General description

The model should show the students what a head louse looks like and how small it is in real life. For that reason, there should be two head lice on one sheet: a head louse in the original size (3.5 mm) and an enlarged one, as accurate and big as possible.

How to use this exercise?

The students get to know different endoparasites and ectoparasites.

Head lice are very common, but many students have never seen head lice themselves. With the enlarged model these parasites are to be illustrated and at the same time the real size is shown.

The model should be printed once for the entire class.

Learning Specifications

How can the model be used in class?

  • Brainstorming session: The students are asked which parasites they know and which of them occur in our country.
  • After that the students comment on which parasites they have ever seen themselves and whether they could describe the exact look.
  • Now it’s about the head lice and their size. Students who have already seen head lice should sketch these on the board and indicate the size.
  • The model is then output so that students can see and touch the head lice in detail and see the real size.

What benefits can its use have?

  • Head lice are very common and therefore they are a very important subject in school for medical assistants. The lice are very small. A 3D model can help students get an accurate idea of the size relationships.
  • The enlarged model shows the structure and appearance of a head louse. In 3D, this is much clearer compared to an illustration in a school-book.
  • With the smaller model in full-scale, the students see the head lice in their original size. This is important, because head lice must be recognized by medical staff.

Can it be used in other subjects?

Medical assistants, medicine, Vet assistants.
