AIM
•CAN SALTWATER BE UTILIZED TO POWER A LIGHT BULB?
PHET SIMULATION
• GO TO LABS (link on the left side)• Click on the Labs folder• Scroll to the bottom and choose
Lab 09 – Ionic/Covalent• Today we are working on the
Macro Tab lab portion
PHET SIMULATION
• Click on the PHET Simulation to launch it• Follow the instruction to launch the simulation
PURE WATER
• In this lab we are looking at conductivity.• First we will see if water alone is able to
conduct electricity. Do steps 1 and 2 and record your observations.
SALT
• Now let’s see what happen when you add salt to water.
• Do step 4 and record your observation and answer the question. This should take about 5 minutes.
SUGAR
• RESET THE SIMULATION• NOW, GO TO STEP 5-6 AND PERFORM THE
STEPS BY ADDING SUGAR TO THE MIX.• WHAT HAPPENS?
POST LAB
• What is the bond that exists in salt (NaCl)?• What is the bond that exists in sugar
(C12H22O11?• Does ionic compound conduct electricity?• Does covalent compound conduct electricity?
AIM PROMPT
• RESPOND TO THE FOLLOWING:– AIM Prompt: Can saltwater be utilized to conduct
electricity? • Respond in paragraph form and make sure to
