In this activity, students determine their own eyesight and calculate what a good average eyesight value for the class would be. Students learn about technologies to enhance eyesight and how engineers play an important role in the development of these technologies.
Students learn how 3D printing, also known as additive manufacturing, is revolutionizing the manufacturing process. First, students learn what considerations to make in the engineering design process to print an object with quality and to scale. Students learn the basic principles of how a computer-aided design (CAD) model is converted to a series of data points then turned into a program that operates the 3D printer. The activity takes students through a step-by-step process on how a computer can control a manufacturing process through defined data points. Within this activity, students also learn how to program using basic G-code to create a wireframe 3D shapes that can be read by a 3D printer or computer numerical control (CNC) machine.
In this lesson, students expand their understanding of solid waste management to include the idea of 3RC (reduce, reuse, recycle and compost). They will look at the effects of packaging decisions (reducing) and learn about engineering advancements in packaging materials and solid waste management. Also, they will observe biodegradation in a model landfill (composting).
Students will use a perceived weak material to construct something that is surprisingly strong.
Students can experiment with different shapes and configurations to see what holds the most weight.
The cube size is defined, what each student places within each 4x4 square, is up to them.
This eBook was written as the sequel to the eBook titled DC Circuits, which was written in 2016 by Chad Davis.
This eBook covers Alternating Current (AC) circuit theory as well us a brief introduction of electronics. It is
broken up into seven modules. Module 1 covers the basic theory of AC signals. Since only DC sources are used in
the first eBook, details of AC signals such as sinusoidal waveforms (or sine waves), square waves, and triangle
waves are provided. Module 2, titled AC Circuits Math Background, covers the mathematics background needed
for solving AC circuit problems. The background material in Modules 1 and 2 are combined in Module 3 to solve
circuits with AC sources that include resistors, inductors, and capacitors (RLC circuits).
This animated essay from the American Experience Web site explains the difference between alternating and direct electric current and offers in-depth explanations about the role played by a battery, light bulb, wire, and generator. Grades 6-12. ***Access to Teacher's Domain content now requires free login to PBS Learning Media.
In this professional development session, we will develop a shared understanding of how formative assessment works and different approaches that have been developed. The material for this resource come from a series of PD sessions on formative assessment developed by the ACESSE team: Philip Bell, Shelley Stromholt, Bill Penuel, Katie Van Horne, Tiffany Neill, and Sam Shaw.We will be updating this Facilitator's Guide for ACESSE Resource A with the most up-to-date information about this resource over time.

The NRC Framework for K-12 Science Education and the resulting Next Generation Science Standards focus on an integrated three-dimensional view of science learning in which students develop understanding of core ideas of science and crosscutting concepts in the context of engaging in science and engineering practices.How is assessing three-dimensional science learning different than how we have thought of science learning in the past? How can we design assessment tasks that elicit student’s current understanding of specific aspects of the disciplinary core ideas, science and engineering practices, and crosscutting concepts in order to shape future instruction? In this workshop, participants will learn how to interpret and design cognitive formative assessment to fit a three-dimensional view of learning.This resource originates from a series of PD sessions on 3D formative assessment developed and provided by Katie Van Horne, Shelley Stromholt, Bill Penuel, and Philip Bell. It has been improved through a collaboration in the ACESSE project with science education experts from 13 states.

Abstract: This session provides a step-by-step process to support participants as they design a 3D assessment task for the science classroom. Along the way, they learn how to define 3D learning performances for specific lessons—and how to use a range of tools to support their assessment design work. A key goal of the session activity is to improve the connection of intended learning goals to assessment practices. Participants build their 3D assessment design capacity by designing and workshopping tasks—before piloting them in their classrooms. The approaches learned in this workshop can be used with any curricula, at any grade level, and across all subjects of science.
Overview: In this workshop, we will build our capacity to identify the range of intellectual resources students use as they make sense of phenomena. We will first explore how equity and justice relate to culture-based approaches to pedagogy—and then focus on how to identify and leverage the resources students use in moments of sensemaking. This resource can also be used by individuals wanting to learn how equity involves promoting the rightful presence of all students across scales of justice, desettling inequities, and supporting expansive learning pathways. This workshop provides participants with an opportunity to explore important theoretical ideas by exploring examples of how learners engage in diverse sense-making. Participants will learn about some of the challenges that less expansive learning environments can cause for learners from non-dominant communities. This resource is estimated to take between 161-268 minutes (2 ⅔ - 4 ¾ hours), depending on the choices of the facilitator in scenario selection.
Student groups create working radios by soldering circuit components supplied from AM radio kits. By carrying out this activity in conjunction with its associated lesson concerning circuits and how AM radios work, students are able to identify each circuit component they are soldering, as well as how their placement causes the radio to work. Besides reinforcing lesson concepts, students also learn how to solder, which is an activity that many engineers perform regularly giving students a chance to be able to engage in a real-life engineering activity.
In the last two decades, research in various aspects of mobile ad-hoc networks, MANETs, has been very active, motivated mainly by military, disaster relief and law enforcement scenarios. More recently, location information has become increasingly available; partially prompted by the emerging trend to incorporate location or position sensing into personal handheld devices. An evolutionary natural step is to adopt such position-based operation in MANETs. This results in what we call position-based MANETs. In such settings, devices are equipped with position-sensing capabilities and rely on position information in their operation. The main distinguishing feature of the envisaged position-based MANET environment is the communication paradigm based not on permanent or semi-permanent identities, addresses or pseudonyms, but on instantaneous node locations or positions. In some application settings, such as: military, law enforcement and search-and-rescue, node identities are not nearly as important as node positions. Such settings have certain characteristics in common. First, node position is very important: knowledge of the physical, as opposed to logical or relative topology, makes it possible to avoid wasteful communication and focus on nodes located within a speciﬁc area. Thus, the emphasis is not on the longterm node identity, but rather on current node position. Second, critical environments face security and privacy attacks. Security attacks aim to distribute false location and network ing control information, e.g., routing control messages, or impede the propagation of genuine information. The goal of privacy attacks is to track nodes as they move. Third, when the operating environment is hostile, as is the case in military and law enforcement settings, node identities must not be revealed. We use the term hostile to mean that communication is being monitored by adversarial entities that are not part of the MANET. The need to hide node identities becomes more pressing if we further assume that MANET nodes do not trust each other, due to a suspicious environment where nodes can be compromised. In such an environment, it is natural for node movements to be obscured, such that tracking a given node is impossible or, at least, very diﬃcult. While we do not claim that such suspicious and hostile location-based MANET environments are commonplace, they do occur and require high security and privacy guarantees. While doing all these;there is a challenge for nodes to maintain anonymity protection from outside observers or malicious attackers. Full anonymity protection can be achieved only when ;sources,destinations and routes all are protected. In this work, to oﬀer better anonymity protection, we propose an Anonymous Position-based Security Aware Routing Protocol (APSAR). Experimental results exhibit consistency with the theoretical analysis, and show that APSAR achieves better route anonymity protection compared to other anonymous routing protocols. Also, APSAR achieves comparable routing eﬃciency to the GPSR geographical routing protocol. The work in this thesis addresses a number of security and privacy issues arising in position-based MANETs. models. We address the problem of position based security aware routing in consideration with better anonymity protection .
