Faire des sciences avec Star Wars de Roland LEHOUCQ (numérique) De Roland LEHOUCQ Il y a bien longtemps dans une galaxie lointaine, très lointaine... le bon professeur Lehoucq contait déjà ses histoires ! Ce spécialiste ès bullshit dans les films de SF (et accessoirement astrophysicien au Commissariat à l'énergie atomique de Saclay et président des Utopiales, le festival international de science-fiction de Nantes) décortique chaque trimestre dans les colonnes de Bifrost les dernières productions d'Hollywood pour déméler le vrai du faux, le crédible de l'incongru, la science de la pseudo-science. Et lorsqu'il a fallu s'attaquer à Star Wars, il y avait de quoi faire un livre entier !
Paru pour la première fois aux éditions Le Pommier en 2005, Faire des sciences avec Star Wars revient dix ans plus tard dans une édition revue et augmentée, pour la première fois en numérique. De quoi patienter tout en se cultivant en attendant Le Réveil de la Force. Oh, et est-ce qu'on vous l'a dit ? Mots-clés : • Sciences • Star Wars (Au sujet de) Sommaire L'actu du livre. Sans titre. A mesure que les élèves grandissent leur possibilités sont décuplées…Et naturellement le programme en tient compte. 1- Lumière et Astronomie NOUVEAU : Réaliser une maquette permettant de mieux comprendre le phénomène des saisons C’est le domaine où la formation est la plus nécessaire : en effet contrairement à ce que l’on pourrait croire a priori, il est tout à fait possible d’enseigner l’astronomie en classe en rendant les élèves actifs et en étant assez peu dépendants des manuels scolaires.

CNDP. Sun Moon Scope. Engineering a Bridge. This lesson will involve your students in geometry and measurement as they work as civil engineers to design and build their own bridge. OBJECTIVE Students will be able to: Identify how geometry affects bridge design and function and apply that knowledge to the design and construction of a bridge.
MATERIALS Elmer's Foam board, Popsicle sticks, pipe cleaners, bendable rods, Elmer's Glue All, paper, pushpins, weightsEngineering a Bridge PDF SET UP AND PREPAREContent Introduction When engineers design a bridge, they must consider how the bridge will be used, how long and wide it should be, and how much weight it has to hold. Beam bridges are made of horizontal beams supported by piers at each end.Truss bridges are a combination of triangles made of steel. Essential Questions Use these essential questions to help guide students' thinking: How does geometry help engineers build bridges?
Craft Component: Bridge Engineering (20 minutes) Whiteboard Component Activities. Science Party: Bubble Slime. Here is Slime #2: Bubble Slime. A different recipe than the Regular Borax Slime, but this one again has just two ingredients: liquid starch (we bought ours at Walmart for about $2) and glue. Like regular slime, you can use either clear or white glue. This slime was a little more tricky to get right; you'd be able to blow a bubble regardless, but too much starch would make it too plasticky to support the bubble long enough to enjoy it and too much glue would make the slime too sticky and soft to handle.Here are our proportions:1/2 cup of clear glueAbout 2/3 cup of liquid starch (straight from the jug) Embellish the clear glue before adding any starch - we used glitter and food coloring and swirled it to make a lovely emulsion of pixie dust.
Start adding the liquid starch, bit by bit. Then it gets sticky and stretchy, and stretches indefinitely when you pull on it. which you can handle and squeeze and stretch slowly, but which breaks cleanly when you tug it quickly apart. Science Party: Fiber Optic Lamp. What's a Science Party without Physics, right? To balance out all those other Chemistry experiments, Emily and I decided it would be fun to do a little electric circuitry. We also wanted to stage a fake dissection as a token Biology offering, but fabric frog innards were too time-consuming to sew, so we filed away that idea into the Maybe Another Party category of my brain.
Before we settled on classic from-scratch circuitry, we considered the more trendy electric playthings now circulating the internet. Like electric playdough, for instance. Just for info, electric circuitry is not the same is electronics. I like both, but I like electric circuitry more because I can see what's happening in the circuit. Over the summer, Emily, with all that sunshiney time on her hands, started to dabble in electronics and simple computer programming. Fancy on the outside but, at heart, a simple, basic electric circuit with a battery, wires and a thing that lights up. 2 Light Device Ta-da! Observe: Bristlebot racing snail. Those mad hatters over at Evil Mad Scientist Labs have been at it again. After Windell wowed us with his simple but surprisingly motile “Bristlebot,” Lenore has taken it in a whole different direction with a snail plushie that moves by the directional motion of its velvet fibers.

The Evil Mad Science Auxiliary is a public group on Flickr for anyone to add photos that are (at least marginally) related to posts and projects from Evil Mad Scientist Laboratories. Lately some fantastic photos and projects have shown up in the group, so we thought that we should stop and round up a few– not all– of the great things that we’ve seen there. The photos below were taken by their respective owners; click on the individual photos to get the full story. A dark detector built by cyenobite, using a tiny battery holder.

L’humain à peau blanche a moins de 8000 ans ! - L'actu des juniors. Bristlebot: A tiny directional vibrobot.
The BristleBot is a simple and tiny robot with an agenda. The ingredients? One toothbrush, a battery, and a pager motor. The result? Serious fun. (YouTube video here.) The BristleBot is our take on the popular vibrobot, a simple category of robot that is controlled by a single vibrating (eccentric) motor. The starting point is of course the toothbrush. Cut off the handle of the toothbrush, leaving only a neat little robotics platform. Next, we need a vibrating pager motor or other tiny motor with an unbalanced output shaft. The kind that I got are happy to run on almost any common voltage– probably a range of 1-9 V. The last substantial ingredient is some foam tape. Attach the motor to the foam tape. A better method is to bend one of the leads down flush with the foam tape, so that you can *stick* the battery to the foam tape as well and still make an electrical connection.

That Thing There: Paper Circuit Projects from Maker Faire Detroit 2013. These are the "card" projects that I had at Maker Faire Detroit. I'm dividing the projects in two or three posts because I want to show the circuit paths both with and without notes and I didn't want the length of the post to get too unwieldy. Two quick notes: I took these pictures after Maker Faire and after they were abused examined many times over so they may look a little tired but that's because they are. However, this speaks to the hardiness of these structures. Also, all of these use Jie Qi's ingenious paper battery holder. The one shown above is the first card I experimented with. This is the circuit with my (hopefully) helpful notes of what's going on.
Ralph Robot There's a note on this one to look here for the reason for the longer piece of copper tape on the "switch". Santa's Treats I decided to play around with needing to press two "switches" to complete the circuit and light up the LED.

Le coin des enfants. Thunderbolt Kids. If we want to keep a record of how we constructed a specific electric circuit, we can take a photo of it. If we do not have a camera, we can remember the circuit by drawing a sketch. Look at the sketch below which Farrah drew of the circuit that you made in the activity with the paperclip switch. That's right Jojo. It takes time to draw a sketch like this one that Farrah drew. It will even take longer if we add more components to a circuit. And as Jojo pointed out, all of us do not draw equally well! The table shows the sketch Farrah drew and the symbol for each of the components of our circuit. REMEMBER: a battery is made up of chemical cells. When we put these symbols together to represent an electric circuit, we call it a circuit diagram.
Draw a circuit diagram of the sketch above. Compare your diagram with the one below. Take note that for electric circuit diagrams we represent the wires with straight lines. Let's now practise drawing circuit diagrams. Paper battery holder tutorial | The Fine Art of Electronics {under construction} This tutorial shows you how to make a paper battery holder for coin cell batteries (CR2032 and CR2016). Scroll to the bottom of this page for the video tutorial. Materials and Tools battery holder template printed on cardstock (download PDF here) conductive copper tape (available at digikey and sparkfun)regular tape (e.g. scotch tape or masking tape)scissorssurface mount LEDs (White, Green, Blue, Red, Yellow)3V coin cell battery (CR2032 or the thinner CR2016) Steps Step 1: cut out the template Step 2: cut two pieces of copper tape, about 3 inches long each Step 3: make the positive lead Take one of the copper tape pieces and peel off the paper backing.
Stick the copper tape over the horizontal part of the “L” shaped line, on the front of the battery holder, and fold the tape to follow the “L” shape. Leave the excess copper tape hanging off the battery holder. Folding to make the copper tape turn: At the turn, fold the tape back over itself so that the sticky side is up. This completes the turn. Kids science: Electricity 102. Science >> Physics for Kids Important things to know about electricity? Conductors and insulators - Conductors are materials that allow electricity to flow easily. Most types of metal are good conductors, which is why we use metal for electrical wire.
Copper is a good conductor and isn't too expensive, so it's used a lot for the wiring in homes today. Insulators are the opposite of conductors. An insulator is a material that doesn't carry electricity. Insulators are important because they can protect us from electricity. A battery can act as a source of electricity in circuits. Batteries use chemicals that react to make electricity. Alternate and Direct Current There are two main types of current used in electrical systems today: alternate current (AC) and direct current (DC). Static Electricity Sometimes electric charges can build up on the surface of objects. Take a quick 10 question quiz on electricity. More Electricity Subjects Science >> Physics for Kids.
