how do i make a volcano for my sons 5th grade science project?

Well first of all, why are you making it and not your son, after all it is HIS science project.\n\nTake a bottle, build a plaster of paris volcano mountain around it, put baking soda and red food dye into the bottle then just before the experiment is shown . add a teaspoon of vinegar - and watch the lava flow.\nBetter yet have your son do it under your supervision, he will learn more that way

There is a website on how to make a volcano model below

Vinegar reacts with the baking soda for the eruption to be effective. She's right.......use red food coloring. Did you already build the paper mache volcano? Have fun exploding!

I'm not sure about anything realistic or that they can learn from... but a fun activity, if that's all you want - it to get some old wire-mesh or anything else that'll make a good surface, shape it into an open-topped cone with something just inside the top of the cone that will hold a test-tube or small container just below the top of the peak (eg you could shape some wire to hold it, or perhaps tape or somehow else fix a tube in there). You can then build up your own volcano with papier mache, when it's dry paint it (eg white snow near the tip, dark green for trees lower down, or whatever you prefer). You then mix up some white vinegar with some red food colouring to represent lava, pour a little in the bottom of the container, and when you're ready, add a spoonful of baking soda or so to it! It fizzes up and runs down the sides of the volcano...\n\nThis is a pretty full-on project to make I suppose - you may just want to make one and allow the kids to play with it! It's not exactly realistic, but it's fun...

A volcano is made by a solid that turns into a liquid and has the opportunity to rise through some kind of solid. It helps realism if it includes something like gas, because that is also part of a volcanic eruption.\n\nThere are several great ideas here:http://volcano.und.edu/vwdocs/volc_models/explosive.html

The following really fun and interesting demonstration that is easy to set up:\n-This experiment should be performed outside as it creates quite a mess.  But it's worth it!\n-You will need  roll of Mentos brand mints, and a bottle of soda pop.\n-Roll a piece of paper into a tube, and put the Mentos in it (unless you have a flask/large test tube that the mints will fit in.  Trying to drop the mints in one by one will not work, the whole roll needs to go in nearly at once.\n-Open the soda bottle, line up your roll of paper with the mouth of the bottle, and drop in all of the mints.\n-You'll get a large eruption of soda!  I would suggest the person who drops the mints wear a poncho, or some type of protection against the fountain of soda that will ensue.\nThis website has an explanation of why the reaction occurs the way it does:\nhttp://www.stevespanglerscience.com/experiment/00000109\nIf you are going for something flashier (but much much more dangerous) my chemistry professor used to do the thermite reaction, that was always popular.\nHope this is helpful!  :-)

make a mini lava-lamp-like thingy.  get a cup, fill it about 3/4 full.  add food coloring, if u want.  pour a layer of oil about a centimeter thick.  then, pour salt, sugar, or sand, or all three on top of the oil.  it'll go up and down for a while, then the solid will settle at the bottom and the oil float stay on top.

Here is a site that has alot of science experiments that work well with the elementary age group.\n\nhttp://pbskids.org/zoom/activities/sci/

How to make a simple Van de Graaff Generator\n\nITEMS:\nPlastic Tupperware (microwave oven safe)\nSome wires\nNail\nSmall DC motor \nPiece of PVC pipe (approx. 3.8 cm in diameter)\nBroad rubber band \nWooden skewer\nPlastic bag\nRoll of tape\nSoft drink can\nMineral water bottle\n2 3volt batteries\nBattery holder (optional)\n\nPutting it together:\n1) Cut a hole in the middle of the bottom of the plastic container.\n2) Glue/tape the motor to the lid, making sure the shaft is at the centre of the lid.\n3) Using a hot nail (can be heated at the stove), make two holes near each other for the wires of the motor\n4) Thread the wires through the two holes (the two wires will connect to the batteries)\n5) Cover the container with the lid. (Inverted container in this case)\n6)Make another hole, perpendicular the motor shaft\n7) Thread another wire through(this will be your ground wire) \n8) Make the appropriate measurements for cutting your PVC pipe length and grooves(where the stick will rest)\n9) To make the roller, just stick tape to your stick and go round and round and round.\n10) Place the PCV tube on the lid, perpendicular to the motor. \n11) Thread the stick thru the rubber band and place it in the grooves.\n12) Make sure both rollers are parallel to each other when you thread the bottom of the band to the other "roller"\n13) Cut the top of the soft drink can.\n14) Cut both ends of the mineral water bottle off, making sure that it isn’t shorter than the PVC pipe.\n15) Make a hole near the top of the bottle.\n16) Strip some wire, twist it, and poke it through the hole.\n17) Electrically connect the copper wire to the soft drink can.\n18) Tape everything in place.\n\nWhen you put everything together, you get a crude Van de Graaff generator. Make sure the combs (end of wires) are near the belt and rollers. Make sure that when you run it, the belt doesn't slip off. If it does, make sure both rollers are parallel to each other. Also, try to superglue the motor to the Tupperware lid.\n\nWhen you first run it try taping strips of tissue paper to the can. It should start to rise seconds after the batteries are connected. If this fails, put your finger near one of the tissue strips. The strip should be attracted to your finger.\n\nPlaces with high humidity can be a real problem for electrostatic experiments. Try working in an air conditioned room to help overcome the problem.\n\nThe last two links are the best ones and both include detailed step by step process with pictures.

Hi!  This has been my fav. site when it came to doing science projects so far.  http://www.stevespanglerscience.com/index.php\nRemember to call your local papers and have a write up done on it so you have a good turn out for the crowd.  Good luck!

please do not do this for a science project.  too common.  but if you really want to know...most ppl get a small coke bottle and mould clay around it to get the mountain shape.

Use chicken wire to make a volcano like thing, then cover it with plaster. paint it and add trees and stuff like that. then mix vinegar, red dye and baking soda together to make the lava.

yes i won 1st place last week on how does density affect the movement of magma? i can give u the whole project nd what to do just email me my email is my display name at yahoo nd im in 8th grade nd they might even put my board in the metropalitan museum of art
