Students kit Materials in everyday life


This kit contains equipment and resources for scientific experiments covering multiple disciplines to study various substances. An initial section allows experiments to be carried out on basic material properties.
A second allows experimentation on mixtures of substances and separation of mixtures.
In addition, it is also possible to study changes of state between solid, liquid and gaseous substances and material changes due to chemical reactions.
