When I started to stop motion I did not think I would do well but in the end, I think I did a lot to help. Here is our stop motion project hope you enjoy
did you like it? Ok good so now what are we going to talk about? let me think hmm oh ya here is my script. here is my set design and that is my blog post on my stop motion project see you in the next one bye.
Hi, people peacemaker here back to talk about science.
We started sound!!!! So I am going to talk about it.
The properties of sound.
what I am going to be talking about
sound can be absorbed.
sound can be modified.
sound is caused by vibration.
and here is a video of how light travel.
what are the 4 properties of sound, here’s a video hope you enjoy.
First is what is sound here is a video.
Next, how does sound travel you guessed it here is a video.
Here is a video of what is vibration.
Last but not least what is pitch?
Pitch is like the sound of your voice. if you scream it is a very loud pitch.
If you whisper it is a low pitch.
Fun fact. pitch is measured in hertz (Hz).
Finally, volume hope you enjoy it.
volume is the pitch of your voice. if you scream it is a loud volume and hurts your ears. but if you say pss that is a low volume.
Here is how a ear work above hope you enjoy.
hello people, today I am going to be talking all about light.
natural and artificial, I hope you enjoy it.
Natural and artificial light
what are natural and artificial. it is when stuff makes light that is natural light, such as a firefly and the sun. and artificial light such as a candle and a light bulb. here is a picture
and now we are going to talk about nonluminous and luminous things. luminous means objects which emit light on their own. Examples: – Sun, a flame of a burning candle. Non-luminous objects which cannot emit light on their own light. These objects reflect light from luminous bodies. Examples: – Moon, Earth.
now on to reflection, Refraction happens when light changes direction, or bends when it moves from one material to another reflection means that if you look into a mirror you see yourself because the light bounces off of the mirror. After all, it is flat and smooth.
now we are going to talk about how light travels. light mostly travels in a strate line the reason that I said mostly is because it can bend if it goes through water.
