Arma Tu Modelo a Escala Del Telescopio Hubble

Hubble Space Telescope
Expert Model — Exterior
Directions
Materials:
• The patterns and instructions, which can be downloaded at www.hubblesite.org/go/model. The pattern pieces should be printed onto 32-lb paper. (You may want to have extra printouts handy in case you need them.) • Cardboard (the weight of a cereal box is good) • Glues: White or clear craft glue, gluestick (permanent), andsuperglue • Good scissors • A sharp craft knife with extra blades • A metal straightedge and/or ruler • A cutting board or similar surface Downloads, patterns, and other information at: www.hubblesite.org/go/model

Construction tips:
• Read through all the directions first and make sure you know where all of your materials are and what you will need to do. • Always follow safetyprecautions when using a sharp blade, like the one on a craft knife. • Have extra blades available and safely stored until you need them. Change the blade whenever it starts to become dull; a sharp blade cuts more easily and is safer to use. Dispose of used blades safely. • Don’t cut out pieces until you need them, so you can keep track of them. You can also lightly pencil the piece numbers on thebacks. Pieces are numbered and labeled in the recommended order of assembly. • Score fold lines before cutting out the pieces. This will make it much easier to fold the flaps later. Draw the edge of a narrow but not sharp object — like a butter knife or a small flathead screwdriver — along the dotted lines to make an indentation. Use a ruler to make sure your lines are straight. Alternately, youcan use the “dull” side of a craft knife, with a very light pressure so you don’t cut through the paper. Fold lines that are on cardboard require heavy scoring: use the point of the scissors or a craft knife to lightly cut along the line, just enough to make a small groove, but not going more than halfway through the cardboard. • Fold the pieces and try to fit them together at least once beforeapplying the glue. • Very small folds are easier to make with a pair of tweezers. • Keep your hands and your workplace clean and clear of scraps to prevent accidents and errors. • Protect your work surface with scrap paper, especially when gluing. • Keep your hands clean, so you won’t get glue or fingerprints on your model.

Optional (but very helpful)materials:
• Tweezers for handling small pieces • A small paintbrush for applying glue • Flat-edged toothpicks for applying glue and superglue • Thin dowels and/or tapestry needles to help roll up thin tubes • Clear spray-on sealant to protect the finished model

Before beginning construction:
1. Read all instructions carefully! 2. Have all of your materials ready. 3. Make sure a responsibleadult is nearby to help out if necessary. 4. Glue all the pages that require it onto cardboard and paper ahead of time, so they can dry. If they curl up when drying, press them under heavy books.

Construction tips continued:
• When using white glue, apply in a thin coat with a flat toothpick or a small paintbrush. If youwait a few seconds for it to become “tacky” it will stick more easily. • When using superglue, follow all the safety precautions on the label. Be VERY careful not to get any on your hands or skin, and do not touch pieces that have had superglue applied for several minutes, to be sure it is dry. • Only use as much glue as is needed to cover the surfaces you’re connecting with a thin layer.Too much glue may end up on your hands or on the surface of your model. • Be careful using sharp scissors and blades. Have a responsible adult nearby to help you if you need assistance. • When gluing two flat pieces of paper together, use as little glue as possible. The glue stick is very helpful for this. • Unless otherwise indicated, allow the glue to dry before going on to the next step....
