good morning to all my dear friends , mam and teachers.i am priya from class 9.today i will present a speech on the topic of inventors and inventions in front of all of you.

we all learn in our school , collage and universities.the teachers teachers by following rules but rules are made by inventors.they may invent any thing but we never appreciate until the invention is useful to us.

inventors never depend on others.they try to think something very different from others.so we should appreciate their inventions.
