Creating and Understanding Duck Callers

Jess introduces a fun science project to make a duck caller using a cup, string, and paperclip. The video provides a step-by-step guide on assembling the materials and explains the science behind the sound produced, emphasizing the role of vibrations and amplification. Viewers are encouraged to experiment with different variables to see how they affect the sound.

What is the main purpose of the video tutorial?

• To teach how to make a duck caller

• To explain the history of duck calls

• To show how to make a paper airplane

• To demonstrate different types of bird calls

Which of the following is NOT a material needed for the duck caller?

• A paper cup

• A piece of string

• A rubber band

• A paperclip

What is the first step in creating the duck caller?

• Tie the string to the paperclip

• Make a hole in the cup

• Dampen the cloth

• Thread the string through the hole

How do you secure the string inside the cup?

• By gluing it to the cup

• By tying it to a rubber band

• By taping it to the cup

• By tying it to a paperclip

What action produces the duck-like sound?

• Tapping the cup

• Pulling on the string

• Shaking the cup

• Blowing into the cup

What role does the cup play in the duck caller?

• It acts as a weight

• It holds the water

• It changes the color of the string

• It amplifies the sound

What scientific principle is demonstrated by the duck caller?

• Magnetism

• Vibrations and sound amplification

• Chemical reactions

• Thermal expansion

What can you experiment with to change the sound of the duck caller?

• The color of the cup

• The length of the string

• The type of paperclip

• The size of the cup

What happens if the string is not wet enough?

• The sound will be softer

• The cup will not vibrate

• The string will break

• The sound will be louder

What is the effect of changing the length of the string?

• It changes the pitch of the sound

• It changes the color of the cup

• It makes the cup heavier

• It has no effect
