Imagine you are participating in an air purification experiment, where it is essential to understand the composition of different gases present in the atmosphere for the project's success. The air around us is a mixture of various gases, with the majority being nitrogen (N2), followed by oxygen (O2), and a small amount of carbon dioxide (CO2). When conducting a purification experiment, it is important to know not only the percentage composition of these gases but also how they interact and what happens if we alter this composition. Based on your knowledge, answer the following questions: 1) What are the approximate percentages of nitrogen, oxygen, and carbon dioxide in the standard atmosphere and what is the function of each of these gases for biological and environmental processes? 2) Considering that carbon dioxide is an atmospheric pollutant that contributes to global warming, what would be the effect on the purification experiment if we increased the percentage of this gas in the purified mixture?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.
