i need to know how to draw the flitration process  also how to  write my obsevation oof seperating  salt and sand

i suppose the question i ask is have you actually ever done this?\n\nto seperate sand and water obviously you pour some water in a beaker with your sample and stir it, you filter the solution using a glass funnel and a filter paper.  you take the filter paper after you have finished and open it up and let it dry with the sand on, you take the water from the filtrate beaker and leave it to evaporate in a watchglass and then scrape the salt off.

It's gonna be water wait, no inches!!! exercise, watch the salt in take, exercise. Good luck.

I'll address this as a formal type of trial, kind of give you the extremes first, and you'll need to tone it down to the level that you're looking to do.  \n\nFirst, and I'd say most importantly, you need to do this to much more than one egg.  What your teachers will be looking for is a stistically signifigant amount.  If you do one, your answer is 100% one way or the other, which isn't too helpful.  \n\nSecond, I would do each egg in "regular" water first.  Since, when they were boiled, they were already exposed to that type of water, there isn't much chance of them being contaminated in any way.  I would then make a chart something like this\n\nEgg #   |  Floated in norm...  |  Floated in salt...  \n   \n     1                        no                       yes\n\netc.\n\nYou'll want to, in some way, be able to compare these, so that you can quantify your results.  For example  "85% of the eggs tested were more boyant in salt water than in normal water..."  \n\nWays to improve\nThe only big thing I can think of here, with out changing this to a general which liquid is most bouyant, is be consistant.  Check and make sure that the water levels are close, you don't want 6 inches of salt water and only 4 of normal.  Check the temperature of the water, if one is hotter it will help its bouyancy.  Make sure to use the same mixture of salt to water each time, if you use more than one container.  And consider using bottled water, probably not necessary at all, but tap water has a lot of other stuff in it.  \n\nMost importantly, write down everything you do.  Say you checked the water temp.  Tell them that the ratio of salt to water was the same every time (and what it was).  The more details you give them, the more through you show yourself to be.  Have fun, maybe you can make egg salad after you're done!

I would suggest start with the high level dfd (level 0) diagram where you have all your entities and just one large process in the middle. What you'll show in this level of dfd is all the inputs going into the system and and all the outputs generated by the system. From here you can determine what other processes you'll need. Also you have to do a functional decomposition diagram to determine what systems you need. \n\nI haven't used these for a while now but i hope this gives you some idea.

you can find a very good tutorial at the link.\n\nNo need to write whats already writtenm =)

Try using graph paper.  Draw a line segment from the origin to a point 3.5 units straight down.  Starting at the bottom of this segment draw a line that is 8.2 units that makes a 30 degree angle with the horizontal. \nThe third segment starts at the end of the second segment and goes 15 units to the left.  Connect the end of the third segment to the origin, this is the deplacement vector (make it red or something so you can really see it).  You can measure its length and the angle that it makes with the horizontal to describe it.

Make a Dodecahedron. That's what I did.

use water with salt spray.

ALWAYS draw a picture if you are having trouble.  Draw a vertical line - this is your tower.  Label it 60 (the height of the tower).  From the base of the tower, draw a line straight to the left.  This is the distance to the boat, so label it x.  Go ahead and close up the hypotenuse. Now you have a right triangle.\n\nThe angle of depression from the top of the tower = the angle of elevation of the boat = 3degrees.  This goes in the lower-lefthand corner of the triangle.  Now you have an angle, and you have values for the opposite side, and the adjacent side.  So which trig function uses opposite and adjacent?  Tangent.\n\ntan = opp/adj.\ntan(3) = 60/x\nxtan(3)=60\nx=60/tan(3) = approx 1144.87 feet\n\nThis site has some good illustrations for the chapter you are working on.  They may help you picture the problems better.\n\nhttp://regentsprep.org/regents/Math/rtritrig/LtrigW.htm

there are a few diff ways for this.  the way i do it is with a rotating lazer level. you can rent them at most rental places, another way is with a transit/builders level but if you dont know how...you will be lost cause you wont know how to read it. or the cheap and easy way.   get some clear plastic hose hold the ends up and fill it with water. create a "benchmark". use a post or somthing else you can tie it to and walk away without spilling. on the other end make a leg for you to rest it on roughley as high as the post. now as you move around you can see if it isflat by marking the level in the tube cause water will seek its own level. i prob left out some things in the explanition but im sure you will pick it up.....it was good enough for the romans and it can work for you.

The way I do it is through paint shop pro, or photo adobe then use animation shop, you can find a lot of great online tutorials using google

YOUR LEGS SHOULD STAY TOGETHER AND MOVE IN THE MOTION OF A DOLPHIN. ARMS START OUT IN THE FRONT OF YOU TOGETHER PUSH DOWN WITH HANDS AS YOU ARE MAKING A YOUR ARMS BUTTERFLIED OUT OF WATER OVER HEAD AND PUSH WATER DOWN HEAD COMES EVER OTHER STROKE FOR BREATHE BODY SHOULD HAVE SMOOTH MOVE EVERYTHING WORKS TOGETHER VERY HARD TO DESCRIBE IN WORDS EASIER TO SHOW

test the reactions of different substances in water. like um put in sugar and salt and then say it dissolved. And put in oil and say it freakin stayed seperate or whatever it does

I dont have code but a quick search might net you some...\n\nIf i was going to do it myself however... my first thought would be to start with highest level items and list across the page at the top\n\n[A]   [B]   [C]\n\nThen check each item for children and draw links (using any drawing tools you like)\n\n[A]   [B]   [C]\n  |   /\n[D]\n\nand follow down.. depends really on your data... how much/linking type etc:\n\nGet all items with no relationship\nList across the top layer\nGet all items related to [A]\nList across second layer, draw links to [A]\nGet all items related to [B]\nList across second layer after, draw links to [B]\netc etc, then 3rd layer\n\nobviously youd use a loop however

Tear a piece of paper up into ten pieces.  Write down an option on each and then fold them up.  Now, mix them up a bit and then draw one out.  Do whatever option you draw.  Have Fun!!!
