Physics
Heat conduction rods, 4 x metals
Set of four rods in steel, brass, aluminum and copper in the same holder. Each rod is equipped with a liquid crystal indicator that turns green at approx. 40 °C and where the green temperature indicator moves up the rod in step with heat conduction in the metal. Max. working temperature approx. 100 °C; after cooling the experiment can be repeated.

Miscellaneous
Heat radiation bottles
To demonstrate the importance of color for heating and cooling.
Fill with cold water and place near a strong light source, possibly in the sun. The increase in temperature over time shows the importance of the color for the absorption of radiant energy. Similarly, with warm water first – a light source is not necessary.

Biology
Human blood, microscope slide
The microslide shows a blood smear of human blood that has been fixed and stained so that the different blood cells can be clearly distinguished. The red blood cells appear red, while the white blood cells are seen in purple-blue shades with different sizes and nuclear types. The slide provides a clear insight into the composition of the blood and makes it possible to work with both the structure and function of the individual cell types.
