Student Guide Laboratory: Drop and Bounce Different matter responds differently to force. In this lab‚ you will explore the relationship between matter and energy by dropping objects made of different materials from different heights to see how high they bounce. You will be dropping these objects in a virtual lab setting where objects behave the same as they would in the real world. Goals for the Lesson Solve a problem using the scientific method. Use the metric system in a scientific experiment

Mariana Mendoza Alvaro Puccini Maria Quin Solubility Lab Purpose: The main purpose of doing this lab is to learn how to interpret solubility graphs and how the temperature does affects the solubility of different substances. There are other objectives of the lab which are learning what are concentrated‚ diluted‚ supersaturated‚ and saturated substances and how can they be identified. The hypothesis of this lab would be that when temperature increases‚ the amount of salt and copper

Introduction: The importance of this lab is to get a deeper understanding of how the concepts of solutions and insolubility applies to the lab’s purpose of making chalk using precipitation reactions. A precipitation reaction is when a solid/ precipitate (insoluble) is formed when two solutions that contain soluble salts are combined. Some additional scientific concepts investigated in this lab are insolubility‚ double replacement‚ and limiting reactants. Insolubility occurs when a solute is incapable

PR OCEDURE Before beginning‚ set up a data table similar to the Data Table: Experiment Results in the Lab Report Assistant section. This experiment will create a reaction of sodium carbonate and calcium chloride dihydrate to produce a precipitate of calcium carbonate. This formula is: Na2CO3(aq) + CaCl2. 2H2O(aq) à CaCO3(s) + 2NaCl(aq) + 2H2O 1. Put on your goggles. 2. Weigh out 1.0 g of CaCl2·2H2O and put it into the 100-mL beaker. Add 25 mL of distilled water and stir to form the calcium

In this TLC lab‚ we explored the relative polarities of Acetylsalicylic Acid‚ Ibuprofen‚ Acetaminophen‚ and Caffeine based on their functional groups. The most overall polar analgesic is considered to be the analgesic that contained the most polar function groups. The amine and amide functional groups are the most polar. In this experiment‚ we found that both these functional groups are found in Caffeine. As a result‚ Caffeine was the most polar out of Acetylsalicylic Acid‚ Ibuprofen‚ Acetaminophen
