SUGGESTED TIME 50 minutes OVERVIEW Students will conduct testing to determine if face masks or face shields  provide better protection of the user and of others around them, from droplet transmission of respiratory viruses expelled from the nose and mouth. Students will test existing designs of face masks and face shields. Students will then analyse the results of testing and re-design or design their own face mask or face shield to make a more efficient product. Students will test their own designs and present a comparison of their findings. Students will listen to each other’s presentations then conclude if they feel safer using a face mask or face shield.  VOCABULARY Face MaskFace shieldRespiratory virusesDroplet transmissionNoseMouthEngineering Design ProcessDesignRe-design
