Density and Measuring

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.  

Measuring Activity

I want to share a measuring activity for you to consider. First, start with two baseballs. The first baseball is a regular baseball. The other baseball is called a "small ball". Next, get six to eight students to volunteer. Without talking at all the students must hold the normal baseball and the small ball. They then must decide if the normal ball has more, less or the same mass as the small ball.

The Teacher Page - An Organizational Tool

The Teacher Page includes all of the notes I need to set up, run, and clean up the particular experiment. I record from whom I obtained the lab. I list the location of chemicals in the stockroom. I've added what does and does not work, so that I don't have to remember it from year to year. I have notes of things to try in the future. The most important part, however, is the giant spreadsheet to calculate amounts of chemicals needed to make multiple volumes of solutions. This saves so much time and repeated effort!

Creating a Culture of Nerdy

Bravo Nerdy awards

It all started with a couple of summers spent on fellowships at the Institute for Chemical Education at the University of Wisconsin: Madison. In 1990 after two years of teaching high school chemistry I transferred to help open a school to specialize in Health and Medical education. I was 23 years old and ready to take on the world. The school’s student body was high poverty, 96% of the students qualified for the federal lunch program, and almost the entire student body was classified as minority. It was a good first year.

The Two Words Every Chemistry Student Needs to Learn

Teaching students the proportional reasoning skills needed for stoich doesn’t have to be that daunting. By adjusting how your students talk about stoich, you will adjust how they think about it; eventually, they’ll proportionally reason in a more effective manner.

Dance Your Final Project

As part of advocating science literacy in my classroom, I have my 10th grade Honors Chemistry students dance their first semester final. This Dance Your Final semester final is to force students to actually read real, published scientific research; have a group final; eliminate test anxiety; and help students have fun with the content. Truly, of all assignments I give during the school year, this is the one that students say they sweat the hardest on, enjoy the most, and are the most proud of their work.

Stop trying to get your students interested in chemistry!

Because my teaching philosophy assumes that both quality and quantity of learning increases with interest in subject matter, I have spent years exploring ways to engage my students in chemistry (of course fire, explosions, and color changing reactions are certainly helpful). I have recently begun using an approach that I have found to be quite fruitful, albeit counterintuitive: I don’t try to get my students interested in chemistry. You read that right. I don’t try to interest my students in chemistry. Rather, I get to know the hobbies and interests of my students. Then I work to demonstrate how chemistry relates to those activities.

Periodic Table Websites and Apps - An Update

Periodic Table of Tech

With the start of the school year quickly approaching or having already started for others I wanted to take this chance to update a few resources regarding some periodic table websites and apps for you and your students.
