en SCIENCES? - La classe de Mme Barry
en SCIENCES? Bonjour!! Our next unit in science will be on Simple Machines as part of the Structures and Mechanisms strand. We will be learning more about how movement is a change in the position of an object and how simple machines such as: levers, inclined planes, pulleys, wheels and axles, screws and wedges, help make our lives easier because they help us move objects. We will be learning about different kinds of simple machines, investigating how they work and where they can be found all around us. We introduced the unit with the Scientists in the School program in April. It was amazing! The students loved learning about science through hands-on activities and real life simple machines. All students were engaged and excited! During this unit we will be investigating the following big ideas about movement: Ø Movement is a change in position of an object. Ø Simple machines help objects to move. Ø Mechanisms are made up of one or more simple machines. Ø Simple machines and mechanisms make life easier and/or more enjoyable for humans. What activities could you do at home to support your child? ü Show/ discuss with your child how simple machines are part of our/their everyday lives (teeter-totters, bicycles, toys, cars, elevators, ramps, staircases, scissors, etc.), ü Review the definitions page attached to discuss the purposes of each type of simple machine. ü Go for a walk in the neighbourhood and make a list of all of the simple machines you see. Categorize them into their appropriate type of simple machines. ü Visit the following websites: Canadian Science Museum – kids zone • http://www.sciencetech.technomuses.ca/english/schoolzone/machines5.cfm Simple Machines and Forces – The compound machine • http://www.edheads.org/activities/odd_machine/ ü One of the important expectations of the Ontario Science and Technology Curriculum at all levels is for students to “use appropriate vocabulary in describing their investigations, explorations and observations”. Please encourage your child to use the words on the following page when communicating her/her knowledge of simple machines with you. Here is a list of vocabulary we will be using throughout the unit that you can practice with your child: « les mouvements » - different movements: s’entourer – to turn around something pousser - push rouler – roll tirer - pull pivoter – pivot voler - fly tourner ou tournoyer – turn équilibre ou balance- balance rebondir – bounce glisser - slide sauter – jump soulever – lift ferme – close ouvrir - open, les mouvements linière (linear movements) = horizontale, verticale, en pente (slope) « les directions des mouvement » - different directions that objects can move in: s’approcher – coming closer or approaching avancer – advancing s’éloigner – going further away reculer – backing up sous – under devant – in front of monter – going up descendre – going down sur - on dans - in derrière - behind à coté de - beside « Les machines simples et leurs parties » - simple machines and their parts : rampe – ramp levier – lever roues – wheel axes – axle coins – a wedge poulies – pulley point d’appui – pressure point extrémité – an end plan incliné – inclined plane lisse - smooth rugueuse ou bosselée – rough or bumpy distance parcourue – the distance the object moved friction - friction charge – a weight une vis – a screw Have fun making science part of our everyday lives!
