King Leads the March on Washington
the March on Washington (3:10) On August 28, 1963, a quarter million people gather to support civil rights, and share Dr. King's "dream" of equality. This video is highlighted by King's "I have a dream speech" and the reaction to it. The efforts of the federal government to enforce civil rights is explained as well as how the March was organized and where.

Backstage at The New Theatre Ep 6: The Lonesome West
This week we're on the set of the anarchic and hilarious The Lonesome West by Martin McDonagh. The New Theatre is the only student-run theatre company in the UK. www.newtheatre.org.uk
Introducción al Derecho (2011)
Esta asignatura se configura dentro del Primer Curso del Grado en Relaciones Laborales de la Universidad de Cantabria, teniendo como finalidad, la asimilación de conceptos jurídicos básicos. A tal efecto, se efectúa una aproximación a la idea de Derecho; se estudia la norma jurídica; las fuentes del Derecho; el Estado y sus instituciones básicas; y los derechos fundamentales.
Constructing Sonoran Desert Food Chains and Food Webs
Is the food chain shown above accurate? Does the first link depict a producer, the second link a herbivore, and the third link an omnivore / carnivore? Students must correctly determine whether a species is a producer or consumer, and what type of consumer; herbivore, omnivore, or carnivore. Students will be provided with a list of Sonoran Desert species and asked to construct, within their groups, several food chains. These food chains will then be used to construct a food web. In order to comp
Fundamentals of Populations and Population Growth
This activity reinforces the concepts covered in the lecture presented during LESSON 3 of this unit. It takes the student through the definition of a population. Graphing skills are tested and the difference between the independent and dependent variables is explained. The S-shaped and Boom and Bust growth rate curves are next compared and contrasted. The activity then asks the student to analyze a data table and to plot its points. Students gain personal application of the lesson material. And
Adaptations for Bird Flight – Inspiration for Aeronautical Engineering
This activity first asks the students to study the patterns of bird flight and understand that four main forces affect the flight abilities of a bird. They will study the shape, feather structure, and resulting differences in the pattern of flight. They will then look at several articles that feature newly designed planes and the birds that they are modeled after. The final component of this activity is to watch the Nature documentary, “Raptor Force” which chronicles the flight patterns of b
The Great Pacific Garbage Patch
The Great Pacific Garbage Patch (GPGP) is an interesting and somewhat publicized environmental problem. A swirling soup of trash up to 10 meters deep and just below the surface of the waters is composed mainly of non-degradable plastics. These plastic materials trap aquatic life and poison them either by physical blockage or as carriers of toxic pollutants. The problem relates to materials science and the advent of plastics in modern life, a case of technology having unintended consequences. Stu
Sum It Up: An Introduction to Static Equilibrium
Students are introduced to static equilibrium by learning how forces and torques are balanced in a well-designed engineering structure. A tower crane is presented as a simplified two-dimensional case. Using Popsicle sticks and hot glue, student teams design, build and test a simple tower crane model according to these principles, ending with a team competition.
Pointing at Maximum Power for PV
Student teams measure voltage and current in order to determine the power output of a photovoltaic (PV) panel. They vary the resistance in a simple circuit connected to the panel to demonstrate the effects on voltage, current, and power output. After collecting data, they calculate power for each resistance setting, creating a graph of current vs. voltage, and indentifying the maximum power point.
Energy Forms, States and Conversions
The students participate in many demonstrations during the first day of this lesson to learn basic concepts related to the forms and states of energy. This knowledge is then applied the second day as they assess various everyday objects to determine what forms of energy are transformed to accomplish the object’s intended task. The students use block diagrams to illustrate the form and state of energy flowing into and out of the process.
Students learn some basic facts about asteroids in our solar system, mainly about the size of asteroids and how that relates to the potential danger of an asteroid colliding with the Earth. Students are briefly introduced to the destruction that would ensue should a large asteroid hit, as it did 65 million years ago.
Student are introduced to rivers, and to the components of the water cycle. They think about the effects of communities, sidewalks and roads on the natural flow of rainwater. Students also learn about the role of engineering in community planning and protecting our natural resources.
Students reinforce their understanding of rocks, the rock cycle, and geotechnical engineering by playing a trivia game. They work in groups to prepare Jeopardy-type trivia questions (answers) and compete against each other to demonstrate their knowledge of rocks and engineering.
Students learn the basics about soil, including its formation, characteristics and importance. They are also introduced to soil profiles and how engineers conduct site investigations to learn about soil quality for development, contamination transport, and assessing the general environmental health of an area.
Hot Problem Solving
Student teams follow the steps of the engineering design process to meet the challenge of getting their entire class from one location on the playground to the sidewalk without touching the ground between. The class develops a well thought-out plan while following the steps of the engineering design process. Then, they test their solution by going outside and trying it out. Through the post-activity assessment, they compare their problem-solving experience to real life engineering challenges, su
Touch and Discover
Students work in pairs or small groups to identify and categorize various objects. One student is blindfolded and the other student chooses five objects for their partner to identify. The blindfolded student has to describe and try to identify the object based solely on touch. Both students then record their data, describing the objects first as human-made or natural, then living or non-living, and finally physical characteristics.
Glue Sticks Bend & Twist
Students use hot glue gun sticks to learn about the forces of tension, compression and torsion.
Energetic Musical Instruments
Students will learn to apply the principles and concepts associated with energy and the transfer of energy in an engineering context through the designing and making of a musical instrument. The students must choose from a variety of supplies presented to them to make an instrument capable of producing three different tones. After the accomplishment of the design, students must explain the energy transfer mechanism in sufficient detail and describe how they could make their instruments better.
