Professor: “Hello, children! My name is Elfriede von Knatterberg and I’m a scientist. Perhaps we already know each other from a previous film. I’m very pleased to discover the world with you today because I’m interested in everything around me and love finding out how things work. Do you love it, too? How do we actually find out how things are made around us? We see with our eyes, feel with our skin, smell with our nose, taste with our tongue and hear with our ears. These are our senses“. With the eyes we see whether it is light or dark, whether something is multicoloured or just one colour, big, small, thick or thin. Our sense of sight also helps us to determine which way we can go without colliding with someone, where obstacles are or which place is still free.
