Today you are going to investigate volume. How is volume affected by distance?
Set your phone/tablet/TV to make a sound, move 10 steps. Away, how well can you hear the sound? Give it a score out of 5. Move another 10 steps away, repeat. Do this about 5 times. What do you notice? Fill in your investigation sheet from your pack. Think about:
what thing did did you change each time?
What this did you measure/observe/listen for?
what did you keep the same?
Method - what did you do?
Results - the number of steps and each score
conclusion — what did you find out about the investigation title? How do you know?
