INQUIRY (Questions, Hypotheses): Students ask questions in a way that leads to a testable hypothesis.

EXPERIMENTATION (Experimental Design, Data Collection & Analysis): Students are able to design increasingly complex experiments. They are able to choose sophisticated tools for investigation and apply scientific knowledge and processes to real world situations. At this level, students still struggle with accepting data that go against prior assumptions.

EXPLANATION (Application, Explanation and Conclusions): Students are able to manipulate data to show trends and provide explanations. They are able to use statistics and probability and modeling in explaining results. They are able to find anomalous data, analyze accuracy of data and sample size, and improve experimental design. They are able to communicate the results of their own investigations in the light of broader scientific theories. Students understand the limits of scientific methods in terms of making broad conclusions. Students write formal reports using established conventions. Finally, students are able to integrate scientific knowledge with other fields of knowledge.
