Purpose of this Lab
What is the goal of this lab? What question is it trying to answer, or what problem is it trying to explain?
The goal for this lab is to be able to get the boiling water's temperature to increase by adding table salt. The problem it is trying to explain is, how does table salt affect the boiling temperature of water? does it increase or decrease? or does it stay the same?
Hypothesis
After reading the lab instructions - but before starting the lab - record your best “educated guess” about what will happen in the experiment. What hypothesis can you generate about the effect of adding salt to water?
Adding table salt to boiling water will cause the water to boil at a higher temperature.
Experimental Design
List the materials used in this lab, and the procedure you followed.
Materials:
1. Kitchen stove or electric hot plate
2. One 2-cup measuring cup
3. Measuring spoon set, with one tablespoon maximum
4. Table salt
5. Tap water
6. 2 quart cooking Pot (1/2) i don't have sorry
7. One digital thermometer
Procedure (list steps in the order in which you performed them):
1. Boil one quart of tap water on stove.
2. Measure the temperature of the boiling water. Record highest temperature reading.
3. Add the measured salt to the boiling water and stir.
4. Measure the temperature of the boiling water with the salt in it. Record the highest temperature reading.
5. Repeat this process the second time with 2 spoons of salt and the third time with 3 spoons of salt.
Data
Record the data you collected in the lab. (The data table and the graph.)
