Stained Glass, Make Your Own Colored Lass Light

FOCUS Book

ained Now that you have learned about St stained glass, make your own colored lass light. Cut out circles from colored plastic g wrap, tissue paper, or other materials. Use rubber bands to attach the circles to a flashlight. Point the flashlight onto a white wall. Write down or draw what you see. Try making new colors by using more than one circle to cover the flashlight.

Beyond the Book Search the Internet to find pictures of stained glass. Try to spot the parts that block light and the parts that let light shine through. What Happens to the Light? AINED Look at the cup. What will happen ST when you shine light on it? LASS The cup blocks the light. The light G will not shine through. FOCUS Question What happens when light shines on objects?

Sunglasses block the parts of sunlight that can hurt your eyes. But some light gets through, letting you see.

The light shining through is many colors, too. Sunlight has all the colors of the rainbow. When it shines through the stained glass, most colors of light get blocked. Red glass lets only red light through. The green glass lets only green light through. Most clear glass lets nearly all the light through. Most stained glass lets only part of the light through. Some things do not let any light shine through.

Long, long ago, many people could not read. Stained glass windows were used to tell stories and to teach people.

Light from the Sun has all the colors of the rainbow in it. The light gets filtered through the glass so we see only that one color.

If there is no shadow, then ______of the light passes through. If there is a dark shadow, then ______of the light passes through. 3. Choose one of the objects. What kind of shadow will it make? Write or draw your answer.

4. Which object will reflect light the best? Write or draw your answer.

Associated Performance Expectation: 1-PS4-3. Plan and conduct an investigation to determine the effect of placing objects made with different materials in the path of a beam of light.

All questions in this assessment relate to the Disciplinary Core Ideas DCI of this Performance Expectation. Look for the SEP and CCC symbols for questions that specifically address Science and Engineering Practices and Crosscutting Concepts. Summary Students use evidence to identify cause-and-effect relationships between the type of material and the kind of shadow that forms when light is shined on it.

© Learning A–Z All rights reserved. 5 www.sciencea-z.com Storyline Assessment Light and Materials Lesson 4 Part 3: Plan an Investigation 1. I could shine the flashlight on the objects and see what kinds of shadows they make. The kind of shadow would tell me how much light passed through each object.

SEP 2. If there is no shadow, then all (or most) of the light passes through. If there is a dark shadow, then none of the light passes through.

CCC 3. Answers will vary depending on which object students choose. Students may write or draw their answer. Sample responses: Wood: It will make a dark shadow. Thin white fabric: It will make a light, spotted shadow. Drinking glass: It will make no shadow or a very light shadow.

Mirror: It will make a dark shadow. If students say that it will reflect light, remind them that while that is a true statement, the question asked about the type of shadow it would make.

4. Students should indicate that the mirror will reflect light the best because it is smooth and shiny.

Teaching Tips If students have trouble performing the tasks on this assessment, ask them to review the observations they recorded in their science notebook during the investigation in Lesson 4. Also review the Stained Glass FOCUS Book and the class chart created from the discussion of that book. Discuss how the type of material affects how much light passes through and therefore also affects how the shadow will look. Then work together to match each puppet to its shadow in Part 1 and to fill out the table and answer the question in Part 2. Also, review the important features of an investigation and how observations of shadows and reflections can help answer the question of whether light passes through objects.

Extensions For students who complete their work early or are ready for an extra challenge, assign additional resources related to this topic found on the Grade 1 Waves: Light and Sound NGSS page on Science A–Z.
