What would be a good science project for 9th grade? I was thinking of making a lava lamp, but it seems too easy. Or seeing what type of exercise makes the human heart beat faster.

Science is the act of making observations, formulating a theory based on those observations, using that theory to make predictions, then making further experiments or observations to test those predictions. A science project is one that engages in those activities.

Building something that someone has built before would not seem to qualify by this definition. Making observations of human physiology might qualify, especially if you come at it from a different angle than usual.
