Though we may recognize its presence, teachers, scientists, and policymakers still disagree on the most practical and effective methods for developing scientific literacy in our students. Herein lies our challenge as science educators—what can we do in the classroom to create experiences for our students that involve the understanding and appreciation of the most valuable traits associated with being scientifically literate? This article includes resources and a sample assignment that will hopefully get all of us off on a good start.

As we all know, research and general educational practice clearly indicates that students learn science best by doing it – not just reading about it. Hands-on, process and inquiry based science is the key to understanding science. Unfortunately, this is a double edged sword for science teachers in that doing science has its potential hazards and resulting risks. Science laboratories, classrooms and field work sites can be unsafe places to teach and learn. If a student gets hurt while doing an activity in the lab, in the field or even at home if it was a teacher’s assignment, there is potential shared liability for both the teacher and the school.

A classroom activity to demonstrate the principles of chemical kinetics and equilibria and the utility of the mole concept is described here. The activity involved no hazardous materials or complex equipment and can be enjoyed and appreciated by general studies students as well as chemistry majors.

Chad Hustings blogged this past school year about building his own Hoffman apparatus for each group of students. I have been using a Hoffman apparatus that had been purchased by my district before I began teaching there over 20 years ago to demonstrate electrolysis of water, but providing each student group with the ability to perform an electrolysis themselves is a powerful activity. I have used a different version of a homemade Hoffman apparatus, but after reading Chad's blog post, I decided to use a version close to his.

My first year teaching chemistry, I was looking for a soap-making lab or activity that I could run in my chemistry class with 25-30 students working at the same time. I usually do this activity right before spring break, as it provides enough time for the soap to harden and cure (high school students are impatient to use their soaps right away, which you should not do with cold process soap). I have used the activity at different points in the curriculum: during intermolecular forces, during acids and bases, and during stoichiometry. Although I know teachers who use soap making as a project during their stoichiometry unit, I chose to not emphasize the calculations as it would require more time than I have available. Simply making the soap easily fits in a 45-minute period.

In a recent post, I shared sample quiz questions as to how I have differentiated assessment within the mole unit. Here, I share a specific multi-day sequence within the stoichiometry unit. I have written extensively about the project that drives this unit (within the following blog posts: Why consider trying project based learning?, Backwards planning your PBL unit -­ An Overview of an Entire Unit and What ARE my students actually learning during this long term project (PBL)?), but very little about specific learning tasks. Below is a two day sequence of stoichiometry practice that I set up in my classroom. Stations are set up around the room and students rotate as necessary.
