Standard 4.0 Chemistry

Topic C. States of Matter

Indicator 1. Provide evidence from investigations to identify the processes that can be used to change materials from one state of matter to another.

Objective c. Analyze data from observations to support the idea that when materials change from one state to another the amount of material stays the same.

Activity

DOES MASS CHANGE DURING A CHANGE OF STATE?
Part I
Pour some water into a paper drinking cup. Find the mass of the water and the cup using a triple beam balance or equal pan balance and record. Place in freezer overnight. The next day, find the mass of ice and cup and compare.

Part II
Place a frozen popsicle in a cup or container. Find the mass of the popsicle in the container and record. Allow the popsicle to melt. Find the mass of the melted popsicle and container and record.

Part III
Using the data collected in Parts I and II of the activity, discuss how changing materials from one state to another affects its amount of material. Be sure to include the following:

  • how the materials were changed
  • data from before and after the change
  • what the data tells you about how the amount of material in a substance is affected when it changes from one state to another.
