Hi\nYou can just use a simple plastic water,drink or juice bottle.\n\nIMPORTANT NOTE:your rocket may not work if you use a screw lid.\n\nTo make rocket:\n1 Tape a straw to the side of the bottle:make sure that one end of the straw is within 1-2cm of the top of your bottle\n\nTo make launch pad:\n1 Insert skewer into a round piece of cardboard so that the skewer is standing securely upright.\n\nTo launch rocket:\n1 Insert one of the following fuels:\n   1x crushed alka-selzer tablet and 15ml of water \n   1 teaspoon of baking soda and 40mL of vinegar.\n2 Then put on the lid on as soon as the substance(s) are in the rocket.\n3 Place rocket on launch pad so that the skewer goes through the straw.\n4 watch in amazement as your rocket takes off!

ok--i'm not completely sure about this--but i can at least try-- *cough cough*unlike some people*cough*cough*catweazle*\n\nwe did this type of stuff last year.  but i think that you might want to use the ideal gas law?? we always called it pervnert... PV=nRT... does this sound familiar?    \n\nif not, i suggest asking your teacher, or some other knowledgable chemistry person.\n\ni hope this helps!

Here is a nice experiment to try.\nhttp://www.angelfire.com/mo/sasschool/DKScieMatter10.html\n\n"This tasty crystal making experiment is a great way to see the formation of crystals almost right in front of your eyes."\n\nAnother one.\nhttp://homeschooling.gomilpitas.com/explore/crystals.htm\n\n"Crystal Ornament"\n\nAnother.\nhttp://www.yesmag.bc.ca/projects/crystal_gardens.html\n\n"Crystal Gardens"\n\nOne for microscopic crystals.\nhttp://www.science.uwaterloo.ca/earth/waton/crystal.html\n\n"Crystal growing made easy"

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!

just make it out of clay or soap. You can carve it out of soap with a knife.

some good projects for kids are at-http://pbskids.org/zoom/activities/sci/\nthese might be too easy for anyone older than a 3rd grader, but they're still something!\n my little brother is doing the water filter.  he's going to see which of the materials filters water best. good luck! :)

Since this is a school project, your teacher probably wants to you to learn more than just how to build one.  \n\nLearn to use the library.  Learn to use internet search engines.  Learn to spell what you want to build.  Learn to be self reliant.

How about a caterpillar? Check the crafts dept. at Wal-mart. Use stryo balls for the body, just glue five or six together in a line,  which you'll need to paint of course, add pipe cleaners for legs, just use wire cutters to cut them in thirds and just stick them in and bend them down, then use the stick-on googley eyes that they sell, and add a colored piece of paper cut for the mouth, and two toothpicks painted black and stuck in his head for antenna. Easy, and uses 5 materials

I did something similar to this when I was in 3rd grade or so. What I did was take cheese cloth (can be bought at walmart in craft section and many craft stores) and wrap it around the head while wet with a flour and water paste. Just secure the bottom with a rubber band, the cheese cloth will create a canvis like surface on which you can use paint or markers. After that I got my brother to spray paint the bottle white and when the heas was dry I hot glued it onto the neck of the bottle letting the end of the fabric hang down inside. For clothes I used felt you can buy at craft shops that is already sticky on the back, but for yours I'd say you could just use markers on the spray painted parts because he wouldnt have really had cloth clothes if he's in a space suit. \n\nI'd sugest drawing a square on the head as a face window and drawing the face inside that. You could also go to the hardware store and get some small riged tubes usually used to secure wire to go from the back of the head to the bottom of the "suit" of the spaceman. \n\nIt would be neat to make space boots out of the bottom of two smaller water bottles glued onto the bottom of the larger bottle and painted white with the rest of the bottle. Good luck!

I have made 2 liter bottle rockets using water, a tubeless tire valve, a bicycle pump and a 2 liter bottle.  It goes about 100 feet up if you do it right.

do a erupting volcano. \nAll you need is viniger and baking soda.  Red food coloring on viniger if you want it to be red lava.

Try eduplace.com or edhelper.com\nCrayola.com is also free and has great ideas.\nThe public library has LOTS of books for crafts and BillNye type experiments.  The books by VANCLEAVE are excellent and easy to follow and implement.\nBelieve it or not, google exactly what you want, you'll find lesson plans too!
