This resource provides students with a audiogram simulator students can use to guage levels of auditory perception of the right and left ear on an audiogram leading students to determine levels of hearing loss from hearing with in normal limits, mild, moderate, severe, to profound.
In this activity, learners work in teams to study the observation skills essential to scientific research. Learners work in groups and lead one blindfolded member of the group to a tree and other various places nearby. The blindfolded team member describes what he/she smells, feels, and hears while the other members take notes. Learners switch roles and at the end, compare their observations and analyze their observational skills.
This animation illustrates how we hear sound. Sounds from the outside world pass as vibrations through tiny bones in our ear to the cochlea. Within the coiled tube of the cochlea, different regions of the basilar membrane sense different sound frequencies at specific. This animation demonstrates how high-frequency sounds penetrate only a short distance along the basilar membrane and how vibrations from low tones are sensed at the farthest end of the basilar membrane.
Students learn about the anatomy of the ear and how the ears work as a sound sensor. Ear anatomy parts and structures are explained in detail, as well as how sound is transmitted mechanically and then electrically through them to the brain. Students use LEGO® robots with sound sensors to measure sound intensities, learning how the NXT brick (computer) converts the intensity of sound measured by the sensor input into a number that transmits to a screen. They build on their experiences from the previous activities and establish a rich understanding of the sound sensor and its relationship to the TaskBot's computer.
Slither in and meet what some people consider their worst nightmare! But you decide if they truly are the stuff of nightmares or a very misunderstood beneficial animal!

Did you hear that? Listen in as we try some experiments with our hearing! Hopefully after these fun experiments in our series Science in the Dark you will have a greater appreciation for the night.
