Let the energy blow. Using mostly easily found material such as PVC pipe and fans, pupils build wind turbines. Scholars connect a multimeter to an electric motor to determine the amount of energy generated by their designs. Learners then...

All you need is light. Groups use a reflectometer to find the reflectivity of specific chemical compounds. Learners compare the graphs of the reflectivity of the known compounds to Martian soil. Using the graph comparisons, scholars...

Correct a misleading conclusion. Individuals review a set of data and a conclusion to determine what is wrong with the conclusion. Pupils then represent the data with an appropriate display. Finally, learners develop a correct conclusion...

Find out if there are enough squares. Given diagrams for the first four figures in a sequence, pupils try to determine the next figure. Individuals find the number of square and triangle pieces of fabric that are required to make...

Take an overall view of percentages. Pupils determine whether a shop owner's claim is correct about what percent of his shop is viewable from the installed security camera. Learners try to find whether there is a better location for the...

Determine the power hog in the house. Pupils learn the difference between power and energy before participating in a hands-on activity. Using a power meter, pairs measure the actual power used for several household devices, estimate the...

Find a faster way to determine the 100th term of a sequence. Learners watch a video providing instruction on a way to find the nth term of a sequence—without writing down all the previous terms. Scholars create explicit formulas for...

Let's finish a functional review. Pupils work through 31 items to review the concepts learned in Unit 8. Scholars determine whether a mapping is a function and identify the domain and range. Using function notation, individuals then...

Find a solution in the field. An informative video presentation shows pupils how to use the information from a slope field to sketch the graph of a particular solution to a differential equation. Individuals learn how to determine the...

Frolic through a field of slopes. Learners watch a video describing slope fields and how to create one. Scholars use given slope fields to determine the equation of a tangent line and the possible differential equation. Pupils continue...

Prompt scholars to discover the expansion of the universe themselves. Using photographs of other galaxies, they measure and then graph the size and distance of each. Finally, they draw conclusions and prove the universe is...

In this grammar skills worksheet, students read the word choices and identify which determiner is best. Students identify the determiners of a, an, the, some, and many.

Students determine eigenvectors and eigenvalues for a matrix. Students diagonalize a matrix. Similar matrices are defined. Determinant formula is given for an degree n polynomial.

Ninth graders evaluate President Woodrow Wilson's principle of self-determination and its effects today. In groups, they research how the Great Powers dealt with Korea at the Paris Peace Conference and compare their perspectives with...

In this Cramer's Rule worksheet, students first evaluate five determinants or square matrix. Then they solve the last five problems by applying Cramer's Rule. Students identify and define Cramer's Rule as a theorem used with linear...

In this Cramer's Rule worksheet, students use Cramer's Rule to solve system of equations. They identify the value of each given determinant. This one-page worksheet contains ten multi-step problems.

In this Cramer's rule learning exercise, students solve 4 problems in which they find the determinant. They then solve 8 more problems in which they use Cramer's Rule to solve each system of equations.

Young mathematicians represent a triangle with a matrix and use the determinant to find the area of three given triangles. Learners also verify the formula for area of a triangle. 

In this algebra worksheet, students solve systems of equations.  They evaluate matrix problems and identify the determinant.  This two-page worksheet contains 13 problems.

How can you tell the author's purpose from just a short summary? Kids read three different summaries of books to determine whether the author meant to entertain, persuade, or inform.

Help your class develop the ability to determine a main idea with a packet of materials that you can introduce and use over a period of time. The packet includes some information for the teacher and rationale for the exercises. There are...

Searching for a simple igneous rocks experiment to assist pupils with rock classification based on texture and composition? In the activity, pupils view multiple rocks in various ways to determine texture and composition. They then...
