Science Lesson on States of Matter and Energy Changes

This science lesson covers the different states of matter (solids, liquids, gases, and plasma) and how energy changes can cause matter to transition between states. Students will learn about the properties of each state and how to identify independent and dependent variables in scientific experiments.

  4. Matter: It’s what the world is made of.

  5. What is matter? • Matter is anything that has mass and takes up space.

  6. Gases Plasma What do you know about matter? Solids Liquids

  7. Solids • Solids have definite shape and definite volume. • Solids have mass. • Solids take up space. • Objects don’t pass through easily. Read more!

  8. Particles in Solids: • Are packed tightly together • Have very little energy • Vibrate in place

  9. Liquids • Liquids take the shape of their container and have definite volume. • Liquids have mass. • Liquids take up space. • Liquids have surface tension. Read more!

  10. Particles in Liquids: • Are loosely packed • Have medium energy levels • Particles flow around each other

  11. Gases • Gases spread out to fill the entire space given and do not have definite volume. • Gases have mass. • Gases take up space. Read more!

  12. Particles in Gases: • Move freely • Have LOTS of energy

  13. Plasma • Lightning is a plasma. • Used in fluorescent light bulbs and Neon lights. • Plasma is a lot like a gas, but the particles are electrically charged. • Plasma can flow like a liquid.

  14. Particles in Plasma: • Are electrically charged • Have EXTREMELY high energy levels

  15. STATES of matter? What would it take for matter to move from one state to another?

  16. Energy determines the state!

  17. When energy is added, particles move faster! When energy is taken away, particles move slower! Add or Subtract Energy. . .

  18. What will happen? Why?

  19. Solid + Energy = ? • When energy is added to solids, they become liquids! • Examples?

  20. Liquid + Energy = ? • When energy is added to liquids, they become gases! • What examples can you think of?

  21. Changing States • There are several names for matter changing states: • State change • Phase change • Physical change

  22. So, did we get something new? • Ice cream and melted ice cream? • Chocolate and melted chocolate? • Ice, water, and water vapor? • Steel and molten steel?

  23. Review Questions • What state of matter has definite volume and definite shape? • Describe the properties of liquids. • Describe the differences between gases and plasma. • What is needed for states of matter to change phase?
