Research the Topic
After you have established the problem you are trying to solve, you should gather some background information about the topic. It is important to be as educated as possible in your area of interest so that you understand the basic science terminology, are aware of other experiments that have been conducted, and can form a good hypothesis. Remember, that a hypothesis is an “educated” guess and you can’t form an “educated” guess without some education! To this end, listed below by science discipline are different topics that have been thoroughly researched by sixth grade science students. Feel free to use the information listed on this web site as a reliable source of information.

Topics by Discipline

The table below breaks down student research by discipline. Click on a topic below the discipline title for more information.
  • Physics - the study of matter and energy, and the interactions between the two
  • Biology - the study of living things
  • Chemistry - the study of the composition, structure, properties, and reactions of matter, especially of atoms and molecules.
  • Engineering - the application of scientific and mathematical principles to practical ends such as the design, manufacture, and operation of structures, machines, processes, and systems.
  • Environmental - the integration of physical and biological sciences to study the environment and find solutions to environmental problems
  • Geology - the study of solid Earth, the rocks of which it is composed, and the processes by which they change
  • Medicine - the applied science or practice of the diagnosis, treatment, and prevention of disease
