Definition of Conductivity:
"The ability or power to conduct or transmit heat, electricity, or sound. "
What we used:
Different Compounds
Distilled Water
Beaker
Conductivity Testers
Stir Sticks
The Process:
1. Destini and I set up our station, we put out the beaker, stir stick, and Conductivity Tester. We decided to make a solution using Sodium Bicarbonate.
2. We put four scoops of Sodium Bicarbonate into the beaker and then added the distilled water, and stirred until all of the Sodium Bicarbonate dissolved.
3. Then we used the Conductivity Tester by turning it on and dipping the two wires at the end into the solution.
4. Then we determined the level of conductivity by the brightness of the red and green lights on the Tester.
5. After we wrote down the level of conductivity for our solution we tested the conductivity for five other solutions, made by our classmates. Which included: Potassium Chloride, Corn Starch, Ice Cream Salt, Calcium Chloride, and Sodium Acetate.
Data:
Below is the chart from our expriment, as you can see we have some different numbers involved. When we did this lab, the conductivity tester would give us the exact response as to what the conductivity level was. To represent that I used numbers in our graph.
2 is low conductivity
4 is medium conductivity
6 is high conductivity
8 is very high conductivity
Conclusion:
As you can see most of the solutions had a pretty good level of conductivity. The only one that showed a level of low conductivity was the corn starch, but it still showed at least some conductivity. Which means that all of the solutions can conduct or transmit electricity!
