Why are lunar eclipses more commonly seen than solar eclipses? why are lunar eclipses more commonly seen than solar eclipses? the tilt of the moon's axis is smaller than the earth's. the moon goes around the earth faster than the earth goes around the sun. the earth casts a bigger shadow than the moon. the moon is much closer to the earth than the sun. lunar eclipses occur at night and are easier to see?

This is all you, but i can give you some topics that you could try. if it rained when you want to do something outdoors, it 'limits' that human activity. maybe you want to do an experiment that goes throughout the whole year and you have to have above freezing the entire year. this 'limits' your activity. i thought of those just off of the top of my head. something that gets to me that might be getting to you is you are thinking too hard about what to do. think simply, and if it is too simple, then bump it up just a little bit.
