Experiment Kit eXperTeenies – Air

Investigating the Properties and Effects of Air at Experiment Stations

Grade level: Grades 5–7
Learning format: Station-based learning using the expert method
Use: Student experiments on respiratory gases, air pressure, air resistance, pneumatics, sound, combustion and other scientific phenomena related to air

With the Experiment Kit eXperTeenies – Air, students investigate different properties and effects of air through problem-based experiments. Short comics featuring Cory and Nelson introduce familiar everyday situations and provide the starting point for students to develop their own scientific questions and approaches to solving them.

The experiments combine a range of scientific and technical topics. Students investigate respiratory gases, air resistance, air pressure and pneumatics. Further activities cover the generation and transmission of sound, electrical circuits, combustion and magnetism.

The activities are organised into five learning stations. At each station, one student takes on the role of station expert. Using the corresponding station booklet, the expert supports the research team with selecting materials, setting up and carrying out the experiment, and answering safety-related questions. When the group moves to the next station, the expert becomes a researcher again.

In addition to scientific knowledge, this approach promotes teamwork, responsibility and independent scientific investigation. The tasks and worksheets provide different levels of support and can be copied for use by students.

Each station includes its own booklet with subject-specific information, practical tips and detailed illustrations of the experimental setups. A teacher's guide complements the concept with methodological guidance, information on the individual stations, materials and experiment descriptions.

Using a breathing regulator, the students test the introduction of oxygen and carbon dioxide into the detection solutions in two separate setups. In addition to the development of competence in measuring and the safe handling of chemicals, the test setups are designed in such a way that the detection reactions themselves can be dealt with intensively. Because it is important to find out which of the three available substances is suitable for detecting carbon dioxide.


The students have the task of ensuring safe transport for a memory card using a missile. They have materials at their disposal that should be used in a suitable way. During construction and testing, they learn about fundamental (technical and bionic) relationships between the paper surface used and the speed of fall, as well as the influence of weight and the flight of stabilizing and braking elements.


The students find out how a liquid-covered key can be dried out in a tub using air pressure. With the help of tea lights, the surrounding air is first heated and expanded. Putting a cup over the tealights makes them go out and the air cools down again. The liquid initially in the tub is pressed into the cup when the air pressure equalizes, so that the candles are lifted like in an elevator.


The students have to retrieve an object from a liquid-filled tub. A balloon and pump (syringe) are available for this purpose. You will learn how the pressure exerted by compressed air can be transmitted as a force and mechanical work can be performed in the process.


In the course of various partial constructions, the students examine the generation, propagation and transmission of sound. The aim is to set the grains on a membrane in motion with the help of a tambourine. Principles of soundproofing also come into play.


In an experimental setup with a buzzer that can be activated at the same time as a lamp, the aim is to find out which signal arrives at the receiver the fastest. Measurement methods and limitations are also examined.


The switching elements are to be arranged on a wooden board and interconnected in such a way that a lamp is activated at the same time as a buzzer. The students deal intensively with the arrangements of series and parallel circuits and apply them sensibly.


In the course of safely dealing with the fire triangle, the students research the requirements for the burning process and various extinguishing options. A candle staircase is also used, which behaves differently when oxygen is removed than when carbon dioxide is added.


The students set up a controlled chain reaction, at the end of which a tea light should be mechanically extinguished. The safe handling of fire (tea light and sparkler) is promoted as well as the structured and planned development of a reaction system.


A disc magnet is used to get a key out of a tub filled with liquid. The students learn about the principle of magnetic interaction and can try out ferromagnetism.
