Bee is a beautiful insect resulting from coevolution with flower plants. What can we learn observing a bee detail with microscope ? Work session objectives 1- Watch the video « A tour of a bee » 2- Fill in the gap in transcription text. 3- Choose a detail of a bee body you want to magnify with microscope using an external lamp. 4- Take a photo of the detail chosen and try to present it artistically. 5- Write a short text in English to explain what you're observing. Scientific report: 3 of you will be chosen randomly to prepare a short video report about bee with an ipad. This group will present his work to the others during the last 15' and will have to use props given by the teacher (a bee leg under microscope with flex cam, a comb, some mimosa flowers imitating pollen grains). No more than 1'30 for the video but no less than 1'. In a group, you have to cooperate (a cameraman and 2 reporters sharing time speaking). Organisation: in group of 3 / for 1h30 NB : don't forget to save your work on USB key in order to print it for the exhibition Resources: http://www.youtube.com/watch?v=fuj7w5u1N-M Gap-fill text vocabulary (at random of course!) pump

A tour of a bee Apis mellifera is one of the______ species that can be found in North America (..) Bees have certain things in common with other insects: – ______________________ which requires go through metamorphosis – a ______________body with ____ legs – 2 sensory ____________ Like their cousins wasps, they have 2 pairs of delicate _______________________. But unlike most of wasps, she's ________which makes it good for transfering pollen from one plant to another as the granules become tangled in those hairs. On both sides of her head, we can observe a ______________eyes with a bumpy surface. When we increase magnification, we can see hairs. Those sensitive receptors tell her about __________________, _________________... Each bump, called by scientists « ommatidium », is an independant image receiving facet better than our own for detecting ___________________. Comparing to us, she's myopic and receives fuzzy images (..) At the base of antennae are receptors. If we incompletely understand sensitive receptors, we think that they give the bee information about ________________ and _______________ (...) When she feeds on a flower, she closes her long open palps in order to form a ________ with her tongue to draw up the nectar from the flower. As she feeds, her body become coated with granules of pollen. These pollen grains are high _________ food which is the reason pollen is gathered for young and developing bees to build their body structures. Adult bees are carbohydrates (sugars) feeders (…) In rear leg, ______________ is visible. Pollen grains trapped between the hairs which form the basket contain the main genetic information of flowers that produced them. Along the leg, stiff hairs are lying in rows (…) At the end of her leg is a _________ which is used to pack a pollen basket. She comes with her right leg to pack the left and with her left leg to pack the right (…) She will use her _________ only for defending herself, for protecting her hive. Powered by muscle, she will drive the stinger with its __________ into intruder. Sharp barbs will hold it in place. Once used, she will _______(…) Delicate membranous wings give her the power of flight. Flat thin wings are strenghtened by veins and covered with short hairs. Our bee, young and fresh, have wings intact but during ________________, when she will be flying all day long, she will wear them out as pieces of these fragile structures break off (...)
