Starting with similar triangles and dilation factors, this unit quickly and thoroughly progresses into the world of right triangle features and trigonometric relationships. Presented in easy-to-attack modules with copious application...

Connect the dots on trigonometry with K'nex. Scholars use a K'nex model of a Ferris wheel to collect data points to plot on a height versus time graph. They'll then consider what type of function best models the data in the graph—and...

Students investigate the different properties of trigonometry. In this precalculus lesson, students find the six different identities of trigonometric ratios. They relate the ratios to that of a right triangle and apply it to real life...

Students calculate the different ratios using a right triangle. In this trigonometry lesson, students identify the sine, cosine and tangent of each side. They find the missing angles using the different ratios.

Students solve problems using sine and cosine. In this trigonometry lesson, students apply the properties of sine and cosine to solve triangular problems. They identify when to use law of sines using angle-side relationships.

You and your learners will enjoy having a nicely organized, typed up unit circle, all filled in with degrees and radians as well as cartesian coordinates. 

Students identify the six trigonometric ratios and properties. For this trig lesson, students define basic trig functions as it relates to solving right triangles. They identify the equation for sine as o/h and cosine as a/h and tangent...

Students play the role of science detectives in an activity used to introduce the scientific method and the concept that blood is not identical and is identified by surface markers. Students must identify an unknown sample of "blood" by...

Students are encouraged to use senses other than sight to record observations. They explore scientific questioning, observations and human senses (touch, hearing and sight). Students describe objects using their sense of touch and then...

Students model scenarios using functions and their properties. In this trigonometry lesson, students calculate the angles of sine, cosine and tangent. They perform operation using a calculator.

Students define the law of cosine and its correct usage. In this trigonometry lesson, students define the law of Heron's area formula and use it to solve problems. They review other trigonometric values and identify the identities.

Young scholars solve problems using the Pythagorean Theorem. In this geometry lesson, students identify the sides and angles of a right triangle. They find the different trigonometric ratios and solve using sine, cosine and tangent.

Learners determine the trigonometric relationships within a triangle as they construct a right triangle on the Ti-89. They find the sine, cosine, and tangent of various angles of their triangle construction.

Ninth graders differentiate between energy waves transmitted from a quarry or mine as opposed to energy waves transmitted by an earthquake. They analyze seismograms of blast events from at least two quarries or mines. The energy waves...

Students explore the exciting world of mammals as they learn the identities of some Wisconsin native residents. They examine their adaptations and learn how they survive in a state with a wide array of temperatures and ecosystems.

Students find the identity o sine, cosine and tangent. In this precalculus lesson plan, students solve and identify the different parts of a right triangle. They use the ratios of the Pythagorean Theorem to find the missing side or angle.

Students find the different ratios of a right triangle. In this geometry lesson, students apply the concept of the Pythagorean theorem as they identify the different angles and parts of a Unit Circle. They find the ratios of sine,...

Introduce starting space scientists to the electromagnetic spectrum, expecially the portion of visible light. Teach them about wavelength and frequesncy. Then give them a roll of adding machine tape and a manila folder to make a...

Examine the concept of variation through observation and measurement. Middle schoolers will study a peanut and record any distinguishing characteristics visible as well as sketch their peanuts and describe them in writing. Their peanut...

Circles are the foundation of many geometric concepts and extensions - a point that is thoroughly driven home in this extensive unit. Fundamental properties of circles are investigated (including sector area, angle measure, and...

Examine the concept of an electromagnetic spectrum with your students, as they observe a demonstration of a model, construct and compare a different model of the spectrum commonly used in textbooks, and construct their own models of the...

Students are introduced to the various types of dinosaurs and write in their journals about their favorite one. After listening to a story and watching a filmstrip, they color a few pages in their Dinosaur Friends Book. They also examine...

Learners create a model of DNA and simulate replication with their models in an activity that uses licorice, colored marshmallows, and toothpicks. Students also label a diagram of replication and indicate major parts of the DNA molecule.

Students create a checklist of traits common in all of their families. Uisng a table, they compare and contrast their family members to non-family members. They also review dominant and recessive traits and discuss how knowing about...
