This art history video discussion examines Edgar Degas' "The Bellelli Family", 1858-67, oil on canvas (Musee d'Orsay, Paris). Degas was in his mid-twenties when he painted this canvas. It depicts from left to right, the ten-year-old Giovanna, her mother, the artist's paternal aunt Laura, her younger daughter, Giula age 7, and the Baron Gennaro Bellelli. Preperatory sketches for the painting may have been made in Florence where the family was living, the Baron had been exiled from Naples. The picture may have been completed in Paris.

Today we're going to talk about degrees of freedom - which are the number of independent pieces of information that make up our models. More degrees of freedom typically mean more concrete results. But something that is statistically significant isn't always practically significant. And to measure that, we'll introduce another new concept - effect size.

This art history video discussion examines Eugene Delacroix's "Scene of the Massacre at Chios": Greek families awaiting death or slavery, 1824 Salon, oil on canvas, 164" x 139" (419 cm x 354 cm) (Musee du Louvre, Paris) .

This art history video discussion examines Eugene Delacroix's "The Death of Sardanapalus", 1827, oil on canvas (Musee du Louvre, Paris).

Students thoroughly explore identifying synonyms and adjectives before using them to add variety and interest to their own writing.

The primary purpose of this task is to illustrate certain aspects of the mathematics described in the A.SSE.1. The task has students look for structure in algebraic expressions related to a context, and asks them to relate that structure to the context. In particular, it is worth emphasizing that the task requires no algebraic manipulation from the students.

Psychologist Philip Zimbardo asks, "Why are boys struggling?" He shares some stats (lower graduation rates, greater worries about intimacy and relationships) and suggests a few reasons -- and challenges the TED community to think about solutions. A quiz, thought provoking question, and links for further study are provided to create a lesson around the 5-minute video. Educators may use the platform to easily "Flip" or create their own lesson for use with their students of any age or level.

In which John Green teaches you about the end of World History, and the end of the world as we know it, kind of. For the last hundred years or so, it seemed that one important ingredient for running an economically successful country was a western-style democratic government. All evidence pointed to the idea that capitalist representative democracies made for the best economic outcomes. It turns out that isn't the only way to succeed. In the last 40 years or so, authoritarian capitalism as it's practiced in places like China and Singapore has been working really, really well. John is going to look at these systems and talk about why they work, and he's even going to make a few predictions about the future. Also, thanks for watching this series. It has been amazingly fun to create, and we appreciate all of you.

Sociology often looks at different age cohorts. A cohort is simply a group of people, but here we're looking specifically at different age groups or generations, because these people all lived through the same certain events through a certain time that affected their lives similarly.

Students demonstrate comprehension by responding to open-ended questions based on the Newbery Honor book "Mr. Popper's Penguins", and then draw from the text and their personal experiences to create journals.

Students use the elements of persuasion for a specific audience to demonstrate their understanding of Richard WrightŐs accessible and engaging coming-of-age novel, "Rite of Passage.

In this first part of a two-part lab activity, students use triple balance beams and graduated cylinders to take measurements and calculate the densities of several common, irregularly shaped objects with the purpose to resolve confusion about mass and density. After this activity, conduct the associated Density Column Lab - Part 2 activity before presenting the associated Density & Miscibility lesson for discussion about concepts that explain what students have observed.

Concluding a two-part lab activity, students use triple balance beams and graduated cylinders to take measurements and calculate densities of several household liquids and compare them to the densities of irregularly shaped objects (as determined in Part 1). Then they create density columns with the three liquids and four solid items to test their calculations and predictions of the different densities. Once their density columns are complete, students determine the effect of adding detergent to the columns. After this activity, present the associated Density & Miscibility lesson for a discussion about why the column layers do not mix.

After students conduct the two associated activities, Density Column Lab - Parts 1 and 2, present this lesson to provide them with an understanding of why the density column's oil, water and syrup layers do not mix and how the concepts of density and miscibility relate to water chemistry and remediation. Topics covered include miscibility, immiscibility, hydrogen bonds, hydrophobic and hydrophilic. Through the density column lab activities, students see liquids and solids of different densities interact without an understanding of why the resulting layers do not mix. This lesson gives students insight on some of the most fundamental chemical properties of water and how it interacts with different molecules.
