Lesson 1: Phenomenon Introduction Preview CT-STEM

Thinking About Data

Imagine you have a two identical bottles of water, both are 1 liter bottles. You plan to use the SodaStream to carbonate one of the bottles, and the method your instructor showed your class to carbonate the other. What type of data might you acquire before and after carbonation in order to compare methods?

Questions

Please answer the questions below.

Question 5.1

Describe the data you will acquire BEFORE carbonating both bottles of water. Be thorough with your descriptions and also include the type of equipment you will need to conduct your measurements.

Question 5.2

Now describe the data to acquire AFTER carbonating both bottles of water. Again, be thorough with your descriptions and include the type of equipment you will need to conduct your measurements (even if it is the same as in your before carbonation answer).

Question 5.3

A student collected data before carbonating water, the data is shown below. Predict what after data might look like for the SodaStream method of carbonation.

	Before
Volume (mL)	1000 mL
Mass of water + bottle (g)	1019.4 g
Mass of bottle (g)	21.4 g
Mass of water (calculated)	998 g
Density (g/mL)	0.998 g/mL

Question 5.4

Now use that same before carbonation data to predict what after data might look like for the method of carbonation your instructor demonstrated.

	Before
Volume (mL)	1000 mL
Mass of water + bottle (g)	1019.4 g
Mass of bottle (g)	21.4 g
Mass of water (calculated)	998 g
Density (g/mL)	0.998 g/mL
