The purpose of this task is to strengthen students' understanding of area. It could be assigned in class to individuals or small groups or given as a homework exercise to generate interesting discussions the following day. The relatively high levels of complexity and technical demand enhance its instructional value.

The Eight Components of College and Career Readiness Counseling provide a systemic approach for school counselors to implement, across grades K–12 — elementary through high school and beyond, to ensure equity both in process and results.

The internet is inconceivably large. In fact, it’s essentially endless! Sometimes it’s easy to find the information you need, but often trying to find something specific can feel like looking for a needle in a haystack. This blog post outlines eight tips to help you improve your search results and zero in on what you’re looking for more quickly. It can be used with lateral reading or when teaching research.

Eileen Walbert was among the Concerned White Citizens of Alabama who took a stand for civil rights, as she describes in this oral history from the Birmingham Civil Rights Institute.

This course covers the role of physics and physicists during the 20th century, focusing on Einstein, Oppenheimer, and Feynman. Beyond just covering the scientific developments, institutional, cultural, and political contexts will also be examined.

For the first time ever, Rainer Blatt was able to transfer the state of one atom to another. Although the process is called 'teleportation,' no matter is transported from one spot to another. Instead, information leaps the gap.

According to a theory first put forward by Albert Einstein, a large body of mass cures space and the light that traverses it. Clusters of galaxies create what are known as gravitational lenses.

Though he's just 32 years old, Immanuel Bloch is already a professor of physics at the University of Mainz. He's an expert on a state of matter that was predicted by Albert Einstein - Bose-Einstein condensation.

When an atom in a radioactive element decays, part of the matter that makes up its nucleus is transformed into energy. This is part of the proof that backs up Einstein's realization that mass and energy are two sides of the same coin.

What a pain: the cell phone has to be charged every few days. But in future that could be rendered obsolete by a portable charging unit in a jacket. It consists of wafer-thin organic solar cells. Like conventional silicon cells, the organic solar cells convert light energy into electrical current. The principle behind it is the photoelectric effect. Albert Einstein received the Nobel Prize in 1921 for his explanation of this phenomenon.

Molecules in gas and fluids tend to behave in unordered and random ways. This phenomenon, first identified by the Scottish botanist Robert Brown and therefore named Brownian Motion, was also of great interest to Albert Einstein. In 1905, he published his studies on Brownian Motion. Today, his findings can help researchers solve many of the problems linked to the movement of particles.

Time is relative - in the field of satellite navigation, Einstein's theory has practical applications. In space, clocks tick differently than they do on Earth. But the accuracy of satellite navigation systems is dependent on how precisely the atomic clocks on board can measure time.

For much of his life, Albert Einstein sought a formula that would describe and encompass all four fundamental forces. He failed to find a unifying theory. The tunnel in Geneva is huge - and it runs in a circle that's 27 kilometers long. Thousands of scientists all over the world are waiting with bated breath for experiments to begin in the Large Hadron Collider.

At the root of Albert Einstein's Special Theory of Relativity is the assumption that the speed of light never changes. Einstein said that the speed of light is a universal constant, one that always remains the same no matter where you are. Is that really the case? European researchers now want to conduct an experiment in space to find out.
The speed of light also standardizes the exact length of a meter. …
The speed of light also standardizes the exact length of a meter. That's important for large-scale surveys like those slated to be carried out by the radar satellite TerraSAR-X. The radar satellite will begin surveying Earth's surface with an accuracy never before seen in civilian applications.

Laboratories all over the world have been taking part in a competition to create shorter and shorter flashes of laser light. Now physicist Ferenc Krausz has broken a new barrier. He's first to produce an attosecond pulse. An attosecond is an unimaginable 0.000000000000000001 of a second long.

This video, adapted from NASA, presents rare experimental evidence from the Fermi Gamma-ray Space Telescope supporting Einstein's prediction that space-time is smooth.

In this lesson, students explore ekphrasis--writing inspired by art. Students find pieces of art that inspire them and compose a booklet of poems about the pieces they have chosen.

"El Alfabeto" is an interactive software program that presents the letters of the Spanish alphabet that are different from the English letters. It includes the following letters or letter groups: a, d, e, g, h, i, j, ll, ñ, o, q, rr, u, v, and z. The viewer will see examples of words that use those letters, and can click a button to hear those words pronounced. This program runs on Windows computers only.
