what is the best way to make a strong structure with popsicle sticks, gumdrops and glue.?

When you put your parts together, make them in the shape of triangles. Triangles are the strongest shape for building a simple construction like the one you're making. Make your structure with many triangles. For example, if you can, make your entire structure in the shape of a triangle, and also connect the sides of the big triangle with lots of smaller ones.

if u want to make a good sciences project and u want it easy take a cup and add watter and then grab a piece of cardboard and and cover the glass and then turn the cup upside down and then the water wont fall ok

vinegar and baking soda. \nWill also be fun experiment for them!

With glue or sticky tape.

Here is the one I recently made:\n\nTake a transparency sheet and take ear buds (used for over head projectors)- lots of them. Dip the top of cotton part, of a bunch of ear buds, in glue and place them vertically on the transparent sheet. Go on doing this to make a square tightly filled with ear buds.  Note: you will have to give support to the ear buds until they are glued completely. \n\nNow you can apply the glue on the other side of ear buds and place another transparent sheet. Paint the central region of the ear bud-sticks with black colour. If required, cover the sides. It now looks like a square piece taken from a region in the plasma membrane.\n\nThe cotton ends now look like the hydrophobic layers on either end while the central region looks like the hydrophilic ends of phospholipids. If you want to elaborate, you can include proteins in the bilayer! You can use colour papers, ribbons etc (you can stiffen them by dipping in some glue and drying in the shape you want; I have also seen hair-bands available that form specific ion-channel like structures. Goodluck!

1. buy lots of popcicles.\n2. eat them.\n3. get elmer's glue (white)\n4. get busy.

You can look up the properties of Balsa wood.   I've done this kind of project many times.  The yeild strength of balsa wood depends GREATLY on the dimensions (length and width) of your piece.  The trick to making strong structures is to reduce any bending moments by supporting "flexible" pieces so that they are more rigid.\n\nThe strength of the glue that you use will also determine how strong your structure is.  Perhaps the best glue out there for Balsa wood is the Elmer's Wood Bond glue (Available at Home Depot).  I build furniture from time-to-time... and I'll vouche for this stuff.  Gorilla glue works well too. Superglues are faster, but are not nearly as water resistant (cyanoacrylate polymerizes in water and can create WEAK bonds).

Try to make it at 3 feet.  It will probably be easier.  I'd probably use balsa wood.

Thinking out of the box:\n\n  Just crumple it up into a paper ball.\n\nRough texture but easily a sphere.

fold it like an accordion, then add pieces to sandwich it (with glue) to make corrugated cardboard. Or make a lot of perpendicular pieces into a honeycomb and glue those into a sandwich.

you can cut strips of colored construction paper and form into loops, interlock the loops into a continuous chain, string popcorn, jelly beans, cereal loops, spice drops, the list is endess. I have even baked cookies (small ones) and put a hole in each and strung them up, looked really cute and my sons friends all got to eat them off the tree.

Sugar cubes and white glue work pretty well... you end up with a white Alamo though instead of a brown one...

There are various sites that explain how to build a paper blimp, just scale them up, as far as material goes you need an airtight flexible material that isnt subject to uv attack, mylar is the favorite.

method one - Hot Glue\nmethod two - Crazy Glue

Use toothpicks and colored gumdrops.\n\nChoose a color for: protons, neutrons, and electrons.\n\nThen use the colored gumdrops to represent them. for example, use 2 blue gumdrops for the protons, 2 red gumdrops for the electrons.\n\nthen connect them using the toothpicks- so end result is it looks lke an atom with te protons in the middle (nucleus) and electrons on the outside.

Use an ice cube. It will make the gum hard,  it should come off with a little work. Kinda like with wax. I hope it does.

Here's a site with alot of different ideas and difficulty levels with instructions.  Maybe you can find something here.\n\nOr you can tell us more about what you are wanting to do and what you like and we might be more helpful on here.\n\nhttp://www.all-science-fair-projects.com/
