Fall Science Fair Project Hypotheses for You

Fall Science Fair Project Hypotheses

September is officially here and it is a great time of year to come up with ideas for your science fair projects. Fall is an interesting time to conduct earth science and biology science fair projects, as well as behavior projects. This week’s blog is going to focus on ideas for fall themed science fair project hypotheses. Feel free to use these ideas to help you come up with your own award winning science fair project.

Fall Biology Science Fair Project Hypotheses

  • Temperature impacts the heart rate of kids playing outside.
  • Temperature impacts the behavior of pets.
  • A plant’s chemistry changes in the fall.

  • Fall Earth Science Fair Project Hypotheses

  • Soil becomes more stable in the fall.
  • Rock formation become unstable in the fall.
  • Fall weather conditions can predict Springtime rock slide frequencies.

  • Fall Food Science Fair Project Hypotheses

  • Bacteria grows on food slower in the fall than in the summer.
  • People crave different types of foods in the fall than they do in the summer.
  • People relate the smell of certain foods to specific emotions.

  • Developing a Fall Themed Science Project Hypothesis

    If you want to learn the details of how to write a hypothesis, then look here…

    When you develop your fall themed science project hypothesis it is important that you focus the hypothesis on a specific question. Try to focus it enough so that only one experiment will be required to test your hypothesis. For more ideas on science fair projects I recommend Science Base. Use the information from this blog to come up with new ideas and projects.

      Dave, there actually is a sneezes science fair project called, UNDERCOVER SNEEZE. It investigates whether covering your mouth or not will prevent the spread of germs.

      Some of the most commonly searched terms on my site relate to how germs are spread through coughs and sneezes, but I guess that’s a little impractical as a science project. However, another is getting the hard-boiled egg into a bottle, that’s a perennial favorite, as too is explaining what happens to the boiling point and freezing point of water (any solvent) when one adds a solute (such as table salt or sugar) and what effect that has on cooking times and slippery winter roads.
