Name_____________________________________ Science 8 – Science/Math Lab Report Guidelines: Comparing Molecular and Ionic Compounds LAB – ON PAGE 169 IN YOUR TEXT! Title Page – follow usual guidelines (left margin, separate page!) Purpose – Your purpose should reflect the task to create a bar graph from a data table in order to compare and contrast the melting and boiling points of molecular and ionic compounds. Methods – Explain in a numbered list what you did to complete the assignment. Data – Include your bar graph here on a separate sheet of graph paper. You are constructing the graph yourself, not from Excel. Be sure it is labeled and colored with a key. Analysis – Answer questions # 2-5 on page 169 in complete sentences, thoroughly and accurately, in a numbered list. Conclusion - Your conclusion should be an essay about: What you learned about the melting and boiling points of ionic and molecular compounds - how do they contrast? Explain chemically what causes these differences. Design an experiment to compare the melting and boiling points of ionic and molecular compounds. References – You should have two references written in PROPER format (use www.easybib.com, MLA format) Grading based on the following rubric: BE SURE to compare your lab report to the rubric below – you should score yourself a 100 before you hand it in to me!! Title Page – 5 points Purpose – 15 points (Did you explain the goal of this lab activity?) Methods – 10 points Data – 15 points (Is your table on graph paper, labeled, titled, accurate, correct x and y axes?) Analysis – 20 points (5 points each question) Conclusion – 20 points (Did you address the three topics listed above?) References - 15 points ( 5 pts/reference + 5 pts. for format) TOTAL = 100 points = test grade
