Archimedes' Puzzle
Read the Fine Print
Rating
0.0 stars

In this math activity, learners explore the history of the Stomachion (an ancient tangram-type puzzle), use the pieces to create other figures, learn about symmetry and transformations, and investigate the areas of the pieces. The Stomachion, believed to have been created by Archimedes, consists of 14 pieces cut from a square, which can be rearranged to form other interesting shapes.

Beating the Motion Sensor

Educational Use
Rating
0.0 stars

Lighting is responsible for nearly one-third of the electricity use in buildings. One of the best ways to conserve energy is to make sure the lights are turned off when no one is in a room. This process can be automated using motion sensors. In this activity, students explore material properties as they relate to motion detection, and use that knowledge to make design judgments about what types of motion detectors to use in specific applications.

CESA 7 ACP Artifact Reflections
Conditional Remix & Share Permitted
CC BY-NC
Rating
0.0 stars

ACP Programs typically have students gather artifacts throughout high school to represent their learning and growth.  Many times these artifacts are gathered in a portfolio format.  This particular reflection on student learning is completed by having students complete an oral reflection about a particular artifact of their choice. The rubric is provided for the presentation with the intent that the student is able to link their experiences in and outside of the classroom to soft skills they will need in their future as a student and employee.  This type of reflection can reinforce current soft skills emphasized in your district and help student make the connection between school and career.

Rating
0.0 stars

A comprehensive ACP Program has students create and revise Individualized Learning Plans annually.  This lesson provides examples of grade level ILP forms that can be modified by school districts to use with students prior to course registration on a yearly basis.  The ILP's can also be shared with parents during Parent Teacher Conferencing or ACP conferencing.  Students will reflect on their strengths, areas to improve, standardized test results, Career Clusters of interest, post-secondary planning, course selection and co-curricular involvement.

Rating
0.0 stars

Personality Assessments have been used for decades and can be a valuable tool in Academic and Career Planning.  Humanmetrics.com http://www.humanmetrics.com/cgi-win/jtypes2.asp provides a free personality assessment and results analysis.  Students should not merely take the assessment but should delve into their results by looking at the personality types strengths and weaknesses, potential careers and how businesses use personality assessments.  Results should be viewed with a critical lens and should help students have a better understanding of the importance of self-reflection as part of their ACP process.

Concentrated Solar Power
Read the Fine Print
Educational Use
Rating
0.0 stars

Students learn how the total solar irradiance hitting a photovoltaic (PV) panel can be increased through the use of a concentrating device, such as a reflector or lens. This is the final lesson in the Photovoltaic Efficiency unit and is intended to accompany a fun design project (see the associated Concentrating on the Sun with PVs activity) to wrap up the unit. However, it can be completed independently of the other unit lessons and activities.

Educational Use
Rating
0.0 stars

Students design, build and test reflectors to measure the effect of solar reflectance on the efficiency of solar PV panels. They use a small PV panel, a multimeter, cardboard and foil to build and test their reflectors in preparation for a class competition. Then they graph and discuss their results with the class. Complete this activity as part of the Photovoltaic Efficiency unit and in conjunction with the Concentrated Solar Power lesson.

Determining Concentration

Rating
0.0 stars

Students quantify the percent of light reflected from solutions containing varying concentrations of red dye using LEGO© MINDSTORMS© NXT bricks and light sensors. They begin by analyzing a set of standard solutions with known concentrations of food coloring, and plot data to graphically determine the relationship between percent reflected light and dye concentration. Then they identify dye concentrations for two unknown solution samples based on how much light they reflect. Students gain an understanding of light scattering applications and how to determine properties of unknown samples based on a set of standard samples.

Discovery Through Juxtaposition
Read the Fine Print
Rating
0.0 stars

Problem solving is often guided by disciplinary frames of reference, which can restrict our ability to see other possibilities. This exercise uses object-based learning to underscore the idea that there is more than one way of analyzing and knowing the world, and that through multiple ways of knowing, we develop more complex understandings and new solutions. Through the process of critique, an essential part of visual-arts pedagogy, students practice analyzing and reflecting both individually and in groups.

Educational Use
Rating
0.0 stars

In a hands-on way, students explore light's properties of absorption, reflection, transmission and refraction through various experimental stations within the classroom. To understand absorption, reflection and transmission, they shine flashlights on a number of preselected objects. To understand refraction, students create indoor rainbows. An understanding of the fundamental properties of light is essential to designing an invisible laser security system.

Geometry Tools: Angles & Reflections
Read the Fine Print
Educational Use
Rating
0.0 stars

Students learn about common geometry tools and then learn to use protractors (and Miras, if available) to create and measure angles and reflections. The lesson begins with a recap of the history and modern-day use of protractors, compasses and mirrors. After seeing some class practice problems and completing a set of worksheet-prompted problems, students share their methods and work. Through the lesson, students gain an awareness of the pervasive use of angles, and these tools, for design purposes related to engineering and everyday uses. This lesson prepares students to conduct the associated activity in which they “solve the holes” for hole-in-one multiple-banked angle solutions, make their own one-hole mini-golf courses with their own geometry-based problems and solutions, and then compare their “on paper” solutions to real-world results.

Laser Light Properties: Protecting the Mummified Troll!

Rating
0.0 stars

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?"
