In this online lab, you will investigate how different bird sounds travel and what helps them travel further. Learn how to “read” sounds using a spectrogram to visualize bird sounds, predict which bird sound will travel the farthest, and learn why this is important for their behavior. Using your phone, tablet or computer, test real bird sounds under different conditions to see which work best for communicating in different habitats. Come learn about North American birds and the unique sounds they make!

Light Detecting and Ranging (LiDAR)
Light Detecting and Ranging (LiDAR) technology is using light to detect the object distances. Lasers used in LiDAR emit light pulses in infrared wavelength. These light pulses hit the object and reflect back to detector. The detector measures the time between the emitted and the detected light as time of flight (ToF) and calculates the distance of the object. LiDAR has been used in many applications such as autonomous vehicles, aerial inspection, survey and mapping, archeology, forestry, and robotics. In this activity, we will use two different LiDAR to measure the range of white, black, and silver objects.
