Fingerprints

This is the pie chart about the types of fingerprints in class.

From this pie chart I can conclude that the number of loops are the most common among the class, and the number of composites are the least common.

Skeleton Measurements

Simon's height: 157cm
Humerus --> 29cm
29*2.894+70.640=155cm(3sf)
Radius-->22cm
22*3.271+85.925=158cm(3sf)
Femur-->40cm
40*1.880+81.305=157cm(3sf)
Tibia-->35cm
35*2.376+78.663=162cm(3sf)
Average=158cm :DD
Near his actual height!!

My Height:169cm
Humerus-->30cm
30*2.894+70.640=157(3sf)
Radius-->26cm
26*3.271+85.925=171(3sf)
Femur-->50cm
50*1.880+81.305=175(3sf)
Tibia-->41cm
41*2.376+78.663=176(3sf)
Average=170cm(3sf)

Yay It is near my actual height :DD

There are discrepancies because our bones are unique and do not grow at the same speeds.

My body does not fit the golden ratio of 1.618... but it is around 1.60

This is my pic :DD

'Lefty' Lewis strikes again!

Part 3: Suggestions for the forensic scientist
-Look carefully around the crime scene, because there may be certain evidences that could point to the criminal cannot be seen without careful inspection of the place.
-Test the evidences as many times as possible to ensure that the results are accurate.
-Make sure that you identify the criminal as there may be 'evidence' that points the finger at others, or they will be mistaked for the criminals and be convicted!

'Lefty' Lewis strikes again!

Part 2: Evidence that may have been taken away by 'Lefty'is
-He had taken away the car, which showed that he was there, but there were tyre tracks for the police to find him!
-He took himself away, making sure that no one knew that he was the mastermind, but they still managed to find him! @.@

'Lefty' Lewis strikes again!

1. Evidence that may have been left at the scene of the crime
-Blood stains coming from when his hand was bleeding, it contained DNA that helped the police identify him.
-He did not wear his gloves, and since no two people have the same fingerprints, it is easy to identify him.
-He left his torch at the mansion.
-His car was leaking oil, which showed how he had came and went.
-Tyre tracks would be left in the ground and it could be checked against the tires of the car 'Lefty' Lewis had, and could confirm that he was there.
-Also, paint was left on the gate when the car clipped it. this could be matched to his car's paint.

Science experiments

As I was going through my Science practical file, I remember many of the interesting Science experiments that we have done. On of it was osmosis. Ms Leong had a Visking tube of water with starch. The water level continued to rise throughout the lesson and Ms Leong had to stop the experiment. Another one was the burning magnesium experiment. We held the magnesium strip over the Bunsen burner and it gave out a bright white light while burning. It was very fun :)

What is a black hole?

A black hole is a region in space where nothing can escape from it. Not even light is able to escape from it. A black hole has such a high mass that the gravitational energy generated is MASSIVE. Black holes are formed when heavy stars collapse in an event known as a supernova. There is a growing consensus that there is a black hole in the middle of most galaxies. There i evidence that there is a super massive black hole in the middle of the Milky Way. This black hole weighs 400 million solar masses, which is the weight of 400MILLION Suns! Because it is so heavy that not even light can escape, this makes it unable to be detected by telescopes. Instead, it can be seen by studying matter around it. However, black holes can evaporate and no longer attract all matter. They cannot attract everything forever. Smaller black holes take a longer time to evaporate and emit more radiation. I hope this has taught you more about black holes.

Global Warming and ways to prevent it :O

Global Warming is an effect which causes the temperature of the Earth to rise. This is because of excess carbon dioxide, which traps heat.
The way to solve it? Get rid of the carbon dioxide! Here are some ways to help lessen the amount of carbon dioxide you release:
1. Turn off the air-con, use a fan.
2. Grow plants :)
3. Try not to use repellents, these also contribute to global warming!
4. Do not smoke! Smoking produces lots of things that can also trap heat.( Second hand smoke is also bad for your health!)
5. Take public transport! Don't produce excess carbon monoxide by driving :)
We should try to save our Earth :D

Recent Science discoveries :)

Recently it was announced that a discovery had been made regarding an 'In-between' fish. It was named laccognathus embryi .It lived around 375 million years ago! It lived at a time where there was a transition of animals were in a transition from water to land. This makes me wonder about what life was like before humans existed, and this piece of news makes me want to know more about Earth and how life began and evolved. :D

Sabbaticals

Well, on week 9, me and Yi Chi went for the Aviation Science sabbatical workshop. We learnt many things about airplanes, and how the instruments in an aeroplane, such as the compass, works, using a gryoscope. They also taught us how to fly planes using flight
simulators in the computer labs. I had a very enjoyable time.

Results for Science at the end of Term 3

I got B3 for science this term... very disappointed. I think that if I had studied for this test I could have done better. I hope I can do better next term :D

Things I never knew :O

Recently Ms Leong was going through the digestive system. As she had not enough time to explain it fully, I went home and did some research about the digestive system! I found out many things I did not know, and many of the questions I had were solved, such as where the stomach acids went after digestion was complete. YAY :)

Science Problems

Today I went through my Science file again, preparing for EOYs... I found that there were many things that I had not gone through for a long time and i had forgotten :O
Gotta go revise for EOYs :D

LSS Lessons So Far

Well, so far it has been very enriching and in many aspects, it was new and provoked my curiosity to know more about the subject.However, there were times when it was quite hard and it was very difficult. fortunately with some revision, I could manage it.
Trying to do better for Term 4 Science exams :D
