Objects that know when they are touched

Touche is a new device that senses when objectss are touched. This works on humans, screens, liquids, and everday objects. Basically, it means everything. Touche requires a single wire to be attached in order to catch the movement. For example, a door knob will know whether to open or not based on how its being gripped. This new device is amazing because it'll keep you safe. Touché is a form of capacitive touch sensing, the same principle underlying the types of touchscreens used in most smartphones. But instead of sensing electrical signals at a single frequency, like the typical touchscreen, Touché monitors capacitive signals across a broad range of frequencies. Touche may enable us from key boards to computers one day. Touche is really cool because its basically another way of keeping yourself safe and monitored. Touche will lock doors depending on the grip and in the video I watched Touche is teaching kids how to eat with the proppar utensil. It buzzes when the wrong utensil is used and says "good job" when the correct utensil is used. This invention is really cool and I would love to be able to have the use of it.

Heating Earth's Surface Lab

PURPOSE: The purpose of this lab was to see what the heat did to the sand and water. It was to see which one heated faster. HYPOTHESIS: The water temperature is to get warm and level is to increase. Also, the sand temperature is to get warmer and the level is to rise. MATERIALS:2 thermometers or temperature probes, 2 beakers, 400 mL, water, 300mL, metric ruler, string, ring stand and two ring clamps, sand, 300mL, lamp with 150-W bulb, clock or stopwatch, and graph paper. PROCEDURE: !) put 2 filled beakers of water(300 mL), and sand(300mL) separatly on the ring stand. 2) Then, use the clamp to get the lamp/bulb over the beakers. 3) turn on the lamp by plugging it into an outlet. 4) Attatch 2 pieces of string coming down the ring stand. 5) take 2 thermometers and hang on on each piece of string so that one is touching the water and the other is touching the sand. 6) measure how high the water and sand are going after a few minutes witha metric ruler. 7) use clock or stopwatch to time yourself when to measure the water and sand. 8) record your results in the packet. 9) After packet is complete, make a line graph showing the increase in height. 10) follow the instuctions and start the lab report. RESULTS: There were changes during the procedure. The water and sand levels increased a lot from what they originally were. The sand level increased more than the water did. Temperature with Lights On(C) Time(min).sand......water Start 1) 2 degrees C..... 2 degrees C 2)2.3 degree C.....2.2 degrees C 3) 2.4 degrees C....2.2 degrees C 4) 2.4 degrees C....2.2 degrees C 5) 2.4 degrees C....2.2 degrees C 6) 2.4 degrees C....2.2 degrees C 7) 2.4 degrees C....2.2 degrees C 8) 2.4 degrees C....2.3 degrees C 9) 2.4 degrres C....2.3 degrees C 10) 2.5 degrres C....2.3 degrees C 11) 2.5 degrees C....2.3 degrees C 12) 2.5 degrees C....2.3 degrees C 13) 2.5 degrees C....2.3 degrees C 14) 2.5 degrees C....2.3 degrees C 15) 2.6 degrees C....2.3 degrees C ^^SAND ^^WATER Temperature with Lights Off(C) Time(min) SAND.........WATER 16) 2.6 degrees C......2.3 degrees C 17) 2.6 degrees C......2.3 degrees C 18)2.6 degrees C......2.3 degrees C 19)2.6 degrees C......2.4 degrees C 20) 21) 22) 23) 24) 25) 26) 27) 28) 29) 30)^^ SAND..............^^WATER (MY GROUP DID NOT HAVE ENOUGH TIME TO FINISH THE DATA TABLE). CONCLUSION: During this lab, the water and sand temperature to get warmer and the level to to increase was expected. This is exactly what happened. The sand temperature was warmer and the level also increased more than the water. The surface layers of water and sand get heated directly by the sunlight. If none of this heat is conducted away, the sand will reach a higher temperature than water because of the lower specific heat. However, the heat does get conducted away. But again, since it is conducted away more slowly by the sand, than by the water, the surface of the sand stays hotter. This is why the sand is warmer than the water. The purpose of the lab was to if the water or sand got warmer. Also, to see which one increased in height more. This was a fun lab and we should do more of them.

USING MAGNETIC BACTERIA TO CONSTRUCT THE BIOCOMPUTER OF THE FUTURE

This is magnetic bacteria. The article I read was about Magnetic Bacteria. This will help later in the future with the technology then. The main idea was the parts in the computer are decreasing in size and its become very difficult when it comes to manufacturing the computer. This problem is making prices increase. With the new Magnetic Bacteria, there will be less computer parts and prices will go down for sure. All of this research was done in the UK and Tokyo University of Algerculture and Technology. To me, this is an amazing idea!Who would'nt want to pay less for getting their computers manufactured? These products don't harm your computer at all because they are natural, coming from the earth. Researchers are now growing tiny magnets that can serve as components in the minuscule hard drives in the future. These Magnetic Bacterias can even help human beings with surgeries or even live permenantly inside the human body. The Magnetic Bacteria is a great idea.

Current Events

In class, we were assigned to print out a science related article. My article has to do with the worlds largest radio telescope, the Square Kilometer Array(SKA). This article was about extratterrestrial life may being detected by Square Kilometer Array telescope. Also, 3,000 dishes will be used to spread over South Africa and Australia. This is bidding to host the project will which will start in 2016. There is a possibility that this will take place in South Africa and Australia. This construction is supposed to start in 2016. This happend to uncover the secrets of the history and future of the universe. This is a great way to learn more about the world!

I feel strongly towards this article. I think it a good idea. It will help us discover more about our history and what might be coming in the future. The telescope will shed new light on dark matter, blackholes, stars, and galaxies. This is awesome because we will discover things we never did before. Also, alien life might be detected. It would be cool if scientist discoverd that there are aliens. It will involve twenty countries and seventy institutes. It will provide a tremendous amount of data. This is benefitial because science teachers will have more to teach and students will have more knowledge. It's attracted a lot of young people into science and math in Africa. It's always good to learn knew things and it's great that Africa is taking an interest in learning more.

Changes of Matter

 Last week we worked on a lab which included physical and chemical change. We worked on four different  labs. We worked on two candles; one small and one big, a marshmallow, and a sugar cubes. All these labs had some chemical changes and some physical changes. 

This is an example of chemical change.

This is an example of physical change.

       The small candle was the first lab we did. In this lab, we watched the candle burn down and melt. You were clearly able to see the wax dripping down the candle. When the candle was not put on fire, it was a  physical change. When we set it on fire, it became chemical change. Next, we lit a bigger candle. For this candle, we mixed several substances together and poured it over the big candle and it instantly blew out. This was one of my favorites because I have never seen anything like it before. Again, just like the little candle when this candle was not lit it was a physical change. When it got lit, it became chemical change.

This picture shows a big and small lit candle.

       The next lab was burning the marshmallow. In this lab, we had to taste the marshmallow before it was burnt and after it was burnt. Before it was burnt, it was physical change. After it was burnt, it was chemical change. Before I burnt it, the marshmallow had a sweet taste and soft feeling. After I burnt it over the bunsen burner, it tasted burned and it became crispy. The original white color of the marshmallow was gone. It was dark brown, almost black. This happened because I left mine on the fire for a longer time. This was my favorite lab because we got to eat it. It reminded me of s'mores. I really enjoyed this lab. 

This is how my marshmallow looked after I roasted it over the bunsen burner.

      Finally, comes the sugar cube lab. We crushed two of the four sugar cubes and poured it into the test tube. Then our group put the test tubes with the sugar over the bunsen burner. It was boiling and caramelizing the sugar. Then, all of a sudden the sugar came up like it was going to explode. We turned off the bunsen burner and took the tongs and put the test tubes down. The sugar was totally burnt just like the marshmallow. The sugar would not come out of the test tube. The test tube was broken apart and   we tasted the burnt sugar. It tasted really bad. Although, this was not my favorite lab it taught me a lot. This can help me in the future when I cook. 

This picture shows burnt sugar.

        All in all, these labs all had a purpose to them. It was to show us the states of matter. It showed us physical and chemical changes. All the labs had to do with fire. The marshmallow and sugar lab were similar in my opinion. They both started out as white. Then they turned burnt which made them brown/black. I enjoyed all these labs and I hope we get to do something like this again.

Separating Mixtures Procedure

Step 1: Take out all substances other than water with a spoon, and put them to the side.

Step 2: Pour the water into the beaker.

Step 3: Use the magnet to take out the iron from the other substances. 

Step 5: Put the beaker with water onto the hot plate and plug it in into an outlet.

Step 6: After the water starts to boil you should see the secret ingredient(salt). 

Step 7: Carefully, take your tongs and pick up the hot beaker from the top and put it on the table. Make sure the table is meant of science. The hot beaker can burn plastic.

Step 8: After the liquid cools down, pour it into the graduated cylinder.

Step 9: Put the filter paper on the funnel and pour the water through it into the beaker.

Step 10: By now, you should be able to see the salt for sure.

Step 11: Record all your steps, so that you can share them with your group if they missed any.

Step 12: Clean up! Make sure it's as clean for the next group as it was for you. Try not to break anything!

Extra Credit #3

“Education is the key to unlock the golden door of freedom”

        The quote above can mean many things. To me it means if you get proper education, you will get all the freedom in the world because you know whats going on and what you need. In life, you are nothing without education. If you are not educated people can use you. Also, when you go shopping and if you get the wrong change back, you will not realize it. Education is the key to success. You will make the money you do with education you have. This is what the quote means to me.

Frog Dissection

Yesterday, In class I dissected a female frog. This showed us how the inside of our human body looks. I learned that if the human and the frog have the same part, they have the same function. For example, the stomach in both of our bodies has the same function. This function is the break down food in the process of digestion. The liver produces bile in both of our bodies. Although, the stench was gross, I learned a handful. Also, because we got a female frog, we had to remove the eggs. I thought that the eggs would be in little clumps in certain areas, but they were through out the entire frog! It took a while to take out, but you need to in order to see all the other organs because the eggs are covering them. I thought the liver was really cool. It was three different sections. I thought it would be just one. My group also opened the mouth and took the tongue out! I imagined all frogs having the long tongue to catch flies. This frog had a human shaped tongue in a smaller size. I know that the frogs food had digested or the frog had not eaten any food because when we cut open the stomach it was empty. I actually wanted something to be in the stomach so that I could see what the frog we dissected liked to eat. I feel that this frog dissecting lab was very helpful. Now I get a better understanding of what the inside of my body looks like. All in all, I would love to dissect another frog to see if there are any differences in it.

Also, while doing this lab, my emotions about the frog changed several times. When we first got the frog, I thought I was going to throw up. The stench of the frog was so strong. When we cut open the frog, it was filled with eggs. It looked gross because it looked like there were little bugs in the frog. That part scared me. I disgusted when we had to take the eggs out. They were gewy and stuck to each other. They were all over the frog. I thought the liver was really cool. It reminded me of a shamrock because of the three parts. I imagined the heart to be much bigger than it was. That surprised me. I thought it would be as big as the stomach was. Speaking of stomach, there was nothing in our frogs stomach when we opened it. This dissapointed me. In conclusion, this lab was really cool and fun. It's a great way to learn about the human body! I would not mind dissecting another animal.

Presentation 1

As the Stomach Churns Paragraph

       In class, we worked on a lab which taught us how our stomach worked. We labeled four different tubes from A-D on day one. We put pepsin, a meat tenderizer, and hydrochloric acid in the test tubes. On day two, we observed the test tubes to see the changes that happened over-night. We took a straw and poked each test tube with it and then swiped the straw on litmus to see what color the paper turned. For test tubes for two of the four test tubes, nothing changed. For the other two test tubes the products in the test tubes changed the litmus to a pink color. This is because these were the test tubes that had hydrochloric acid in them. This lab shows how our stomach works. The digestive system is very slow. It is able to break down food we eat with enzymes and acids. This is what we have been learning for the past two days in the lab.

Chicken Wing Blog

         In science class, we did an experiment by dissecting a chicken wing. We saw how the wing stretches out when a muscle is pulled. We saw the fats in the chicken. The fats keep the chicken warm when its cold. While the chicken was dissected we saw the cartilage, bone marrow and the ligament. Chickens have many things in common with us. We both have muscle, fat, bone marrow and many other things. We barely have anything not in common. Chickens have wings, and we don't. The dissection did gross  me out  a little but I learned many things in this lab.

Diffusion Lab paragraph

     The diffusion lab was very interesting. Our group learned many new things. The group found a few difficulties to the lab. The classes first and second try was unsuccessful. The third try worked better. The purpose of this lab was to  observe the diffusion, which is the process by which molecules move from an area of higher concentration. My group found that the substance was isotonic. This means, its equal in the solution combination. We also, diluted the cornstarch with water and made the liquid thinner so that it was a water consistency. Then the group put the cornstarch in with the iodine. The substance became purple. The molecules were very concentrated in the baggie. they all combined and made purple water. The word concentrated is a place where lots of molecules are impacted. Basically, this means that the indicator changed color to purple. The iodine was hyper tonic, which means there was more iodine than cornstarch and the water mixture, which makes the water and cornstarch hypo tonic, which is less than. This was the purpose of the Diffusion Lab.
     Next, in this lab water, iodine, and cornstarch were implied. The water was used to put in the iodine. The iodine was used to put in the water to change the color of the cornstarch. The cornstarch was used to show what happened to the iodine and the cornstarch. The cornstarch turned purple and the water became normal color, clear. The water became a yellow orange color. the cornstarch and water mixture became a purple color. In the teachers lab, the iodine had all gone into the cornstarch and water mixture. The water then was normal, clear. This was the analyzes of the Diffusion Lab.
      Then, this lab has made a few connections to life. One connection is that when you mix Kool-Aid into water, the molecules mix together freely. This is just like when the water, cornstarch and the iodine was mixed together. Another example is when sweat evaporates into the skin and the water diffuses into the atmosphere. Next, oxygen diffuses from the air sacs in your lungs into your blood capillary. Lastly, when you bake and when the aroma hits your nose the molecules have gone into the air. This is how you  can smell the food your baking. These are some life connections. This is what the Diffusion Lab was.

Lab

     During the Diffusion Lab, I noticed many things and had a few questions as well. A question I have is, why did the iodine make the cornstarch a light purple color? What caused it? Something I learned during this lab is, that we were unsuccessful on our first try, so what was the cause of that? When we did it a second time, it worked better. These were some of the things I wondered and discovered during the Diffusion Lab.

Chemical Suspected in Cancer Is in Baby Products

        Over thirty years after chemical flame retardants were removed from children's pajamas because they were suspected of being carcinogens. More research shows that a chemical is prevalent in baby products that have polyurethane foam including nursing pillows, car seats and highchairs. The research does not tell if the chemical has been absorbed by children. But it does tell that researchers suggest that infants who use the products have higher exposure to the chemical than the government recommends. They found chlorinated Tris, in children’s pajamas in the 1970s. Although, it was not banned at the time. The Consumer Product Safety Commission now says that it “may pose a significant health risk to consumers.” Researchers found that 1/3 of baby products were tested and contained chlorinated Tris.  Eighty of the products had chemical flame retardants of some kind. Some are considered toxic, but legal to use. Among the products examined were changing table pads, sleep positioners, portable mattresses, baby carriers, rocking chairs and highchairs.  Fourteen products had the flame retardant TCEP, which the State of California describes as a cancer. It got banned in many countries, but not the United States but some states including New York. Overall toxic chemicals  are in our homes at high levels; and right now, people don’t know much about it. California standard, passed in 1975, requires that polyurethane foam in upholstered furniture be able to withstand an open flame for 12 seconds without catching fire. It's becoming much better.

Black Bears

   The study has found that black bears have only killed sixty-three (63) people over the United States through Canada in the past 109 years. Bears that kill are not always mothers who are trying to save their cubs. Most of the time bears attack you because there looking for a prey to eat. Ninety-two percent of those bears are male. However, when a mother bear feels threatened the will get aggressive. They make loud sounds and they they swat the ground with their paws and run at people. They try to make you think that they will eat you but they usually stop. It tests you out as a possible prey item. It follows you like a lion. Eighty-six percent of attacks occurred 1960-2009. Not as many bears are there today to come and attack you.

This is a bear about to attack

Toothpick Fish Analysys

Toothpick Fish Analysys

         I took and analyzed data for the four generations. In the first generation, I had eight green fish, one red fish and three orange fish. In the second generation, I had seven green fish, one red fish, one yellow fish and three orange fish. In the third generation, I had six green fish, one red fish, one yellow fish and three orange fish. In the fourth generation, where there was the environmental disaster I had seven green fish, one red fish and three orange fish. The population changed bacause in the environment that these fish live in, it is green where the green fish can easlily camouflage. The red and orange fish hide very well in the colors of algae and seaweed. Sadly, the yellow fish can be seen by their predetors and are eaten. The fish that are dead get put into the morgue. Because these fish got eaten the population changed and the population of fish decreased.
           The environmenmental impact of the fish pond is that these fish are being eaten! Now the fish population has decreased. This means that there would be less offsprings. Also, after the environmental disaster the green fish also got eaten. the algae and seaweed died. Because the fish food died there is a possibility that some of the other colored fish could have died from starvation. If some fish had offsprings the offsprings could have also died because they couldn't camouflage or from starvation. This was a huge environmental impact. If this project were changed my predection would be take all information independantly.Instead of losing the fish we could increase the amount of fish we have. This is how I think we could change the Toothpick Fish project.

New Planet in Universe, Similar to Earth

    There has always been talk about more plants in our universe, outside of the 9 common planets that we are aware of. However, up till now, none of these new planets have been of that much importance because they weren't made up of a solid base. Just recently, scientists discovered a planet called Kepler-10b which orbits the star Kepler 10. This planet, which is 565 light-years away, unlike other planets that have been found to be made of gas, is solid. It resembles earth more than any other planet. It is more than forty times the size of the earth and orbits so close to the star that it is extremely hot. I find this interesting because this is the first time that a planet was found that is solid and rocky, just like earth that we live on. This could mean that there may be other planets out there similar to this. It could also mean that there could be other life forms on this planet. Finding a planet like this is the first step in finding new life in the universe.
