In Science we used drums, rice, marshmallows, beans and salt to answer the following question. 'Can sound waves be seen as well as heard?' Comment below on what you learnt, what you enjoyed or any new questions you now have.
You cannot hear with your eyes. The rice danced more than the beans Mrs Govender because they are lighter than the beans. I enjoyed everything about this experiment.
I agree with Flynn, the rice danced because they were lighter than the beans, but Mrs Govender, can you see sound waves when a supersonic jet breaks the sound barrier?
Sound waves cannot be seen. I really enjoyed being a scientist and experimenting with different sounds. My mummy also taught me that my dog Charlie can hear sound at a higher frequency. That’s why Charlie can hear noises that I can’t.
No Mrs Govender, sound waves can not be seen with your eyes, but it can definitely be heard with your ears. Being a scientist in the classroom was very exciting, because i enjoyed experimenting with sound using various food and materials.
Can anyone answer this question? "How is sound measured"?
Wow year 2. I think you have all become quite the scientists. I am very impressed by your responses.
I like the way that some of you have been discussing this at home with your family, are asking more questions and are discovering more information.
Like Benjamin C said, the rice danced because when you banged the drum it created a vibration. Vibrations (sound waves) travel through the air. You can’t see them but you can see their effect.
When we banged the drum, the glad wrap was hit by the sound waves, it vibrated which made the rice ‘dance’.
the rice danced more than the salt, marshmallows and beans because the rice was the lightest. I had lots of fun with the drums. I enjoyed that science experiment a lot. Thanks to miss Natoli and mrs govender
Sound can be heard as well as seen. When you said that we were going to do an experiment I thought you were joking about it but when you showed the marshmallows, salt, rice and beans I was shocked with glee. The experiment was very fun. The marshmallows and rice were dancing because the vibrations were making the foil dance up and down and the marshmallow and rice were responding. But the beans and salt were dead. They were dead because the plastic on the tin was not moving up and down. The sound was heard as sound goes through the outer ear into the ear canal. It goes to the ear drum and the three little bones called the anvil, the hammer and the stirrup carry the noise to the cochlear. The cochlear has little nerves which send the sound to the brain. The brain figures out what that sound was or where it was coming from. The brain figures out if it was an emergency, someone speaking to them or someone hurt and the sound goes through the ear parts in less than one second. It was fun doing experiment. I hope we do more like that. Thank you Miss Natoli and Mrs Govender for the experiment. Darcy Hill [all Darcy's words - typed by Mum]
No. Sound waves can not be seen as well as heard, at least that is what I think. I loved doing the experiment and being a scientist. Yah, I'm a scientist.
What I learnt... I learnt that marshmallows, beans and salt can not shake, even when you bang a drum, but rice can dance a little. I liked to bang the drum and learn to shake the ingredients. Sound waves can not be seen, but can be heard. [typed by Charli, written by Charli].
Sound is like messages that travel to your ear, sound waves vibrate whilst travelling to your ear but you can't see the sound waves. Sound waves can make things move back and forth but you still can't see the sound waves. Like in our experiment the rice danced on the plastic wrap when the drum was going.
If you flicked a glass bottle in space, you wouldn't hear it because you need air for the sound waves to travel along and in space there is no air.
Sound waves cannot be seen as well as heard mrs govender and miss Natoli 👧😺I think the rice danced more than the marshmallows,and the salt and also the beans
When you said can sound waves be seen as well as heard I didn't know how they could be seen:D I watched very closely but I could not see any sound waves and then I saw the rice dance a bit and the I got louder and it moved lots:D then I tried the next thing! I saw it move I tiny bit but not as much:/ then I tried the other things but the only one that did not work was the beans :( so then I defintly knew that the rice danced a lot more! Then the salt were 2nd then the marshmallows were 3rd and the beans were fourth
I loved the experiment because I could see that the rice was dancing and because it was really fun seeing the rice moved it was unbeliveible that it actullay danced!
I enjoyed the drums because I wanted to see if I could see sound waves but I couldn't. I liked researching sound waves and found out that the speed of sound is 1,230 kms per hour. The loud noise you make by cracking a whip happens because the tip is moving so fast it breaks the speed of sound. Sound comes from vibrstions, which move through air and water and granite and steel before getting to our ears.
i know that sound waves can not be seen as heard. sound is so invisible . when i go to singing concerts where i perform i can not see the sound waves. in science me and the table found out that all out of ,rice,marshmellows,beans and salt that it will dance love jaida pj.
Sound can not be seen, just heard. But you can see the vibrations. The rice bounced more because it was lighter. When I got home I did the experiment for my mum and dad and it worked.
No the marshmallows, beans and salt didn't dance because they tried all the drums but it didn't work. Then the rice did dance because they tried all the drums and made them louder and this made it dance. We cannot see sound waves but we can see the vibrations when they get louder.
No, sound waves cannot be seen because they are invisible. The dancing beans and marshmallows was the effect the sound waves had on them. We didn't actually SEE the sound waves.
I had lots of fun doing this experiment. I learnt that sound cannot be seen as well as heard. In our experiment the rice, beans, salt and marshmallows all moved, the marshmallows moved the most. The vibrations of us hitting the drum made the movement.
You can see what is making the sound but you cannot see the sound waves with your eyes. I loved doing this experiment but the beans, salt, rice and marshmallows only danced to the beat of the drum the sound waves did not make them dance.
it was fun making the sound moving waves with the drum. i loved it we get to play the drums.we saw how making vibrations with the drums made things we placed on top of it move. the rice moved the most. the beans did not move.
No we could not see the sound waves made by the drum but we saw things moved by the sound waves. Yes the rice danced more than the beans, salt and marshmallows because the rice grains are lighter. I really enjoyed the Science experiment. It was very interesting and lots of fun. I expected that none of them would dance.
Year 2,
ReplyDeleteLooking forward to reading your posts this week.
Mrs Govender
Did the rice dance more than the beans, salt and marshmallows? If so, why do you think they did?
ReplyDeleteNo, because our eyes are not able to detect sound waves, that is why we have ears which can detect sound. I liked this activity because it was fun!
ReplyDeleteThats right harry we cant hear sound with our eyes.
ReplyDeleteYes Harry & Nathan I agree with you.
ReplyDeleteHowever, sometimes loud sounds can create vibrations that we cam see with our eyes.
I also agree Harry Nathan and Ben c

ReplyDeleteThe rice danced more than the beans, salt and marshmallows, because it was is the lightest. It was fun! i can't to do another experiment.
ReplyDeleteSound waves cannot be seen. I really enjoyed being a scientist and experimenting with different sounds. My mummy also taught me that my dog Charlie can hear sound at a higher frequency. That’s why Charlie can hear noises that I can’t.
ReplyDeleteDo you think that this could be why my dog Pebbles sometimes barks for no reason Annabelle? Miss Natoli
DeleteYes it is Miss Natoli. If we didn't know that they can hear sound at a higher frequency, we would just think they are crazy for barking for no reason.
DeleteNo Mrs Govender, sound waves can not be seen with your eyes, but it can definitely be heard with your ears. Being a scientist in the classroom was very exciting, because i enjoyed experimenting with sound using various food and materials.
ReplyDeleteCan anyone answer this question? "How is sound measured"?
Great question George! I can't wait to see what other people respond with.
Deleteyou can not see sound waves.
ReplyDeletebut you can hear them.
yes i did like the experiment.
my question is how does it make the rice and beans move?

ReplyDeleteI loved the experiment thank you for letting us do it miss natoli and mrs govender!!!!! It was so funny when the rice danced!
ReplyDeleteSound waves can not be seen but they can be heard,the rice danced more then the marshmallows,i really liked this experiment.
ReplyDeleteI agree Jonny
DeleteI agree Jonny and Kathryn
DeleteI Love the experiment activity as it is through that I can learn about how things work and learn how to drum as we were using drums.
ReplyDeleteI loved the experiment because I could see that the rice was dancing and because it was really fun seeing the rice moved it was unbeliveible that it actullay danced!
DeleteI wonder how the sound travels sooooooooooooo fast in half a second!

It was a fun experiment and we got to play the drums to see how how different things moved with sound waves.
ReplyDeleteit was fun making the sound moving waves with the drum. i loved it we get to play the drums.we saw how making vibrations with the drums made things we placed on top of it move. the rice moved the most. the beans did not move.
ReplyDeleteSound waves can be heard but not seen. In our experiment we could see objects move caused by sound waves using drums.
ReplyDeleteNo we could not see the sound waves made by the drum but we saw things moved by the sound waves.
ReplyDeleteYes the rice danced more than the beans, salt and marshmallows because the rice grains are lighter.
I really enjoyed the Science experiment. It was very interesting and lots of fun.

You cant see sound waves but you can hear them😆
ReplyDeleteI agree with that Emily
ReplyDeletei agree with everyone. Everyone has great answers!!
ReplyDeleteI had fun at the aquarium. My favourite sea creature i saw was the dugong.
