I re arranged the pieces to make a animal shapes.
First I made a square piece of paper because tangrams are made from a big square.
I am a Year 6 student at Panmure Bridge School, Auckland, New Zealand. My teachers are Mr Wong and Mr Ogilvie.
Properties of Sound
PROPERTY: a characteristic that something is known by. For example, a property of ripe strawberries is that their colour is red.
OBSERVE: to watch and remember what happened.
EXPERIMENT: to observe what happens to something when different conditions are imposed on it.
CONDITION: a state of being.
IMPOSE: to make someone or something do something.
HYPOTHESIS: a prediction or evidence based guess that can be tested to find the truth.
What properties of sound can you figure out? There will be a bunch you can figure out by just experimenting with sound. Watch the video to find out how to do the experiment.
Fill out this table with your observations and hypotheses about the properties of sound.
You will need to use a sound meter like this free online meter by Youlean.
Observation I think... | Evidence | Hypothesis ✅ ❎ |
Sound is louder when it’s closer to the source and quiet when the sound it’s far away from the source | When Mr Wong bounced the ball far away from the Source the meter was low. and when he bounced the ball near the meter | When sound travels it gets softer or weaker |
The meter recorded the same sound on the top,bottom,and the sides but it was basically the same number. | Sound can travel around corners |
