Can I test density for magnetic slime? Need guidance with slime variation for son's science fair experiment

My 7th grade son and I are looking to do the variation on the slime experiment using magnetic slime but instead of observing qualitative results (is it stick? slimy? etc?), we are wanting to test the density. Does that make sense or is it a smart thing to test?
Also, how could we relate an experiment like this to real life? Thanks in advance!

Hi,
Providing a couple links for resources about magnetic slime on our site in case you haven't seen these already:
https://www.sciencebuddies.org/stem-act ... ime-recipe
The first one is a "just for fun" activity that doesn't have independent and dependent variables that you would need for a science project. Density is a variable that you could change in your slime (for example by changing the amount of iron filings) but you would need to decide what else you would measure as a result. Our guide on the scientific method might help you here:

As for real world applications, check out the video in this project about a magnetic slime "robot" that for example, doctors could guide around inside a person using magnetic fields:

Hope that helps!
