Groups will share their presentations with the class.
Students will learn about the importance of
radio astronomy to the study of space.
After reviewing radio waves students will participate in a hands-on
activity that models how radio telescopes work. Once they understand how the
data is collected students will investigate one of the telescopes and learn
about the important work done at that location.
Students and adults alike listen to the radio with little thought as to what the FM and AM band numbers actually mean. This introductory activity will offer students some local context to radio frequency and extend their thinking to where those signals come from and how else they are used. Students will have a chance to tune a radio receiver and explore radio waves.
Students will learn how satellites are used to predict weather. Then the class will use images from the satellites to predict thunderstorms.
During this lesson, students will discover what 5G phone coverage is and develop an understanding of why some areas have it while others do not. They will take one of three positions on the topic of 5G and debate the most appropriate use of certain frequencies. Finally, students will learn about the economic side of 5G as the class discusses spectrum auctions.
This lesson introduces students to how planes are tracked using radio waves. The lesson continues as students collect data on local planes and use this information to calculate the net force acting on the aircraft according to Newton’s second law of motion.
Students will learn about a device that can receive radio signals in the classroom. They will research methods of improving reception and use that knowledge to create a solution to the problem.
During this lesson, students will be introduced to Radio astronomy and the telescopes that are used in the discipline. They will then be challenged to design a dish for a brand-new telescope.
During this lesson, students will learn about the wave and particle nature of electromagnetic waves. Students will also learn about the diffraction of light and conduct an experiment to determine the thickness of a piece of hair. Students will also observe the diffraction pattern of burning gas when viewed with a diffraction grating, thus understanding how astrophysicists know the compositions of stars. Students will also learn about how diffraction of electromagnetic waves affects telescope resolution and what can be done to mitigate the effects as well as learn about how radio signals diffract when hitting the edge of an obstacle, dispersing the signal and causing weakened signals.
In this lesson, students will learn how electromagnetic waves are created. They will also participate in four learning stations to help them better understand the creation and properties of these waves. Lastly, they will make a 3-D model of an electromagnetic wave that they will use as a learning tool.
In this lesson, students will learn about the categories of electromagnetic waves. They will investigate the uses and dangers of one type of these waves and share their findings with peers. Finally, they will debate how one section of the spectrum should be used.
Students will understand how data from radio telescopes are used to create images of celestial objects. They will further explore ways to enhance visual representations of the data by including sound using Afterglow Access sonification software tool.
Students will choose a radio wave application that they would like to research and compile the most pertinent information to present and share with the class about the uses and applications of radio waves. Students will work in teams of 2-4 people to research, create, and design the best digital and oral presentation.
Students will research how a radio sends and receives AM and FM signals. Students will then design and construct a crystal radio. Finally, students will demonstrate their knowledge of how a radio works using electromagnetic radiation by creating a presentation, flier, or poster to showcase their expertise.
Students will use their knowledge of radio frequencies to design and carry out an investigation of Wi-Fi strength around the school. The data will be analyzed and presented to school staff in an effort to improve connectivity.
During this lesson, students will see the radio waves passing through their areas visualized on the screen in the classroom. Next, students will work in small groups to identify the broadcasters of these waves. Lastly, students will work independently to write a persuasive essay about how the spectrum should be shared among users.
Students will investigate and discuss the health effects of radio frequencies. Then they will present their argument in an eye-catching presentation.
The students will learn about the fundamentals of the electromagnetic spectrum. Radio frequency will be emphasized, especially its usage in science, astronomy, wireless communication and modern applications. Finally, the RTL-SDR dongle will be presented to the students. This device will be used to identify local radio broadcasters.
Students will use their knowledge of seafloor features to learn about the movements of marine organisms (e.g. sharks). They will gain an understanding of how marine animals are tagged and tracked with satellite technology as well as gain insight regarding the pros and cons of learning about animal behavior.
Students will learn how satellites collect data and communicate that information with researchers on Earth. Students will use this data to create a thermal map using isotherms. Lastly, students will use the satellite data to determine changes in sea surface temperature.
This lesson reviews the fundamentals of mechanical waves. First, teachers will instruct students in the parts and movement of waves. Then students will work in small groups on several short inquiry activities that will allow them to understand the characteristics of waves.
The lesson begins by introducing students to how satellites are involved in worldwide communication. Students will first learn about the basics of satellites, including the different sizes and orbits. Then the class will focus on investigating specific satellites. Finally, students will read about how satellites may interfere with other spectrum users. The lesson will conclude with a discussion on the topic.
Students will use their knowledge of the electromagnetic spectrum to build a spark gap transmitter. The device generates pulses of radio waves that are detected with an AM radio receiver.
Students will investigate the local users of the spectrum and learn about additional users that are not in their area. Then students will work in small groups to create a priority list of spectrum users. The lesson will conclude by students comparing and contrasting their priority list to the priorities set by the federal government.
This lesson describes the extensive use of radio waves. Students will learn that radio frequencies have numerous applications, and require government regulation to prevent interference and unfair competition. In addition, students will have a chance to investigate their own questions regarding radio.
Students will learn about how weather satellites work and then analyze some of the pictures created from the data. Students will also learn how Doppler radar works. The lesson concludes with students writing a paper about the role of radio waves in weather forecasting.
During this activity, participants will gain an understanding of how radio telescopes collect and analyze data.
* These lessons were created by the National Radio Astronomy Observatory (NRAO) as part of the National Radio Dynamic Zone (NRDZ) project. They were created by Valarie Bogan who is an experienced classroom educator and has a Ph.D. in Science Education and a certificate in K-12 Integrated STEM education. These student-centered lessons combine hands-on activities, inquiry investigations, and small and whole-class discussions to build a deep understanding of radio frequencies.
** These lessons were created during a summer teacher experience that was part of the SpectrumX program. Educators were recruited from across the US and its territories to participate in Radio frequency workshops which were hosted by spectrum experts. The educators then used that knowledge and best practices to create these lessons.
The educators attempted to incorporate culturally inclusive/responsive elements and best practices in the lessons during both projects.
