Lab - Heating Curves, Cooling Curves, Lauric Acid, Themochemistry, Latent heat
This lab will help your students examine the temperature changes undergone by a sample of matter during a phase change. Lauric acid is a great choice for this lab because of its relatively high melting point. Your students will also graph and analyze their data using Google Sheets or Excel (both versions of the lab are included). Setup is very easy with my materials sheet - see the product preview for details.
Learning objectives: Your students will be able to…
•Construct a heating and cooling curve for lauric acid.
•Analyze data obtained from the lab to determine if melting and freezing point occur at the same temperature.
Materials your students will need:
•2 - 400mL beakers
•Large test tube
•2 - thermometers
This lab activity includes:
•4-Page lab activity
•4 Post-lab questions
•Step-by-step procedures for the lab AND the procedure for making the graphs on Excel or Google Sheets
•Teacher’s prep guide
Perfect for technology integration and data analysis!
