Science News Analysis- Cars EN-V

August 26th, 2010 by joshua02pd2015 and

EN-V is a plug-in hybrid concept car that is only a two-seater. It is three times shorter than the average car on the world today and can go 40 miles without having to recharge. It can also travel at a top speed of 40 miles per hour. It has a screen where you can video talk with anyone else with an EN-V. It is made of carbon fiber, acrylic, and custom tinted plastics. It runs on lithium-ion batteries. This relates to our lives in many ways. First off, it is very small and light. This means that it can slide into tiny parking spaces. Secondly, it is very eco-friendly. Plug-in hybrid technology is just kicking off and is very efficient. All you do is go to a charging station and they sell electricity to you like selling gas. This also relates to us because it has technology similar to a phone. Most people have phones and sometimes you can even talk to each other on video. This is almost identical to EN-V technology. The EN-V relates to our lives in many ways.

Artist Statement

June 2nd, 2010 by joshua02pd2015 and

My work reflects my symbols that I made in my window to the soul project. My sculpture represents a blob of negative and positive space. This sculpture is in my opinion a total disaster. The whole thing is falling apart because it isn’t strong enough.

I used materials such as foam core, blue spray paint, magazines, Xacto knives, and glue guns. I combined these symbols because they fit nicely with each other. I chose to arrange these symbols so that it would look like some kind of futuristic city. These symbols represent my soul.

In creating this sculpture, I found that foam core is really hard to cut. I feel that my work meets all the requirements but isn’t very good. I discovered that foam core is very fragile.

Journal No.6

April 12th, 2010 by joshua02pd2015 and

I opened the box and all I found was a severed finger. There was a hunk missing which a bug had chewed off because there was a whole bug colony coming after me. The bugs were each a foot long and had a stinger six inches long. Their skin had spikes that had green dew but I knew not to mistake it. The dew causes pain that is twenty times stronger than the most painful death. The worst part is that the toxin won’t let you die. You will be immortal but you will be in pain. There were about one hundred of them coming after me. I dove into the lake and swam under water. I turned my head and saw them dive under and fins appeared on there sides. I swam to a cave and popped into air. The drone was getting louder and the first few have popped out of the water. I frantically searched the cave but I was trapped like a hog on slaughtering day. Right when I thought I would have to battle the bugs I saw an opening above. I leaped up and gripped a crevice. Then continued to climb I jumped onto the new platform and raced to the other side. I saw two paths and took the right one. It had a slight downhill slope and soon I was wading in water again. The water was green and bubbles were coming out. It was probably poison! I held my breath and dived in. I got out on the other side and ran to the next cave. The bugs died in the water. And I laughed in triumph. Then all of a sudden there was a huge splash and a giant sea snake appeared out of the water. It slithered to me and wrapped itself around me. I held onto rocks as it tried to pull me in. I slid out and started running towards the next path when three giant dogs blocked my way. All of the creatures pounced and landed on me and started hacking away. I was fighting back but after awhile I couldn’t hang on. I tried to protect my head but I knew if I didn’t escape now I’d be a goner. I kicked a dog to the side and made a dash for it. The dogs were fast runners and kept up with me. Right when I found the exit I felt a sharp pain in my back and I knew one of the dogs had found its mark and the rest will be homing in soon. I chucked the dog to the side but the other two leaped onto me. They brought me to the ground and were ripping at my throat. I kicked the dogs away when the sea snake dragged me back into the poison water. It was spinning me around and its grip was really strong. Just when I felt like I couldn’t hold my breath any longer the creature accidently ripped my arm off. I swam to the surface and started running for the surface. Using my good arm to staunch the blood flow coming from the hole in my neck. When I got to the exit a carnivorous plant grabbed me and shoved me into its mouth. I fell into a pile of sloppy grime and screamed when my arm touched the slime. The ooze went into my blood system and I could already feel myself getting weak. I destroyed the stomach of the plant and blasted out. “Yay” I said and immediately fainted.

Band SLC Reflection

April 1st, 2010 by joshua02pd2015 and

Since January we have played these pieces in band: All the Pretty Little Horses, Knife River, Portrait of a Clown, the King of Rock & Roll, T.M.I., Sunday Morning, Jazzmin Tea, Midnight Escape.

I have learnt these scales from MEMORY! (concert pitch): Bb, Eb, Ab, C, F, Db.

My favorite piece this year is: T.M.I.

Because: I have an epic solo, the music is very upbeat, and I am never bored when I play it.

My band goal for the final quarter of the year is: to play G major scale without mistakes because it has tricky fingerings.

This is the practice lab report that I did.

Gummy Bear Lab Report

By: Joshua

Purpose

The purpose of the gummy bear lab was to determine the diffusion of gummy bears in salt water.

Hypothesis

If I put gummy bears in salt water, then it will increase in size.

Materials

  • Cup
  • 1 Gummy Bears
  • 3 teaspoons of salt
  • 100 mL of water

Procedure

  1. Find a cup, 1 gummy bear, 3 teaspoons of salt, and 100 mL of water.
  2. Pour the water into the cup and add the gummy bear
  3. Wait for 48 hours.
  4. Remove the gummy bear.
  5. Measure the gummy bear.

Data Collection

Dimensions Initial Size Final Size
Length 1 centimeter 1.1 centimeter
Height 1.6 centimeter 2 centimeter
Width 1 centimeter 1.1 centimeter

It was squishier than before, the color became a little plainer, less bubbles. He easily fell apart with a light tap

Data Analysis

Vi=1.6 cm3

Vf=2.42

%change=151%

Growth of Gummy Bear in Salt Water

Explanation

Since my gummy bear increased in size that means that water diffused into the gummy bear, making it larger. The gummy bear in salt water didn’t increase as much because the concentration of  water between the gummy bear and salt solution were about the same.

Alternative Explanation: The salt may have absorbed some of the water, making less water to diffuse than before. As part of my further investigation I would like to test gummy bears in water with a lower concentration of salt.

Errors

Some possible sources of error is that I could’ve measured the gummy bear incorrectly, didn’t put enough salt, and didn’t dissolve the salt enough. Water could have been hot.

Conclusion

In this lab, I learned about diffusion in a gummy bear. My hypothesis was correct. I put the gummy bear in water and observed it after. It was squishy and had a darker color. I learned that diffusion isn’t as effective if the concentrations of two objects are similar. This lab was based on observing what happens during diffusion with gummy bears in a solution with a similar concentration of water.

Reflection

I think that I learned a lot from my practice lab report and that if we didn’t do it my grade would probably be hanging around a sixty now. There were a lot of topics that I didn’t manage to cover and I was missing many key items. My previous knowledge wouldn’t have helped me because that’s what I relied on.

This is the final product.

Gummy Bear In Cold Water

By: Joshua

Purpose

The purpose of this experiment was to compare the diffusion of two gummy bears in water of different temperatures.

What We Know

  • Water molecules move slower in the cold
  • Water molecules move faster in heat

What We Don’t Know

  • What will happen to the gummy bear in cold water

Hypothesis

If gummy bears are placed in cold water then it will increase in size but not as much as the gummy bear in room temperature water because the water molecules move slower.

Manipulated Variable

  • Temperature of water

Responding Variable

  • Size of gummy bear

Materials

  • 200 mL cup
  • 100 mL Graduated cylinder
  • 2 pink gummy bears
  • Refrigerator
  • 100 mL of distilled water

Procedure

  1. Measure out 100 mL of distilled water with a graduated cylinder
  2. Pour the water into a 200 mL cup
  3. Measure the height, length, and width of the pink gummy bear
  4. Place the gummy bear into the cup with the water in it
  5. Place the cup with the gummy bear into a refrigerator
  6. Wait for 24 hours
  7. Remove the gummy bear
  8. Measure the gummy bears height, length, and width

Data Collection

Dimensions Bear in Cold Water Bear in Warm Water
Length before 1.6 cm 1.6 cm
Width before 1 cm 1 cm
Height before 1 cm 1 cm
Volume before 0.53 cm3 0.53 cm3
Length after 2.5 cm 3 cm
Width after 1.5 cm 1.6 cm
Height after 1 cm 1.7 cm
Volume after 1.25 cm3 2.72 cm3
% change 135% 413%

Observations

I observed that it was squishier than before we put it in the water, the color became a little plainer, less bubbles were inside the gummy bear, and the gummy bear was harder than the gummy bear in water at room temperature.

Data Analysis

Equation for Volume: l x w x h = v

Percent of Growth of a Gummy Bear in Different Temperature Waters

Explanation

Since my gummy bear increased in size that means that water diffused into the gummy bear, making it larger. The cold gummy bear didn’t grow as much as the warm gummy bear because the molecules entered the cold gummy bear slower than the gummy bear in warm water. These results mean that my hypothesis was correct.

Alternative explanation: The refrigerator could have made the gummy bear so cold that it could have gotten denser making it harder for the water molecules come in.

Errors

Some possible sources of error that could have been made is that someone could have measured the temperature of the water before it was completely chilled, causing us to have incorrect measurements. It is impossible to measure the gummy bear perfectly when the time reaches the limit because humans can’t measure the smallest fraction of a measurement and even when you think you can’t get closer there will always be a number smaller.

As part of my further investigation I would like to see what happens if you put a pink gummy bear into a cup of hot water in comparison with a cup of cold water.

Conclusion

In this lab I learned about diffusion of a gummy bear in different temperatures of water. My hypothesis was correct. I placed the gummy bear in cold water and observed it after 24 hours. It was stiffer and smaller than the gummy bear in warm water, meaning it was denser. I learned that diffusion in cold fluids aren’t as affective as diffusion in warm fluids. This lab was based on observing diffusion when a gummy bear is placed in cold water.

Reflection

This lab report was really important to me because it helped me gain better knowledge for future lab reports and even though I didn’t get the best grade in the world my mistakes will help me in future lab reports.

Limerick

March 2nd, 2010 by joshua02pd2015 and

There once was a baby with a beard,

Who said “This is just what I feared.”

So he shaved and sliced,

Chopped and diced,

and that was all that he sheared.
