The Scientific Method Portland Community College Staff* Version 42-0207-00-01 Lab RepoRt assistant This document is not meant to be a substitute for a formal laboratory report. The Lab Report Assistant is simply a summary of the experiment’s questions, diagrams if needed, and data tables that should be addressed in a formal lab report. The intent is to facilitate students’ writing of lab reports by providing this information in an editable file which can be sent to an instructor. obseRvations Data Table 1: Making Observations | Procedure†¦show more content†¦The pieces were clearer and sharper looking than the original rock salt. 2. Describe the initial observations made when several drops of water were added to few particles rock salt and the observations made several minutes later. Initially, the rock salt partially dissolved in the drops of water. After several minutes, the salt was more dissolved, but had not completely dissolved. There were very fine grains of salt that were visible at the base of the water bubble that hadn’t dissolved. 3. In light of these observations, what can be concluded about salt? Salt can be broken down and dissolved by water, but not in high concentrations. C. Do all the grains of sand look like they are made out of the same material? No. 1. Propose a hypothesis to explain the observed appearance of sand. Sand is a conglomeration of rocks and stones that have been broken down into sediments. 2. Describe what was initially observed when several drops of water were added to several grains of sand and the observations made several minutes later. Initially, when water was added to sand, the sand was unchanged. After several minutes, the sand continued to appear unchanged. 3. In light of these observations, what can be concluded about sand? Sand cannot be dissolved into water. D. The water and oil acted differently on the reaction surface. Propose a hypothesis that explains the different behavior ofShow MoreRelatedEssay scientific method1136 Words   |  5 Pagesï » ¿LAB 1 – THE SCIENTIFIC METHOD *Adapted from LabPaq CK-GCC Purpose: The purpose of this experiment is to learn about and use the Scientific Method.
