Emerging Science Process Skills: Those skills which we expect students to be developmentally prepared to practice at this level.

INQUIRY (Questions, Hypotheses): Students are able to make predictions and develop multiple hypotheses based on their own observations.

EXPERIMENTATION (Experimental Design, Data Collection & Analysis): Students are increasingly able to conduct their own investigations. They can identify and control variables, choose appropriate tools and methods and conduct investigations of increasing duration.

EXPLANATION (Application, Explanation and Conclusions): Students can identify trends in experimental data and represent them in a variety of graphical formats. They can recognize the relationship between explanation and evidence. They are able to identify sources of error in 'fair-test' experimental results. Students at this level rely on formal knowledge, techniques and conventions as they write formal reports and use quantitative data.
