Students identify similar and congruent right triangles. In this geometry lesson, students use trigonometric ratios to identify missing sides and angles of a triangle. They differentiate similar and congruent triangles.

Learners identify types of arcs and angles in a circle, find the measure of arcs and angles, and solve real world problems involving lengths of segments in circles, lengths, and areas.

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...

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...

All aspects of the path of light are included in a great summary. Internal reflection and the angles of paths in different materials are explained and the behavior of visible light through lenses and the effect on focal points are...

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...

Pupils 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.

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.

Young scholars 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.

Young scholars study elevation of the Sun above the horizon and the angle of the rays and their heating power.

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.

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.

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...

Students 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 light...

Tenth graders investigate the theorems of ASA, AAS, AAA and ASA. In this geometry lesson, 10th graders discuss the theorems of triangles and how it is used to solve for missing sides or angles. They review how two angles are formed by...

Middle schoolers 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...

Young scholars identify the types of light on the visible spectrum. They identify relationships between angles and mirrors. They state how they use light in their everyday lives.

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.

For this angle vocabulary card worksheet set, students identify the vocabulary associated with angles such as: ray, vertex, acute angle, segment bisector, and corresponding angles. They identify 23 terms but there are no questions...

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.

In this optics worksheet, high schoolers 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...
