## Texas Go Math Grade 5 Lesson 14.2 Answer Key Graph Data

Essential Question
How can you use a coordinate grid to display data collected in an experiment?

Investigate

Materials

• paper cup
• water
• Fahrenheit thermometer
• ice cubes
• stopwatch

When data is collected, it can be organized in a table. A. Fill the paper cup more than halfway with room-temperature water.
B. Place the Fahrenheit thermometer in the water and find its beginning temperature before adding any ice. Record this temperature in the table at 0 seconds.
C. Place three cubes of ice in the water and start the stopwatch. Find the temperature every 10 seconds for 60 seconds. Record the temperatures in the table.

Make Connections

You can use a coordinate grid to graph and analyze the data you collected in the experiment. Step 1
Write the related pairs of data as ordered pairs.
(0, ___) (30, ___) (50, ___)
(10, ___) (40, ____) (60, ___)
(20, ___) Step 2
Construct a coordinate grid and write a title for it. Label each axis.
Step 3
Plot a point for each ordered pair.
