Fo 06 Digestion of starch and household sugar: Decomposition of molecules
 For extremely clever kids only: Explanation by bead models

You might understand what happens in your belly while the starch of pototoes is digested:
* Left: String at least 20 yellow beads on a thin brass wire. * Coil this string around a pencil.
* Explanation: Your stringing of yellow beads illustrated the connecting a great number of glucose molecules (T) in a growing potato.
More than 20 glucose molecules form one single starch molecule .T-T-T-T-T-T-T-T-T-T-T-T-T-T-T-T-T-T-T-T.
* Middle: Heat two yellow beads until they have soft spots, weld them and press them together.
* Explanation:  By chewing potato pieces for a long time without swallowing it each of the huge starch molecules decompose leaving a great number of "twin sugar" molecules (T-T).
* Right:  Household sugar (T-F) is made similar twin sugar molecules. Digesting this sugar by bees means  that each of its twin molecules decompose resulting in 2 molecules "single sugar ( T und F).
