Synopsis

This experiment demonstrates that as water changes from a liquid to a solid, its density decreases by comparing the level of water in a cup before and after freezing.
In addition to the experiment, students will engage in a class discussion that gauges prior knowledge, analyze the experiment's results, and record their findings in a journal.

Positives

This experiment is relatively easy to administer.
This experiment does not involve any dangerous chemicals.

Additional Prerequisites

Students should already know the states of matter, as well as the terms density and volume.
Teachers should click the "Jump to this Activity" button in the upper right-hand corner to access the experiment's instructions.

Differentiation

The Ice Investigator Journal is better suited for older students to use independently. Younger students can use it with the help of an adult, sentence stems, or dictation.
This experiment pairs well with a lesson on sea ice cover, what's happening to it globally, and why it matters.
Teachers can use this experiment as a conceptual introduction to the molecular structures of different states of matter.
This experiment can supplement a classroom discussion about the state change that occurs when water boils.
This experiment can enhance a classroom discussion on common state changes that happen in nature.
