OBJECTIVE(S)

 TLW:

Describe how light behaves when it strikes objects and materials (e.g., transparent, translucent, opaque)

TLW explain  that you can
change the direction of light by using a mirror and/or lens

TLW explain that you can change the direction of light by using a mirror and/or lens

TLW:
1)Identify sources of light.
2) understand that light travels in a straight line. 3) understand  what happens when light strikes an object.

MATERIALS/TECHNOLOGY

Provide a variety of objects and materials (e.g., white paper, colored paper, a book, sheer material, plastic wrap, waxed paper) and a flashlight.

Comb, piece of construction paper, small mirror

Video-United streaming, prisms, small mirrors, magnifying glass

Text book

CUR. GUIDE Activity# 3

PAGE 9                                Students will make predictions as to whether or not the light will pass through the object and justify their reasoning. Working in pairs or small groups, have the students hold up an object and shine the light on it.  Through class discussion, introduce the terms opaque, translucent, and transparent. The teacher should lead a class discussion by having students relate the appearance characteristics of the objects to the terms. Ask students to describe how light behaves when  it strikes objects and materials.

CUR. GUIDE Activity# 4 Page 9-10          In this activity students work in small groups to investigate how light travels. Facilitate a student discussion on safety issues related to looking directly at the sun. Have students hold a comb, with its teeth pointing upwards, just in front of a backdrop such as a box top or piece of cardboard. Aim the comb at the sun. As the white light passes between the teeth of the comb, the students will notice the light rays hitting the backdrop. Discuss how the light usually travels in straight lines. This is why light casts shadows.

Have students predict what will happen if they placed a mirror in the path of the light rays and justify their prediction. Next, have the students hold a plane mirror in the path of the rays. Observe how the mirror reflects them.  Have students record observations through drawings in their science journals. Discussion could include the following:

·        Describe what happened to the light as it passed through the teeth of the comb.

·        What did this demonstrate?

·        What happened when the light hit the mirror and why did it happen?

CUR. GUIDE Activity #5 Page 10      Review discoveries from the activity, Mirror Magic. Have students predict whether or not light has a color. Facilitate a discussion of the predictions and probe for an insight into their explanations. Provide an opportunity for students to share questions they may now have about light and that they could possibly test through investigations. Show Unitedstreaming video clip, Everyday Science – Creating a Rainbow: Exploring the Spectrum of Colors in White Light or other content-appropriate video. Have students discuss the video clip and determine if any of their earlier questions were answered.

Give students prisms to explore how light breaks apart into colors of the rainbow. Through direct instruction and sketches,

elicit from students that the light is bending (changing directions) as it passes through the prism. Discussion questions could include the following:

·        Why does the light bend as it passes through the prism?

·        How can you change the direction of light?

Have students experiment with mirrors or lenses to change the direction of the light.

Have students view objects with a magnifying glass. Have them note that the objects appear to be larger and closer to them when viewed through the lenses. Introduce the concept that this appearance is due to the light’s being bent as it passes through the lens.

Review for quiz

Use text book pages B32-B37 Lessons 5 and 6

ASSESSMENT (Teacher observation, questioning, activity, quiz, etc.)

Concepts to learn:

1.       Light passes through a window.

2.       When light is blocked a shadow is formed.

3.       Light bounces off a mirror.

4.       Light bends going through a magnify glass.

5.       The sun is a source of light.

List 3 other  sources of light.

A rubric should be used to record observations. Have students place a checkmark in the appropriate column that describes the object they are investigating. Place completed chart in science journal.

Use rubric for graded activity.
