I have to build a model ship with only aluminum foil, toothpicks, and hot glueIt was to be able to carry 1.000kg of sand in a ziplock bag and still be able to float on fresh waterThe idea is to get it to stay afloat and have little mass as possible.I know I should start with Archimedes Principle with buoancy force and all thatI get that the buoyant force has to be equal to the force of gravityI'm stuck on figuring out what the weight/mass should be of the ship for it stay floatingHelp please?
Valence electrons are the electrons on the outside of the atom diagram the react the most with the surrounding atomsthey are on the furthest level.
On the top of the periodic table there are usually numbers like 1A, 2A, 3A, 4A, or some say 1, 2, 13, 14etcthose are the valence electronsThey are how many electrons are in the outer shellExcept do not inclube the B group.
The boat needs to displace a litle over 1 liter of water so use a 2 liter soft drink bottle for a mold and make your boat bigger than half Build a frame out of toothpicks and glue the same size and shape as the 2 liter bottle laying on it's side just a little longer to have the extra needed volume Mold the foil around the frame and glue the foil to the frame Check it to be sure it does not leak
