This video segment adapted from NOVA features a variety of scientific perspectives on the age old question, "Are we alone in the universe?" Animations make vivid the improbability that we could intercept a radio wave signaling extra terrestrial intelligence.

Why does a balloon stick to your sweater? Rub a balloon on a sweater, then let go of the balloon and it flies over and sticks to the sweater. View the charges in the sweater, balloons, and the wall.

Use the GoPro to teach track and field participants how to be successful competitors.

Motion is all around us, the universe is full of moving matter and this motion is surprisingly predictable. The field of science and engineering that studies time-dependent motion in the presence of forces is called Dynamics. In this book we will introduce the core concepts in dynamics and provide a comprehensive toolset to predict and analyse planar 2D motion of point masses and rigid bodies. The material includes kinematic analysis, Newton’s laws, Euler’s laws, the equations of motion, work, energy, impulse and momentum. Vector-based methods are discussed for systematically solving essentially any problem in 2D dynamics. The book provides a bachelor level introduction for any science and engineering student that can serve as a basis for more advanced courses in dynamics.

This book provides practical advice and guidance to pre-service teachers and teachers who are teaching outdoor education in Victoria. It has been written as a handbook to support the development and delivery of school programs that align to both the Victorian Curriculum F-10 and those who deliver VCE Outdoor and Environmental Studies.

This exercise is intended to help link the observations of water and sediment
motion that student made in the laboratory flume with the theory discussed in
lecture. Students use the measurements made to ask some basic questions about what happened in the flume as the discharge was varied by a factor of two.

This book covers the material normally presented in a two-term course on numerical analysis, starting with the basic concept and ending with topics that are more appropriate for a course in numerical analysis for differential equations: numerical solution of systems of linear and nonlinear equations, polynomial interpolation, numerical approximation of functions, numerical computation of eigenvalues, numerical derivation and integration, numerical solution of ordinary and partial differential equations.

With a focus on algorithms, it can be used as an introduction to numerical analysis for engineering and applied science students. With a focus on theory, it can be used as an introduction to numerical analysis for students in mathematics or physics. Most of the numerical methods presented in this book are accompanied by a MATLAB code.

This lesson seeks to engage in discussions about relationships, emotional, and physical relatedness, and whether biological connections are the only connections that make a family. Understanding how society has traditionally defined family may not be the way we define it – and that’s okay. In this lesson, participants will expand their knowledge of a more involved family tree. When it comes to describing family/kinship, does a biological connection hold more weight, or do emotional connections that develop over time hold equal importance? Understanding relationships, values, and what resonates as important is helpful in practicing and engaging critical thinking skills.

To be able to understand the importance of the environment for our health, we need to know a little about the interdependence between environment and humankind. This unit will look at interactions between plants, animals and the physical and chemical environment, as well as considering ways in which humans have altered, and are altering this environment. These changes have health implications that are not always immediately obvious. Frequently, we initiate changes that are going to have their effects some time in the future, and we will be looking at the legacies that we leave to future generations. We move on to consider our own demise, and ask what exactly it is that we think we will be leaving for those who follow.

This course presents a top-down approach to communications system design. The course will cover communication theory, algorithms and implementation architectures for essential blocks in modern physical-layer communication systems (coders and decoders, filters, multi-tone modulation, synchronization sub-systems). The course is hands-on, with a project component serving as a vehicle for study of different communication techniques, architectures and implementations. This year, the project is focused on WLAN transceivers. At the end of the course, students will have gone through the complete WLAN System-On-a-Chip design process, from communication theory, through algorithm and architecture all the way to the synthesized standard-cell RTL chip representation.

(This case study was added to OER Commons as one of a batch of over 700. It has relevant information which may include medical imagery, lab results, and history where relevant. A link to the final diagnosis can be found at the end of the case study for review. The first paragraph of the case study -- typically, but not always the clinical presentation -- is provided below.)

The patient is a 57-year old female with a past medical history of thyroidectomy, hysterectomy, and papillary fibroepithelial hyperplasia of the buccal mucosa. She presented with a three-month history of progressive vertigo, ataxia, and posterior headache. Physical examination revealed lateral nystagmus, dysdiadochokinesis and ataxia.

Students are often confused by the concepts of stable isotope signatures and conventional notation. This activity is designed to introduce students to the del notation (isotopic signature), fractionation, and end member mixing of stable isotopes using familiar objects disguised as isotopes. The activity does not explain the physical manifestation of why isotopic fractionation occurs, but does explain the concepts that one easily observes when interpreting stable isotope data sets.

 This online material offers to student a pleasant and fun environment to achieve the development of learning. Online learning can replace a good portion of in-person class time, thus reducing the need for on-campus meetings. In this time, students will have the chance to interact with tasks related to sports. Basically, those materials are made for students of physical education, health and sports, who are attending the first level of English. Students will encounter reading activities, matches, wordsearch puzzle, listening exercises, speaking tasks and so on. In one way or another, learner will be in contact all the time with the sports issue. 

A database of and access to journal articles and book chapters found useful by college and university science students; built from student work at Grinnell College, Grinnell, IA, USA. Used in science courses (especially Biology and Psychology courses) at Grinnell College.

This video addresses the importance of efficiency in providing power to an increasingly large global population.

Students are presented with a challenge question that they must answer with scientific and mathematical reasoning. The challenge question is: "You have a large rock on a boat that is floating in a pond. You throw the rock overboard and it sinks to the bottom of the pond. Does the water level in the pond rise, drop or remain the same?" Students observe Archimedes' principle in action in this model recreation of the challenge question when a toy boat is placed in a container of water and a rock is placed on the floating boat. Students use terminology learned in the classroom as well as critical thinking skills to derive equations needed to answer this question.

This is a lesson plan for disc golf. It discusses the rules, techniques , and tactical aspects involved in disc golf.

Students work to increase the intensity of a light bulb by testing batteries in series and parallel circuits. They learn about Ohm's law, power, parallel and series circuits, and ways to measure voltage and current.
