Chemistry and the Titanic

Some metals and metal alloys undergo a transition to brittleness at cold temperature. This phenomenon likely contributed to the demise of the Titanic.

Science Coaches and Classroom Mentors

Teaming up with a STEM Science Coach or mentor can be rewarding to both you and your students. I was surprised at the impact a science mentor has on students when I recieved an email from a former student.
First Day Chemistry Engineering Activity
Melissa Hemling | Sat, 09/07/2019 - 22:26
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!

Synergistic Inquiry

Some research indicates that it is not always beneficial for students to work entirely on their own as they conduct inquiry-based investigations. This article explores a method of inquiry learning in which teachers and students work together to envision, conduct, and analyze experiments.
Break the Ice with Mystery Blocks

In an effort to align my lessons with the Next Generation Science Standards (NGSS), I have tried to take the content I have traditionally taught, and shift the design to focus on student engagement with the science and engineering practices outlined in the standards. For the topic of heat transfer I re-packaged the ice melting blocks discrepant event as a NGSS investigative phenomena.
