Teaching Science can only be successful if we are able to answer the challenges of the 21st century. Teaching Physics, Chemistry and Biology with the traditional methods is unintelligible and considered unnecessary for most students. This situation needs to be changed. Students can only develop their abilities and skills to the full extent and can only deepen their knowledge when they are surrounded by an atmosphere which is motivating and encouraging for their personality. The establishment of this motivating atmosphere is the task of the teacher mainly joining up with parents. Out of the wide range of innovative options, in this article I deal with the teaching and learning of Science through project works at school. We can give students, for instance, more complex project works where besides Physics they have to go into the matter of Biology or other Science subjects. While they are searching for information, they use the Internet and at the end they produce a presentation and at the same time they develop their informative-communicative skills. So all things considered, students are affected positively from more sides while working on the project work. At first, I survey the recent situation of teaching Science then I present a particular project work in which we can examine thermoacoustic phenomena with cheap and easy-to-prepare tools at school.
