Investigate Activity: Changing States of Matter

Students observe water in solid and liquid states, and make inferences about moisture on the outside of a jar of ice. Materials list, advance preparation instructions, lab hints and tips, rubric, worksheets, and answer key are provided.

This worksheet includes several FutureFit Extension Activities that highlight 21st Century skills like critical thinking and wayfinding. These FutureFit Extension Activities are designed to reinforce the concepts included in the worksheet activity while integrating real-world skills. They can be used as in-class independent practice or group activities, or assigned for take-home or independent work.

FutureFit Extension Activities

Investigate (5-15 minutes)

As a follow-up to the workheet/in-class activity, print or project the Water Cycle for Kids resource from the United States Geological Survey for students and ask them to make a drawing illustrating how the process they just observed would work in the natural world as part of the water cycle. Reference prompts could include glaciers, ponds frozen in wintertime, icicles, or snowfall.

Adapt (5-15 minutes)

As a challenge question or experiment, perform the experiment on the worksheet as directed, but have students add either a 1/4 teaspoon of salt or a 1/4 teaspoon of isopropyl alcohol to the glass jar containing the ice cube. Have students make an inference about whether the evaporation cycle will progress more quickly, or more slowly, given the addition of a new substance (addition of either will make the cycle more rapid). If desired, have students make an inference about whether the volume of liquid that remains after the ice has completely melted will be more or less than the volume of the solid ice cube (volume of water remaining after the 1/4 teaspoon of salt is added will be greater).
