Sound And Energy
In class this term we have been learning about Energy. Energy can not be created or destroyed it can only change its form. moving on to sound energy. Sound travels faster through objects than air. So how dose sound bounce of things if it travels through it.
Here is a example of it changing form. If you tern a light on the electric energy travels through the wires to the light and then it produces light energy. We did a test to see if sound travels faster than light. so the class ran down to the goal posts at the back of the field and Mr Marquand clapped with some blocks and we saw him clap and then about two or three seconds later we heard the clap.
We watched a couple of videos of sonic booms and how it makes a cloud thing. after it fly's past we hear the jet engine so two tests show that sound travels slower than light.We also put a speaker into black rubbish bag and but liquids on the bag and them put some music through the speakers. this experiment helps us understand that sound travels through vibrations. We learnt that sound travels at 332 metres per second through air and light can go around the world seven times in one second.
