SCIENCE LESSON PLAN: Forensic Science Ink Chromatography Overview : Solving a crime requires gathering evidence, technology, knowledge of the technology, experimenting, and an analysis of the results to draw a conclusion. Focus Questions: What do you want the students to learn from this lesson? Go back to the standards and GLEs to determine Focus Questions. a. What is ink chromatography, and why does it work? b. How can ink be characterized? c. What is solubility? This instrument serves as a scoring guide during the candidate’s participation in the activity “Learning About Energy”. The candidate must achieve a minimum rating of basic for each objective in order to earn a passing score. Rating Description Emerging Evidence is lacking or is inadequate for meeting the objective. Evidence presented by the candidate is below the minimum acceptable expectations of the program. Basic Minimum to intermediate performance is presented by the candidate in relation to essential knowledge, skills and/or dispositions required by the objective. Basic but substantially convincing evidence of attainment is presented that meets or moderately exceeds minimum expectations. Proficient Intermediate to advanced performance is provided by the candidate in relation to essential knowledge, skills, and/or dispositions required by the objective. Provides convincing evidence of attainment, usually with multiple examples of achievement that substantially exceed minimum expectations and show excellence in performance. Rubric Learning About An Unknown Animal Through Inquiry Objectives Emerging (0 – 1 point) Basic (2 points) Proficient (3 points) What is ink chromatography, and why does it work? Doesn’t know at all Understands the process of ink chromatography but not the science behind it Understands ink chromatography and can explain why it works How can ink be characterized? Doesn’t know, or just color Color and composition Color, composition, solubility, etc. What is solubility? Doesn’t know Understands that it has do with substances and their interaction with liquids Understands that it has do with substances and their interaction with liquids because of the chemical properties of both Goal: Students will get to use basic lab equipment to conduct an experiment and draw conclusions. “The assistant principal went to the teacher’s lounge during recess to make herself a cup of coffee.
