Water

 OBJECTIVE: Observe the components of different tipes of water

MATERIAL:

• Different tipes of water, in this case two
• Forcceps
• "Plaquetes"
• Microscope

PROCEDURE

1. In different "plaquetes" put each tipe of water with the components
2. Put the "plaquetes" in the microscope and observe it

QUESTIONS:

1. What are the organisms that are in the water? Are microorganisms that live in the water.

Carrot and tomato

OBJECTIVE: To observe and indentify the different plasts of a carrot, a potato and a tomato

MATERIAL:

• Knife
• Scalpel
• Potato
• Tomato
• Carrot
• Microscope
• Plate
• Forceps
• Dropper
• 
  

PROCEDURE:

Carrot and tomato:

1. Cut a sheet of the carrot and the tomato with a scalpel or with a knife and put it in a plane and put one or two drops of distilled water in each sheet
2. Put the plate on the microscope and observe the plasts of the carrot and the tomato. You will see  the tomato´s chromoplasts and the carrot's chromoplasts

  

Potato:

1. Extract the juice of the potato with a knife or with a scalpel and put it in a plate
2. Then put two or three dops of lugol and remove surplus
3. Put the plate on the microscope and observe it. You will see the potato´s epidermis amiloplasts

                                       

PRBB ( Parc de Recerca Biomèdica de Barcelona)

Last week we went to the PRBB to do different experoments. In my case I do the electroforesy with the genes of a worms called C-elegance.

The electroforesy is used to know the large of this genes.

MATERIAL:

• Gloves
• Pipette
• 4 samples of different gens: daf-18 mutat, daf-18 silenciat, GFP+RFP -> fluorescència i Salvatge
• The electrophoresis

  
                          
PROCEDURE:

1. Put the genes with a pipette the different tipes of genes in a gel in a wells that are in the gel
2. Then cover the gel and electrify. 
3. These genes are going to move, ones more than others, depending of the largest of every tipe of genes.

  

RESULTS:

	MICROSCOPIA	IMATGE	GENÉTICA	COMPORTAMENT	RESULTATS
A	male: hermafrodita:	I: F	short	+sal -,-,+--> Si	DAF-18 mutat
B	male: hermafrodita:	I: F	large	+sal -,-,+-->  Si	GFP+RFP
C	male: hermafrodita:	I: F	large	+sal -,-,+-->  Si	SALVATGE
D	male: hermafrodita:	I: F	large	+,+,+,--> No	DAF-18 silenciat o apagat
