Students identify and use the similarity theorem. In this geometry lesson, students differentiate between congruent and similar triangles. They solve problems using the computer modifying shapes by dragging.

Learners identify the ratios of trig functions. In this trigonometry lesson, students construct triangles and use it to derive the values of sine, cosine and tangent. They use Cabri software to create the visual of the identities.

Investigate dilations to learn more about them. The second segment in a series of 16 provides a discussion of properties of dilations by going through examples. The problem set provides opportunities for scholars to construct dilations.

Here is a stellar slide show for illuminating middle schoolers' minds on the topic of light! An interactive slide allows viewers to sort light sources by whether or not they are man-made. More objects are displayed and learners discover...

In this mind-bending activity, young engineers explore this question of whether or not light actually bends. Using holographic diffraction gratings, groups design and build a spectrograph. The groups then move on research a problem...

Display this list of commonly misspelled and frequently confused words for your learners. Though there is no interactive component, this handout is a great reference tool comparing many homophones such as sole and soul. One tip...

Need to go over some math concepts with your third graders? Use a series of math posters, featuring vocabulary words in geometry, measurement, fractions, probability, and many other areas of study. Each poster presents the term with an...

Students define and discus the concepts of wave fronts and rays. In groups, they distinguish between specular and diffuse reflections and use Snell's Law to predict the path of light rays. They calculate the speed of light through...

Young scholars observe and demonstrate a variety of basic geometric constructions using the Triman Safety Compass. Using the compass, they draw circles, bisect a line segment, construct an angle, bisect an angle, copy an angle, and...

Students, as a final project, draw a picture of their ideal neighborhood on a sunny day. In addition to the sun, their drawings include homes, trees, streets, and selected objects. Each object in their drawing has a written description...

49Students investigate the properties of right triangles. In this geometry lesson, students differentiate between similar and congruent triangles. They use the Pythagorean Theorem to find the missing angles and sides.

In this biomes worksheet, students read an article on biomes and answer 10 multiple choice, short answer or true and false questions relating to biomes.

In this math worksheet, students sketch six integrals and rewrite the equations as double integrals with reversed integration orders. Students evaluate four integrals. They sketch all points on a coordinate plane when given complex...

Fifth graders explore angles by using protractors. They recognize, describe and determine the surface area and volume of three-dimensional shapes. Students recognize the right angle, acute angle, obtuse angle and vertex. They identify...

In this identifying figures worksheet, students match 10 figures to the correct vocabulary terms that include lines, angles, shapes, and segments.

Students conduct a close examination of the atom's electrons, and discover how to theorize the energy levels, observe the brightness of light, classify colors, and measure temperature.

In this math worksheet, students read the examples for using the techniques of mathematical modeling. They draw the angles in order to simulate the reflection of light while using a concave mirror.

For this optics worksheet, students read about refraction and reflection, lenses and mirrors, and objects and images. They answer 13 matching questions about light rays, light behavior and types of lenses. They also answer 9 questions...

In this optics worksheet, students read about how light can reflect or refract and how lenses and mirrors work. Then students complete 13 matching, 27 fill in the blank, and 8 word problems.

In this stars rise in the east worksheet, students use geometry to show how the Earth rotates from west to east and why celestial bodies appear to rise in the east and set in the west. Students draw a figure and label given points in...

Young scholars study what makes Earth warm and explore how different locations on the planetreceive different amounts of solar energy based on the intensity of the sun's rays. They calculate light intensities and compare the amounts of...

Students explore energy by creating a light project in class. In this kaleidoscope lesson, students discuss the properties of light and how mirrors can reflect the energy in different directions. Students view a diagram of light...

Students examine how navigation is based on mathematics and how making a mistake in measuring an angle could have an impact on a target. They observe a teacher-led lecture, use a calculator to complete two worksheets, and participate in...

In this climate worksheet, students read 4 statements about different causes of climate patterns or weather changes. Students write in the effect of these causes in this graphic organizer.
