Law of Conservation of Matter Lab Problem: How can we prove that matter is conserved in a chemical reaction? The purpose of this lab is to investigate the law of conservation of matter. You will need to design an experiment in which you demonstrate that matter is not created nor destroyed in a chemical reaction. You will then follow the steps of the scientific method and write a lab report with your findings. To help guide you through the steps of the Scientific Method, complete the sections below. You can various household substances to create a chemical reaction. Some ideas that you can use to create an experiment around include the following: Alka-Seltzer Tab in Water Mixing Vinegar & Baking Soda 1. Develop a Hypothesis related to how you can show the law of conservation of matter in a chemical reaction. A hypothesis is an educated guess as to the outcome of the experiment. Based on prior knowledge or research conducted, what do you think will happen in your experiment? Make a prediction on how you will be able to show matter has not been created nor destroyed in the chemical reaction given the materials you are using. Hypothesis: 2. Test the Hypothesis by developing a controlled experiment. At this point you need to determine what additional materials you will need as well as the steps needed to conduct this experiment. To help you plan, you need to write out the specific steps needed to carry out your experiment. You must design an experiment that has quantifiable results. In other words, you must design an experiment in which you will be making measurements in order to clearly accept or refute your hypothesis. Your experiment should also include repetition of measurements. You should repeat the procedures a couple of times to make sure you are getting similar results before making a conclusion. Materials Needed: Steps of Procedure: 1. 2. 3. 4. 3. Design a data table in which you will collect your data. Be sure to collect quantitative data as well as qualitative data. Draw a Data Table: Include any pictures or drawings of your results: 4. Write a conclusion paragraph. In the paragraph state whether your data supports or refutes your hypothesis. Discuss any modifications you would do if you conducted this experiment again. Discuss how accurate and precise your measurements were and if there was anything that could be done different to improve. Talk about what you have learned by conducting this experiment. Conclusion Paragraph:
