Social media plays a big role in most teens' lives, and research shows that it causes intense feelings -- both positive and negative. But not all media use is the same. There are many benefits that come with both active and passive media use. For better social and emotional well-being, encourage students to become creators of digital media, not just consumers.

Students learn how the innovative engineering of photovoltaics enables us to transform the sun’s energy into usable power—electricity—through the use of photovoltaic cells. Watching a short video clip from “The Martian” movie shows the importance of photovoltaics in powering space exploration at extreme distances from the Earth. Then students learn that the photovoltaic technologies designed to excel in the harsh environment of space have the potential to be just as beneficial on Earth—providing electricity-generating systems based on renewable energy sources is important for our electricity-gobbling society. Two student journaling sheets assist with vocabulary and concepts.

Sal solves a linear system with 3 variables by representing it with an augmented matrix and bringing the matrix to reduced row-echelon form. Gaussian Elimination is the method, reduced row echelon is just the final result.

The SpinTX video archive provides a convenient web interface to search hundreds of short video clips from the Spanish in Texas Corpus. The collection includes hundreds of video clips culled from interviews of native and heritage speakers of Spanish living in Texas. Each video is accompanied by synchronized closed captions and a transcript that has been annotated with thematic, grammatical, functional and metalinguistic information. All materials available on the site can be freely used, copied, and distributed under a Creative Commons license.

Students are introduced to the technology of flexible circuits, some applications and the photolithography fabrication process. They are challenged to determine if the fabrication process results in a change in the circuit dimensions since, as circuits get smaller and smaller (nano-circuits), this could become very problematic. The lesson prepares students to conduct the associated activity in which they perform statistical analysis (using Excel® and GeoGebra) to determine if the circuit dimension sizes before and after fabrication are in fact statistically different. A PowerPoint® presentation and post-quiz are provided. This lesson and its associated activity are suitable for use during the last six weeks of the AP Statistics course; see the topics and timing note for details.
Street lights of the same type will look brighter when they are …
Street lights of the same type will look brighter when they are close to you, and less bright when they are farther away. The same applies to astronomical objects: a given star will look brighter to a nearby observer than to an observer far away. In both cases, the difference in brightness can be used to deduce the relative distances of suitable objects. Standard candles, objects of constant intrinsic brightness or whose intrinsic brightness can be determined by careful measurements, are a key tool for astronomical distance determination. In this exploration, you will explore standard candles (and also effects that complicate distance measurements) in a simple everyday setting, namely that of street lights, using a digital camera and freely available software.

At this stage of the "Lost in the Amazon" (hypothetical) adventure, students determine what supplies they will take with them to survive their trip through the Amazon. They use estimation and basic math skills to determine how much they can carry and what they can use to survive in the jungle environment as they travel on to their destination.

Explore what it means for a mathematical statement to be balanced or unbalanced by interacting with integers and variables on a balance. Find multiple ways to balance x and y to build a system of equations.

Roller coasters projects are frequently used in middle and high school physics classes to illustrate the principle of conservation of mechanical energy. Potential energy transforms to kinetic energy and vice versa, with gravity being the driving force during the entire process. Even though friction force is mentioned, it is rarely considered in the velocity calculations along the coasters’ paths. In this high school lesson, the friction force is considered in the process. Using basic calculus and the work-energy theorem for non-conservative forces, the friction along a curved path is quantified, and the cart’s velocity along this path is predicted. This activity and its associated lesson are designed for AP Calculus. Practice problems/answers, a PowerPoint® presentation and student notes are provided.

Students learn about water quality testing and basic water treatment processes and technology options. Biological, physical and chemical treatment processes are addressed, as well as physical and biological water quality testing, including testing for bacteria such as E. coli.

Staying safe online is a lot like staying safe in the real world. By helping a Digital Citizen sign up for a new app, students learn about the kinds of information they should keep to themselves when they use the internet -- just as they would with a stranger in person.

With mobile phone alerts, social media updates, and 24/7 news cycles, it's hard to escape the daily flood of breaking news. But do kids really understand what they're seeing when stories first break? Help students analyze breaking news with a critical eye for false or incomplete information, and discuss the downsides of our "always-on" news media culture.

From selfies to social media, many of us create unique online identities for ourselves, and our students are no different. But do kids always understand how others might perceive what they post? Help your students think critically about the online identities they're creating.

Students are introduced to an engineering challenge in which they are given a job assignment to separate three types of apples. However, they are unable to see the color differences between the apples, and as a result, they must think as engineers to design devices that can be used to help them distinguish the apples from one another. Solving the challenge depends on an understanding of wave properties and the biology of sight. After being introduced to the challenge, students form ideas and brainstorm about what background knowledge is required to solve the challenge. A class discussion produces student ideas that can be grouped into broad subject categories: waves and wave properties, light and the electromagnetic spectrum, and the structure of the eye.

This resource contains links to two sets of slides and a blank pdf weekly schedule.The first set of slides focusses on getting students to reflect on how they use their time and what might be expected of them at the college level.The second set of slides gets into specific strategies for how to manage time. It is helpful to have students track their time while working through these presentations or in between the first and the second so that they can better relate to what they are reading to their own experience.
