Investigate sound with the communication-themed activity pack - Message makers.



Aimed at 5–11 year olds, the pack contains investigative activities that allow you to conduct a sound survey of the school grounds, discover pitch, investigate why big ears hear more sound, send secret codes using Morse Code, experiment with detecting sound, act out animal communication and measure the speed of sound.

CREST Star Awards
If you are using these activities for students and would like these to be accredited, all activities within this pack can count towards a CREST Star Investigator award. There are 3 Star and 5 SuperStar activities in the pack.

Includes teacher's/background notes

Older Children
Each activity includes further ideas to take the investigation further.
