Lesson Planning

Teaching

Investigate the nature of vibrations through touch and sight as well as hearing.
Set up fair tests to investigate the transmission of sound through different materials (including water - Yr4).

Activities

Investigate vibrations through sight and touch as well as hearing (Yrs3&4).
Discover first hand that when objects vibrate, sound is created and that vibrations spread out from the source of a sound (Yrs3&4).
Investigate which materials transmit sound and which do not (Yrs3&4) including water (Yr4).

Investigation - exploring, fair testing
You have discovered that sound is made of vibrations but now the band want to know more about how sound travels and what it can travel through (air? Water? Solid objects?) Set up some investigations to compare different sounds travelling through air, water, windows, doors and walls. How can you make a louder/quieter sound? How can you keep the volume the same? Measure in decibels using a data logger.
Year 3 - Find median of 3 measurements record in given table and bar graph.
Year 4 - Find the median of 3 measurements. Create own table and bar graph.
