ChemEd X activities are student-centered resources intended to aid learning chemistry topics.
ChemEd X encourages engaging activities where students (with guidance from the teacher) pose questions, analyze data, and make observations to offer a plausible explanation supported by data and consistent with physical observations.
In this activity, students learn about solubility and concentration. They watch videos that explain the dissolving process, how to calculate the molarity, supersaturation and how to make rock candy. They also use a PhET simulation to explore factors that affect the concentration of a solution.
In this activity, students express their creativity and show their understanding of concept by creating a video for their final project.
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..
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.
Spectroscopy-based experiments are commonplace in college labs. This out-of-classroom activity post provides links to applications of spectroscopy in a diverse spectrum of disciplines and work fields.
In this lab students are given a film canister, a quantity of Alka Seltzer of their own choosing and any materials available in the room to investigate factors that affect the rate of reaction. They work with their groups to create CER boards and then the class engages in a Glow and Grow session. Tips for using this activity in a virtual setting are offered as well.
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.
Using the online simulation tool (Atomsmith Classroom Online) and the ADI framework students investigate the properties of gases, along with two gas laws. An ADI "whiteboard discussion" helps in getting students to really process what the results of experiments mean to us as chemists - and how this leads to expanding our understanding of matter. This activity lends itself to an online classroom.
This puzzle is developed by students and a faculty member of Valdosta State University during the Coronavirus pandemic that has brought the world to a standstill. It blends a novel approach to puzzles with an educational activity to serve as a learning tool for infectious diseases. While there is a strong strategic aspect to solving or completing the puzzle, it should also familiarize the participant with the names of infectious diseases and a few facts about each malady.
Ever wonder why some call precipitation reactions "double decomposition". Perhaps (or perhaps not) two (double) salts are sort of splitting apart (decomposing?) and then reforming with other radicals. But a solvent (usually water) is necessary to achieve the desired effect. But is adding water to a salt really decomposition?
