Sorting Salt and Pepper, How Many Ways?
In the Sorting Salt and Pepper video ( http://thehappyscientist.com/science-video/sorting-salt-and-pepper ) we saw that we could mix salt and pepper into a pile and then separate them easily by using the static charge on a balloon. I challenged you to think of other ways to separate them, and you sent in lots of great ideas. Lets take a look at some of them.
We start with that same pile of mixed salt and pepper. How are we going to sort them out? Well, lets start by thinking about how salt and pepper are different.
Balloons, pepper, salt, and paper
This video was SO COOL!!!! We did a science experiment with the salt and pepper and paper. Everyone's hair was CRAZY!!!!!!!!! The pepper from my plate was flying up onto my balloon. The paper halfway was on my desk and halfway o my balloon. I hope ALL of our experiments will be from this website!
salt and pepper with water
the pepper has neutral buoyancy, so it hovers in the middle of the water
