How many of you could recite, word for word, a definition you learned in school? When you first memorized the definition, you could state “inertia is a property of matter”, or “density is mass over volume.” However, you struggled to apply it to a new situation and maybe you were unsure of how to construct a model of what it meant.
With a Master's degree in geology, I have a deep and abiding love for rocks and minerals. The great thing about geology is, it's all about chemistry! I want to share one of my favorite links between geology and chemistry that my students think is pretty cool too.
I am already planning for my trip to Illinois in July to attend ChemEd 2019! Let me tell you why I want to attend.
In an effort to align an old VSEPR lesson to NGSS, I told my students that we were going to look at the data available from the real molecules on the pHET simulation we were using and specifically look for patterns. Finding patterns is a cross-cutting concept; one of the three dimensions of NGSS.
AMTA’s Introduction to Modeling Instruction distance learning course will focus on the role of models and modeling in learning as it relates to teaching STEM content in both formal and informal contexts. Participants will review fundamental theories of thinking and learning and examine the latest theoretical trends.
I recently did a short activity with these cards and I am so glad I have them now. Being able to quickly take them out and have students look at the features of strong scientific arguments when they felt stuck writing their evidence or reasoning was powerful.
A favorite demonstration is to boil water by lowering the pressure in a bell jar using a vacuum pump. Unfortunately, purchasing a bell jar, vacuum plate, and vacuum pump can run upwards of $1,000 which poses a hardship for many teachers. Here are two simple and inexpensive demonstrations of phase equilibrium and vapor pressure.
Embracing the idea that students already create an image, create an idea, of what is happening when they observe a demonstration, lab or activity. The goal is to have the students make that model more concrete through drawing it.
In the summer of 2016, there was a Modeling WorkshopTM for High School Chemistry just before BCCE in Colorado. I already had planned to go to BCCE, so I took the plunge. Two weeks of daily instruction and labs in student mode as well as teacher mode debriefing was exhausting and exhilarating at the same time. I left with a folder and flashdrive of curriculum resources provided by AMTA (the American Modeling Teachers Association.
As a secondary science teacher, I have contact with my students everyday. Making relationships and learning about all of my students is key to letting them know that I am invested in their success.
