When observing a beautiful sunset, we notice that the sky takes on an orange hue, and this can be explained by the properties of light scattering. However, if we analyze the phenomenon based on the composition of the air, we can also understand how the presence of certain gases affects how we see sunlight at the end of the day. The air we breathe is a mixture of gases, with nitrogen and oxygen being the most abundant, closely followed by carbon dioxide. Based on this context, answer: (1) What is the approximate percentage composition of atmospheric air in terms of nitrogen, oxygen, and carbon dioxide? (2) Discuss briefly how air pollution, including the presence of aerosols and other contaminants, can alter the way sunlight is scattered, impacting the air quality we breathe and our visual perception.Answer sheet:

Imagine that you and your family went camping near a lake for the weekend. Looking at the lake, you remembered that the water there could have passed through many places and been in different forms. Think about the sun heating the lake water, it turning into vapor and rising to the sky, the clouds loaded with vapor, and then the rain falling back into the lake. Describe what happens to the water during this journey, from the lake evaporated by the sun to the rain falling back into the lake, and explain the role of the sun in the water cycle.

Imagine that our body is like a very large city, and the blood needs to reach all parts of this city to deliver oxygen and nutrients. The circulatory system is like the road network of this city, with the heart being the central pumping station and the veins and arteries being the avenues and streets through which the blood travels. Based on what you have learned about the circulatory system, explain how the heart, veins, and arteries work together to circulate blood through the body and mention at least one important function of each of these components.
