Students examine propaganda and media bias, research a variety of banned and challenged books, choose a side of the censorship issue, and support their position through an advertising campaign.

History contains the stories of men, women and children. Biographies and personal histories add to the understanding of a time and place.

Dedicated to the civil, nonpartisan promotion of constitutional literacy within our local, state, and national communities. Focus on 5 areas: Educational Programs, Federalism, The Quill Project, Equal Liberty & the Constitutional Rule of Law, and Property & Free Markets.

Here’s an easy way to find the center of gravity of a long, thin object, even if the object’s weight is unevenly distributed.

The purpose of this task is to use geometric and algebraic reasoning to model a real-life scenario.

The purpose of this task is to use geometric and algebraic reasoning to model a real-life scenario. In particular, students are in several places (implicitly or explicitly) to reason as to when making approximations is reasonable and when to round, when to use equalities vs. inequalities, and the choice of units to work with (e.g., mm vs. cm).

Open Middle provides math problems that have a closed beginning, a closed end, and an open middle. This means that there are multiple ways to approach and ultimately solve the problems. Open middle problems generally require a higher Depth of Knowledge than most problems that assess procedural and conceptual understanding.

This video talka about what is easily one of the most fundamental and profound concepts in statistics and maybe in all of mathematics. And that's the central limit theorem.

In this interactive activity from NOVA, discover how centripetal force can affect you when riding in a car or flying at high speeds in a fighter jet.

This video segment explains centripetal force and illustrates how roller coasters rely on it to give you a thrilling ride.

Students will learn the basics about cereal grains. They will learn the main seven types of grains, the nutritional value found in cereal, and they will cook with a grain. They will also be able to taste cereal and compare cereal with and without sugar being added.

This article is an overview of the life of Cesar Chavez and his efforts to promote civil rights. Access to this resource requires a free educator login.

In 1968, Cesar Chavez led a boycott that resulted in a collective bargaining agreement guaranteeing field workers the right to unionize. Learn more about how Chavez grew from migrant farm worker to civil rights champion in this video

In lesson plan, educators will learn to teach students to perform the basic Cha Cha step with the correct timing, footwork, and body placement.

Chad Hasegawa paints portraits of bears and notable artists, and his style is influenced heavily by the Abstract Expressionist movement, and a thrifty approach to materials. He has created murals throughout San Francisco and shown his paintings and sculptures in galleries. His work balances between abstract and figurative art, with dense, wild brushstrokes that are often pieced together to create recognizable forms.

This activity gives students practice naming and using shape and color attributes to create patterned sequences. The first challenge asks students to use attribute differences to extend a sequence. A second, more open-ended challenge asks students to maximize the length of their sequences under a further constraint. An interactive applet is provided as an alternative to physical manipulatives. The Teachers' Notes page includes suggestions for implementation and discussion questions.

This activity gives students a chance to relate some common three-dimensional solids to their polygonal faces. The object is to put solids in a sequence in which adjacent solids have a polygonal face in common. Ideas for implementation, extension, hints and support are included along with printable cards of the polyhedra.

This hands-on activity helps students develop spatial sense and scaling concepts. Students use interlocking cubes to build first a chair and then a table of appropriate size for the chair. The student goes on to build two other sets of chairs and tables to make three different sizes in all. The Teachers' Notes page includes suggestions for implementation, discussion questions, and ideas for extension.

This list contains materials that can be used to complete CBL projects in any learning environment. All materials are available online, and some are available in stores as well. These items are things that we have used here at the Leonardo for activities before. The links are purely for your information; we do not receive anything if you use a link.
