Submitted as part of the California Learning Resource Network (CLRN) Phase 3 Digital Textbook Initiative (CA DTI3), CK-12 Foundation’s high school Biology FlexBook covers cell biology, genetics, evolution, ecology, botany, zoology, and physiology. This digital textbook was reviewed for its alignment with California content standards.

Students will display their understanding of the symbolism and references that Dr. King used to enrich his famous speech on August 28, 1963 from the steps of the Lincoln Memorial by constructing a "jackdaw," a collection of documents and objects.

This site features World Wind 1.3, a NASA Learning Technologies application that lets the user zoom from any satellite altitude into any place on Earth. It features 3D Engine, Blue Marble, Landsat 7, SRTM, Animated Earth, MODIS, GLOBE, Country & State Borders, Place Names, Visual Tools and Landmark Set. The user can download World Wind, reference an online manual, post to an online forum, view screen shot examples from various satellites, and read press coverage about World Wind.

This task is written so that students have opportunities to use different strategies to determine whether a set has an even or odd number of objects.

What is a black hole? How is it formed? And where are they?

In this video, learn from Space Science specialist Douglas Equils about one of the most massive and mysterious things in our universe, black holes.

This video segment from Between the Lions uses a fun hip-hop song about names to highlight the /uh/ sound that the letter u makes and to boost phonemic awareness--an understanding of the sounds within words.

In this video we take a look at how devices connect to each other. We take a quick look at the Open System Interconnect Reference Model (OSI), Coaxial cable, Twisted Pair Cable, and Fiber-optic Cable.

"All human beings are born free and equal in dignity and rights." This is what it says in the very first Article of the Universal Declaration of Human Rights. The idea of Human Rights is one of the most important fundaments of human co-existence. At the same time human rights are subject to fierce debates and Human Rights violations are common all over the world.

But what exactly are Human Rights? Who is responsible for protecting them? And do they really apply to all people? These are the question the newest animated Video clip in the WissensWerte series deals with.

Students will analyze scenes from the Trojan War that are visually depicted in an ancient object and an 18th-century painting. They will research an epic poem inspired by the Trojan War and write a literary response analyzing how themes and values in the poem reflect the historical context in which they were made. Finally, they will work in teams to reframe a tale from the Trojan War in a contemporary context -- visually and in poetry -- and recite the tale in a poetry slam.

Students observe and study insects depicted in a seventeenth-century drawing. They identify characteristics common to all insects and those unique to particular species. Students research and draw insects, incorporating a variety of lines and shapes and using value to depict three-dimensionality.

Students will learn about axial movements and locomotor movements by discussing dancers depicted in a drawing and photograph. They will then practice combining axial and locomotor movements. They will describe how artists depict a dancer's motion in drawing and photography. They will also analyze how an artist creates movement and emphasis through contrast, composition, and leading lines, and then experiment with photography to capture motion in dance.

Students will learn about the Impressionist painters' use of color and how it connected to early-19th-century scientific theories about color. They will explore combinations of primary and secondary colors, experiment creating secondary colors, and create a landscape using complementary colors.

Students work in groups to create annotated book reviews with links to topics of interest related to their book.

Students really get into character in this lesson as they act out the parts of a script and analyze character motivations and dialogue.

Loopy dot diagrams uses fruit loops as a manipulative to help students develop the basic skills for making Lewis dot structures to model covalent bonding.

Using the scientific method this simple hands on experiment is designed to verify Newton's Second Law.

This calculus course covers differentiation and integration of functions of one variable, and concludes with a brief discussion of infinite series. Calculus is fundamental to many scientific disciplines including physics, engineering, and economics.

This module of the course focuses on organizing curricular documentation and student learning evidence into a reflective exhibition or narrative that explains student learning and what inclusive educational practice supported that learning. During the module you will use a scoring rubric to help analyze some sample cases and give constructive feedback to improve the educative value of the cases or exhibitions for other educators.

Most books that use MATLAB are aimed at readers who know how to program. This book is for people who have never programmed before. As a result, the order of presentation is unusual. The book starts with scalar values and works up to vectors and matrices very gradually. This approach is good for beginning programmers, because it is hard to understand composite objects until you understand basic programming semantics.
