Understanding Waves: Energy, Mediums, and Types of Waves in Physical Science

DESCRIPTION

This structured reading guide helps students explore the concept of waves, their ability to transfer energy, and the mediums through which they travel. It includes observational activities with Slinkies to demonstrate wave behavior, along with definitions and explanations of transverse and longitudinal waves. Students are encouraged to create study cards using their own words and illustrations, reflecting on their hands-on experiences. Supplementary video resources enhance understanding of wave dynamics in a scientific context.

Presentation Transcript

  1. Chapter 20 Section 1Directed Readingpg 574-579http://my.hrw.comlogin: jcarlson652pass: science

  2. Read Pg 574 • 1) What is a wave? ________________________________________________________________________________________________________________________________________________________________________ • 2) Waves move energy. Use the picture at the bottom of pg 574 to explain this. ________________________________________________________________________________________________________________________________________________________________________ • Use the Gloss app to make a study card for Wave. Remember to draw a picture, and write it in your own words.

  3. Reflect: Slinkies • Based on your slinky observations, how is a slinky a wave? Draw some pictures to explain.

  4. Read pg 575-576 • Waves and Work; What evidence exists that proves waves transfer energy to do work? ________________________________________________________________________________________________________________________________________________________________________ • Energy Transfer Through a Medium; What is a medium?____________________________________________________________________________________________________________________ How is energy transferred through a medium?______________________________________________________________________________________________________________________________________________________________________________ • Use your gloss app to make a study card for Medium.

  5. 575-576 Continued…. • Energy Transfer Without a Medium: Look at the picture on pg 576. What kind of waves can travel without a medium? ____________________________________________________________________________________________________________________ Do waves that can travel without a medium, pass through a medium? Why or why not?____________________________________________________________________________________________________________________ Challenge: Do the Activity at the bottom of page 576. Record your results below.

  6. Reflection: Slinkies continued • What kinds of mediums were the waves traveling through when you observed the slinkies?________________________________________________________________________________________________________________________________________________________________________ • Was there an observable difference in wave behavior, or wave data based on the medium? Example….plastic vs. metal? Large vs. Small?________________________________________________________________________________________________________________ • Go to your Physical Science Glossary App. Click on Sound and Waves. Watch the Wave video.

  7. Read pg 577-579 • Transverse waves and Longitudinal waves are not the same. Use your Gloss App to make a study card for each. Be sure to use your own words, and draw a picture. Make sure you label the parts of the waves. Use the pictures on pg 577 and 578 to help you. • Slinky reflection: You made both transverse waves and longitudinal waves with your slinkies. How are these two types of waves similar/different? ________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________

  8. Watch this….. http://quietube5.com/v.php/http://www.youtube.com/watch?v=wbp-EtVSBEs Reflect: What is happening to the energy in this wave? Reflect: Why does the slinky keep ‘walking’? Reflect: What kind of wave do you think this is?

  9. For An Extra Challenge • Go to the Physical Science GlossaryApp.Watchthe videos for Reflection and Refraction. Write about your observations in your science notebook. • Go to the Xperica HD App. Read the instructions and perform the Oscillation experiment. Write about your observations in your science notebook. • Go to the Sound Uncovered Exploritorium. Choose 6 articles to read and explore. Summarize your learning in your science notebook. • Go to the Physical Science Glossary app. Watch the videos for Light and the Electromagnetic Spectrum. Write about your observations in your science notebook.
