When introducing acid-base theory, the concept of indicators and their pH color changes is usually discussed. To illustrate some color transitions to students, a classroom demonstration has been devised based on a memorable scene from Disney’s 1964 movie Mary Poppins.
Helping students develop abstract understanding is a universal goal. This article describes an activity that involves students developing and then solving novel quantitative chemistry problems following a MadLibsTM style framework.
Summertime means doing chemistry experiments with flowers found growing in the yard...
Get to zero by becoming neutral. In using this method, let chemistry bring together broader ideas from math, economics and wherever value(s) are expressed in the negative.
After teaching the concepts and calculations for acid and base strength, concentration, percent ionization, and pH I noticed many of my students were struggling to make meaningful connections between these calculations.This lesson was created to strengthen the understanding of the relationships between these concepts and skills.
Many of us have molecular kits we only use once a year. Dust them off and find new lessons to use them in!
In this virtual activity, a video introduces stoichiometry and guides students to think conceptually using a simple baking analogy. Afterward, stoichiometry calculations connect to the analogy, that are then reinforced with a simple experiment. Finally, students explore a PhET simulation to deepen their knowledge.
What's a better way to start the new school year than with some new experiments? Learn how to use a variety of color changing experiments to teach students about the Diet Coke and Mentos experiment, acids, bases, chemical and physical changes, and climate change.
In “How strong an acid is vinegar?” the students explore the nonlinear relationship between the concentration of a weak acid and the pH of the solution. This formative assessment targets the question “how does structure influence reactivity?” Students need to understand the behavior of strong and weak acids to comprehend phenomena like buffering capacity.
Teaming up with a STEM Science Coach or mentor can be rewarding to both you and your students. I was surprised at the impact a science mentor has on students when I recieved an email from a former student.
