Science Practice: Analyzing and Interpreting Data

NGSS during e-Learning Part 1

With the end of school upon us and the possibility of remote instruction in the fall, here are some techniques  to address four NGSS science and engineering practices; Planning and Carrying out Investigations, Asking Questions and Defining Problems, Developing and Using Models, Analyzing and Interpreting Data.


Making a (big) eruption with chemistry!

As teachers, we can leverage fruitful discussions about chemical control with students to elicit more about students' initial ideas and ways of reasoning. From asking students to clarify their own thinking, we can identify students’ own productive ideas that we can capitalize on to advance their thinking.

Limiting Reagents and Gases

This unique microscale gas collection technique provides students with reasonably good data in a short period of time. Students have more time to analyze the data and communicate their findings. 

Chemical Kinetics with a Smartphone

This experiment in chemical kinetics can be conducted using materials as simple as a smartphone, hydrogen peroxide, sodium carbonate solution, and blue food dye! The experiment is useful when discussing the order of rate laws with respect to reactants.

Measurement, Uncertainty, and Significant Figures 

As high school teachers, we know that understanding how measurement works is crucial for lab skills and for understanding significant figures. We think measurement should be an easy topic for students to learn; especially because we know that teachers begin working with students in elementary school to teach these skills. However, I, and many other teachers, have spent countless hours teaching and reteaching a seemingly simple skill.

First Day Chemistry Engineering Activity

I just finished my first week of school, like many teachers in the Midwest. I work hard to get my Honors Chemistry students in a lab setting as soon as possible. It is difficult to find a perfect lab to do on the first or second day of school. In my mind, the ideal first chemistry lab would require no prior chemistry knowledge, involve interesting chemistry, address an NGSS standard, be relatively safe, not require expensive glassware or lab tools, and reinforce positive class norms. I have found engineering labs fit the bill! I don't know if I have found the "perfect" lab, but I have found something close I want to share!

Gas Laws and Deflategate

If you are looking for ideas to create an authentic opportunity for students to apply their knowledge of gas laws while integrating some of the most important science practices, then this activity may fit your needs.
