what is the observations in a science fair project.Ex the observations and results)?

Answer 1

This is the result of the experiment (not the interpretation of them) Most science fairs want a chart or a graph. For example, you might list your observations at time intervals.....tell what happened when you performed the experiment basically. If you're growing something, maybe measure it's growth...

Answer 2

You have a hypothesis (what you think will happen) and results (what actually happened) and a conclusion (why what happened happened). You observations are a sort of play-by-play of what is going on in between the start and end of the experiment. Watch everything and write it down or tape it. Be wordy and descriptive, so that someone not observing the experiment can feel like they saw what you did, so they will believe your conclusions and results.
Back in my day, we always listed our observations by number. Not sure what the acceptable format is now, but I sense that science teachers/folks still like numbered steps!

Answer 3

what you see your projects has done, or how it has changed. Anything you see your project do, would be your obervation.

Ex. If your project was trees, you would observe that in the fall, the leaves change colors, in the winter they lose the leaves and in the spring, they grow back the leaves.
