This lesson follows the NGSS standards for reviewing analog and digital waves. Students will be able to review the differences and similarities of analog and digital waves. Students will also be able to review how signals sent as analog or digital waves are used.
This activity is an interactive “out-of-the-seat” demo that allows the students to become involved in learning about fibre optic cables by imitating the way that one basically functions. While enjoying the physicality of the demo the children will pick up basic details of light, reflection, optical properties, and applications to technology. Additionally, the activity will go into details of how fibre optics are used in astronomy technology and how it is used to improve our understanding of the universe. An emphasis should be placed on asking direct questions to the children about how these concepts can influence technology, astronomy, and our world to reinforce the concepts that they are learning about.
The University of Iowa Center for Global and Regional Environmental Research and College of Education teamed up to develop free eighth grade science curricula on land use and climate science, in response to Iowa’s grade level alignment of the middle school Next Generation Science Standards.
Primary author Dr. Ted Neal, clinical associate professor of science education, led a team of graduate and pre-service teaching students and CGRER scientists to develop the material. They grouped standards, resources and lesson material into six bundles, each designed to engage Iowa’s middle schoolers with local data and information on relevant topics like athletic concussions and agriculture.
These lessons are built on NGSS principles and put learning in the students’ hands with hands-on activities for groups and individuals. Kids will have ample opportunity to get curious, generate questions and lead themselves to answers.
Broadcast radio waves from KPhET. Wiggle the transmitter electron manually or have it oscillate automatically. Display the field as a curve or vectors. The strip chart shows the electron positions at the transmitter and at the receiver.

Astronaut Randy Bresnik explains the main ways astronauts communicate with people on Earth. Also learn about how satellites work in a hands-on classroom activity.
Astronaut Scott Tingle talks to us about sounds in space and then "jammed†with host Marty.
This lesson will investigate the difference between longitudinal waves and transverse waves, and how they are able to transmit energy from one location to another.
Students learn about glaucoma its causes, how it affects individuals and how biomedical engineers can identify factors that trigger or cause this eye disease, specifically the increase of pressure in the eye. Students also learn how RFID technologies transfer energy through waves and how engineers apply their scientific understanding of waves, energy and sensors to develop devices that measure the pressure in the eyes of people with glaucoma. Students conclude by sketching their own designs for a pressure-measuring eye device, preparing them to conduct the associated activity in which they revise, prototype and evaluate their device designs made tangible with a 3D printer.
Learn about telegraphy and how to make your own telegraph key in the morse code demo.
In this hands on, exploratory lesson of waves, students will learn about longitudinal and transverse waves. Through mathematical reasoning, students will describe relationships between aspects of waves and a wave’s relative amount of energy. Students will use questioning skills to push the lesson along and facilitate engagement and discovery. The use of hands on models will help the students to discover relationships and characteristics of waves and go on to create their own models. Students will be able to...identify sound waves as longitudinal waves that travel through a mediumrecognize the dB levels of everyday soundsunderstand energy causes the vibrations that allow the sound waves to travel.
