Science: Light and Sound

Puppet theater

Problem:

A puppet theater company came to Skyline Elementary. They think we might be able to solve by using light and sound. The company has many heavy parts that are too heavy to carry around. They are hoping we can help them figure out how to use light to solve this problem. They want to create a picture on the wall, using light.

How could they use light to create an image on the wall?

Classroom exploring

5 minute walk

• With a partner I want you to find areas in the classroom that are dark. Find areas in the classroom that are light. Talk to one another about what you find within the classroom.
• Why do you think some areas are dark and some are light?

Draw

Draw a picture of a light area and a dark area in the room

Essential Question

How do we make brighter or darker areas?

We are starting a new unit of science in which you will be engineers who study light and sound. Today you will learn what light and sound engineers do.

Questions to Ponder

Conclude

• Collect the books
• In the book, we saw many examples of problems. we saw many examples of problems and many examples of solutions.
• Engineers are people who use what they know to make things solve problems.
• We are going to do work like engineers do because we are going to learn new things about light and sound
• we need to learn more so we can help the puppet company solve their problem.

• What was the same in all of the pictures we just observed?
• Why does some areas look bright, and other areas look dark?
• What is something you wonder about?
• What questions do you have?

Model asking questions. Scientist and engineers ask question. Sometimes, new questions come from thier observations.

Partner Talk

Shadow Pictures

The problem:

How can you use light to make a picture on the wall so they will not have to carry all the heavy parts to their shows.

Turn to a partner. Take turns sharing what you observed and your new question.

Lesson 1.2

Show Pictures from page 41. Stop and ask questions to describe the observations.

Possible Solutions?

Shadow Puppet Activity

• How do you think this shadow was made?
• Why does this area look bright, and this area looks dark?

• Now that we talked about light and dark areas in the picture. Lets find areas that are light/dark in the classroom.
• Why do you think this area is dark? Why do you think this area is light?

We use the word "problem" a lot. When we have a problem with something we call it a problem. The word problem has a lot of meanings. When we are talking as student engineers about making designs for the puppet theater. The puppet company has a problem. Who remembers what the problem is?

Questions

Carpet Reading

What we know about Light chart

• Could you make it completely dark, where you couldnt see anything?
• Was there still any light?
• How did you know?

You and your Partner will need to come to the carpet. Please bring your books with you to the carpet.

Think about 3 kinds of places we found in the book. A bright place, a dark place and a completely dark space.

How do we make darker or brighter areas?

Questions:

• What problems did you find in the book?
• what solutions did you find in the book?
• What were the engineers trying to solve?
• What did they make to solve the problem?
• How did that solution help people do what they wanted or needed to do?
• How would our lives be different if we did not have that solution for that problem?

Engineering

Partner talk:

Are there places so dark that you can not see? What words would you use to describe this place.

Engineering:

the branch of science and technology concerned with the design, building, and use of engines, machines, and structures.

We are going to learn about how we make some areas darker and some areas lighter. If we are going to solve the puppet theaters problem we will need to learn more about light.

We looked at a lot of pictures with different light and dark places. Today we are going to focus on this question.

Partner Read

In order to help the puppet theater company solve its problem, we will work as light and sound engineers. Engineers are people who make things to solve problems.

With a partner I want you to explore the reference book. I want you to find examples of solutions to get a better idea about what light and sound engineers do and make.

Dark activity

Every 2 students get one book

Provide examples of problems and solutions in the book

Find pages that look interesting to you. Identify what the problem may be on that page and how it should be solved. Discuss it with your partner

Observing a dark place

Group reading

How could we make the classroom very dark?

Hold up "Engineering With Light and Sound"

Dark Vs completely dark

What makes something bright or dark?

Scientists and engineers look for evidence to help solve their questions and problems. Evidence is information that helps you figure out an answer or question. We are going to observe a video of a dark place to gather more evidence about what makes something light or dark?

1.

2.

3.

• Draw a rectangle with a black marker (completely dark)
• Draw a rectangle and color with a crayon (dark)
• Draw a rectangle with no color (bright)

We are going to read this book to help us understand what engineers do. This book is different than some of the books we have read together. Instead of reading the book beginning to end, we are going to read specific parts of the book to gather information.

If you see anything, it is because of light. You need light to see!

What makes something look bright or dark?

What have you learned from the book or video that helps you answer this question?

Scene 1

Pay attention to when the cave looks bright and the cave looks dark. What did you observe?

What Engineers do chart

read pgs 4-5

Scene:

A scene is the background of a play or puppet show. The puppet company wants us to figure out how to use light to make a particular picture on the wall for a scene in their puppet show.

Turn off all the lights in the class. Is it dark in the classroom now? How do you know its very dark or not? I want you all to try to make the classroom even darker. How could we do that? Put one had over their eyes. Is it darker now? Have sstudents cover both eyes. Have them try to cover the windows with construction paper. 5 minute activity.

The scenes are too heavy. They can not carry their scenes to different shows.

What is the puppet theaters problem?

• Engineers find out a problem

Problem and Solution

• When engineers hear about a problem, they try to make a solution
• A solution helps them solve the problem
• As student egineers you will solve the puppet theaters problem

What does the puppet theater need you to do?

Draw Time

Review the problem and solution structure of the reference book.

Can you see in the dark?

• Draw a picture of a place that is very bright.
• Draw a picture of a place that is very dark.

As I read this book I am going to look at the cover, title and illustrations. Why would I do this?

This book title is already a question. It gets us thinking about the types of things we may see in the dark. Picture walk and explain the cover illustration.

Questions:

• What is this scene showing you?
• How is the light being used?
• How do we make different parts of a surface darker or lighter?

"The Problem"= describes something that people wanted or needed to do but could not.

"The Solution"= descbes what the egineers made to solve that problem and help people do what they wanted or needed to do

Read the "Can You See in the Dark?" Stop to ask questions. Are there sources of light everywhere?

Vocab

Engineer:

An engineer is person who makes something to solve a problem.

• Say the word after me: Engineer.
• Lets say the word together: Engineer
• Now whisper the word to a partner at your table: Engineer
• An engineer is a person wh makes something to solve a problem.

Science: Light and Sound

We will become light engineers!
