![]() Previously, I have found that a parachute by the name of Tandem Icarus seemed to descend at the slowest rate. Repeat this step ten times a piece for each parachute. Take your first parachute drop it, and time it as it descends. Make sure the area at the bottom is flat. Find a high place off the ground like a stairway or ladder so you can drop the parachutes. Now do the same for the other parachutes. Then take 2 pennies and tape them to the tied ends. Now tape 4 strings to the four corners, then tie the ends together. Then I will cut 108 pieces of kite string that are going to be 40cm a piece. They will be wing-shaped and will be 39cm in width and 20cm in length. I plan to make three parachutes out of the 9 materials given to me. The purpose of this investigation is to determine, from the samples that were given to me by several companies, which parachute will descend at the slowest rate. The New Book of Knowledge.Grolier Incoparated. Which it causes the nails in saltwater to rust at a slower rate. Something faster than freshwater, but salt contains sodium chloride in In conslusion the nails inįrehwater rusted more than the nails in saltwater. My data alsoĬoncludes that the rusting color was black. Resolves that galvanized and common nails in freshwater had a higherĪverage or rust than the other nails in salt water. ![]() Steps for two types of nails in freshwater. Theamount of rust was recorded on both types of nails. The experiment was observed for two weeks. Nails.The nails were placed in glass jars and added with 150mL of water Quickly.The procedure involved sanding ten galvanized and common Of my experiment was to find out if salt water rusts nails faster thanįreshwater and which type of nails, galvanized or common will rust Title of my project is called On Your March, Get Set, Rust!
