Students use ultrasonic sensors and LEGO MINDSTORMS NXT robots to emulate how bats use echolocation to detect obstacles. They measure the robot's reaction times as it senses objects at two distances and with different sensor threshold...

In this activity, students will experience echolocation themselves. They actually try echolocation by wearing blindfolds while another student makes snapping noises in front of, behind, or to the side of them.

Echolocation is the ability to orient by transmitting sound and receiving echoes from objects in the environment. As a result of a Marco-Polo type activity and subsequent instructional activity, students learn basic concepts of...

In the previous lesson, students learned about the issue of bycatching by fisheries and how it affects marine habitats. Dolphins are one of the main species affected by bycatching. Dolphins use echolocation to identify the location of...

This clear and concise resource on sperm whales includes a diagram and information on its diet and echolocation.

Bat Conservation International has 24 biologists, educators, and administrators who are dedicated to their mission to further education, research, and conservation of bats. Dr. Merlin Tuttle and his staff have constructed Bats4Kids to...

Explore this site to understand facts and general information about bats. Learn about bat wings and houses, why they hang upside down, echolation, and more! Classroom activities and games are also included.

At this site, provided by the Contra Costa County Office of Education, you can get the facts on bats and their environment.

Students' understanding of how robotic ultrasonic sensors work is reinforced in a design challenge involving LEGO MINDSTORMS NXT robots and ultrasonic sensors.
