Bringing Chemistry to Life
This activity aims to boost students’ confidence in representing the atomic world. It also aims to educate both students and the general public about the “chemicals” found in everyday objects.

This classroom activity challenges students to figure out the volume of gaseous carbon dioxide emitted from the combustion of 1 gallon of gasoline fuel.
If a student “gets the wrong answer” while performing mole conversions, it can be difficult (for both student and the teacher) to discern where an error was made. Inevitably sometime toward the beginning of learning these conversions, students can become overly confident, plugging numbers in without thinking about whether they are sensical. This card set slows students down to think about the order and purpose of each of the steps in mole conversions.
This virtual adaptation provides students the opportunity to engage in a process similar to the one Mendeleev used as he constructed the original version of the periodic table we still use today.
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.
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.
The author explains how she assigns roles for her students while completing laboratory work. The lab activity is designed to allow students to explore the use of indicators. It serves as an introduction to acids, bases and pH.
Looking to change up your titration lab? Citric acid is very common in candy and other foods. Students will be engaged in using titration to find the amount of the acid in Mentos Now or other candy. Student and teacher documents are provided to help you use the activity with your own students.
As many teachers are preparing for the possibility of teaching online next semester, we are revisiting posts from the ChemEd X archives like this one that might be of help. The author has updated this activity by adding notes specifically to help those teaching remotely. - Radioactivity is a topic in chemistry that can be difficult to teach. This activity offers a data-driven approach with a simulation students can use in school or in an online learning environment. This can be used to give students an authentic lab experience for them to determine there are three types of ionizing radiation without direct instruction.
