Section one:
Know about the frequency of breathing (K1-3)
Please count the rate of breathing for one minute in two circumstances:
- After running alone the aisle for one minute
- After sitting quietly on the chair (doing nothing)
Instructions: Let the students divided by two people for a group. If time permits, we can do both on them (one is counting the other one’s breathe, and then switch), if not we can do it one time).
Teaching points:
Inform students the meaning of respiration; let them feel that the frequency changes when we are having different intensity of activities.
Section two:
Know about the capacity of human lungs (K1-3)
Please blow the balloons in two different ways to see how big the balloon can be.
- Blowing lightly
- Blowing deeply (try as long as you can)
Instructions: Let students compare the balloon in different size, ask them why.
Teaching point: Inform students that different people has different lung capacity.
Section three:
Know about the gas exchange in inspiration (K4-6)
- Hold your breath, feel the respiration
- Infer and guess what happen in the process of your breath, the change of the air you breathe in and breathe out.
- Design an experiment to prove your theory.
i. Use a plastic bag to collect the fresh air—represent the air we breathe in
ii Use a straw to blow your breath in a balloon –collect the air we breathe out
iii Use a burning candle or crystal Ca(OH)⑵ to see the different phenomenon.
Teaching point: The oxygen become less in the meantime, the carbon dioxide increased in our in our breathe out air. When we breathe, we inhale oxygen and exhale carbon dioxide.
Section four (K1-6)
Know about how breath happens inside our body (illustrate the use of diaphragm)
- we could put a balloon into a bottle, cover its neck with that balloon
- We only need squeeze the bottle or recover it to change its inside air pressure.
- If we recover the plastic bottle, the space will enlarge, so the air pressure inside will become lower, then the balloon will grow. Vice versa, if we squeeze, the space will become smaller, the air pressure will rise, so the balloon will become leaked.
Teaching point: As the diaphragm contract and relax, breathing take place: pumping the carbon dioxide out of the lungs and pull the oxygen into the lungs.
Section five
Know about the structure and function of a lung (K3-6)
Use a lung model to show the basic structure of the human lungs
Teaching points:
Trachea
Right lung (upper lobe)
Right lung (middle lobe)
Lower lobe
Primary bronchus
Superior lobar bronchus
Interdisciplinary: By incorporating different subject matter, academic disciplines and multiple research methods, the connection between academic knowledge and the real life is tighten. Encouraging students to understand, solve problems with multiple thinking patterns.
Creative modeling: Deepen the idea of modeling, enable students learn by doing. The joy of teamwork and D.I.Y can also improve their performance and facilitating ‘knowledge enrichment and modeling skills enhancement’.
Enlighten education: Leading students from ‘Darkness to Light’ is our motto along with providing excellent opportunities about different subjects. Exciting and stimulated student’s interest in Mathematics, Physics, chemistry, biology (4 elements of science)
Curriculum modules and specific design

Model 2: Learning the respiration system
Math section: learn to compare and measure the weight and volume of materials, solid or liquid , enabling students to master the measuring methods.
Chemistry section: gas exchange in inspiration, cellular oxidation
Modeling section: Learning the respiration system by making the lung model with balloons and empty bottles.
Module 3: Learned the movement in digestion system
Math section: learn how to draw Statistical graph (curve diagram, Line graph, bar graph, Table chart histogram
Compare the different digest rate in three kinds of food (sugar, protein, fat), and draw
Chemistry section: Teacher can ask questions to teach the digestion of Starch & Sugar &Fat
l What is needed to digest starch?
l What Enzyme Helps Digest Carbohydrates?
