What does it take to make it in the Arctic? Learners examine the cold weather adaptations of a polar bear that help it survive. With everyday objects, they model these characteristics as they become make-shift polar bears. Modeling helps...

Let there be light! When your physics learners take this midterm exam, light will be their focus. They will show what they know about electromagnetic waves, interference, refraction, reflection, lenses, prisms, and more! The test is...

Learners investigate magnetic evidence that supports the theory of sea floor spreading.

Why did Stephen Douglas support the Kansas-Nebraska Act of 1854? Why did Abraham Lincoln oppose it? Young historians examine how the Kansas-Nebraska Act of 1854 affected the political balance between free and slave states and explore how...

National Chemistry Olympiad tests are released after their use each year, since they cannot use them again for this event. The result: outstanding comprehensive assessment resources for general chemistry classes! This 2005 version covers...

A full-fledged practice final prepares pupils for their general chemistry final exam. If they complete these 57 multiple-choice questions correctly, they will be well-prepared. Note: even though the questions are multiple-choice, there...

Biology learners should understand a few chemistry basics. Here is a worksheet that introduces them to the concepts of chemical reactions, molecular bonding, and the unique combination of properties that make water vital to life....

For this polar animals writing worksheet, students complete sentence starters that use polar animals, then write several sentences to continue their "story." A reference website for additional resources is given.

Students research bears and their characteristics with a specific study on North American bears and polar bears. In this bear study lesson, students read books about polar bears and wild bears. Students complete activities to further...

Young scholars compare and contrast different types of light on the electromagnetic spectrum.  In this investigative lesson students create a photographic image that demonstrates the infrared, ultraviolet and polarization...

In this math worksheet, students use the polar coordinates to find the Euclidian coordinates. Then they compare points on the coordinate plane.

In this light topics science worksheet, students read selections about fiber optics, fluorescent light, incandescent light, total internal reflection, polarization, glow-in-the-dark light, and lasers. Students then respond to 32...

In this math worksheet, students investigate vectors and polar coordinates. They convert the paths of polar coordinates to Euclidian points.

In this math worksheet, learners examine the graph in polar coordinates of r = f(θ). Then they sketch a graph of the modified functions indicated.

In this math worksheet, students investigate different types of functions and coordinate systems. They review that when integrating a function over a region in the plane using polar coordinates, a “magical” factor of r appears in the...

In this Cartesian coordinates learning exercise, 11th graders solve and complete 4 different multiple choice problems. First, they express each of the Cartesian coordinates provided as polar coordinates. Then, students find the Cartesian...

Students study bears. For this science lesson, students compare black, grizzly and polar bears. Students measure the bear tracks and compare the bear habitats and diet.

Every sort of chemical bond is touched upon during this assignment. Chemistry whizzes identify what type of bond is formed by analyzing chemical formulas or Lewis structure diagrams. Multiple choice questions also ask learners about...

Radioactive decay, pH, properties of elements, organic compounds, and stoichiometry are all touched upon through this practice chemistry exam. It always helps learners to take a practice test in preparation for the actual exam. This...

In this global warming worksheet, climatologists examine a few possible results of climate change. There is no specific reading from which learners extrapolate the information needed to answer the questions, so you will need to preface...

Students use technology and listening skills to explore the sounds of their environment. For this environment observation lesson, students read Polar Bear, Polar Bear, What Do You Hear? in order to identify the sounds in the story;...

In this compounds worksheet, students draw the Lewis structures, indicating the molecular polarity and the major intermolecular force in each compound. This worksheet has 10 problems to solve.

Young scholars read Polar, The Titanic Bear by Daisy Corning Stone Spedden. They complete a variety of cross-curricular activities surrounding this true story of a toy bear that survived the sinking of the Titanic. Included are reading,...

In this algebra game, students pair off to plot polar coordinates on a circular graph. They attempt to hit each other by guessing their opponents location on the graph. This is a great way to reinforce the concept of polar coordinates....
