Teaching Tips

• The topic is rigorously covered if couched in the "All About Ice" curriculum for younger audiences, with multiple pages of a journal that the students fill out.
• This lesson is part of a unit, and best used as part of the unit, though can be used as a stand alone lesson.
• The journal associated with this lesson supports the entire unit so teachers will want to use the journal pages that correspond to this activity. The journal may need to be adapted for younger learners who are not able to write yet.
• Students may get distracted while watching their ice melt for several minutes. Teachers could provide real pictures or videos of icebergs melting or glaciers calving to keep their interest.

About the Content

• This activity guides students through the scientific process to find out what happens to ice when you put it in water (it floats and melts).
• They will notice that ice floats, has density which makes the water rise, and that most of the ice is in the water.
• Digitally available data and background material on the state of earth's water comes from the Lunar and Planetary Institute.
• Passed initial science review - expert science review pending.

About the Pedagogy

• This is a hands-on experiment that will get kids exploring and wondering.
• The learning outcome is focused on students understanding the states of matter of water and that ice is less dense than liquid water, thus it floats.
• Students watch an ice cube melt and make observations about the process.
• The guiding questions help develop thinking and inquiry.
• The lesson and journal are logically organized.

Technical Details/Ease of Use

• This activity is free, easily accessible, and ready for teachers to use.
