How Do You Separate A Mixture of Salt and Pepper? Written by Sarah and Nicky
|
| In this lesson Mr. Buckman made a mixture of
salt and pepper. Then he gave us this problem: How do we separate the salt from the
pepper?
|
|
We decided to dissolve the salt into some warm water. Then we put a filter in the funnel. Then we poured in the salt and pepper solution. |
|
The filter is capturing the pepper and some of the pepper’s color is going in the beaker with the salt solution. |
|
When the water all dripped out, the pepper was separated apart from the salt solution. |
|
We put the salt solution in a petri dish to let it evaporate. Then we watched it over a couple of days. |
|
The water started to evaporate, leaving little crystals behind. The crystals happened first on the sides of the petri dish, then in the middle. |
|
Wow! The salt is forming back together in the solution. |
|
After a couple of days the solution has hardened and packed together. At the end, the salt got separated from the pepper. |
