Experimental sets for basic science lessons in primary school

In cooperation with committed local primary school teachers, XLAB has designed experimental sets on five different topics (see below). With these boxes, you can carry out a multitude of fascinating experiments during your school lessons. The boxes cover class sizes of up to 30 children. They include cards to initiate learning processes at various stations, as well as copy templates to print out worksheets. Thus, they allow you to realize science lessons in a comfortable and uncomplicated way.
The boxes can be borrowed by interested teachers directly from the XLAB. It is possible to borrow the boxes on a weekly basis. In order to cover the expenses for material and usage, we charge a usage fee as follows:

1 week  10 Euro,
4 weeks 30 Euro.

Please note: The experimental box ´Öffnet externen Link im neuen FensterChemistry in kindergarten` is also suitable for the first primary school classes.

The sun, the moon, and the stars

This set contains experimental material for up to 30 children and covers the following five topics:

•    constellations,
•    compass directions,
•    light and shadow,
•    day and night,
•    our moon.

The children should be able to read and write in order to carry out the experiments as independently as possible.

The senses: light and vision

The light and the eye

This box offers material for up to 30 children. The experiments start with identifying light as stimulus for the eye, followed by mostly independent experimenting on individual aspects of vision (reading and writing skills required!):

•    spatial vision,
•    the eye and the brain,
•    (external) composition of the eye,
•    the blind spot (internal composition of the eye),
•    resolving capacity of the eye,
•    vision testing.

The senses: sound and hearing

The set provides material for up to 30 children. They will identify sounds in form of sound waves of various amplitudes and frequency. Moreover, they explore the distribution of sound waves and their reception by the ear. For a deeper understanding, experiments on stereo hearing, distribution of sound in air or water, and hearing tests can be realized.


This box includes twelve experiments on the following topics:

•    salt and water (solubility, buoyancy of bodies, (boiling) temperature),
•    soap and water (surface tension),
•    dirt and water (sedimentation and adsorption capacity of activated carbon)

Limestone fossils

What´s that stone, what´s that fossil, and how were they formed? Based on eleven experiments, the children can find an answer to their questions on fossils and limestone (e.g. detection of lime and of carbon dioxide, making of ´fossils` and of sedimentary rocks). A collection of mainly local limestone fossils will help identifying their own findings.
