ACTIVITY Look for pictures of vegetables in magazines, books and the internet, or, if you have a camera, you can take pictures. Prepare a panel with figures and or photos and finds himself in some of them, there is the presence of the Fibonacci sequence. Suggest: cup pine, standing corn and sunflower blossom. What is perceived similarity between the sequence formed by the development of branches of Achillea ptarmica and the sequence formed by the reproduction of rabbits and development curves of the shell of Nautilus Marine Figure 6 - Plant Ananas comosus In the case of pineapple - Figure 6 - fruit originated in Central America and Mexico, rich in vitamin C and minerals like calcium, iron and phosphorus, the scientific name Ananas comosus belonging to the family Bromeliaceae, the adult plant consists of roots fascicular surface and a stalk (stem) in the form of short club. The leaves (bracts) long and hard-shaped troughs inserted in the stem, forming a dense spiral that extends from the base, form a rosette. Pineapple is a fruit compound, a result of the phenomenon of the inflorescence which arises 100-200 simple fruits ("buds"). Each "bud" recalls the approximate shape of a hexagon and participates in three spirals that intersect. The spirals forming an angle of inclination with the axis of pineapple, and according to that the angle formed with the shaft, the arrangements of the panels, visible in shell form a Fibonacci sequence. ACTIVITY As a group, bring to the classroom a few pineapples and look to verify the presence of the Fibonacci sequence in the arrangement of fruitlets ("buds"). What is the next number

AKTIVNOST Potražite slike povrća u časopisima, knjigama i na internetu, ili, ako imate kameru, možete fotografirati. Pripremite ploču s brojkama i ili fotografije, a nađe se u nekima od njih, tu je prisutnost na Fibonacci nizu. Predloži: šalica bor, stoji kukuruza i suncokreta u cvatu. Što je percipirana sličnost između slijed formirana razvoj grana Achillea ptarmica i slijedu formirana reprodukciji kunića i razvojne krivulje ljuske Nautilus Marine Slika 6 - Biljni Ananas comosus U slučaju ananasa - Slika 6 - plod nastao u Srednjoj Americi i Meksiku, bogate vitaminom C i mineralima kao što su kalcij, željezo i fosfor, znanstveno ime Ananas comosus pripada obitelji Bromeliaceae, odrasla biljka sastoji od korijena fascicular površine i stabljike (stabljike) u obliku kratke kluba. Listovi (bracts) dugo i teško obliku korita umetnute u kljun, stvaraju gustu spiralu koja se proteže od baze, formira rozete. Ananas je voće spoj, rezultat fenomena cvat koji nastaje 100-200 jednostavne voća ("pupoljci"). Svaki "Bud", prisjeća se približni oblik šesterokuta i sudjeluje u tri spirale koji se sijeku. U spirale čineći kut nagiba s osi ananasa, a prema onome kut koji tvore s osovinom, aranžmani od panela, vidljiv u obliku ljuske Fibonacci slijed. AKTIVNOST Kao grupa, donose u učionicu nekoliko ananasa i tražiti da provjerite prisutnost na Fibonacci nizu u rasporedu fruitlets ("pupoljci"). Koji je sljedeći broj
