Logic is used across domains and is necessary for everyday functioning. Writing proofs allows students to practice their logic skills. Thus, students will be engaged with proofs in the form of a game to engage their attention. These rules can be used to justify certain moves. The lesson has an activity that uses the game of Uno to introduce proofs. Understanding the characteristics of polygons will help students to describe the world around them. Polygons are all around students in the world (architecture, art, etc.). In this lesson, students recall their knowledge of polygons which will catch their attention because it allows them to draw from what they know, which is a different means of expression than is typically used. 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) The final activity, Create a Sundial that Correctly Displays the Time of Day, is an outdoor STEM project that challenges students to build a functional sundial, helping them understand how the sun's placement in the sky creates observable patterns in Earth science phenomena such as climate changes, weather patterns, and shifts in the planet over time. In the second activity, Patterns in the Sky, students will construct a tower outside and measure how shadows change throughout the day. The first activity, What Makes a Shadow, serves as a hook to assess students' prior knowledge of shadows and helps build vocabulary by categorizing objects as opaque, translucent, or transparent. This lesson plan consists of three distinct activities that can be completed separately or as a cohesive unit. Sunshine, Shadows, and SCIENCE! (.pdf, 470kb) The lesson will emphasize the importance of taking multiple samples and averaging data to increase the probability of accurate results and encourage students to apply what they have learned to future scientific investigations or environmental projects. Through watching a video about the Great Wildebeest migration, participating in a lab activity to collect data on Devil Weed, and engaging in class discussion, students will explore the complex interactions between wildebeests, grass/resource, and Devil Weed, and evaluate claims, evidence, and reasoning in ecosystems. This lesson plan is to help students understand the impact of Devil Weed, an invasive species, on the ecosystem in Serengeti National Park. This lesson plan is designed to foster critical, creative, and collaborative thinking in middle students and to explore the complex relationship between technology, humanity, and ethics. By using fun activities, class discussions, and hands-on training of an AI system, students will gain a deeper understanding of how AI works, its possible purposes, and the ethical considerations that should be considered when designing and using machines. This lesson plan is to engage students in an interactive and thought-provoking learning experience that connects the concepts of emotions and artificial intelligence. 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.
