In this blog, Michael Jansen considers the significance of using proper units and their role in helping students develop a conceptual understanding of Chemistry.
Ryan Johnson and I took a trip to the top of Pikes Peak to study the Coke and Mentos experiment. And we had a few surprises along the way...
Students may have been using the metric system as early as in elementary school, so why do they struggle to use it in first year chemistry class in high school? This is a quick idea to help you reintroduce the metric system in your class.
The concepts of Measurement and Significant Figures can induce discomfort for both teacher and students. Michael Jansen shares his approach to teaching this important topic.
Explore how small the stuff that makes up matter is and consider what those tiny particles are doing in this engaging activity.
We were converted; we saw the light. No more playing with a balance. Reverence, dude. Without a balance we got nuthin’.
This activity allows students to see many different types of scales in order to become proficient at measuring and determining how many digits to record in any measurement, whether it be volumes, masses, lengths, etc.
The author explains a virtual chemistry lab activity for use in a high school chemistry class. This activity is an excellent way to introduce measurements, significant figures, and the concept of density.
As high school teachers, we know that understanding how measurement works is crucial for lab skills and for understanding significant figures. We think measurement should be an easy topic for students to learn; especially because we know that teachers begin working with students in elementary school to teach these skills. However, I, and many other teachers, have spent countless hours teaching and reteaching a seemingly simple skill.
It can be difficult to engage students in reviewing for semester exams by using worksheets or practicing problems on the whiteboard. If you are looking to change up your review plans, you might consider using a lab activity that provides opportunity to revisit many of the topics that need to be covered.
