Teaching material for experiments on air

eXperTeenies - Experiment set for your MINT lessons

Comics tell stories. The storytelling approach highly excite students since natural science topics get a personal meaning. The experience of every day life phenomena is the aim of our new experiment kit. Each experiment ap‧proach is accompanied by a short comic story with the main characters Cory & Nelson. The first kit includes more than 15 experiments linked to the topic “Air”.
Experiments at stations do not lead into a defined direction:
there is no right or wrong.
Each learner receives the support she or he needs.
The students are designated as expert for a certain station. This way they are in charge of his or her scientist team.
The “station expert” supports his / her team while realizing the experiment: either with posed questions, selection of material, the construction of the experiment or safety precaution.
The expert alternates at the next station.
This way everyone can participate in experimenting, find out correlations that lead to the answer of individual questions.
While experimenting the teacher is relieved through the expert and each student is individually supported.
The self-confidence and sense of responsibility is strengthenend due to the exchange of the expert function.
While teaching natural science the exchange between the stu‧dent also enforces teamwork and sense for language.

  • 1 - Evidence of breathing gas (Station 1)

    experiment "Evidence of breathing gas (Station 1)"

    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.

  • 2 - Air resistance (Station 2)

    experiment "Air resistance (Station 2)"

    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.

  • 3 - Candle lift (Station 3)

    experiment "Candle lift (Station 3)"

    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.

  • 4 - Magnetic adhesive force (Station 3)

    experiment "Magnetic adhesive force (Station 3)"

    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.

  • 5 - Pneumatics (Station 3)

    experiment "Pneumatics (Station 3)"

    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.

  • 6 - Sound transmission (Station 4)

    experiment "Sound transmission (Station 4)"

    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.

  • 7 - Speed ​​of Sound (Station 4)

    experiment "Speed ​​of Sound (Station 4)"

    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.

  • 8 - Parallel connection (station 4)

    experiment "Parallel connection (station 4)"

    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.

  • 9 - Candle Staircase (Station 5)

    experiment "Candle Staircase (Station 5)"

    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.

  • 10 - Chain Reaction (Station 5)

    experiment "Chain Reaction (Station 5)"

    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.
