For dynamic equilibrium, I like to use a physical analogy that pits students against each other in a classroom-wide “snowball” fight. Not only is this activity great for building students’ conceptualization of dynamic equilibrium, it is also really fun!
Like most concepts in chemistry, intermolecular forces takes a bit of imagination and critical thinking to fully comprehend and apply when explaining a variety of situations. Though demonstrating the presence of these forces in a simple and explicit manner can easily be done, I wanted to change how I introduced IMFs a bit this year by focusing on a more data-to-concepts approach.
Whiteboards are great learning tools in a science classroom. With these instructions, you can make eight 24-in x 24-in whiteboards for less than $2.00 each! Instructions for simple whiteboard stands are included.
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.
