Search for fourth-grade science projects

Building on what they learned in third grade, fourth graders add a new level of sophistication to their senior science projects. In addition to describing data quantitatively, children begin to use their observations to form scientific arguments and participate in scientific debates. A fourth-grade science fair project might get kids beyond testing a hypothesis - could encourage young scientists to use their results to predict what might happen when the experiment expands to test new variables. The idea for the fourth-grade science fair project selected by the online lottery was carefully written in the minds of fourth-graders, providing them with the tools they needed to effectively understand the world around them by methodically seeking answers to questions.
