Knowledge in earth science is very vital in nation building. Almost everything we do each day is connected in some way to Earth: to its land, oceans, atmosphere, plants, and animals. The food we eat, the water we drink, our homes and offices, the clothes we wear, the energy we use, and the air we breathe are all grown in, taken from, surround, or move through the planet. According to American Geological Institute (AGI) Foundation, by 2025, eight billion people will live on Earth. This number of people will undoubtedly continue extracting resources to maintain a high quality of life. As we benefit from all the resources we get from the Earth, then we, as individuals and citizens, need to know more about our planet - its processes, its resources, and its environment. And only through Earth Science education can students understand and appreciate our complex planet. In this present time, the old and the young must join hands and help one another in the serious task of nation-building, the young to learn from the wisdom and experience of the elders, the elders to recognize the impatience of the youth. In contrast, not all young students are willing to cooperate in order to acquire the needed knowledge, attitudes and skills essential for a secure future. It is then a burgeoning task for the teacher to facilitate learning so that quality education will be acquired by the students. This paper will discuss the different challenges faced by the teacher in imparting knowledge about Earth Science in public secondary school, likewise it will also discuss the positive aspects in learning the subject.
