Lessons from the Early College High School Model
Josh Kenney | Thu, 05/19/2022 - 12:13
Early Middle College High Schools are growing in popularity. They are an alternative public high school program where students earn up to 60 college credits while completing their high school diploma. Here, the author describes some lessons learned while teaching at an early college programs that help prepare students for college and careers.
Climate Science Concepts Fit Your Classroom (a 2-hour workshop)
Scott Donnelly | Sun, 05/15/2022 - 17:00
This 2-hour virtual workshop demonstrates how to use climate science concepts as a context for topics already in covered in your courses. The workshop will explore how incorporating climate science in your classroom extends to community effects.
KoolAid and similar drinks as convenient laboratory reagents: The weak acid-strong base titration of citric acid or malic acid
David Cash | Fri, 05/13/2022 - 08:06
The major component of a non-carbonated drink such as KoolAid or a similar beverage is usually a fruit acid, either citric acid or malic acid. The titratable acid (H+) concentration of such drinks has been found to be in the range of 0.02 to 0.04 M. A weak acid-strong base titration of these drinks with 0.1 M NaOH solution is feasible as a student exercise. Phenolphthalein indicator may be employed so long as the drink is not intensely coloured. The use of such drinks as reagents is safe, convenient, and inexpensive. Experiment instructions are included.

Too Hot to Handle? Hydrogen Reacts with Oxygen on Palladium Foil
Dean Campbell | Thu, 04/28/2022 - 20:50
The reaction of hydrogen and oxygen gases to form water is well known to be an exothermic reaction. That reaction can occur by first absorbing the hydrogen into palladium metal, and then placing the resulting palladium hydride into contact with oxygen in the air. Infrared and visible light videos were recorded for this process involving palladium foil, and the Green Chemistry and safety aspects of these activities are considered.
