Fats in nutrition

Information sheet:
Fat in excessive quantities can harm human health. Therefore, it is important to know which fats and how much are important and beneficial for human nutrition.

The information sheet answers the following questions:
· What do we need fats for?
· What are fats made of and what types are there?
· What are the health consequences of eating too much fat?
· What are hidden fats and what foods contain them?
· How can I consciously eat a healthy diet?

Information and ideas:
The topics of carbohydrates and proteins can be rehashed by the students in a similar manner with respect to their importance for human nutrition.

C3 How does human digestion break down fats? (worksheet 2)

Worksheet for subject teaching in English:
For the student experimentation instructions of the same name. Methodology tool: film strip developed by Josef Leisen and Heinz Klippert.


Note: This worksheet has been developed especially for subject teaching in English and for language-sensitive subject teaching. It uses the film strip methodology tool developed by Josef Leisen and Heinz Klippert. The film strip supports coherent speaking and the correct chronological and content-related sequence of actions or events.
Students whose native language is not English and who do not have strong English skills receive support and training in understanding the technical vocabulary. They work with the specialized vocabulary and in this way acquire the ability to communicate about specific subjects.

Saponification and digestion of fat

Interactive chemical equations:
The chemical equations for the alkaline saponification of fat and the breakdown of fat in human digestion can be developed interactively.

Word and reaction equations are shown for the alkaline saponification of fat; only the word equation is shown for the breakdown of fat in human digestion.
The equations can be developed in two ways:
· Entire equation at once
· Individually by educts and products.

pH-values in the body and in everyday products

Interactive graphic:
A pH scale can be labeled interactively with typical sample values from the areas of "human body" and "everyday products".

The pH scale covers the entire range from 0 to 14 and shows that negative pH values are also possible.

The scale can be labeled individually or as a whole.

Absorption of fat in the small intestine

Interactive graphic:
The process of fat absorption in the small intestine can be developed interactively.

The graphic shows all substances involved in the absorption of fat in the small intestine (with labels) and visualizes the process sequence using arrows. The entire process is divided into five steps, which can be displayed in succession. It is always possible to jump back to the previous step.

C3 How does human digestion break down fats? (teacher instructions)

Experimentation instructions for Experimento | 10+:
Background information on the content and practical information on conducting the experiment "How does human digestion break down fats? - Saponification of edible oil". This experiment comprises two subexperiments.


These simple experiments for the emulsification and saponification of fats are well suited as an introduction to the topic of digestion and metabolism in the human body. Starting from the experiment that merely demonstrates that fats can be split into fatty acids, the topic must then be related to human digestion. These teacher instructions provide information and suggestions for this. The materials and apparatus supplied are sufficient to allow eight groups of students to conduct the experiments simultaneously.

The experiment comprises two subexperiments:

· We emulsify oil
· Saponification of edible oil

Notes:
· Observe the safety information in the instructions as well as the applicable safety guidelines for your school.
· All materials mentioned in the instructions will have to be purchased directly from commercial sources.

The micelle

Interactive schematic diagram:
The components of a micelle can be labeled interactively.

The graphic shows the structure of a lipid micelle, how the micelle is formed in the human body during the fat digestion process, and its components: bile salts, monoglyceride, cholesterol, phospholipids, apolar lipids, and long-chain fatty acids.

The graphic can be labeled individually or as a whole.
