Kraul Listening Box

Kraul Listening Box – Acoustic Experiments | Kids STEM Science
The Kraul Listening Box introduces children to the wonders of sound through hands-on experiments that are simple and deeply engaging. This experimental kit includes a stethoscope, tuning fork, balloons, elastics, cardboard tubes and string to make a string telephone.
With this kit, children can explore sound not only through hearing, but also visually and through touch. Use the stethoscope to listen to your heartbeat or the funny gurgling of your tummy. Watch sound waves being created using the tuning fork in a bowl of water, and use balloons to amplify sounds by making them into speakers. Make a string telephone to investigate how sound travels through string and air. 
This toy supports auditory sensory play and encourages the transforming schema as children change what they hear using different materials and instruments. It is ideal for home educators, schools, or curious children who love to ask questions and find answers through experimentation.
