	OBJETIVO	INTRODUCCIÓN	MATERIAL	DESARROLLO
SWIMMING FISH	UNDERSTAND THE SURFACE TENSION THAT HAPPENS IN THE MOLECULES INSIDE A LIQUID	ON THE SURFACE OF A LIQUID, THEY BIND STRONGLY THE LIQUID MOLECULES OVERHEAT. THIS CAUSES THE PHENOMENON KNOWN AS SURFACE TENSION THAT FORMS A TYPE OF SKIN IN WATER. SURFACE TENSION FORCES IF YOU PUT DROPS OF WATER ON A COIN OR METAL NEEDLE FOATING.	1-A LARGE RECTANGULAR MOLD 2. CARDBOARD PIECE 3. SCISSORS 4. DISHES LIQUID DETERGENT	1DRAW ON A CARDBOARD A SMALL FISH 5CM LONG 2-CUT A SMALL RECTANGULAR HOLE IN THE FISH TAIL 3-ADD A FEW CENTIMETERS OF WATER TO THE MOLD 4- IN ONE CORNER OF THE MOLD, PLACE ONE OR TWO FISH IN THE ROW ON WATER. IMMEDIATELY POUR A DROP OF LIQUID DETERGENT IN THE HOLE OF THE FISH TAIL. 5-ADD FRESH WATER TO THE MOLD TO REPEAT THE EXPERIMENT	-------------------- CONCLUSION THE FISH DOESN´T SINK BECAUSE THE WATER IS TOGETHER (SURFACE TENSION)

GETTING FINGERPRINTS 1ST GRADE 6.	STUDENTS WILL KNOW THE EPIDERMAL RELIEFS THAT ARE FOUND IN OUR FINGERS TIES THAT ARE ALSO A UNIQUE PHYSICAL CHARACTERISTIC THAT DISTINGUISHES EVERY PERSON BUT UNREPEATABLE	THE OUTER LAYER OF THE SKIN, IS CALLED EPIDERMIS AND A FINGER PRINT IS THE IMPRESSION LEFT BY THE ROUGHNESS OF HUMAN FINGERS. THIS ROUGHNESS HELP US FEEL THINGS AND GRASP THE OBJECTS BETTER. THE FINGERPRINTS ARE ESSENTIAL PIECES	MATERIAL 1-TWO WHITE SHEETS 2-TRANSPARENT ADHESIVE TAPE 3-PENCIL 4-MAGNIFYING GLASS 5-TRANSPARENT GLASS 6-COCOA POWDER 7- A BRUSH	1-ON A SHEET OF PAPER TRACE YOUR LEFT HAND WITH PENCIL 2-ON THE OTHER SHEET MAKE PENCIL STROKES ON THE PAPER UNTIL IT IS COVERED WITH GRAPHITE 3-HOOK THE ADHESIVE TAPE WITH THE FINGERPRINT ON THE LITTLE FINGER OF THE HAND YOU DREW BEFORE 4-REPEAT WITH EACH OF THE FINGERS 5-EXAMINE THE TRACES WITH A MAGNIFYING GLASS 6-RUB YOUR HANDS TO REMOVE THE FAT ON THE SKIN, THEN MAKE SEVERAL FINGERPRINTS ON A CLEAN GLASS 7-USING A BRUSH, LIGHTLY APPLY A LITTLE COCOA TO THE FOOTPRINTS OF THE GLASS 8-BLOW THE EXCESS OF COCOA POWDER AND EXTRACT THE PRINT WITH A PIECE OF ADHESIVE TAPE 9-HOOK UP THE PRINT ON A SHEET OF PAPER AND TRY TO COMPARE IT WITH THE SHEET WITH YOUR HAND SO YOU CAN IDENTIFY WHAT FINGER IS.	--------------------------------- CONCLUSION THE FINGERPRINTS ARE UNIQUE AND VERY IMPORTANT
