Scientific and Engineering Practices are integrated throughout the entire semester through hands-on activites, labs and assessments.
4
Scientific and Engineering PracticesBegin each lesson by posing a clear, open-ended question or problem that encourages students to identify independent and dependent variables and develop hypotheses.

Design activities that involve hands-on investigations where students plan, measure, and control variables, using appropriate tools and technologies for data collection.

Include tasks for students to organize and analyze data through graphs and comparisons, promoting interpretation and evaluation of patterns and findings.

Encourage students to construct explanations and claims based on their data, compare multiple solutions, and reflect on the reliability and validity of their conclusions.

Integrate opportunities for students to create and use models or simulations to represent concepts, and to gather, assess, and communicate scientific information from diverse sources both in writing and orally.
