10. What are properties of sound?
What is Sound?
Sound is a form of energy produced by a
vibration or a back and forth movement of an object.
Sound is a wave of vibrations that spread from its source of its matter.
What are properties of sound?
Loudness - The more vibrations the waves have, the more energy, the louder the sound.
Pitch - How high or low a sound is.
The faster the vibrations or the frequency, the higher
the sound.
Engage: Display focus question: What is sound? Brainstorm and discuss with students a list of all the different sounds they have heard.
Workbook p. 141A pre-assessment. Briefly play some music from an electronic device that has a speaker. Turn it off and place a paper plate on a speaker. Then pour some rice or salt on the plate. Play the music again. Let students see how the sound causes the rice or salt to vibrate and form a ripple wave pattern.

11. What is light? Light is something that allows us to see objects.
Light is a form of energy.
Light is produced by the vibrations of electrically charged particles.
Engage Activity: Direct students to look a wall chart of teacher’s choice and focus on it. Then turn off the lights, making the room as dark as possible. Ask how clear is the chart you were looking at? Turn the lights back on. Have students discuss why it was hard to see? Allow for responses. What else do you see in the room? What you really see is light bouncing off … the print on the chart, the walls, the tables, the chairs, etc. You can only see objects if they reflect light .
Explain: Distribute a light graphic organizer (LGO) for students to write light facts as the exploration of light and its properties continues.
Ask: What is light? Light is something that allows us to see objects. (Add to Light Graphic Organizer) Has light helped us do work? Does light create change? Is light a form of energy? Yes, Light is a type of energy. (Add to LGO) How does it work?
Explore with the Beam of Light activity: Let’s take a closer look at a beam of light. Remind students that it is important never to look directly at any source of light, because it could damage their eyes. Shine a flashlight at the ceiling.
Ask is light passing through air? Yes. Why can’t you see a beam of light in the air? Light is invisible just like the air. So we’ll follow these steps to observe a light beam : Ask for a volunteer from each group (about seven). Give one volunteer a flashlight. Put a small amount of talcum powder in the palm of each of the other volunteers’ hands. Line up these volunteers in pairs facing each other in a straight line with their palms extended holding the powder. Direct the volunteer with the flashlight to shine the flashlight just below the row of hands. Turn off the lights. The darker the room, the more easily the beam can be seen. Tell the participants to observe while the volunteers with powder clap their hands.
Ask. Can you see the light beam? Why? (The moving particles of light are reflecting off the talcum powder in the air.
Light is a type of energy (Add to LGO) produced by the vibration of electrically charged particles.
We’ll learn more about light by exploring light’s properties. Gr. 5 SF pp

12. What are Properties of Light?
Light travels in a straight path.
Light doesn’t travel through all objects.
These are defined as opaque.
Light can be absorbed and changed to heat.
Engage:
What kind of path did the light from the flashlight take in the previous activity? Then demonstrate the following with a volunteer:
From a distance of about five meters, point the flashlight in its off position at the board. Have a new volunteer draw a big X on the board where he / she predicts the flashlight beam will hit. Then turn on the flashlight. Observe the beam. What happened?
Gr. 3 Physical Science AIMS activity: Flashlight Findings pp
Explain: (Add to LGO) Light travels in a straight path. Gr. 5 SF p
Then repeat except this time have a volunteer place a thick piece of cardboard (or some other kind of opaque object ) in front of the beam. What happened this time? The light rays are blocked, and the cardboard casts a shadow. (Add to LGO) Light doesn’t travel through all objects. The cardboard absorbed the light rays. Absorbed light is converted into some other form, such as thermal energy. Can someone explain why most car owners prefer a light color car interior versus a black interior? What kind of energy is light converted to in this example? (heat)
Add to LGO. Light can be absorbed and changed to heat.

13. More Properties of Light…
Light bounces off or is reflected from some kinds of opaque objects.
What are objects that let all light pass through them known as?
transparent
What are objects that let some light pass through them are known as?
translucent
Angles of Reflection
Explain: Light will not travel through all objects, however it is not always absorbed. The moon makes no light of its own. Instead, it reflects the light that shines on it from the Sun. SF Gr. 5 p
Explore: Let’s try modeling this property through the Reflecting Light Activity. Call for four volunteers. Give each one a number. Provide three mirrors and a flashlight. Number one volunteer will hold the flashlight, while the others will hold the mirrors. Choose a spot on a wall and challenge the volunteers to reflect a flashlight beam to that spot.
As # 1 with the flashlight shines the beam on # 2’s mirror, challenge # 2 to aim the mirror at # 3’s mirror and reflect the light in that direction. Then # 3 bounces the beam to the fourth person, who tries to aim the beam at the designated spot on the wall. What path did the light take from mirror to mirror? Why?
Explain: Let’s take a closer look through an online tutorial. Click on the hyperlink Angles of Reflection.
Must be in slide show mode.

14. Bending Light Lab Write down responses on your note page.
Problem: What does light do when it travels from one medium or state of matter (air) through another medium (water)?
Hypothesis:
Test and Observe: Follow steps from the lab sheet.
Conclusion:
Apply: Draw a light path though a cup
of water and explain it.
Explore and explain (SF Gr. 5 p ) with the Bending Light Lab:
Pass out a clear plastic cup, and container of water to each group.
Have participants observe the clear plastic cup, the water and the air in the room. Ask what do these three objects have in common? They are all see through or transparent. Light is passing through them.
Pass out the Lab sheet and a straw to each group.
Problem: What does light do when it travels from one medium (air) through another medium (water)?
Hypothesis: What do you think will happen?
Test and Observer: Follow steps from the lab sheet.
Conclusion: The light passing through the air slows down when it enters the water. The water caused the light to bend or refract and make the straw look bent. When a light beam strikes a cup of water, it changes direction or bends. This is called refraction.
Grade 3 AIMS Activity: Light Rays Slow Down pp

15. When does Light Changes Direction?
Light bends or refracts as it passes from one medium (form of matter: solid, liquid or gas) to another.
Refraction of Light Virtual Tutorial
Explain: (SF Gr. 5 p )
Have participants add the refraction light property to their LGO. What different mediums did the light pass through? Air, plastic, water What property do all of these objects have in common?
They’re transparent.
Explain: If time allows use the hyperlink to take the participants on a virtual refraction tutorial that elaborates and allows for clarifications.
Extend: What ways have people found to use bent light? Magnifying glass, eye glasses, telescopes, microscopes

16. What is Thermal Energy?
Thermal energy is the total of all the kinetic and potential energy of the atoms in an object.
When any form of matter gets warmer, the kinetic energy of its atoms increases.
The object’s particles move faster, so its thermal energy increases.
A change in thermal energy can lead to a change in phase or state of matter.
Temperature is a measure of thermal energy.
Engage: SF TE p Quick Activity as a teacher demonstration. Materials: balloon, empty plastic water bottle, bowl of ice, thermos of hot water Put the balloon on top of the bottle opening Place it in the container of warm water. Observe. The balloon will inflate. Why? 3. Then place the same bottle and balloon into the container of ice water. Observe. What happened? Repeat steps 2 and then 3 again. What happened? Why?
Explain: Students read p. 462 to find out what is thermal energy is and what it has to do with the balloon inflating and deflating.
Students take notes as you read/discuss Gr. 5 SF pages 462 – 463 together. Students can also read ScienceSaurus pp. 288 – 291 for added information including sources of heat.
