Students kit Sound and tone


This kit can be used in lessons covering physical and technical subjects as well as music and languages in grades 2 to 4.
The kit is especially suitable for learning in groups at specific workstations but can be used for any other type of lesson too.
The experiments focus on the phenomenon of sound: how sounds and noises are produced, that they are vibrations, that they can be transmitted and amplified, and what determines their pitch and volume.
No special material preparation is required, other than providing a CD player (1 CD is included).
The materials are suitable for all teaching formats but are especially well-suited for station-based learning in pairs.
With the included sound CD, children can match, recognize, and name sounds, distinguish sound twins, and reenact a sound story.  
Needed in addition: CD player

experiments
  • 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 (!).
