What is PhET?
Using PhET Sims in Chemistry
39 interactive simulations for teaching and
learning Chemistry.
Topics include atomic interactions, atomic composition, gas properties, pH, molarity and more!
Flexible: used from grade school through college.
Research-based and research-validated.
Free. Run online or download.
In Class
Concept tests: Which parts of the chemical
symbol will change when a proton is added
to this atom?
Class Discussion: Suggest ways we can
change this solution to block as much light as
possible.
Goals
Engage students in STEM practices
Develop expert visual and conceptual models
Coordinate across representations
Connect STEM to everyday life
Empower students to see STEM as accessible
and understandable
Peer Discussion: Compare the potential
energy wells between different pairs of
atoms.
Lab
Compare how adding light or heavy gases
affects the pressure in the container.
Homework
How did the chemical equation help you
find the number of “leftover” reactants?

About PhET
Acid-Base Solutions
How do strong and weak acids differ?
Use lab tools on your computer to find
out! Dip the paper or the probe into
solution to measure the pH, or put in
the electrodes to measure the
conductivity. Then see how concentration and strngth affect pH. Can a weak
acid solution have the same pH as a
strong acid solution?

• Describe how common tools (pH meter, conductivity, pH paper) help identify whether a
solution is an acid or base and strong or weak and concentrated or dilute.
