C2 Carbohydrates as providers of energy for metabolism (teacher instructions)

Experimentation instructions for Experimento | 10+:
Background information on the content and practical information on conducting the experiment "Carbohydrates as providers of energy for metabolism - Starch and sugar". This experiment comprises two subexperiments.


This experiment is an introductory experiment to the overall topic of digestion and metabolism in the human body. It is suitable as a qualitative introduction to the topic of digestion for the age group up to 16 years. However, further study of the topic of metabolism necessitates considerable basic knowledge of organic chemistry and biochemistry, which cannot be assumed until the age group 16+ or acquired then. The materials supplied allow eight groups of students to conduct the experiments simultaneously.

The experiment comprises two subexperiments:
· Potatoes contain starch
· Hydrolysis of starch

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.

C1 We burn sugar (student instructions)

Experimentation instructions for Experimento | 10+:
Detailed instructions and questions for students on conducting the experiment "We burn sugar - Cellular respiration and respiratory chain". This experiment comprises three subexperiments.


The experiment comprises three subexperiments:
· Sugar can be burned
· Verification of reaction products in the air that is breathed: Substance A
· Verification of reaction products in the air that is breathed: Substance B

For each subexperiment, the students are first provided with an overview of the materials to be used and safety information. This overview is followed by the detailed, step-by-step instructions for conducting the experiment. Afterwards, the students are asked to note their observations. Specific questions are used to guide the students as they analyze the results of the experiments. At the end, the students are asked probing questions related to the experiment (an answer sheet is available for teachers).

Notes:
· Observe the safety information in the instructions as well as the applicable safety guidelines for your school and discuss it with your students.
· This student instruction is also available in Word format (doc-file).

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.
