Objectives: Practice Writing Lab Reports Expectations/Notebook Set-up Conversion Review

Lab Report Must Include all elements outlined in the lab format. Turned in on time Conclusion must contain all elements

Lab Report Format I. Title of Experiment VI. Procedure ·Step by step II. Experimental Question The purpose of the experiment in the form of a question. III. Hypothesis IV. Introduction paragraph discussion outlining the important concepts in the experiment V. Materials A list of ALL of the materials used in the experiment VI. Procedure ·Step by step VII. Data & Observations VIII. Results/Calculations IX. Conclusion begin with purpose of the lab state hypothesis briefly discuss the procedure then discuss ALL of your data and results for the experiment finally conclude with whether you proved/disproved hypothesis why or why not

Lab Report Hydrogen Balloons How is Hydrogen produced? Hypothesis: Hydrogen is formed from a metal and hydrochloric acid reacting together. The purpose of the experiment is to observe, take data, and write a lab report concerning the production of hydrogen gas. Materials:

Materials: Zinc, HCl, beaker, test tube, balloon, weigh boat, lighter, stick, safety glasses, gloves, and string. Procedure: 1. Put on Safety Equipment 2. Obtained Materials 3. Put zinc in test tube 4. Put HCl in test tube 5. Put Balloon on Test Tube 6. Collected Gas and tied balloon with string. 7. Caused the collected gas to combust.

CLASS WORK Write the first five steps of your lab report in your notebook Data Table Observations Zinc Hydrochloric Before After

VIII Results and Calculations: The experiment produced hydrogen gas from a chemical reaction. There were several things that indicated a chemical change: change in temperature, color change, formation of a precipitate, and production of a gas.
