How Can Animals Use their Senses to Communicate?

How Can Animals Use their Senses to Communicate?

How Can Animals Use their Senses to Communicate? is part of Smithsonian Science for the Classroom, a brand new curriculum series by the Smithsonian Science Education Center. It is aligned to a group of grade 4 standards. It has a focus on life science with a secondary focus on physical science and engineering. In this module, students:

  • Analyze structures that support animals’ senses and investigate how light travels when they see an object
  • Investigate how information is processed in the brain and analyze data to determine how memories can affect behaviors 
  • Carry out an investigation into whether fiddler crabs wave more often when there are other crabs present and analyze the system in terms of sender, signal, and receiver
  • Design and test a method for sending information about a picture using 1s and 0s and short and long flashes of light
  • Construct an argument based on testing with models for which firefly flash patterns are the most effective for communicating to find a mate
