Science Task Prescreen
Task Title: Ideal Gas Law Derivation (Scaffolded): Step-by-Step from Boyle and Charles to PV=nRT
Grade: High School
Date: 2024-06-01
SEP: Analyzing and Interpreting Data
DCI: PS3.A (Definitions of Energy)
CCC: Patterns
Task Purpose: Provide a scaffolded inquiry where students follow structured steps to analyze pressure-volume-temperature data from gas simulations, discover Boyle’s Law and Charles’ Law with explicit guidance, combine them into the Ideal Gas Law, and apply it to predict gas behavior, aligned to HS-PS3-2. This version provides additional supports for struggling learners.
Instructions
- Before you begin: Complete the task as a student would. Then, consider any support materials provided to teachers or students, such as contextual information about the task and answer keys/rubrics.
- Prescreen: Answer the following high-level questions to identify any major red flags (🚩) in your task. If you find one or more red flags, consider the purpose of the task and the evidence gathered to determine whether the task warrants a deeper dive.
Prescreen Questionnaire
| Question | Yes | No |
|---|---|---|
| 1. Is there a phenomenon or problem driving the task? | [x] | [ ] 🚩 |
| 2. Can the majority of the task be answered without using information provided by the task scenario? | [ ] 🚩 | [x] |
| 3. Can significant portions of the task be answered successfully by using rote knowledge (e.g., definitions, prescriptive or memorized procedure)? | [ ] 🚩 | [x] |
| 4. Does the majority of the task require students to use reasoning to successfully complete the task? | [x] | [ ] 🚩 |
| 5. Does the task require students to use some understanding of disciplinary core ideas to successfully complete the task? | [x] | [ ] 🚩 |
| 6. Do students have to use at least one science and engineering practice to successfully complete the task? | [x] | [ ] 🚩 |
| 7. Are the dimensions assessed separately in the majority of the task? | [ ] 🚩 | [x] |
| 8. Is the task coherent and comprehensible from the student perspective? | [x] | [ ] 🚩 |
Recommendation
Based on your assessment needs and the task purpose recorded above, make a recommendation about this task moving forward (choose one):
- [x] Warrants further review.
- [ ] Should not be used.
Summary
Summarize your evidence and reasoning:
This scaffolded version of the Ideal Gas Law Derivation task guides students step-by-step through the analysis of gas behavior, deriving Boyle’s and Charles’ Laws before combining them into the Ideal Gas Law. The scaffolding (explicit prompts, partially completed data tables, sentence starters) increases accessibility for struggling learners while maintaining three-dimensional integration. Students analyze and interpret data (SEP) to identify patterns (CCC) connecting particle-level energy (DCI PS3.A) to macroscopic gas relationships.
