CURRICULUM Body of Knowledge Physical Science

Big Idea 10. Forms of Energy Benchmark(s) SC.3.P.10.3 Demonstrate that light travels in a straight line until

it strikes an object or travels from one medium to another. SC.3.P.10.4 Demonstrate that light can be reflected, refracted, and absorbed.

Teacher Notes In this lesson students will:

1) Justify that light travels in a straight line 2) Give examples of the reflection, refraction, and absorption of light.

Arrange students in groups of threes or fours. Write the following discussion vocabulary words on the board. Discussion Vocabulary Reflect Bend Absorb Straight line Light Shadow Materials Flashlight Book Shine the flashlight on the book so that it cast a shadow on the board. Ask students, “What did you observe?” Possible answer: shadow, dark spot, etc. Ask students to have a discussion to explain why they observed a shadow on the board. Have students write their collaborative answer in their science notebooks. Have each group share their answers. Explain to students that shadows are created because light travels in a straight line from its source until it is blocked by an object. When something blocks the light traveling from a source, a shadow is made.

Reflect Bend Absorb Have students discuss the behavior of light in each picture (A-F). Students should choose whether the picture is displaying light being reflected, refracted (bend), or absorbed. Explain to students that pictures C and D are showing examples of light being reflected (bounced back). Light reflect well from smooth surfaces, for example smooth glass, metal, calm water, and mirrors. Explain to students that pictures B and F are showing examples of light being refracted. Light refracts, or bends, when it moves from one substance or material (air, water, glass) to another. For example picture B shows a beam of light traveling through air, when the beam hits the glass it refracts (bend), then when it leaves the glass and enters air the beam refracts (bend) once more. In picture F refraction of light makes the spoon appears broken. Explain to students that pictures A and E are showing examples of light that is being absorbed. Absorb means to take in. White light is made of different colors. The color of an object is the color that the object had absorbed. In picture A, the apple is red because it absorbs red light. White objects do not absorb any color of light. Object that are black absorbs all the color of light. ➢ This assignment can be scored and evaluated using the rubric provided in the link below: Journal Assessment Rubric: http://www.nsta.org/elementaryschool/connections/201011ReuseThatNotebookRubric.pdf

Remediate: This activity will help the students to understand that light travels from a source. Students will also understand that shadows form when light travelling from a source is blocked. Students will examine how a shadow changes when the properties (brightness, position, distance) of a light source are changed. They will also explore what will happen to the shadow when the light source is made dimmer, or when the light source is moved further away.

ENRICHMENT Have students complete this activity in pairs. In this activity, students are challenged to put a mirror on the wall, cover it, and find locations where they think they can see each other in the mirror. Through the activity, students find that light reflects at an equal angle as it arrives. Students then can explore a Java applet that demonstrates that the angle at which light is reflected is equal to the angle at which it arrives. http://www.cpalms.org/Public/PreviewResource/Preview/18912

HMH Science Fusion Unit 4 Lesson 2 How Does Light Move?

1) Introduction

2) Light in action

ENGAGE Can you name some things that light can do?

Light can reflect, refract, warm things up, and make shadows.

3) Reflecting on reflection

VOCABULARY How can you define reflect?

Reflect means to bounce off. Light reflects when it hits shiny, bright objects. Reflect comes from a Latin word meaning "to bend back."

CORE CONCEPTS What happens when light hits a shiny surface?

When light hits a shiny surface, it bounces or reflects.

EXTEND AND REFLECT On this screen, there are pictures of water, a diamond, snow, and glass. Can you think of other objects that reflect light?

Some other objects that reflect light are clear or light-colored glass jars, glass beads, shiny sequins, metal silverware, a computer screen, aluminum foil, and a mirror.

4) Recognizing refraction

VOCABULARY What is the definition of refraction?

Refract means to bend light as it moves from one material to another.

MISCONCEPTION The word "refract" comes a Latin word that means "to break up." How do you think the example of the straw in the water relates to this?

The straws look straight before they are placed in the water. Refraction is what makes the straws look bent or almost broken.

 2  

CORE CONCEPTS Can you name something that refracts?

Water is a good example of a material that refracts light. A diamond and a prism will, too.

5) When do we see shadows?

MISCONCEPTION Why does your shadow sometimes seem even longer than your body?

Shadows come in different lengths and sizes. They change depending on the angle of the light.

EXTEND AND REFLECT What would your shadow look like if the sun were right over your head?

If the sun were right over your head, the shadow would be a small spot around your feet.

6) It's getting hotter

CORE CONCEPTS What happens when an object absorbs light?

When an object absorbs light, it gets warmer. Can you think of some objects that absorb light?

Some objects that absorb light are paper, a dark T-shirt, dark clothing, and frosted glass.

7) What's going on?

EVALUATE What is it called when you see a straw in a glass of water and it looks like it is bent?

When something looks bent in a glass of water this is called refraction.

8) Sunrise

EXTEND AND REFLECT How have you experienced reflection, refraction, shadows, or absorption in your own life?

You have seen shadows on the sidewalk in the afternoon when you go for a walk. You have also seen your reflection in a window or in a piece of metal

 3  

silverware.

SYNTHESIS Why do you think that light reflects, refracts, and absorbs?

Light reflects, refracts, and absorbs because light moves. It moves in a straight line until it hits an object and has to stop. Depending on the object that the light hits, it will bounce off (reflect), bend (refract), or be taken in (be absorbed).

9) Sum it up

  1  

HMH Science Fusion Unit 4 Lesson 3 How Do Surfaces Reflect Light?

1) Welcome

2) Get started

ENGAGE How would the light travel if you changed the angle of the spotlight?

Light travels in a straight line. It the angle of the spotlight changes, light will travel at that angle but still in a straight line.

3) Things to know

CORE CONCEPTS Do all objects absorb light?

All objects absorb some light. Some absorb more than others. Black objects absorb most light.

4) Light path

EXTEND AND REFLECT We can see an object because light is reflected from the object to our eyes. Could you see an object if there was no light reflected from it?

If an object does not reflect light then no light from the object reaches our eyes. We would not see the object.

5) What to do?

CORE CONCEPTS How would the mirror reflect light if light strikes the mirror at a right angle?

Light will bounce off in the opposite direction, back the way it came.

6) What do you think?

CORE CONCEPTS When light strikes a mirror, it reflects in a different direction. What direction do you think light reflects from the mirror?

The direction depends on the angle of the light. It bounces off at the same angle

  2  

as it hits the mirror. You can measure the angle that light strikes a mirror from a line that is vertical to the mirror. You can measure the angle that light reflects from the same vertical line. If for example, the angle that light strikes the mirror is 20 degrees, the angle of the light that reflects from the mirror is also 20 degrees.

7) Make your plan

PLANNING Can you arrange the steps in a different order and still carry out the experiment successfully?

You can first turn the mirror and then turn the light on. It is easier to turn the light on first so that you can see how light is directed as you turn the mirror.

8) LetÕs do it!

EXTEND AND REFLECT The moon does not produce its own light. How can we see moonlight at night?

We can see moon because light from the sun strikes the moon and is reflected from the moon to our eyes.

9) Think about it

MISCONCEPTIONS If you move the spotlight closer to the mirror, would the angle of the reflected light change?

The distance of the spotlight to the mirror does not change the direction of the reflected light. The angle at which light is reflected from the mirror depends on the angle that light strikes the mirror.

10) What did you learn?

CORE CONCEPTS When is light refracted?

Light is refracted when it passes from one substance into another substance. For example, light is refracted when it goes from air to water.

11) Take it further

EXTEND AND REFLECT

  3  

How do you know that an object absorbs sunlight? The temperature of an object that absorbs sunlight increases.

12) What happens?

EXTEND AND REFLECT Which fabric would absorb the most light: white, yellow, or brown?

The brown fabric will absorb the most light because it is darker than the other two.

13) Sum it up
