Part A: "Micro" Tab Make sure you are reviewing Unit 4 Lessons 4-6 to help with portfolio concepts.
"Micro" Tab Part A - Watch the video with the pHET demonstration or go to the pHET Virtual Lab and complete the steps on your own. Answer the following questions
Add sodium chloride (NaCl) to the water. Sodium chloride is salt and sucrose is sugar. Switch the solute to sucrose (C12H22O11) and add this to the same solution. Answer the questions below.

Micro" Tab Part B - Watch the video with the pHET demonstration, read the information below and review U4L5 pg. 2 :
"What is Conductivity?"
"Solutions are all around us. While ionic solutions of different strengths are used as conductors, covalent solutions, which contain covalent molecules, and covalent compounds are used as insulators.
Electricity is energy that comes from the movement of charged particles. In this diagram, the electrons in the metal wire move from the positive end of the battery to the negative end. Similarly, in a solution containing ionic compounds, the charged ions move when they're part of a circuit."

Question 1
- sodium chloride dissociates into ions and the sucrose does not
Question 2 (select all that apply)
- a sugar molecule is made up of nonmetals and salt is made up of a metal and nonmetal
- sugar is a covalent compound, salt is an ionic compound
Brief explanation: Sucrose is a covalent molecule composed of nonmetals (C, H, O) and does not ionize in water, while NaCl is an ionic compound (Na metal + Cl nonmetal) that dissociates into ions and conducts electricity in solution.
