Science Buddies: "Ask an Expert"

Science Fair Project:
Why does the moon go around the earth. First Grade.
How do I word my hypothesis?? Need to know today, please!!

Hi Mrs. J,

Take a look at our hypothesis page: https://www.sciencebuddies.org/science- ... esis.shtml

The general idea is that you need to guess why the moon goes around the earth, and then create an experiment to determine whether your hypothesis was correct. Since this is for first grade, you'd want to keep the terms simple. Maybe you could first tell the students that really large objects are attracted to each other, and the larger the object, the harder it "pulls" on smaller objects. This is how gravity is formed and why we don't float around on Earth. Then maybe the kids could state their hypothesis? You'd want to note that the moon is smaller than the Earth, and maybe they can make a guess from that.

This idea is a bit difficult to do an experiment for, especially in first grade. You might consider doing an experiment for something more basic. Take a look at our project ideas page for some ideas (https://www.sciencebuddies.org/science- ... deas.shtml), as well as our parents page for some shorter experiments that only require readily available materials: https://www.sciencebuddies.org/science- ... arents.php

For future reference, we try our best to get back to people within 24-48 hours, but an immediate response should not be expected, our Expert volunteers log on at different times of the week.

Good luck and let us know if you have more questions!
