Hello word it is me ethant36 today I will be talking about my public speaking project.

Here is my speech:

Have you ever thought about how your emotions, your movement, your balance, your five senses and your thoughts work? Or have you ever thought about how awake and aware you are or how you move, walk, speak, swallow, breathe and learn? If you have, and if you wanted to know, then you can learn right now.

Hello grade 4 and Ms.m today I am here to talk about the nervous system. 

 

The nervous system is made up of your brain, your spinal cord and a complicated system of nerves. The nervous system controls movement and balance, the five senses (sight, hearing, taste, smell and touch), how your thoughts work, how awake and aware you are and it also lets you walk, speak, swallow, breathe, learn and it also controls the psychological “fight or flight” which is when you sense danger do you run (flight) or fight.

 

Since the nervous system controls 100% of the body, it has to be working at all times. If it’s not working, you wouldn’t be able to breathe and that would be terrible. It doesn’t work by magic though, it works like this: the brain sends signals through the spinal cord, and the signals go wherever they must like if the brain wants to tell the legs to start working the brain would send a message through the spinal cord and then the legs are like “oh I’ve got to start moving” and then it starts moving. All that happens in about 0.1 seconds! 

 

Have you ever wondered about the different parts of the brain and what they control?  Now I will talk about the telencephalon, the diencephalon, mesencephalon, the metencephalon and the myelencephalon. The first part of the brain that I will be talking about is the telencephalon. The telencephalon is the biggest part of the brain and the closest to the top. It controls sensory integration which is when you get information from your senses it says do I ignore it or do I react to that information, voluntary movement (the expression of thought through your actions) speech, and abstract thought. The telencephalon is way bigger than all the other parts of the brain. The second part of the brain that I will be talking about is the diencephalon. The diencephalon controls the body temperature, how hungry you are, how thirsty you are, fatigue (how tired and how energetic you are but has nothing to do with sleep) circadian cycles (physical and mental things that go on a 24 hour schedule) and sleep. Another part is the mesencephalon. The mesencephalon controls vision, hearing, motor control (the steps to starting and directing voluntary movement) (the last three things the diencephalon helps too) sleep, alertness and body temperature. The second last part of the brain that I will be talking about is the metencephalon. It controls the sensorimotor structure (Activities that relate to sensory and motor activity) and motor coordination. Now it’s the last part of the brain that I’ll talk about: the myelencephalon. It controls heart rate and breathing.

 

In conclusion, we learned how important the nervous system is, what it does, how it works, the different parts of the brain and what they all control. I hope that now you know how it works and how much work it has to do. When you walk you use it, when you talk you use it, when you breathe you use it, when you think you use it and really when you do anything you use it!

 

 

Hello world it is me ethant36 and today I will be doing my podcast reflection. Before you continue please go to the podcasts  of my class (my group’s was the chocolate touch talk.)
I liked the podcasting a lot. Most went very well, but the first one was not really a conversation because it was WAY too artificial. If I were to do this again, I would make the first one that we did less artificial but everything else went amazingly. The reason it was called the chocolate touch talk was because the book is called the chocolate touch. Here is somewhere where you can download the book. Thanks for reading!

Hello people it is me ethant36 and today i am going to write about my innovation day project. We were asked to make a castle with a working drawbridge. To do that you need to use a pulley. For the challenge you had to use gears. A pulley is a simple machine that is for lifting things. Pulleys help you lift things because when you are using them you don’t need to use brute force and you can use some weight. Here is a picture of a pulley

 

Compound pulleys are pulleys with more than one pulley.

Compound pulleys help be cause if the load is 100 pounds and you have two pulleys, you only need to use 50 pounds of force.

If you have three pulleys you divide the load’s weight by three and that is how much force you need to use.

Here are pictures of compound pulleys

 

Gears

Gears are technically not simple machines but they are pretty simple.

Gears are for having one gear move another one and they can move each other.

 

When one gear is being turned, that gear is called the driver gear. The gear that is being turned by the driver gear is called the follower gear.

Note how when one gear is going clockwise, the other gear is going counterclockwise.

The Idler

The Idler is when there are more than two gears and the idler is the one in the middle (if there are three gears).

The idler makes it that if the driver gear is going counterclockwise the follower gear also goes counterclockwise.

Here is an example

Ignore how gear B is in gear C.

Notice how gear A  is going clockwise, gear B/C (the idler) is going counter clockwise and the follower gear, gear D is going clockwise.

What the idler does is if the driver gear is going clockwise then the follower will too.

Since we are building a castle, we need to know about castles and what they look like and we also needed to know about the feudal system and the medieval part of things so here is my google slides about it.

 

Here is my hypothesis (How me and my partner thought we were going to build the castle)

Here is our procedure video

Final video:

Here are two pictures of my rubrics

Self reflection

My self reflection questions were What did you like/ dislike and why and what I would do differently next time. I liked the project because there was lots of building and I like building. For what I would do next time I would try to do a little more things in the inside. I liked our pulleys and gears but the inside was kind of bare.

 

Hi, it’s ethant36

Today I’m going to tell you about my stop-motion project in class. Stop motion is a lot of pictures and you watch them. If you do it well, it will look like a movie.

My task was to re-creating a scene from a book called The Wild Robot. We choose the scene when the RECOs come and attack and the first part of the battle. Here is a PDF version of the book.

We choose this scene because it included action

Pre-production: here are some pictures of the script:

Pre-production: here is a picture from the storyboard plan

Self reflection

The actual movie was good and I like it but sometimes I feel like my group did not do enough work in the time.

 

Here are pictures of my self assessments

Hello people it is me ethant36 and today I will tell you about my second science unit: sound.

What is sound?

The first thing I will tell you about is what is sound. Sound is a series of vibrations that cause sound. The 4 properties of sound are: Sound can be reflected (echoes). Sound can be absorbed, too. It is absorbed with soft materials.  Sound can be modified (speakers modify sound). Finally, sound is caused by vibrations.

                           Vibrations

You cannot always see the vibrations but they are vibrating. Sometimes with watches you can make it vibrate (you can feel that sometimes!) but if it is making sound it is vibrating. One fun experiment: The materials you need are sour cream container or anything like it, tuning fork, salt, plastic wrap, rubber band, and water. Instructions: 1. put the plastic wrap over the container tightly with the rubber band.

                           Absorbing sound

Here is a picture of a recording room. The foam absorbs the sound so there is almost no echo. The foam on the wall is amazing for absorbing sound. They do not want movies to sound weird.

Echoes

Echoes are sound being reflected. Echoes bounce of of surfaces and you can sometimes hear the word again. Concrete and hard materials like it echo more than soft materials, which absorb sound.

Pitch

Pitch is how high the sound is. It is measured in Hertz (Hz) humans can hear sounds from 20hz to 20 000hz. Dogs can hear higher sounds than humans which is why humans can not hear. Dolphins and bats can hear even higher sound than dogs.

 

               Here is a picture of my model ear:

Here is a video on how ears work

 

 

 

 

 

 

 

Volume

Volume is how loud a sound is. Volume is measured in decibels (dB). A whisper is about 30dB a normal voice is about 60 dB and a scream is about 120dB. If people are around noises over 90dB all the time their hearing can be damaged and if a human hears a sound over 130dB their hearing can be damaged immediately.

 

Reflection of learning

I liked the sound unit and I liked the experiment.

 

Hope you liked it!

 

 

 

Hello people it is me ethant36 and today I will tell you about my first unit in science, light.

Our first thing was natural vs artificial light and then luminous (object that makes its own light) and non luminous (object that can’t make its own light)  and their meaning.

Then we did an experiment about how light travels. The point of the experiment was to find out if light travels in straight lines.

Then we learned about reflecting light and which materials are good reflectors. We learned what secular (smooth and good for reflecting) and diffuse (Bumpy and bad for reflecting)mean and transparent, translucent and opaque meanings and then refraction (where light appears to be somewhere that it is not because light moves more slowly in water than air). That was our first science unit that we did in grade four. 

Here is what I learned:  I learned about refraction, how light travels, and reflection.

For our next science unit  I want to learn about simple machines.

Science is fun! 

Here are some pictures of experiments 

 

One Saturday, I had a playdate with my friend Jonas. 

Before Jonas came, I was coming home from soccer and we were worried that Jonas would get to my house before we got home from Carleton. When we came home and found out that Jonas was not already at our house, we were relieved.

First, Jonas drove over to my house and we played frisbee on the lawn,  but after that, we all decided to go to the park and it is a five minute walk.

The shoes we were wearing were not good for the park, Which is why we went inside to change our shoes and socks because I was wearing crocs and no socks and Jonas was wearing new, white shoes. 

Then since we both put on running shoes,  we went to Mckellar park and we played frisbee, did an obstacle course, played on the swings, and then we went back home and had banana bread for a snack because we were hungry.

Next, we played in my basement with a ball because we have pretty much nothing in the basement (we just moved in a little more than a month ago). 

Then, I showed Jonas a website called Chess.com. 

After that, we went back downstairs and then we had chicken balls, pasta, cold salmon and potatoes for dinner. 

Finally, Jonas went home. 

That was a fun day!
