Current Events: Ancient Flower Blooms Again

30,000 years ago, an Arctic squirrel decided to bury seeds and fruits in an underground chamber in northeastern Siberia. The ground became permafrost, which is a layer of soil that stays frozen for a long time. Recently, Russian scientists dug out those pieces of fruit. With those pieces, the scientists managed to grow plants in the lab! These plant deserves to go in the Guinness World Records because they are the oldest flowering plants that researchers have ever revived from a deep freeze. This article was released on March 16, 2012.

       The discovery that plants can be brought back to life from 30,000 years ago is amazing! Just think about what this could mean for the science world! In the future, some plants that are common today may be non-existent, such as daisies. So we could bury the plants for later use. Also, if that plant could cure some disease that we didn't know that it could, people from the future would probably be able to revive that plant and use it. Imagine the lives that plant could save! I hope that we continue discover more ancient plants, revive them, and use them to cure ourselves from sickness. It may eventually lead to preserving human life as well... who knows.

States of Matter: Lab Report

   For the past week, my science class has been doing a series of labs. They were all focused on demonstrating chemical and physical changes . For the first lab, we used a skinny green candle and a stout white candle. The green candle was textured, smooth and had a spiral on it the white candle was just smooth.   There was no chemical changes present at this time.When our teacher lit the green candle, it started melting (a physical change).  It started getting shorter and smaller. There was smoke and  the candle was burning (both chemical changes).
   In the second lab we did, it also involved a candle. We mixed vinegar and baking soda together, which created the gas carbon dioxide, Then we poured the gas over the flame that our teacher lit on the candle. The fire did not immediately go out because my group mate did not tilt  the glass containing the carbon dioxide enough. But eventually, the flame went out because there wasn't enough oxygen.
   The third lab that we did was with marshmallows. We used a small marshmallow, a large marshmallow, a stick and a bunsen burner. We ripped the small marshmallow in half and tasted it. It tasted sweet and soft. Then we burnt the large marshmallow with the stick and the bunsen burner. Then we had to taste the burnt part. It tasted horrible, burnt and crispy. One person in my group said that it tasted good!
   The fourth and final lab was also very "sweet". We dissolved sugar and the person in my lab that tasted it said that it was like Chinese Tea. Then we put sugar in a test tube and placed the test tube over the bunsen burner using tongs. The substance inside the test tube turned black and yellow smoke came out from the test tube. All in all, last week was extremely fun.

Lab Procedure

Lab Procedure

1.Firstly, pour the water from the plastic cup into the flask using a funnel an a spoon.
2.Remove the toothpicks from the plastic cup with your hands and set them on the filter.
3.Remove the white beans from the plastic cup with the scooper and place them on the filter.
4. Pour water from flask into graduated beaker and place on hot plate. Plug in hot plate.
5. Remove excess water from plastic sup with pipette and place in graduated beaker.
Pick up Marble from the plastic cup with your hands. Place on filter.
6. Remove the iron fillings from the cup with a magnet and place the magnet on a filter.
Item remaining in cup should be sand.
7. Remove the hot plate pug  and CAREFULLY put the beaker on the tray using tongs.
8.Wash scooper.
9.Place the substance that is inside flask onto the filter using the scooper.
10. Identify the substance as salt.
11.Finally, count all the items you have seen in the cup. You should have toothpicks, white beans, a marble, iron fillings, water, salt and sand.
