This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:

"Economists have long acknowledged that physical attractiveness affects wages. Highly attractive men and women generally earn more than ordinary people doing comparable work. But it’s not clear _why_ this linkage exists. To answer this question, two scientists recently reported on a study designed to uncover the root cause of this so-called beauty premium. Their results imply that physically attractive people make more money _not_ because they’re beautiful, but rather because they’re healthier, more intelligent, and have more pleasant personalities. Their study tracked the careers and physical attractiveness of over 15,000 people for more than ten years. Participants were interviewed starting around age 16 and again at ages 17, 22, and 29. In each interview, they shared their gross personal earnings over the previous year and described their current occupation and health status. They also completed personality assessments and IQ tests..."

The rest of the transcript, along with a link to the research itself, is available on the resource itself.

Using the same method for measuring friction that was used in the previous lesson (Discovering Friction), students design and conduct an experiment to determine if weight added incrementally to an object affects the amount of friction encountered when it slides across a flat surface. After graphing the data from their experiments, students can calculate the coefficients of friction between the object and the surface it moved upon, for both static and kinetic friction.

Two dramatically different philosophical approaches to classical mechanics were proposed during the 17th – 18th centuries. Newton developed his vectorial formulation that uses time-dependent differential equations of motion to relate vector observables like force and rate of change of momentum. Euler, Lagrange, Hamilton, and Jacobi, developed powerful alternative variational formulations based on the assumption that nature follows the principle of least action. These variational formulations now play a pivotal role in science and engineering.

This book introduces variational principles and their application to classical mechanics. The relative merits of the intuitive Newtonian vectorial formulation, and the more powerful variational formulations are compared. Applications to a wide variety of topics illustrate the intellectual beauty, remarkable power, and broad scope provided by use of variational principles in physics.

In this lesson designed to enhance literacy skills, students explore brain injuries called concussions: what they are, how they occur, the challenges in diagnosing them, and ways to protect yourself from them.

In this lesson, students learn about the water cycle and how climate change impacts its patterns.

Step 1 - Inquire: Students contemplate their relationship with water and observe a demonstration to determine if shifting climates may affect the water cycle.

Step 2 - Investigate: Students explore an interactive diagram about the water cycle.

Step 3 - Inspire: Students watch a video and complete a series of questions in their student journals.

In this unit, students wonder about the physical drivers of ocean movement, explore density differences, and take a look at some tiny creatures who struggle to keep their place in the water column in the midst of all that ocean motion.
Each unit of the Explore the Salish Sea curriculum contains a detailed unit plan, a slideshow, student journal, and assessments. All elements are adaptable and can be tailored to your local community.

The purpose of the resource is to investigate changes in the major land cover types of Study Sites by examining Landsat satellite images acquired years apart.

The lessons in this unit were developed by teachers at Souhegan High School for junior/senior level Physics classes, to be taught during the first trimester of the 2016-17 school year. This unit culminates with small groups of students presenting their plans for the ideal power grid for the state of New Hampshire. While the anchor text and performance assessment may be specific to New Hampshire, texts specific to other regions are likely accessible through state universities, government websites and/or local publications, making this unit highly adaptable.

Explore the physics and material science of making stone tools. Educator Nate Salzman walks us through the surprisingly complex science of flintknapping, or the process of turning stone into blades, arrowheads, spear points, axes, jewelry and more. Making tools from stone may be thousands of years old, but required people to think about the properties of the material they were using and the physics of striking the stone to shape it just right.

Consider using this resource to support classroom learning about the relationship between microscopic and macroscopic properties and how forces are transmitted. Animations derived from this video have been published separately as "Animations - The Science of Knapping."

 This lesson provides a brief overview of sexual and reproductive anatomy, and explains how to complete self exams of breasts and testicles. It reviews the basics of reproduction, and introduces the many ways of becoming parents. The final activity asks students to consider the many responsibilities of becoming a parent.

Effective field theory is a fundamental framework to describe physical systems with quantum field theory. Part I of this course covers common tools used in effective theories. Part II is an in depth study of the Soft-Collinear Effective Theory (SCET), an effective theory for hard interactions in collider physics.

By the end of this section, you will be able to:Define and distinguish between the three domains of development: physical, cognitive and psychosocialDiscuss the normative approach to developmentUnderstand the three major issues in development: continuity and discontinuity, one common course of development or many unique courses of development, and nature versus nurture

A unit on wave phenomena, and its applications to detecting and evaluating extrasolar planets, and lighting and sound design in theatrical productions. The unit is designed for a high school physics class, but could be modified for physical science, astronomy, technical theater, or the middle school level.

This lesson will help students become more proficient at creating a weld bead in the flat position.
