By mounting a light bulb on a stand and a PV cell on another, physics apprentices experiment with the angle of incidence. Their goal is to determine the optimum angle for collecting solar energy. The use of a scientific calculator...

Challenge the class to prove that the dilation properties always hold. The lesson develops an informal proof of the properties of dilations through a discussion. Two of the proofs are verified with each class member performing the...

Students experiment with paper, light, thermometers and measurement to explore how the Sun's angle affects the temperature on Earth.

In this refraction through a triangle activity, students use a given diagram of light striking a triangular piece of plexiglass to determine the light ray's angle of incidence, the ray's angle of refraction, they use Snell's Law to...

For this refraction through a circular disk worksheet, high schoolers are given a diagram of a circular disk of leaded glass with light striking it. Students use the diagram to find the angle of incidence of the light, the angle of...

Collaborative groups work with geometry manipulatives to investigate conjectures about angles. They create a graphic organizer to use in summarizing relationships among angles in intersecting, perpendicular and parallel lines cut by a...

Seventh graders use a protractor to measure angles and solve a problem involving distance. In this measuring angles with a protractor lesson plan, 7th graders calculate the distance of a line on a diagram by using a protractor to measure...

Students discover the different types of mirrors, their properties and some of their applications. They have already been introduced to some of the properties of light and have already experienced some of the different types of mirrors...

Students use similar triangles to find missing heights.  In this using similar triangles to find missing heights lesson, students use proportions to find the heights of missing side lengths.  Students find the height of trees...

Your geometry learners explore Angle-Side-Angle congruence in this collaborative task. The sum of the interior angles of all triangles being one hundred eighty degrees, is the key learners will discover as they explain their reasoning...

Set your pupils up to start on geometry by teaching them some introductory terminology. Pupils learn the terms by reading a short passage and looking at examples. They then respond to five questions related to the text.

Given a value of one trigonometric function, it is easy to determine others. Learners use the periodicity of trigonometric functions to develop properties. After studying the graphs of sine, cosine, and tangent, the lesson connects...

Fifth graders practice the concepts related to finding and identifying different angles. There are examples included in the lesson plan that are useful for the teacher to deliver the lesson plan.

Students are introduced to lines, rays, line segments and planes and study the differences between them. They also practice graphing lines, rays, line segments and planes

Sixth graders explore different geographic relationships in like drawing lines, rays, and parallelograms. This lesson could be used for review because it covers more than one concept. The students should have prior knowledge.

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

Students estimate and accurately measure the size of angles communicate with the appropriate geometric terms and symbols to describe and name angles, lines, line segments, rays

Don't worry, optics is a light topic! The presentation covers reflection, refraction, fiber optics, mirages, prisms, rainbows, dispersion, mirrors, lenses, telescopes, diffraction, the human eye, and much, much more. Presentation is...

The Common Core is intended to help all children meet high academic standards. Here is a Common Core designed instructional activity that is intended for learners with communication or language difficulties. The instructional activity is...

Can you use triangles to create a circle? Learners develop the unit circle using right triangle trigonometry. They then use the unit circle to evaluate common sine and cosine values.

A set of 49 math vocabulary cards ranges from angle to irregular polygon to parallel lines. Each sheet contains two cards: one with the word printed in bold text and the other with the definition.

How do jewelers tell the difference between diamonds, glass, and cubic zirconia? A sparkling simulation demonstrates how to use a ray of light to determine the substance and ideal shape for a diamond. Scholars control the material,...

Tenth graders investigate the theorems of angles and lines to prove triagle sum theorem. 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...

Fifth graders use the SMART Board to demonstrate how to use a protractor to measure acute, obtuse, and right angles. In this protractor lesson plan, 5th graders also complete an angles worksheet.
