Summary
In this lesson, students will evaluate their puffy-paint Sharklet surface models they made in Lesson 3. Students will use sticky notes and binder clips to simulate the accumulation of bacteria on both the Sharklet surface and a flat surface. As students compare their three models, they will collect data to compare with the rest of the class in Lesson 5.

Learning Goals/Student Objectives
- Test multiple Sharklet-inspired surface models and evaluate their effectiveness.
- Compare predictions with experimental results.
- Analyze data collected from controlled tests of model prototypes.
- Draw conclusions about how surface structure influences performance.
- Create and interpret tables and graphs to represent experimental data.

Safety Precautions, Hazards, and Risk Assessment
-Binder clips should be handled carefully to avoid pinching fingers
-Sticky notes and tape present minimal classroom risk
-Standard classroom supervision required
-Overall risk level: Low
NGSS Standards, if applicable
3–5-ETS1-1: Define a simple design problem reflecting a need or a want that includes specified criteria for success and constraints on materials, time, or cost.

3–5-ETS1-3: Plan and carry out fair tests in which variables are controlled and failure points are considered to identify aspects of a model or prototype that can be improved.
