Then students will examine parts of a sine wave such as the period, amplitude, and asymptote which will allow them to identify the parts of cosine, cosecant, secant, tangent, and cotangent graphs. The lesson will launch by recognizing sinusoidal waves in the real world such as visible waves. Students will learn to recognize the graphs which will be important in future lessons as well as in other disciplines. In this lesson students will explore how to graph trigonometric graphs and identify the period, amplitude, and asymptotes. Graphing the Trigonometric Functions (.pdf, 3mb) The data reviewed in this lesson come from a data set collected about women who came in continual contact with radioactive materials, which were used in Oak Ridge laboratories. At the same time, students will investigate, research, and write about the effects of overexposure to radium, which can cause mutations in the human body.

This lesson will allow students to use career-related, real-world data from the DOE’s Comprehensive Epidemiologic Database Resource (CEDR) to improve math skills. Radium Girls: A CEDR Lesson Plan (.pdf, 1.2mb) Lastly, the students will be challenged to plan and carry out an investigation of the life cycle of a plant by growing a plant from a seed and recording its changes over a period of time. Students will then organize picture cards of the seed germination process in order and detail what is occurring at each step.

In this lesson, students will familiarize themselves with the germination process through videos, observations, questions, and sorting/analysis of seeds. Resources for K-12 Teachers and Students.Students will use UV beads and expose them to UV light to determine the level of exposure through each different type and SPF level of sunscreen. Students will work together in small groups of three to four and practice using the scientific method to create a methodology that tests the effectiveness of different sunscreens to protect people from ultraviolet radiation. Students will learn the basic properties of waves and light.

In this lesson, students will learn how they can protect themselves against the harmfulness of ultraviolet (UV) radiation and interactions of light. Whether it be living in a sunny place, vacation, or just laying on your porch tanning in the summer, students are constantly being exposed to the sun’s harmful radiation.
