Solids, Liquids, and Gases

Step 1. Questions

Your world is made up of solids, liquids, and gases. Many substances exist in only one of these forms. A shoe, a piece of paper, and a spoon are just three examples of solids, and you won’t find any of them as liquids or gases.

What substance can you find in any of the three forms of matter? The answer is water! Ice and snow are water in the solid form. Water vapor is an invisible gas in the air.

For this e-Journal project, you will research water in each of its forms: solid, liquid, and gas. Here are questions to guide your research:
  • What does water look like when it is in each form?
  • What determines whether water is a solid, liquid, or gas?
  • How does water change from one form to another? What are the names of the different changes?
  • Where on Earth can you find water in each of its forms?
  • What questions do you have about water as a solid, liquid, or gas?
Are you ready? Research answers to the questions listed above at the Web sites in Step 2. Take notes in the note-taking boxes. You may also research water using search engines, or look up water in books at the library.

When you are ready, follow Steps 3 and 4 to write your report.



Step 2. Research

Research answers for the questions you were asked in Step 1. Visit these Web sites. Take notes about them on this page, too!

Snowflakes and Snow Crystals
Have you ever looked at a snowflake up close? Or maybe you’ve never seen snow! Either way, check out the beautiful snowflakes and snow crystals at this Web site.

The Water Cycle
Why doesn’t the sky run out of water to make rain? The answer is because water moves from air to ground to ocean and back to air, over and over again. This process is called the water cycle. Learn all about it on this Web page.

Antarctica Online
If you want to see ice, come to Antarctica! Antarctica is the frozen continent at the South Pole. Learn all about this cold but wonderful place at this Web site.
