Check out the schedule for upcoming ChemEd X Talks and ChemEd X ChemBasics Talks along with recordings of past events.
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.
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.
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.
Can Alkaline Water Change the pH of your body? We use chemistry to put this claim to the test!
This engaging activity uses wrapped and unwrapped candy to simulate alpha and beta decay.
In this blog the author describes how three components of a water tower reservoir is analogous to an acid-base buffer system.
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.
Many chemistry teachers use models and diagrams to help students describe how matter behaves at the particle level. On April 14, 2022, Doug Ragan explained how he uses colored magnets in his classroom to represent things such as subatomic particles, states of matter, balancing chemical equations, types of bonding, molecular geometry and much more. View a recording of his presentation and access materials he uses.
It can be frustrating when students are always on their phones. What if we meet them where they are at with some chemistry content? This is one teacher's journey into the world of Tik Tok.
