TN Board Class 7 Science Syllabus

Instead of seeing education as reading and writing,introduce that into real.Just ask how? and why?.Let them take it apart. Whenever possible let take something of interest apart to better understand it.Encourage yourself to think like scientists. Science education is one of the most important subjects in schools because its relevance to students’ lives and the universally applicable problem solving and critical thinking skills.

Why should study science?

Because there are some reasons

  • Science prepares for future.
  • Science feeds a natural love for learning
  • Science opens doors to many disciplines

The class 7 Syllabus provided by the TN board gives the knowledge on matter around us,living world of plants and animals, light, heat,measurements etc.
