Innovation Day Reflection

Hi. It’s Shayna. I am going to tell you about what happened and what me and my group did. I worked with Minecraftman1 and Noa.

What’s the point of making an innovation day project if you don’t even have a reason? We had to do our project for a reason. We were asked: how can we provide electricity to community outdoor spaces using solar energy that still maintains the safety and “fun” asthetic of the space? Our hypothesis was :We thought if our solar-powered street light works, then it would be better for the environment because it won’t use fossil fuels to power the lights. We used Cardboard, hot glue, markers, glue sticks, aluminum foil, a tri-fold poster board, paper and a LOT of work. We made a solar powered street light with a photovoltaic solar panel. Our solar power street light would charge during the day and light up at night. We thought if our solar-powered street light works, then it would be better for the environment because it won’t use fossil fuels to power the lights. We made a great team. We listened to eachothers ideas and we made sure everyone in our group was okay with a decision we made before doing it. In the end, we all did a great job and everyone loved the presentation. We could have made our project a little bigger, and use more websites, a s well as doing a tad more research, but I think our project turned out AMAZING and UNIQUE. Here is a picture of our project:

Have a good day! Byeee!

Innovation Day

Introduction

Good day, people! Today I am going to tell you about my innovation day project. We were asked to build a castle with a mechanical/working drawbridge. I will also tell you about the middle ages (Medieval Times).

Castles

If there’s one thing I know about castles, they are really uncomfortable. There were a lot of kings, queens, and nobles who lived in castles. Castles provided protection. There were also safe areas to store weapons and food supplies. The first castles were just wooden forts to keep soldiers safe in enemy territory, but after they started building castles made of stone. By today’s standards, life in a castle wasn’t very nice. Castles were cold and gloomy. Castles are designed to have protection and not comfort. A lot of castles only had a few rooms. There was a great hall, a kitchen, and two or three chambers/rooms for the lord and his family. No bathrooms, just a tiny alcove that jutted out of the castle walls. The contents of the toilet emptied into the moat or a pit. Imagine how bad that would smell! Castle walls would sometimes enclose a chunk of tiny buildings. Here is a picture of a medieval castle.

Fun Facts!

  1. Did you know that castles had their water supply within the walls? I didn’t realize it until now!
  2. Did you know that some castles had moats? Moats are trenches filled with water.
  3. Did you know that in medieval times, people would chew food for the king to eat? Gross!

 

The Feudal System

I have a question for you. What was the feudal system aka feudalism in the middle ages? I knew you couldn’t answer that. I’ll answer that for you. The feudal system aka feudalism is a type of social system in which landholders provide land to people in exchange for their loyalty and service.

Epic World History: European Feudalism

 

 

 

How Does The Feudal System Work?

The feudal system was the medieval model of government predating the birth of the modern nation-state. It was a set of legal and military customs in medieval Europe that flourished between the 9th and 15th centuries.

 

 

Lords And Serfs

Lords and serfs are basically opposites. A lord gets a lot of respect while serfs are on the streets. The lords are at the top of the feudal system and the serfs are at the bottom. Lords can sit back and relax while the serfs have to work really hard for money and dinner on their plates.

 

Planning booklet

We needed to plan for how to make the working drawbridge, so Ms. M gave us planning booklets so we could learn about pulleys and gears and plan how to make our drawbridge. There were different sections in the booklet. Pulleys, gears, drawbridge planning, castle designing, and a checklist for our blog post. Here are some pictures from my booklet.

 

 

What Are Pulleys?

Pulleys are wheels that carry a flexible rope, cord, cable, chain, or belt on their rim. Pulleys are used singly or in combination to transmit energy and motion. There are two different types of pulleys. Fixed pulleys and movable pulleys. If there are two or more pulleys, it will become a pulley system. The more pulleys you put in a pulley system, the less weight you carry.

 

 

What Are Gears?

gears are wheels and axles that have teeth along their wheel. They are primarily used in combination with one another and change the direction of forces. The size of the gear determines the speed at which it rotates. Gears are mainly used to increase the force or speed of a machine.

This is a picture of a gear system.

 

How Do Pulleys And Gears Work?

Pulleys are made by looping a rope over one or more wheels. They are mostly used to lift heavy objects or weights. pulling down on one end of the rope creates an upward pull at the other end. Looping the rope over more wheels increases the upward force.

Gears are wheels with teeth that slot together. When one gear is turned, the other one turns as well. If the gears are of different sizes, they can increase the power of a turning force. The smaller wheel turns more quickly but with less force, while the bigger one turns more slowly with more force.

 

 

Hypothesis For Innovation Day

We were asked to make a castle with a working drawbridge from the middle ages/medieval times. I thought that I would use a gear and it would be connected to the castle. I thought the gear would be connected to a pole/skewer and a rope connected to the pole/skewer. I would use the rope and attach it to the drawbridge, but my group and I had to use two gears on each side and attach a piece of cardboard to each side so we would be able to keep the gear and pulley system steady.

 

 

Procedure

Here is a video of me, Livia, and Nikki’s procedure:

 

Final Results:

Unfortunately, I couldn’t make it to Innovation Day, but I heard it turned out to be absolutely fabulous!

Self Assessment:

WWW (What Went Well?)

In my opinion, the pulley and gear systems in the castle were impressive.

What Could I Have Done To Make It Better?

I feel that the interior and exterior could have been improved.

All About Sound

All About Sound

Hi! It’s Shayna back with another blog post. Today were going to talk about sound.

 

What Is Sound?

Sound is energy we can hear.

Four Properties Of Sound

here are the four properties of sound:

  1. Sound can travel.
  2. Sound can be reflected. (can bounce of of surfaces.)
  3. Sound can get absorbed. (Doesn’t be bounced off some things.)
  4. Sound can be modified (Pitch and volume)

Here is a picture of sound waves.

Here is a video of What Is Sound?

 

What Are Vibrations?

Vibrations are sound waves that travel through our ears.

Vibration Experiment

In our experiment we experimented vibrations.

As you can see in the experiment, We used tuning forks and we tested vibrations.

 

What Is Pitch?

Pitch Refers to how high or low a sound really is. A whistle makes a high pitch sound and a trombone makes a low pitch sound. Pitch is measured in Hertz. Hz for short. Hz means that a sound wave would reach your ear every second. People can hear from 20 hz up to 20 000 hz.

What Is Volume?

The definition of volume is ho loud or how quiet something is. A whisper is quiet and a scream is loud.volume is measured is decibels and db for short. A whisper is around 30 db an a scream is around  120 db. A regular voice is around 60 db if your around sounds over 90 db all the time your hearing will be damaged. If you hear something over 130 db your hearing will instantly be damaged. That is why is is super important to protect your ears. You can’t protect your ears by going to quiet places.

Human Ear

Here is a video of how our ears work:

 

Reflection of Learning:

What did I enjoy most about this unit and why?

I really enjoyed writing the blog post about sound, and making the model ear because I like to write, and modeling is fun in my opinion.

What would I do better next time?

I think I could have added more pictures and videos to my blog post. There is only one picture and two Videos in this blog post.

What would I like to know more about?

I would really like to do a blog post about the human body and how our body’s work.

 

Conclusion

Thank you for reading my blog post! I hope you enjoyed and have an amazing day! Bye!

About Light 2022

Hi, I’m Shayna. Today I’m going to tell you about my first science unit investigating light.

 

First, we learned about natural and artificial light. Natural light is light that is NATURAL, literally in the name. Artificial light is light that was man-made.

Now I’m going to talk about luminous and nonluminous. When an object emits light it’s called luminous and when an object reflects light from different types of light is called nonluminous. Here is a picture of my work.

 

 

What happens if something blocking the travel path of light? (Also Transparent, Translucent, and opaque)

It depends if the object is transparent, translucent, or opaque. Wait a minute?! I haven’t told you about transparent, translucent, and opaque! Before I tell you, by the way if an object is opaque, and something blocking the travel path of light, it will form a shadow. If the object is Transparent or Translucent, the light will go through the object. Now I will tell you about transparent, translucent, and opaque. You probably don’t understand what I’m saying. Transparent is when there is an object that you can see through. For example, Glass is transparent. You look out your glass window every day. Translucent is when there is an object that you can kind of see through the object. For example, an empty bottle of wine, or a stained window. You can only see a little bit through the object. Now for opaque. Opaque is when there is an object that you completely can’t see through. for example, every day toys like stuffed animals, toy cars, etc..  Here is a GIANT picture of my transparent, translucent, and opaque window.

Reflection

Reflection is when light bounces of of a surface. Here is an example picture of a reflective object. gold floral frame on white textileThis is a mirror. This mirror is made for reflecting.

 

Refraction

Refraction is when light bends. For example, in this picture I have a cup of water, and I put a pencil in the it. The light bends when the pencil is in the water. Light travels slower in water. Look at the pencil. the pencil is bigger in the water and when the pencil is out of the water the pencil is smaller.

 

Reflection Of Learning

So far I think I am doing a great job in science!  I want to improve a lot this year. I am so exited to learn more through out the year! I think this year is going really well. I got my first science quiz, my math quiz, and my French quizzes. I think all of the subjects are going well. I would really like to learn about the human body later this year.

 

That concludes my post.
