Product Information


Discover the secrets of sound and answer questions like, "How do things make sound?", "What can sound do?", and "How can we send messages using sound?" with the Science Unlocked Wonder level curriculum kit, That's a Sound Idea: Sound, Vibration, and Communication!

In this kit, students will study the connection between sound and vibration, and they'll use their new knowledge to solve a communication problem. They can turn up the volume with activities like moving a ball with sound, making pepper jump, making some waves in water, and building a set of string phones. That's a Sound Idea comes with a full-color Student Curriculum Workbook and a detailed Teacher Guide. It is a phenomenon-based approach, designed to fully engage students in the topic of sound. Through a series of experiments, students will gain an understanding of how sound is caused by vibration, how vibration is caused by sound, and how sound can be used to communicate over a distance. This Wonder level kit will provide over 6 hours of learning, introducing your student to many foundational physics concepts.

The student will engage in these exciting activities:

  1. Use the sound of a tuning fork to move a ball
  2. Push pepper around with just sound
  3. Create a musical instrument from simple items
  4. Design the best set of string cups to help you whisper across a room
Use That's a Sound Idea to answer questions such as:
  • What is sound?
  • How do vibrations move through air and water?
  • How do musical instruments work?
  • What's the best material for sound to travel through?

Our Sound Idea kit is a part of the Science Unlocked Wonder series and is recommended for grades K-2.
