Bill Nye: Phases of Matter

Learn about solids, liquids, and gases with Bill Nye!

Please type your first and last name. Name _ Billy Nye: Phases of Matter Watch Bill Nye the science guy video to learn about the phases of matter. As you watch the video, listen for the sentences below. When you hear the sentence with the missing word, fill in the blank. You can use the pause button, or red slide to watch the video as many times as needed to fill in the blanks. Click on the blank line when you hear the sentence and the missing word. A list of words will appear. Choose the word that completes the sentence. You will use one of the words several times in different sentences. 1. The universe is made of matter.2. Matter comes in 3 phases or ways: a solid, liquid , or a gas.3. Getting things ( matter) to change phase, we need to add energy.4. Changing a solid to a liquid to a gas requires thermal energy.5. The only difference between molten (liquid) steel and solid steel is the amount of energy in it.6. Solid, liquid and gas are all phases of matter.7. For matter to “ change phases” we must add or take away energy.8. . 78% of our air is nitrogen .9. When you put something in liquid nitrogen the molecules slow down and get closer and closer together.10. The temperature of liquid nitrogen is -196 degrees Celsius.11 . What are the three phases of water? solid, liquid and gas.12. If all molecules of matter stopped moving it would be called absolute zero.13. A liquid and gas take on the shape of the container.14. To change a solid to liquid to gas you need to increase the amount of heat energy.15. To change a gas to a liquid you need to decrease the amount of heat energy.16. When matter is in the solid phase, molecules are moving very slow. It holds its shape.17. In the gas phase molecules are moving very fast. How would you change liquid water into ice? Be sure to include the word "energy" to explain how this happens. How does heating ice change it from a solid (ice) to a liquid (water) to a gas (water vapor)?
