Did you ever want to get a tattoo but your parents don't let you? Well I promise you that when this tattoo comes out on market they will 'beg' you  (this is not a promise...) to 'wear it'. This will be a teeth tattoo but not an actual shape like hearts or names etc. but something that will prevent you to get sick! Isn't that amazing? Mike McAlphine- University Assistant  Professor- says that it can sensor the harmful bacterias and informs your doctor with a wireless system. In order to create the 'sensor' they used Graphene, which is really sticky and sensitive, peptides, that attracts the bacteria, and the glue type of thing that they bacterias get stuck on. You will tell me now that " I am afraid to go at the dentist.." well I also don't like pain but I would definitely put it because it is painful.. There is just one more small detail that we have to consider! Scientists have to actually make it smaller in order to fit in human teeth... but it has been tested at COWS!!! This would be really useful for soldiers in battles so they don't get a diseases that can be harmful but deadly. I hope that we will have it soon in market and can use it because it is really useful but Mike still needs some commercializing...

Australian Spiders Weave A Wickedly Cool Web

Australian Spiders Weave A Wickedly Cool Web

By Meera Dolasia on 03/08/2012

I am pretty sure that everybody that is reading this current event dislike spider and especially their webs. We all remember Charlotte the spider from the movie. Well believe it or not, she is the only spider that I like (just because she is a movie). Well for the first time spiders in Australia really impress me so read the article!

 On the 5th of March, more than 8,000 people that lived in the New South Wales were asked to leave their houses because of the flood, caused by the overflowing of the Murrumbidgee River. The following day they were allowed to return to their houses and instead of the green grass in the land near their houses they saw something white and (un)fortunately it was not snow. IAccording to the author “It was the magical work of thousands of tiny Linyphiidaespiders that reside in the are.” you would ask, ‘why did they do that’. As the people tried to escape from the flood, so did the spiders, and they build this giant web using a ‘trick’ that it is called ballooning and helps them float up in the air with the  help of the wind! Because there were only a few dry spots, for not to submerge, they linked the trees (or hight lands) with the web in the grass. These kind of spiders are not really common and know because they are tiny and usually build their web near the ground and they are called the money spiders because people think that they bring luck! it is not the first time this wonderful and amazing thing happens but it also happened in Pakistan in 2011! In Pakistan the webs were really useful because they trapped the dangerous diseases and were transferred from the mosquitoes.

Video Of The Week - Apollo 17 Astronauts Frolic On The Moon!

by: Meera Dolasia on 02/27/2012

           One of the biggest events in the history was when NASA landed a spacecraft on the moon for the first time!  As everyone knows, the spacecraft was named Apollo 11 and it was landed on June 20, 1969. The three astronauts, Neil Armstrong, Buzz Aldrin and Michael Collins were the first one to fly there and were very excited because it is really cool and awesome to factually land and step on the moon! the real Moon. Everyone would be excited if we was about to lad on the moon, so they were and  Neil Armstrong for to show his excitement or to stay in history, he said “This is one small step for a man, a giant leap for mankind” according to the Article. But on December 7, 1972 another spacecraft landed on the moon with two astronauts as a crew named Harrison Schmitt and Eugene Cernan. Those two men did something really funny and something that only kids would do (but they were really excited); they were jumping up and down singing a son named ‘I was strolling on the moon one day”. !!

          I chose this article because landing on the Moon was one of the most important events that happened in history and none would expect the second landing like that. But if I were on the Moon I would also be very excited and do something silly. This video is interesting and I think it could attract anyone’s interest and since we are on the astronomy unit and we are doing about the phases of the moon I found it suitable for my current event.

The moon phases

Yesterday in class we did a lab where we observed the moon phases.
Observations:

ANALYZE AND CONCLUDE:

1. In your model, what represents the Earths? The sun? The moon? A big foam ball represented Earth, a smaller one the moon and the sun was a flashlight.
2. Refer back to your eight circles. How much lighted part of the ball did you see when facing the lamp? As in the moon phase one, from Earth you can’t see anything because the sun is behind it but as in number three you can see the whole moon (the part that s facing Earth).
3. Label your drawings with the names of the phases of the moon. Which drawing represents a full moon? A new moon? Which represents the waxing crescent? The waning crescent? Number one represents a new moon since you can’t see anything because the sun is behind the moon. The fool moon is the figure five were you can see the whole moon since the sun is in front of the moon. The waxing crescent is number two and the waning crescent represents number eight.
4. How much lighted part of the ball did you see after each turn? If you observe the phases of the moon from space (the top of your experiment) you would see both side and each of them would be brightened or lightened, depended on in which phase it was. When you look at it from Earth you can see only one side of the moon and sometimes it is full dark or bright (new or fool moon) and sometimes you could see half of it (first and last/third quarter) and at last from some point you could see one third of it (waxing, waning crescent, waxing and waning gibbous).
5. Wether you could  see it or not, how much of the ball’s surface was always lit by the lamp Was the darkness of the new moon caused by an eclipse? Explain your answer. Always half of the moon was lightened but we couldn’t see it always (depending on the side you are, the angle you see it from). The lightened part of the moon was facing the sun so we couldn’t see it so the new moon is not caused by an eclipse.
6. Write a brief analysis of this lab. How well did making a model help you understand the phases of the moon? What are some disadvantages of using models? What is another way to make a model to represent various phases of the moon? Creating a lab was really important for me because I understood the phases of the moon, got to see the from different angles and how it looks from the front and the back but also see it from the space view and earth view. A disadvantage of making a model is that it is not really accurate but it help and another way of making a lab is using our heads and a bigger flashlight so we can observe it better.

Reasons For the Seasons

 Reasons For the Seasons Lab

 
 


Guiding Question:  How does the tilt of the Earth's axis affect the light received by the Earth as it revolves around the sun?
Hypothesis: The tilt of the  Earth's axis affects the light received by the Earth as it revolves around the sun because the light goes at the equator and there is not that much light at the poles and at the other side of the Earth there is no sun at all (it is night)
 
Lab Observations

Winter:

·         More squares at the equator (below it).

·         Most light near the equator.

·         More rectangular/stretched out at the poles.

·         Not much shadow in the Northern Hemisphere.

Summer:

·         No light in the Southern Hemisphere.

·         Most light near the equator.

·         Very long shadow.

·         No shadow at night.

·         Longer shadow in the morning and evening.

·         Less shadow during midday.

 


Questions from Lab

ANALYZE AND CONCLUDE

1. Observing   When it is winter in the Northern Hemisphere, which areas on  Earth get most concentrated light? Which areas get the most concentrated light when it is summer in the Northern Hemisphere? When there is winter in the Norther Hemisphere the areas below the equator get the most concentrated light and when it is summer in the Norther Hemisphere, the areas below the equator get the most concentrated light.
2. Observing  Compare your observations of how the light hits the area half way between the equator and the North Pole during winter and during summer. When it is summer, there is no light in the Southern Hemisphere and the most light it is near the equator and it has a very long shadow. There is longer shadow in the morning and evening and less shadow during midday. When it is winter, the most loght is again near the equator but there is not much shadow at the Norther Hemisphere 
3. Inferring If the squares projected on the ball from the acetate became larger, what can you infer about the amount of heat distributed in each square?  If the squares were becoming larger there would be less heat in that area because it would be near the poles (as we observed)
4. Inferring According to your observations, which areas on Earth are consistently coolest? Which areas are consistently warmest?Why?The warmer areas on Earth are the ones that are near the equator and the coolest ones are the ones that are near the poles (because they don't get so much light and the areas near the equator are always warm because the sunlight it is always coming directly near the equator)
5. Predicting What time of year will the toothpick shadow we longest? when will the shadow be shortest? The longer shadow there will be in the summer and the shortest will be in the winter
6. Drawing conclusions How are the amounts of heat and light received in a square related to the angle of the sun's rays? When the sun is indirect there is less heat and it spreads. When the heat spreads that means that there is less heat so the squares ill receive less heat and sunlight.
7. Communicating Use your observations of an Earth sun model to write an explanation of what causes seasons Seasons are caused by the Earth's rotation around its axis!
   

There's a New Planet in Sight

There's a New Planet in Sight
by Catherine Clarke Fox
  Astronomers recently discovered a new planet, larger that Jupiter that orbits  a star 500 light years from Earth. It's so obvious that astronomers don't even need a super telescope and even beginners can see it with a normal telescope. The planet it's called TrES-2 because according to the article, " it is the second such planet found by scientists working on the Trans-Atlantic Exoplanet Survey (TrES)". The transiting planet is easy to observe and answer question about them but only if you know math and relationships to its star!? This planet is made up by gas and it is so hot that there is no possibility for life because there is 1,500 Celsius. Scientist may send an instrument on a mission to space and the new found planet will help them to see if their instruments work because they already know so much about the planet.
      I chose this article because in science we are at the astronomy unit so I found it interesting because it is not usual to discover new planets. The thing that grabbed my attention is that it is really, really hot there and they are truly no possibilities for life there! I learned that there was another planet that was found before some years and that transiting planets are easy to observe. The site that has this article is really reliable and I know it is true. It was really interesting reading this article and learning so many things about this planet. This is affecting scientific knowledge because there might be life there and it will be really awesome if there is actually.

'Mini(Mize)' Your Paper Usage With This Mini Printer

'Mini(Mize)' Your Paper Usage With This Mini Printer
by Meera Dolasia

Are you always feeling guilty when you print a lot of stuff and you waist so much paper or when you print a sentence in a huge paper sheet? Well the London-based design firm, Ben, found the solution to your feeling! A mini printer. But what is so amazing about that? The answer is easy. The only thing you have to do is connect the mini printer to a internet connection and download the application on your mobile phone. Then, when you go to page or when you receive an e-mail or a message the only thing you have to press is send, in the top of your screen (that it will always be there) and then the mini printer will print it. You can also connect it with anything else you want but you need to have the application. You can also send messages to other mini printers. The good thing about this new printer is that it doesn't use as much paper, it doesn't use ink (the heat that it takes it turns it into ink) and you now don;t have any more any excuses when you miss birthdays or events! This smart printer will come out approximately in 2012 but they don't know yet the price that you will have to pay to buy it.
I chose this article because recycling is a big global problem those days and we really don't have trees, money and paper to waste. The thing that grabbed my attention and that I liked most is that it doesn't  use ink (this is a really smart way not to waste also ink). I learned that heat can turn into ink and I was pretty much impressed. It was really interesting reading this article and watching the video because it is so good for the environment and I have never thought that someone can invent something like this.
