DESCRIPTION

Speed of Sound

Physics, Math, Engineering

Which is faster: Speed of Sound or Speed of Light?

Decibel

Physics, Math, Engineering

What is a decibel? what level is considered dangerous to your hearing? What decibel range is normal conversation?

Concert Hall

Physics, Math, Engineering

Relate Logarithmic scale to concert hall design

Logarithm Lab

Physics, Math, Engineering 

To teach students the importance of logarithmic scale and compare it to linear

scale

Log what is it?

Physics, Math, Engineering

Logarithm is related to dB which is related to sound. Objective is to have students understand how to use logarithms.

Machines

Physics, Math, Engineering

Topic to relate acoustic machines to the simple machines the students are learning

about

Megaphones

Physics, Math, Engineering 

Objective is to have students see how the

shape of the cone affects the energy of the sound.

Waves

Physics, Math, Engineering

How does a transverse wave and a longitudinal wave look? Show students how each wave travels. 

Oscillating Drum

Physics, Math, Engineering 

Objective is to calculate the speed of the wave.

 

Centroids

Physics, Math, Engineering 

Given an irregular shape, find its centroid.

 

Airplanes

Physics, Math, Engineering 

Find the centroid of paper air plane and then fly it. Check for stability.

 

Sound

Physics, Math, Engineering 

Hear and see how sound travels. What is the relationship between sound loudness and the distance of the sound pressure level meter?

 

Speaker Cone

Physics, Math, Engineering 

Is there a relationship between the volume of the cone or the volume of the cylinder in relation to the sound pressure level measured?
