Sixth graders investigate the phases of the moon. In this moon phase lesson, 6th graders discover that the moon changes in a cycle as it orbits Earth. Students label pictures of moon phases and keep a moon phase journal. Students...

Twelfth graders discuss sine curves and enter equations into their graphing calculator then compare different graphs created on their calculators. They identify the period, amplitude and phase shift given the graph or the equation of a...

Learners explore circular functions. They identify the amplitude, period, phase shift and vertical shift of circular functions. Students analyze phenomena described by sine waves and they find mathematical models for transforming images...

Young scholars create a model of the phases of the Moon by giving students pictures of the phases of the Moon, a picture of the Earth, and a picture of the Sun. They then take a picture, and stand in correct place to make the phases of...

Students analyze graphs. In this trigonometric lesson, students identify the different graphs of sine, cosine and tangent. They graph the inverse of those trig values and identify their properties such as phase shift and period.

Students investigate angles converting them from radians to degrees. In this trigonometry lesson, students work with angles and the six different trig ratios. They graph the functions representing each trig functions and identify the...

Students determine what occurs in the final stages of the development of a rice plant. In this rice plant development activity, students use the associated study guide to list the three stages in the ripening phase of rice development....

Students examine where trigonometry exists outside the classroom. In this trigonometry lesson, students create trigonometric functions to match the data provided and to solve word problems relating to the real world.

Young scholars recognize dependent and independent variables in an experiment by practicing manipulation of variables; students practice designing experiments that contain the two types of variables.
