Materials:

• Balloons of various shapes and sizes
• String (or fishing line works best), enough to cross an entire room
• Tape
• Straw
• Scissors
• Paper (or print the sample data sheet on page 2)
• Pencil
• Tape measure
• Ruler

What to do:

• Tie one end of the fishing line to a chair, door knob, etc.
• Pass a small piece of straw (about two inches) through the fishing line.
• Secure the other end of the fishing line to another object.
• Choose a balloon to test and make some predictions on your paper
  • What balloon shape do you think will travel the farthest? Why?
  • What balloon size do you think will travel the farthest? Why?
    • If you do not have different balloon shapes, think about the size you blow your balloon to.  How will this affect the distance traveled?

• Blow up your balloon, pinch it shut and tape it to the straw at one end of the fishing line.
• If you are looking at the size of the balloon, measure the diameter of the blown up balloon before letting go.
• Let the balloon go and measure how far it traveled.  Record your data.
• Try again with different shaped balloons or change the amount of air you blow into your balloon.  Collect your data after each try.

Why did this happen?

• Look at all of your data.  
• What happened to your balloon?
• Was there a difference between smaller and larger balloons?  Why?
• Where does the balloon get the energy to move across the fishing line?

Engineering Design Read Aloud Books:

Materials:

1. Paper to make a plan
2. Pencil
3. Cardboard box(es)
4. Other materials such as crayons, construction paper, masking tape, etc.

What to do:

• Your challenge is to design a new object or tool that you can use in your home to solve a problem using a cardboard box.
  • This can be something that you already have but want to improve.
  • Or it could be something that is new.

Experiment 1:

Materials:

1. Two plastic cups (can be recycled materials, such as a small yogurt or sour cream container)
2. String – about 10 ft (or fit to the size of your home)
3. Metal hanger (optional)
4. Spoon (optional)

Preparation (for adults):

1. Punch a small hole in the bottom of each cup
2. Pull the string through each cup to make cup and string telephones

What to do:

1. Have one person at each end of the cup and string telephones
2. Hold the string tight and one person listens while the other whispers into the cup.  What do you hear?
3. Hold the string loose and one person listens while the other whispers into the cup.  What do you hear?
4. Next have each person listen at each end of the cup and hold the string tight.  Have another person pluck the string.  What do you hear?
5. Hang a metal hanger on the string while two people listen.  Lightly tap the hanger with the spoon.  What do you hear?
6. How does the sound travel to your ear?  
7. Draw a picture to show how the sound moves to your ear.

Experiment 2:

Materials:

• 6 pieces of string – about 3 ft each
• Hangers – 1 metal, 1 plastic, 1 wooden (with a metal top is okay) 
• Spoons – 1 metal, 1 plastic, 1 wooden

Preparation (for adults):

• Tie each string to each bottom end of the hangers, like this

What to do:

1. Using one hanger at a time, wrap one end of the string around your pointer finger on each hand
2. Place your fingers in your ears
3. Have someone else use each type of spoon and lightly tap the hanger as it hangs in front of you.  Try not to let the hanger touch your shirt.  What do you hear?  Is the sound different or the same with each spoon?
4. Try each hanger with the different spoons.  What sounds the same?  What sounds different?
5. How does the sound travel to your ears?
6. Draw a picture to show how sound travels.

Materials:

1. Flashlight
2. A dark surface
3. Paper to write down patterns
4. Pencil
5. Yellow crayon
6. Black crayon

What to do:

Create your patterns

1. Take your flashlight and try shining it on the dark surface.  Can you see the different patterns you can make?  

• Example:  The word 鈥渉ello鈥� can look like this with light patterns:

• Or something different like this: 鈥淗ow are you?鈥�

• Use your flashlight to draw shapes that represent words.

2. Try to make a pattern, shape or signal for each letter of the alphabet, numbers 1-10 or common words.

3. Write down the patterns that you create on your paper.

• Write the letter, number or word with the pattern next to it.
• Write down the patterns that you create on your paper.

Test it out

1. Have a conversation with someone at home without saying a word and see if they can crack your code!  
2. Let them use the patterns you wrote on your paper as a key.
3. Have them create new patterns and see if you can guess what they are saying too!

Materials:

1. Newspaper
2. Tape (masking tape works well)
3. A book, to be a weight

What to do:

Strong Towers

1. Take a sheet of newspaper and experiment with making different shapes with it. 
2. Place the book on top.  Does it hold the book up?  If not, how could you change your shape to make it stronger? Tip for adults: A rolled cylinder can be quite strong, especially if several cylinders are taped together side by side
3. Take more sheets and make more shapes.  How strong can you make your newspaper structure?

Tall Towers

1. Now try making a tall structure.  
2. How can you fold or roll your newspaper to make a long or tall shape?
3. Try taping several pieces together.  How high can you go?  Can you make a tower that is taller than you?
4. If your tower starts to fall over, how can you solve that problem?  How can you make it stronger?  
5. Think about towers you鈥檝e seen out in the real world.  How are they built?
