Identifying Organic Functional Groups Activity

molecular models

In a previous post I talked about an equation balancing lab that I have been doing with my students involving building molecular models. This time I would like to focus on another lab that I have developed for my model kits.

Time required: 

15 minutes prep and 30 minutes for students to observe the molecules.

Early Use of AP Insight with Honors Chemistry: Atomic Mass, Mass Spectrometry, and Dalton's Postulates

AP Insight

College Board offers an excellent online resource for teachers and students. It's not free, but my school district pays the bill. AP Insight provides curriculum outlines, teaching ideas and resources, student handouts, and digitally-graded assessments. I have elected to begin using the resources in first semester honors chemistry.

Using IUPAC's Isotopes Matter as a Digital Learning Tool

Isotopes Matter

Isotopes Matter is a digital learning tool, developed by IUPAC Isotopic Periodic Table, designed to explain isotopes as well as their importance. This resource incorporates mass spectroscopy data into each of the key ideas as well as provides multiple examples as to how varying isotopes are commonly used.

Time required: 

Using Isotopes Matter and the class discussion: 55-60 minutes

Tackling Big Ideas

BIG IDEAS

It was the empty terrible feeling in the pit of my stomach at 9:30 at night that really bothered me as I am wading through the stack of papers that I was grading. I had the students do experiments, worksheets, I lectured and there was homework. Some of the students could “do” what I thought was science. They could calculate the answer. They could balance the equation.

Significant Digits, Pool Tolerances, and Ties in Swimming

              With the Olympics just finishing up, I was excited to see the following link posted on twitter entitled: Significant Digits and Pool Tolerances are Why There are So Many Ties in Swimming. You see in my attempt to connect chemistry content to a real world application, I had used a scenario in an old YouTube video I had created
