Lemonade Experiment Lab Report

In one of the experiments, the experimenter uses coke, lemonade, water, red party cups, and a thermometer. They put a measuring cup of each liquid into cups and they freeze them at 32 degrees Fahrenheit. The water froze the quickest, freezing within 2 hours. The Coke came second at 2 hours and 15 minutes. The lemonade froze the slowest at 2 hours and 35 minutes. The next site talks about how lakes, ponds, and puddles freeze in cold temperatures, but how the ocean doesn't. The reason for that is because of the ocean's high concentration of salt within its waters. Salt water freezes at a much lower temperature than fresh water. The ocean can freeze, but only at extremely cold areas like the North pole and the South Pole. It tells me that not

Their hypothesis is that if they put salt or sugar in water it will freeze faster than the plain cup of water. They held a vote to see which one is thought of to freeze faster. 3 voted for plain water, 4 voted for salt water, and 11 voted for sugar water. Their dependent variable was the element that changed from the sugar and salt, and their independent variable was the element that was changed by the sugar and salt. The materials they used were water, food coloring, sugar, salt, clear cups, and measuring cups.First, they collected the materials, then they poured water into each cup in even amounts, next they poured 1/8 of sugar in one, then they poured 1/8 of salt into another. They left one cup with just regular water and sat them in the freezer. They regularly checked to see which one froze the fastest. The sugar water ended up freezing first, before the plain and salt water. The plain water froze second, and in the last place was the salt water. By the end, the sugar water was fully frozen, the plain water was halfway frozen, and the salt water was 1/3 frozen. In the end the salt water was still partially a
