Use Echolocation with a friend to find out how dolphins find food in the ocean.
This activity is pulled from our Virtual ExCEL Camps happening summer of 2020! While these activities are written to fit into the larger lesson plan of the camp themes, you can complete them with your little one at any time. Learn more about our Virtual ExCEL Summer Camp here!
Appropriate Age Range: 5 years of age and up
- cardboard tube (2 Paper towel rolls or wrapping paper roll)
- tin pan or pie dish
Some of these terms may seem brand new so take some time to look them up and they will be part of your vocabulary too: Echolocation, whisper, echoes
Tape your tin pan or pie dish on it’s side to a table or other flat surface. One person whispers into a paper towel roll that is pointed toward the tin while a friend points the other paper towel roll toward the tin and places his/her ear on the roll. Then with a friend, take turns whispering and listening for echoes. You can whisper secret messages, jokes, or even spell words for the other person to figure out.
Try standing at different distances and listen to see if the whispers get louder or quieter. Dolphins make sounds under the water, the sounds will bounce off a school of fish creating an echo, and dolphins use these echoes to find out exactly where they are.
Dolphins are not the only ocean animal with cool tricks for survival. Below are some science experiments based on cool survival skills of other ocean animals.
