This article describes a game aimed at helping students become comfortable using dimensional analysis. Designed to mimic the popular card game UNO, MOLE-O encourages students to think about how to set up a stoichiometry problem utilizing a deck of UNO-like playing cards.
Engage students in organic chemistry with a simple one-pot synthesis using the Mannich condensation reaction. This hands-on lab reinforces key concepts like reaction mechanisms, chromatography, and yield calculations, making abstract ideas tangible while building essential lab skills.
Explore a chemistry activity designed to have students measure quantities and calculate the moles and number of particles contained in the sample.
In this ChemBasics Talk, Krystle Moos offers everything necessary to plan a unit on the topic including linked NGSS standards, introductory activities and handouts, manipulative activities, practice problems, links to real world context, a lab and an assortment of videos. Watch the recording and access resources she shared.
Krystle Moos will present materials she uses to teach the mole concept. Breakout rooms and discussion will follow the presentation. Register to join us for this hour long Zoom meeting.
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.
In this activity, students learn about the mole. In section 1, students learn what a mole looks like for different substances. In section 2, students learn how the number of protons and neutrons in the nucleus determines the molar mass of an element by comparing individual isotopes in a PhET simulation..
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.
Inspired by Ben Meacham's post on stoichiometry, I looked to modify the lab sequence for my IB Chemistry class for our unit on stoichiometry. I will describe my experience modifying a typical empirical formula lab, along with using a modified version of the lab Ben shared.
A raspberry pi is the one of the world's cheapest computers. It is a $35 computer that runs off of an eight gig SD card. Anyone can program it with Python (a relatively simple coding lanquage) and it can do small things.
