An Elemental Understanding of Isotopes

In this activity, students can look inside the model that resembles the atom and find information that reinforces what an isotope actually is. Furthermore, the quantitative data forces students to examine beliefs about different types of averages and what the numbers really mean. This takes a bit of effort to set up but is inexpensive and can be used year after year.

That’s What Scientists Do!

As I began to prepare my labs for this upcoming year, I decided to put a bit of a twist on a previous density of a block lab I had used in the past entitled the Measurement Challenge that is sold by Flinn Scientific. It can also be used to find the mass of a block given the materials density and requiring students to measure and calculate the blocks volume. My added twist resulted in great scientific discourse. 

My Research: Unpacking Active Learning

Does flipping the classroom actually enhance students’ learning, above and beyond just incorporating collaborative activities into classroom instruction? John Moore, one of the chemistry professors at my university, the University of Wisconsin - Madison approached me with this question. We ended up conducting a research study on one of his chemistry courses.

Density and Measuring

If you are looking for a measuring and density activity that will be challenging, allow students to experience success early on and can be boxed up to use again, you might consider trying the activity that I am sharing in this post.  

My First Lab of the Year

My first experiment involves measuring the density of water. Each group of two kids is assigned a specific volume of water from 10 to 100 mLs on the tens. They simply measure the mass of an empty graduated cylinder and then add the water and find the mass again. Once they have their data they go around the room and find another group that has one of the volumes that they need and get the data from them and record their names. Once complete they generate a graph of the data and answer a few simple questions. The whole procedure can be completed in about 20 minutes.

Building a Blended Culture in a Secondary Science Classroom

During my first year of teaching (in Indianapolis, IN), I was inspired by some research I had read as well as some other teachers in the Indy area who were flipping their classes. I was at a small parochial school where parental and administrative support for technology inclusion was present. My principal outfitted me with the tools I needed to “flip” my classes and record tutorial videos. Things went pretty well. It was a learning curve for many but I also had good feedback from students and parents.
