For Educators
Free, no-account tools for your classroom, lab and tutoring. Students practice by doing, and you can use the same tools on the projector.
Use it in class
BondWorks
- Assign one tab as homework: ionic compounds, covalent compounds, acids or nomenclature.
- Each practice tab has 3 levels and a crown to win, with Hint, Reset and Skip.
- Use the Lab and Challenge tabs for review before a quiz.
CalcWorks
- Assign a topic tab as homework: sig figs, conversions, moles, balancing, stoichiometry, solutions or heat.
- Every problem is randomly generated with a worked solution, so each student gets different numbers.
- The Challenge tab mixes all topics for exam review.
ElementWorks
- Project a periodic trend and ask students to predict before you reveal it.
- Switch views to compare electronegativity, radius and ionization energy.
- Click any element for its full card, with electron configuration and orbital diagram.
Progress is saved on each student’s own device and the tools need no sign-in, so teachers cannot see class results yet.
