Introduction to 2nd Grade Science Fair Projects

2nd graders tend to be very curious. Apply that natural inquisitiveness to the science fair project. Look for a natural phenomenon that interests the student and have him or her ask questions about it. Expect to help a 2nd grade student plan the project and offer guidance with a report or poster. While it's always nice to apply the scientific method, it's usually okay for 2nd grade students to make models or perform demonstrations that illustrate scientific concepts.

2nd Grade Science Fair Project Ideas

  • What factors affect the rate at which foods spoil? You can test heat, light, humidity.

     

  • Do all students take the same size steps (have the same stride)? Measure feet and strides and see if there seems to be a connection.

     

  • Do most students have the same favorite color?

     

  • Take a group of objects and categorize them. Explain how the categories were selected.

     

  • Do all students in the class have the same size hands and feet as each other? Trace outlines of hands and feet and compare them. Do taller students have larger hands/feet or does height not seem to matter?

     

  • Are waterproof mascaras really waterproof? Put some mascara on a sheet of paper and rinse it with water. What happens? Do 8-hour lipsticks really keep their color that long?

     

  • Do clothes take the same length of time to dry if you add a dryer sheet or fabric softener to the load?

     

  • Put a pair of old socks over your shoes and go for a walk in a field or at a park. Remove the seeds that attach to the socks and try to figure out how they attach to animals and what the plants they come from might have in common.

     

  • Do frozen candles burn at the same rate as candles that were stored at room temperature?

     

  • Do all types of bread grow the same types of mold?

     

  • Collect insects. What types of insects live in your environment? Can you identify them?

     

  • Do cut flowers last longer if you put them in warm water or in cold water? You can test how effectively flowers are drinking water by adding food coloring to it and using white cut flowers, such as carnations. Do flowers drink warm water faster, slower, or at the same rate as cold water?

     

  • Do raw eggs and hard-boiled eggs spin the same length of time/number of times?

     

  • What type of liquid will rust a nail the quickest? You could try water, orange juice, milk, vinegar, peroxide, and other common household liquids.

     

  • Can you tell from today's clouds what tomorrow's weather will be?

     

  • Collect a few ants. What foods most attract ants? Least attract them?
