Science fair zone

Water can be a great subject area for your science fair project. The physical, chemical, biological or social aspect of water in your life can be considered. The surface tension of water that is different temperatures, the capacity of household products to absorb water, the survival rate of plants being irrigated by different types of water and the ability of younger versus older family members to conserve water are just a few ideas worth investigating. If you are looking for a science fair idea, consider the role of water in your everyday life and you’re sure to come up with a fun and interesting topic.

Read the science fair tips below to help you on your way. There are many websites that can provide additional assistance. Listed below are some sites you might want to explore.

Super science fair project tips

Follow the guidelines or instructions you receive from your teacher. If a parent or other adult is going to help you with your project,share your teacher’s guidelines and instructions before you do anything else.

  1. Allow yourself enough time, don’t wait until the last minute to start your project.
  2. Take care to include enough content in your display, flashy displays without valid information will not impress many science fair judges.
  3. Select a project that is not too complex.
  4. Don’t change the project results to fit a hypothesis.
  5. Do the work yourself with only limited help from an adult.
  6. Be creative.
  7. Select a project suitable for your age, skills and knowledge.
  8. Have fun and learn something new.
  9. Use the scientific method.

The scientific method

Roger Bacon, (1214-1294) an English philosopher, is thought to be one of the earliest advocates of the scientific method, which simply stated is an orderly approach to acquiring knowledge in the natural sciences. The scientific method involves several steps:

  • Identifying a problem
  • Developing a hypothesis (an assumption made to be tested)
  • Deciding on a procedure to test the hypothesis
  • Collecting and analyzing the data
  • Formulating a conclusion
