This is an experiment I have used with my first graders. It is in a reproducible format that the students can use as they do the experiment and write in their responses such as their Hypothesis, Data/Observations, Conclusion and Further Questions to Explore. There are 9 Word Cards you can use on a Word Wall that have to do with Gravity. There is a Student book with 6 pages (each page is half a sheet) that has information about gravity and areas for the students to fill things in.
This is for a beginning look at gravity.
