding the concept of modeling. This unit gives students the opportunity to make use of linear models in order to make predictions based on real-world data, and see how engineers address incredible and important design challenges through the use of linear modeling. Student groups act as engineering teams by conducting experiments to collect data and model the relationship between the wall thickness of the latex tubes and their corresponding strength under pressure (to the point of explosion). Students learn to graph variables with linear relationships and use collected data from their designed experiment to make important decisions regarding the feasibility of hydraulic systems in hybrid vehicles and the necessary tube size to make it viable.

Students gain perspective on the intended purpose of hydraulic accumulators and why they might be the next best innovation for hybrid passenger vehicles. They learn about how hydraulic accumulators and hydraulic systems function, specifically how they conserve energy by capturing braking energy usually lost as heat. Students are given the engineering challenge to create small-scale models from which their testing results could be generalized to large-scale latex tubing for a hydraulic accumulator. After watching a video clip of an engineer talking about his lab-based model to test the feasibility of using an elastomer as an energy accumulator, they brainstorm ideas about how latex can be used in a hydraulic system and how they could test the strength of latex for use in a hydraulic accumulator. The concepts of kinetic energy and energy density are briefly discussed.

Many of today’s global challenges require tech-driven solutions — climate change, the growth of the world population, cyber security, the increasing demand for scarce resources, digitalization, the transition from fossil fuels to renewable energy. With this in mind, it is no surprise that one fourth of the CEOs of the world’s 100 largest corporations have an engineering degree.
Solving these global problems requires leaders who, in the first place, are comfortable with technology, models and quantitative analyses — Leaders who see systems instead of isolated problems. However, simply understanding technology is not enough. Successful leaders today must have both the ideas and the know-how to put these ideas into action by working collaboratively with others, winning their hearts and minds.
We need leaders who know how to seize opportunities in a networked world, and can mobilize people and other stakeholders for large-scale change. Leaders who lead fulfilling lives and who are able to move themselves and others from the ‘me’ to the ‘we’. Leaders who are long-term oriented and who deliver economic profit, while also making positive contributions to society and the environment. We call these leaders ‘sustainable leaders’.
