Take a look at an organized physics course. The 34-section electronic textbook covers material in AP® Physics 1 and 2. Teachers use the text to supplement lectures and have the class work through the labs. Each section contains multiple...

How does this sound? It's a rockin' video starring two teenage girls talking about music, hearing, and the ear. Listeners hear that the ear does not only gather sound waves, but also helps us maintain balance. They also will get an...

Curious scholars make like Curious George and use their five senses to identify mystery objects. After a brief discussion, learners watch an engaging Curious George video in preparation for an activity. Scholars visit three tables that...

How loud was that? Individuals build wheels displaying different sounds. Then, learners use the wheels to find the number of decibels the sound creates and how long they could withstand the sound before potential hearing damage.

Watch augmented reality bring classrooms to life. Scholars work in groups to design, build, and market a new pair of headphones meant for children under three. They use an augmented reality app to show their headphones in action as they...

With all its folds and inner workings, the ear is an extraordinary thing. Take a tour through the anatomy of the ear to get a glimpse of how all the parts works Learners watch as an animation demonstrates how humans hear. The...

One of the few body parts that self-cleans, ears contain three sections and many different parts. An interactive displays each section with a description of the importance of every part. Users discover how hearing and balance both rely...

Young scientists explore hearing through multiple experiments, demonstrations, and activities. They focus on the changes in hearing over a lifetime, how we can determine where a sound is coming from, and the ability to filter noises.

What do shapes sound like? Scholars learn about the frequencies of pure tones created by vibrations of shapes. The video first considers the case of string, then moves on to two dimensions. It touches upon Fourier series and a question...

Your sense of hearing depends upon tiny hairs deep inside your ear and if you lose these hairs, you lose your hearing. Here, groups explore hearing through the decibel measurement of common sounds. As a class, participants discuss...

Why do dissonant noise cause a physical reaction of fear in humans? The video explains why some things sound scary and how we evolved to be more afraid of sounds than sights. It details how people constantly live in the past and how this...

Humans can sense about 10,000 different odors. Young scientists explore how humans interpret the world around them using their senses. The instructor reminds learners of action potentials and the nervous system and then focuses on three...

If a tree falls in the forest and no person is around, does it still make a sound? Students view a short video segment to determine sound and decibel levels of various objects, including the loudest and quietest possible sounds humans...

In a comprehensive unit of activities, learners explore the five senses. Youngsters discover the many different body parts and their functions that allow humans to have sense of sight, touch, smell, taste, and hearing. The best way to...

Tell students to listen up and watch this video to help them practice being an effective listener in the classroom. Colorful animations provide students with key tips to start practicing.

Ironically, no sound it heard in this video, only computer animation and text. It details how sound waves travel into the ear canal and cause the eardrum to vibrate. The inner ear bones and cochlear hairs are shown in motion. This...

If you are experiencing hearing loss, you may have to see someone like Drew, a hearing aid fitter dispenser. He evaluates patients who need hearing aids and walks viewers through the process of getting fitted.

Hear ye, hear ye! Here is a video that comes with an article to read, an interactive quiz, hands-on activities, and worksheets, all about the ear! Chloe and the Nurb take viewers on a virtual tour of the ear, discussing its structure and...

Investigate soft, loud, and dangerous sounds. Little ones put a check next to the sounds that are loud, an X next to ones that are soft, and circle the ones that would require protective ear wear. Tip: Get out a tape player or computer...

Third and fourth graders should enjoy this easy-to-implement activity involving a straw, and bottles filled with water. Learners manipulate the end of a straw in a way that results in a sound being made when it's blown. There is also an...

Students identify the five senses. In this biology lesson, students participate in an experiment and use their five senses to identify various substances.

Focus on the /ea/ and /ear/ sounds. Learners complete three sentences by adding the appropriate ea word from a word bank, re-writing each sentence. Then, they read an excerpt from Little Red Riding Hood and find all the words with...

Hre is an ESL and printing practice worksheet. Learners trace six examples of the word "ear" before forming their own words on the primary lines. They color the pictures of the ears.

Third graders use logic and knowledge of mathematics facts to solve problems. They see that pigments can be broken down into separate colors. Pupils recognize the capacity of water to move upward and measure the height water travels up...
