What do scientists and engineers do? Practices can be an effective starting point for implementation.
The Science and Engineering Practices (SEPs) of the Wisconsin Standards for Science provide a useful starting point to reflect on improving instruction. Students should be doing the work of scientists and engineers, not just learning about science and engineering. The practices are also not meant to be a new "scientific method" or to be done in order. As noted in this AIR report, scientific inquiry looks different in the WSS/NGSS, moving beyond simplified notions of a scientific method. The NRC Framework for K-12 Science provides an overview of these practices, as does this NSTA article by Rodger Bybee. The list of practices below links to further resources to build understanding and support implementation.
- Ask Questions
- Develop and Use Models
- Plan and Carry out Investigations
- Analyze and Interpret Data
- Use Mathematics and Computational Thinking
- Construct Explanations
- Engage in Argument from Evidence - including dialogue
- Obtain, Evaluate, and Communicate Information
- Define Problems and Design Solutions (Engineering)
Students should have opportunities to ask their own questions about phenomena and then design investigations and do research to begin to find the answers.

Like scientists, students should develop models that represent their thinking about a particular phenomenon. These models typically simplify (put boundaries around) a particular system to aid in making sense of it. The models could be mental models or might include drawings, diagrams, photos, graphical displays, formulas, computer simulations, etc. It's essential to note that models are not just recreated versions of provided information (like organelles of a cell), but a living tool for explaining, predicting, and comparing phenomena that is revised as new information is learned.

Starting in kindergarten students should have opportunities to carry out investigations. Their control over planning them will grow over time, perhaps beginning with choosing the variable to test in kindergarten. Cookbook labs should not be the norm; instead, students should be collaboratively determining what data and variables are important in understanding a phenomenon, how they'll collect relevant data, and whether their investigation will accurately provide the information they seek.

Across all subject areas, students should be using evidence to support their arguments. They need practice in figuring out how to design experiments and research to gather the data that they need and to analyze that data. It's important they also have opportunities to critique of the quality of that data and whether it's sufficient to answer the questions under study.

Students should not just be following a protocol or plugging numbers into formulas; they should be thinking mathematically, as laid out in the Standards for Mathematical Practice of the Common Core. Students should build up a conceptual understanding of how and why the math is used. One way that is sometimes done is for them to experience the phenomenon and model how that phenomenon works through mathematics - building up the necessary variables and relationships within those formulas. Computational thinking relates to mathematical thinking, requiring a logical sequence of steps to figure out and evaluate ideas.

What is good evidence? What is sufficient evidence? One structure for this practice is to have students support claims (answers to questions) with evidence, using scientific reasoning and understanding to detail why the evidence supports the claim. This CER approach (claim, evidence, reasoning) is applicable across subject areas and connect well to ELA standards.

Students should be talking about science - making sense of phenomena together. Based on research, teacher talk should be less than 30% of class time (even including whole-group conversations). In argumentation, students should be sharing their explanations and evidence, comparing ideas, and revising ideas through dialogue.

Students have access to lots of quality information and lots of misleading information. They need to be able to think scientifically as they obtain and evaluate this information overload. Engineers and scientists also repeatedly say that one of the most (if not the most) important skill in their work is effectively communicating.

Engineering and the impacts of technology on society are part of the science standards. They're intended to connect to and extend science learning, not be taught solely for the sake of engineering. Engineering questions will be part of the new Forward Exam in science, particularly with requiring students to consider criteria and constraints of designs.
