Amazing Expanding Ice

• 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.
