Help learners discover the unique characteristics of the tangent function. Working in teams, pupils create tables of values for different intervals of the tangent function. Through teamwork, they discover the periodicity, frequency, and...

Translating complex numbers is as simple as adding 1, 2, 3. In the ninth lesson in a 32-part series, the class takes a deeper look at the geometric effect of adding and subtracting complex numbers. The resource leads pupils into what it...

How do you graph a quadratic function efficiently? Explore graphing quadratic functions by writing in intercept form with a instructional activity that makes a strong connection to the symmetry of the graph and its key features before...

Math is all about finding solutions and connections you didn't expect! Young mathematicians often first discover nonlinear patterns when graphing quadratic functions. The lesson begins with the vocabulary of a quadratic graph and uses...

What does it take to show two triangles are similar? The 11th segment in a series of 16 introduces the AA Criterion for Similarity. A discussion provides an informal proof of the theorem. Exercises and problems require scholars to apply...

Is there one, none, or more? Through discussion or activity, scholars find the properties of an equation that will determine the number of solutions. They then use the properties discovered to figure out the number of solutions...

Challenge the class to determine the equation of a line. The 21st part in a 33-part series begins with a proof that every line is a graph of a linear equation. Pupils use that information to find the slope-intercept form of the...

Wiggle your way through lab day! Young zoologists observe and infer the effects of different stimuli on earthworms during an engaging lab from the K20 series. Lab partners set up four different controlled environments, then record how...

In this physics worksheet, students answer 5 conceptual questions about the sensitive audio detector they built. They analyze the component of their circuit.

Students explore the concept of fractals. In this fractal lesson plan, students use applets to explore Koch's Snowflake, Sierpinski's Triangle, and other fractals. Students develop these concepts through exploration and teacher guided...

Students conduct an experiment to change the color of E. coli bacteria using genetic engineering. They work in small groups to add a plasmid containing a gene for red pigment to the bacteria and culture the bacteria to see if it ...

Students design and carry out an investigation to test which materials is the best insulator: they predict which way heat energy flows in a system and analyze the flow of energy in a system from one point to another and from one form to...

Students explain that heat energy in a material consists of the disordered motions of its atoms or molecules. They know and explain that transformations of energy usually transform some energy into the form of heat, which dissipates by...

In this inverse matrix activity, students find the product of matrices. They generate an inverse matrix using the Gauss-Jordan elimination method. This two-page activity contains explanations, examples and two practice problems.

In this image processing worksheet, students use a matrix to solve ten problems. For the first six problems, students are guided to the answer by carefully sequenced questions. The final four problems require students to make a series of...

In this Algebra II worksheet, 11th graders graph root functions and analyze the domain, range, intercepts, maximum and minimum values, and end behavior.  students use that information to transform the graphs of root...

Students investigate simple machines. In this simple machines lesson, students study how simple machines work. Students determine the function of various simple machines.

Students explore how the sounds made by everyday objects can be transformed into musical experiences, composing and performing musical pieces using non-traditional instruments.

Students examine and identify polyhedron shapes on a math website. They write journal reflections about two- and three-dimensional shapes, and transform a square into a pinwheel.

Students examine and analyze struggle for racial and gender equality, influences on African-American culture during the 1920s, and economic boom and social transformation of post-World War II United States.

Students discuss how people are influenced by their cultures and backgrounds, make artwork that documents creative process, write character sketch of Colonel Massey from different points of view, examine issue from different perspectives...

First graders explore the characteristics of solids and liquids. In groups, they generate ideas on how a solid is transformed to a liquid and back to a solid. They make predictions on how the process can be speeded up with a partner. ...

Students explore the events and reactions surrounding the Dust Bowl crisis during the 1930's. They discuss how the events of the Great Depression affected America's democracy and how it transformed America.

Sixth graders write myths to show tolerance in creation. They read from both the Aztec and Mayan eras and develop an understanding of the similarities and differences of these two closely related cultures. They track the travels of...
