Summary of the Project
Students will perform a titration using acetylsalicylic acid and sodium hydroxide to determine the amount of acid found in different brands/types of aspirin. Students will complete pre-lab questions, perform the lab, and answer conclusions questions. Using Smore, the online poster builder, students will communicate their results and reflect on their lab. The lab will consist of one class period of pre-lab activities, two class periods of data collection, and one final class period to design the online poster.
Begin
Read the lab in its entirety and complete the pre-lab questions.
Perform
Perform the lab completing as many trial in three class periods as your group can. Wear all of your safety equipment the entire time.
Final
Create an online poster using Smore.
Lab Materials
1 Buret, 2 beakers, 2 graduated cylinders, 1 mortar and pestle, 1 balance, 1 lab pro, 1 pH sensor, 0.1 NaOH, Bayer, generic aspirin, low dose aspirin, ethyl alcohol, and distilled water.
Materials for Project
Titration Lab Packet, Assessment Rubric, Logger Pro Software, and online poster builder, (www.smore.com)
Learning Outcomes
Students will create a visual to communicate the results of their titration lab using an online poster.
Students will explore the differences, if any, between different brands of aspirin.
Students will perform a titration to determine the amount of acetylsalicylic acid found in various aspirin.
Students will name sources of error after performing the lab.
Requirements for Project
Using the online poster builder, found at www.smore.com, you and your group members will be making a poster to communicate your results to your classmates as well as the teacher. See the assessment plan above for a specific rubric.
- Group member names must be on the poster.
- Title of the lab is clearly displayed.
- Purpose of the lab is written clearly.
- Overview of the lab is written clearly and pictures provide additional support.
- Pictures of actual group members performing the lab with all goggles and aprons on are visible and of good quality.
- Results of the lab are clearly and concisely explained.
- At least three sources of error are listed.
Grouping of Students
Students will be predetermined by the teacher and grouped based upon their abilities and personalities. For example, natural leaders and students with higher level thinking abilities will be together and students who are more shy with the laboratory equipment, but very creative will be together. Grouping by abilities ensures collaboration and that no one person dominates or completes all of the work. In addition, when grouping students by abilities and personalities often increases motivation, determination, and comfort by students.
