Technical specifications

Size of kit: 540 x 450 x 150 mm

• 1 - Assigning sounds

  experiment "Assigning sounds"

  The students match the different sounds on a sound CD.

  
  
• 2 - Recognizing and naming sounds

  experiment "Recognizing and naming sounds"

  Here, students match sounds and sound-naming verbs.

  
  
• 3 - The rubber ring zither

  experiment "The rubber ring zither"

  A rubber ring zither can be used to explore the relationships between "string" length, gauge and tension on the one hand and "tone" pitch on the other.

  
  
• 4 - The Pan Flute

  experiment "The Pan Flute"

  The students use the test tubes as a pan flute.

  
  
• 5 - The bell

  experiment "The bell"

  The sound of a vibrating body (here a rubber ring) can be changed by a resonating body, although this is initially only noticeable in the volume.

  
  
• 6 - Why do we have two ears

  experiment "Why do we have two ears"

  In this experiment, the soft tapping sounds on a soft tube are clearly perceived.

  
  
• 7 - Through the cord into the ear

  experiment "Through the cord into the ear"

  A string transmits sound stronger and faster than air, but only when it is taut. The students can observe this phenomenon with a can telephone.

  
  
• 8 - The Stethoscope

  experiment "The Stethoscope"

  The students can listen to heart sounds with the help of a stethoscope.

  
  
• 9 - Hearing through tubes

  experiment "Hearing through tubes"

  Children know from experience from swimming that you can hear well under water, but here the comparison is possible: you can hear the struck tuning fork vibrating in the water without a tube - using only the air as a transmitter - and through the tube.

  
  
• 10 - Sound twins

  experiment "Sound twins"

  The students assign sound twins.

  
  
• 11 - Playing a sound story

  experiment "Playing a sound story"

  The students assign a sequence of sounds to a storyline.

  
  
• 12 - Mysterious tickling - The tuning fork in water - Tuning fork ball games

  experiment "Mysterious tickling - The tuning fork in water - Tuning fork ball games"

  The students use a tuning fork and can establish a connection between vibrations and sound through various experiments.

  
  
• 13 - Singing knitting needles and steel strips

  experiment "Singing knitting needles and steel strips"

  With these experiments, students can explore the connection between vibrations and sounds in a playful way.

  
  
• 14 - We are putting together a carillon

  experiment "We are putting together a carillon"

  Students* assemble a carillon. The learning outcome of assembling and trying out the glockenspiel is the following insights: Of a set of plates, the longest sounds the lowest and the shortest sounds the highest.

  
  
• 15 - The "thumb piano"

  experiment "The "thumb piano""

  On the "thumb piano", the relationships between the length of the vibrating steel strip and the pitch can be tested quite "naturally".

  
  
• 16 - Sometimes quiet, sometimes loud

  experiment "Sometimes quiet, sometimes loud"

  With the combination music box / sound box you can experience how strongly the sound is amplified by a resonating body.

  
  
• 17 - The mysterious body

  experiment "The mysterious body"

  A corpus determines not only the volume, but also the sound of an instrument quite significantly, as it resonates in its own way.

  
  
• 18 - The cackle can

  experiment "The cackle can"

  The can does not "cackle", it only makes the vibrations on the string audible. To do this, it must be made to vibrate.

  
  
• 19 - Ways of sound

  experiment "Ways of sound"

  A soft sound is audible. How does it reach the ear? The children soon find out that it must be the air. They may also have heard that you can't hear anything where there is no air (in space) - or conversely, that you can hear very well under water.

  
  
• 20 - The magic finger

  experiment "The magic finger"

  On the level of physics, this is about the transmission of sound - via the string held taut and the finger bones. Beyond that, however, there is much else to discover. For example, one can determine the different distance of the tuning forks and also the proximity to one of the two ears. Also, the sound of the tuning forks gets a completely different character when it is not conducted into the ear via the air, but via string and fingers (!).
