Knowledge and Skills Statement

Scientific and engineering practices. The student, for at least 40% of instructional time, asks questions, identifies problems, and plans and safely conducts classroom, laboratory, and field investigations to answer questions, explain phenomena, or design solutions using appropriate tools and models.

Engineering practices include using the engineering design process to solve problems. This design process is an instructional method that can be used to teach and apply various concepts in an integrated fashion. Students engage with integrated concepts from multiple disciplines and use design thinking to design a solution to an authentic problem. There are multiple model variations of the engineering design process; however, they all share the basic practices of asking questions or defining problems, brainstorming, planning, creating and testing a design, and improving the design. Throughout the process, students are engaged in problem-solving, teamwork, collaboration, and effective communication.

This process is non-linear and iterative. Flexibility within the engineering design process allows a student to return to a step if needed. Analysis and improvement often result in additional questions or problems that can be solved through additional design process iterations.

a type of investigation that involves comparing a process or behavior in two different settings

a type of investigation that involves simple observations to understand and explain a process or behavior

a type of investigation that involves a test with identified variables (independent, dependent, and controlled) to observe the relationship between the independent and dependent variables

detectable events that are observed through the senses or technology; can be explained through scientific laws, ideas, principles, and theories

Summary: "Science and Engineering for Grades 6-12: Investigation and Design at the Center" provides support for teachers and educational leaders in engaging middle and high school students in science and engineering.  Through an analysis of evidence and examples, teachers can support students as they make sense of phenomena, analyze data, construct explanations, design solutions, and communicate reasoning.
