In a statement, the council rationalized the reduction by stating they wanted to reduce the content load on students in light of the Covid-19 pandemic. On June 1, India cut a slew of foundational topics from tenth grade textbooks, including the periodic table of elements, Darwin’s theory of evolution, the Pythagorean theorem, sources of energy, sustainable management of natural resources and contribution of agriculture to the national economy, among others. These changes effectively block a major swath of Indian students from exposure to evolution through textbooks, because tenth grade is the last year mandatory science classes are offered in Indian schools.
I think you could make an argument of combining the essentials of physics and chemistry into a single year long course but that would include teaching the conservation of energy, periodic table and so on.
But I disagree that people don’t use apply these subjects in your life. I think it’s pretty necessary to be able to estimate distance or be able to engineer repairs at home without having to call a professional or order brand new goods, or for chemistry, be able to clean your home without accidentally making a bomb.
