In this unit, students develop ideas related to how sounds are produced, how they travel through media, and how they affect objects at a distance. Their investigations are motivated by trying to account for a perplexing anchoring phenomenon — a truck is playing loud music in a parking lot and the windows of a building across the parking lot visibly shake in response to the music.

They make observations of sound sources to revisit the K–5 idea that objects vibrate when they make sounds. They figure out that patterns of differences in those vibrations are tied to differences in characteristics of the sounds being made. They gather data on how objects vibrate when making different sounds to characterize how a vibrating object’s motion is tied to the loudness and pitch of the sounds they make. Students also conduct experiments to support the idea that sound needs matter to travel through, and they will use models and simulations to explain how sound travels through matter at the particle level.

In this simple exploration, a coiled phone cord slows the motion of a wave so you can see how a single pulse travels and what happens when two traveling wave pulses meet in the middle.

Ralph Baer’s family fled Nazi Germany for the US when he was a child. Using wartime technology, Baer thought outside the box and transformed the television into a vehicle for gaming. His invention was the birth of the first home console, the Odyssey, a precursor to the Atari gaming system. The resource includes a lesson plan/book card, a design challenge, and copy of a design thinking journal that provide guidance on using the book to inspire students' curiosity for design thinking. Maker Challenges: (1) Think outside the box. What’s something you use everyday, but not for its “intended” purpose? Examples: A broom to clean the snow off your car windshield, a trash bag as a sled. Now, think of a problem you might have at school, home, et al. Invent an item that would solve this problem. (2) Let’s think outside the box! Design the latest and greatest technology for kids to hit the market! Make it the *most* fun anyone has ever had. You may NOT use anything on the market - any technology currently on the market is off limits. Use your imagination, do not put limitations on it, and be as creative as you can. (3) Use household items to create a prototype of your new invention.

CK-12 Physical Science Concepts covers the study of physical science for middle school students. The 5 chapters provide an introduction to physical science, matter, states of matter, chemical interactions and bonds, chemical reactions, motion and forces, and the types and characteristics of energy.

Students are introduced to sound energy concepts and how engineers use sound energy. Through hands-on activities and demonstrations, students examine how we know sound exists by listening to and seeing sound waves. They learn to describe sound in terms of its pitch, volume and frequency. They explore how sound waves move through liquids, solids and gases. They also identify the different pitches and frequencies, and create high- and low-pitch sound waves.

This simulation helps students feel what happens to the sound when you adjust the loudness and pitch. It asks students “What do you feel happen when you touch the speaker?” and “What do you hear happen to the sound?” This is used in Lesson 3 of Unit 8.2 of the OpenSciEd curriculum.

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.

Learn how to make waves of all different shapes by adding up sines or cosines. Make waves in space and time and measure their wavelengths and periods. See how changing the amplitudes of different harmonics changes the waves. Compare different mathematical expressions for your waves.

The example of rabbits and foxes was introduced in the task (8-F Foxes and Rabbits) to illustrate two functions of time given in a table. We are now in a position to actually model the data given previously with trigonometric functions and investigate the behavior of this predator-prey situation.

The example of rabbits and foxes was introduced in 8-F Foxes and Rabbits to illustrate two functions of time given in a table. The same situation was used in F-TF Foxes and Rabbits 2 to find trigonometric functions modeling the data in the table. The previous situation was somewhat unrealistic since we were able to find functions that fit the data perfectly. In this task, on the other hand, we do some legitimate modelling, in that we come up with functions that approximate the data well, but do not perfectly match, the given data.

During a scavenger hunt and an art project, students learn how to use a handheld GPS receiver for personal navigation. Teachers can request assistance from the Institute of Navigation to find nearby members with experience in using GPS and in locating receivers to use.

Richard grew up in Kenya as a Maasai boy, herding his family’s cattle, which represented their wealth and livelihood. Richard’s challenge was to protect their cattle from the lions who prowled the night just outside the barrier of acacia branches that surrounded the farm’s boma, or stockade. Though not well-educated, 12-year-old Richard loved tinkering with electronics. Using salvaged components, spending $10, he surrounded the boma with blinking lights, and the system works; it keeps lions away. His invention, Lion Lights, is now used in Africa, Asia, and South America to protect farm animals from predators. The resource includes a lesson plan/book card, a design challenge, and copy of a design thinking journal that provide guidance on using the book to inspire students' curiosity for design thinking. Maker Challenge: Your challenge is to use broken or old technology and other available resources to create a prototype that can be used to protect your home.
