The mixed tomato liquid is in the funnel with the filter. The filtered liquid drops into the test tube.

dna extraction
 

Materials:

- tomatoes
- knife
- baker
- petri dish
- blender
- funnel
- NaCl (sodium)
- detergent
- dest. water
- isopropanol
- wodden Stick
- test tube

Accomplishment

- Just take the tomatoe and cut it into piecies, which have to be     about 1cm³
- After this we put them in a petri dish and add 2g of Salt (Sodium chloride) and 5ml detergent
- We smash the mix as much as possible
- Then put it into the baker
- Take the blender and mix it for 15 seconds
- Pour the tomatoe extract through a filter into the test tube
- Put 20ml of it into another baker
- Add 20ml of ethanol
- Wait some minutes until you can see some thin threads in it
- You can grab them with a stick to see them better!

Analysation

We made some things wrong. These are the things we should pay attention to next time:

     - We di not mix long enough
     - We should use more detergent

Isopropanol does not solve the DNA and so it is very useful tho extract the DNA. The DNA forms bullets that rise up to the top of the liquid.

Question: What happens if we pour liquid sulfur into the water?

Material:

  • Powder of Sulfur   
  • A glass beaker filled with water     
  • Bunsen Burner    
  • A test tube     
  • A few matches

Sulphur-Powder-Granulars8bunsenpic

Accomplishment:

  • Put the Sulfur powder into the test tube 
  • Heat with the bunsen burner (activated before whith a match) until it becomes liquid
  • Pour it into the glass beaker

Observations:

  • The sulfur liquid becomes brown after a while
  • If you don't wait long enough (until it's brown), the experiment fails
  • The liquids move very slowly, which requires a lot of patience
  • If you fail the first time, you have to pay attention, because the surface of the water mix might have become solid, so change the water
  • The sulfur becomes similar to a gum

Evaluation:

If you heat Sulfur till boiling point and you quench it immediately with water, it forms a transparent, sticky and elastic substance, which is called amorphous or plastic sulfur.

Hey, this is the group working on new frontiers.

Do you know Einstein? Of course you do!!=)

Well he was a great scientist and found the equation (e=mc²), which showed how a small piece of mass could produce an unbelievable amount of energy. In his theory of relativity Einstein then demonstrated that not even time, mass or length are constant.

Now something about his life. He was born in Germany and lived in Switzerland for a long time. Later he moved to the USA. There he advised President Roosevelt to develop the atomic bomb. At the age of 76 he died in New Jersey.

He was also famous for being eccentric. For example, he never wore socks, he talked to his cat and couldn´t remember people´s birthdays. Also he found it difficult to write in English.

Coming soon your group: New Frontiers =)=)=)=) <3
