Fragen:<br \/>\n<strong><\/p>\n<p>A- Entstehung eines geordneten Sonnensystems: Lasst eine Hand voll Murmeln im Uhrzeigersinn, eine mit weniger Kugeln gegen den Uhrzeigersinn um die Sonne laufen. Was passiert?     Klappt es jedes mal?<\/p>\n<p>B- Kannst Du eine gr\u00f6\u00dfere Murmel um die Sonne kreisen lassen, w\u00e4hrend eine kleinere Murmel als Mond um die andere Murmel rotiert?<\/p>\n<p>C- Wenn es zwei Sonnen gibt, k\u00f6nnen die Kugeln um Beide kreisen?<br \/>\nIst das schwierig zu schaffen?<\/p>\n<p>D- Laufen die Murmeln gleichm\u00e4\u00dfig schnell um die Sonne?<br \/>\nRolle eine Murmel dichter an der Sonne vorbei. Ver\u00e4ndert sich die Geschwindigkeit und die Form der Umlaufbahn?<\/p>\n<p>E- Wissenschaftler vermuten dass \u201edunkle Energie\u201c dazu f\u00fchrt, dass sich das Universum schneller ausdehnt. Was m\u00fcsste mit dem Stoff passieren, dass Objekte sich voneinander entfernen statt aufeinander zu fallen?<\/p>\n<p>F- Fallen Dir weitere Experimente ein, die man durchf\u00fchren kann? Probiere eigene Ideen aus.<\/p>\n<p>G- Warum werden die Kugeln langsamer? Warum werden Planeten nicht langsamer?<\/strong><\/p>\n<p>Das eigentliche Arbeitsblatt stelle ich online, wenn ich die Bilder gegen freie werke getauscht habe, oder durch eigene Zeichnungen ersetzen konnte&#8230; Und es etwas korrigiert habe. <\/p>\n<p>Noch ein Tipp zum Schluss: Der Transport gelingt am besten, wenn man kleine zusammengesteckte Clips dazu benutzt die Ringe zusmamen zu halten, und gro\u00dfe um die Standbeine zu B\u00fcndeln. Diese sollten drei links, drei Rechts verbunden werden, und dann f\u00e4delt man ein d\u00fcnnes 2 Meter Rohr durch und sichert dieses mit kleinen Clips an den Enden. So kann man das Unget\u00fcm angenehm tragen.

Does it work every time?<\/p>\n<p>B- Can a smaller marble orbit around a larger one like a moon, while both orbit the sun in the center?<\/p>\n<p>C- When there are two suns in the simulator, can you orbit a marble around both? Explain it&#8217;s orbit.<\/p>\n<p>D- Do the marbles orbit the sun at a constant speed?<br \/>\nShoot a marble close to the sun.<br \/>\nWhat do you notice about the speed and shape of it&#8217;s orbit?<\/p>\n<p>E- Scientists expect that &#8220;dark energy&#8221; leads to a faster expansion of the universe. How would you have to deform the fabric to make objects drift apart instead of Falling towards each other?<\/p>\n<p>F- Can you think of more experiments? Try different marbles, orbits and sun sizes.<\/p>\n<p>G- Why do the marbles slow down and fall into the center? Why does earth and the other planets keep orbiting for millions of years? <\/p>\n<p>It&#8217;s all a bit rough, and please excuse the rough translation.<br \/>\nI am not sure when I will be able to finish the worksheet, replace the images by ones with free licenses or self-drawn pictures and translate it to english.<\/p>\n<p>Some more advice:<br \/>\nFor transporting the simulator, use and connect smaller clips, attach them to hold the loops together.<br \/>\nAttach the legs to opposite sides and bundle them together with larger clips.<br \/>\nPush a small 2 meter pipe through the legs and secure it&#8217;s end with small clips. This way it can easily be carried around.<br \/>\nImages will follow.<\/p>","protected":false},"excerpt":{"rendered":"<a href=\"http:\/\/blog.pixelgiraffe.com\/?p=772\"><img width=\"150\" height=\"150\" src=\"http:\/\/blog.pixelgiraffe.com\/wp-content\/plugins\/thumbnail-for-excerpts\/tfe_no_thumb.png\" class=\"alignleft wp-post-image tfe\" alt=\"\" title=\"\" \/><\/a><p>deTrotz der geringen Gr\u00f6\u00dfe des &#8220;portablen Sonnensystems&#8221; funktionierte es ganz gut.
