i need ideas on how to build a lighthouse for my 4th grade daughters project?

There are actually places where you can buy kits for model lighthouses.  Just do a search for "building a model lighthouse".\n\nYou could use pieces of styrofoam insulation - easy to work with, inexpensive, light weight.  In hobby shops you can probably buy thin pieces of balsa which would also be easy and light and easier to paint than the styrofoam, and would be my first choice I think. Check hobby shops for kits too.  YOu will probably opt not to use a kit, but they could give you ideas.\n\nThere is the question of whether you want the light to be real or pretend, moving or not moving.  I'd use a Christmas tree light I think, but there are lots of LCD lights available now at Walmat - check in the campoing section usually - you might find something there that will work better.  \n\nFor display purposes you probably want the lighthouse to stand on something that looks like a rocky seashore - papier mache works well and then paint it - recipes available on line.  Papier mache keeps hte project relatively light and easy to move around.\n\nIf the lighthouse is to have windows at lower levels as many lighthouses do, aluminum foil works well.\n\nI hope these thoughts are of some help.  Good luck to you and your daughter.

umm just make them perpendicular to the sun.  wait till like 1 pm and put a pencil standing up on your panels and adjust the panel until there is no shadow. it is then perpendicular

atach a wire to each part of the batter, attach them to the light. create a circuit and you will have light

Buy a large glass vase from Wal-mart (I picked one up this weekend for $1.97), a strand of 20 count lights ($.97 at Wal-Mart), and a bag of potpourrie ($1.00- I did a christmas scent, but this "craft" can be used year round, so maybe a scent/color combo that works well in thier homes?).\n\nPut the end few lights in the vase, add some potpourrie, add more lights, add more potpourrie, etc, etc, but leave the end of the cord out. I had some ribbon in my fabric bin that I used to tie a bow around the neck, and secure the cord down on the glass. When it's plugged in, as long as you have a vase with a large mouth and only slightly narrower neck (avoid the type that cinch in tight), enough air circulates that these light up air freshners are perfectly safe to use. The lights warm the potpourrie to give off scent, while looking pretty. They look nice in baskets, too.

4th grade, what a wonderful year. Here are some ideas they'll love.\n\n1. Make reindeer mix with oatmeal and sprkinles. Tell them  to sprikle it on their lawn on Christmas Eve.\n2. Have them spread icing and add sprikles to a sugar cookie.\n3. Make presents for loved ones such as wrapping hot cocoa mix packages.\n\nHope this helps!

Try a party store. Look for table skirt clips. They should be able to attach to the awning and then you clip the lights on.............

go to a craft store (or even a department store with a craft department such as walmart) and buy dowel rods, small styrofoam balls, and craft paint - you can paint everything the color you need it to be (remember to get a top coat for the paint!) and put it together using the styrofoam balls to join the dowel rods

Cut the top off of a milk carton. Glue a popsicle stick to the side of the plastic that reaches well above the carton, glue another stick perpendicular to the first to make an L shape. Add a fabric or other material sail. It will float!

use a real tree\nbut make sure leaves must not be withered\nan wrap with ligth bulbs..\nand use cotton wools as snow

You're talking about a Class 4 laser.  \n\nThis is more than you can do in a science project.  A laser like that would have high voltage and the light could easily blind you, and the components would be more expensive than you think.  The assembly and alignment is a very fussy procedure, and can't be done in a home workshop, due to the dust that's everywhere.  \n\nMaybe you could make a twyman-green interferometer, for measuring curvature of glass, but it won't be very dramatic.\n\nI figure that a motivated adult with some electronic and physics background, $50K, and a lot of time on his hands might be able to do it in a year.\n\nIf you're into optics, you can do some demonstrations with the beams from laser pointers....

Carefully chose what you want to use to keep the lights up.  Using cup hooks works well.  Screws also stay in for a long time.  Once you place all your hooks/nails/screws about every 3 feet, they should last for years.  This will make light hanging go quicker for the next several years.\n\nAlso, try not to let the lights drop onto the driveway or sidewalk.  Be sure the lights are all working BEFORE you put them up.  Nothing is worse than getting them all up, plugging them in, and finding out they don't work!\n\nBut, worse then finding out they don't work, is putting them up and then discovering that you put the wrong end by the outlet!

Lots of candles always look nice. You could make some candle centerpeices for each table, put a few flowers and braches around each one, keep it simple. And fairy lights are always good too. I saw one where they put the icicle lights underneath the white table cloth of the head table and it was really soft and pretty

Place a reddish orange candle in a Hurricane vase and place the vase in the center of an autumn leaf wreath.  Use a round mirror on the bottom which will reflect the candlelight. \n\nFor Hurricane vases check out this site:\nhttp://www.save-on-crafts.com/hurricane.html

The best way to learn is by doing, And it is a difficult concept to understand that light can be broken.\n\nI would reccommend that you use prisms to break up the light into spectrums. you can use chandelier crystals or something like that.\n\nThen you can have them put the light back together: Heres how: get three slide projectors, and get some colored acetate in cyan (turquoise). magenta, and yellow to place in front of the projection lenses OR Better Yet take slides of peices of paper that are these colors and place one in each of the slide projectors. If you angle the projectors so that the projections overlap, it should form white light.

The following link has some good ideas for different projects.  \nhttp://www.all-science-fair-projects.com/category0.html\n\nAlso, the following link might help you set up a science fair display board if you have to have one.\nhttp://www.sciencebuddies.org/mentoring/project_display_board.shtml\n\nAn easy, but unique, project for a science fair entry is to test different types of materials for fire resistance.  My daughter used wool, cotton, satin, silk, rayon, nylon, and polyester.  All that is really needed for the experiment is the different materials and a candle with a small flame.  Make sure that you make your science board really neat and legible and clearly state your hypothesis and your observations.  Then, write a conclusion about what you learned from your experiment and whether or not your experiment proved your hypothesis.  Good luck!

If you are making a model this might be useful for you:\nUse cardboard to create a ocean with ups and downs. Cover it with dark blue oil paint and some white color for the foam. You can use transparent plastic sheets to cover this model to get a glossy effect. Try not to put the sheet very tight. Stick it loosly so that it creates an effect like waves.\n\nIf you want to make the whole classroom ocean-like, then make it slightly dark and run a cassette with the sound of the waves.
