Lab: PhET Sugar and Salt Solutions |
|
Kirjeldus
|
This activity guides a student, group of students, or a class through an exploration of the Sugar and Salt Solution sim. The idea is to introduce the concept of electrolytes and non-electrolytes and what differentiates them at the molecular scale. Prior to doing the activity it may be helpful to demonstrate to students a physical conductivity tester, showing how the light bulb lights only when there is a power source and there is an electrolyte dissolved in the water.
If I have made any changes to the activity they will be shown on the live version of this document at
