Lab Report: Scientific Method Your Name: Taylah Harness 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…show more content…
List examples. Notebook Activity: Conversions between units If there are 1000 meters in a kilometer, how many meters are there in 0.05 km? 50 meters. If there are 1,000,000 micrometers (µm) in a meter, how many µm are there in one millimeter (mm)? 1000 µm If an object is 334 µm wide, how many mm wide is it? 0.334 mm. If we have one Liter of a solution, how many milliliters (ml) is that? 1000 mL Did your TAP water boil at 100 degrees C? If not, what might account for this? no, mine was close though it boiled at 100.5 C. i think this happened because The tap water most likely did not boil at exactly 100 degrees celsius because tap water is not pure H20. There are other impurities in it that would affect the boiling point. An experimental control is a test that lacks the experimental variable. Was one of the solutions prepared in this lab a control? If so, which one? Yes, the tap water being boiled at a 100.5 C that receives no added table salt is the experimental control. In our experiment, you controlled one of the factors. Which one (temperature or NaCl concentration) was it? i controlled the NaCI concentration. This factor was the independent variable; it was controlled by you, the experimenter. The other variable was a consequence of changes you made. This is the dependent variable. It was a consequence of changes in the independent variable. What factor (temperature or NaCl
