Can I learn offline?

Yes, in a couple of ways.

Save lessons as PDFs (website)

In any lesson or project, open Options and choose Save as PDF. Your browser's print window opens, set up to print just the lesson. Choose Save as PDF to keep a copy, or print it on paper. Project solutions are left out, so printed copies work well for classrooms.

Download courses (STEMpump App)

In the STEMpump App, open a course and tap Download in the toolbar, or touch and hold its card and choose Download. Downloaded courses have a small arrow after their title.

  • Downloads include lessons, quizzes and projects. Videos and camps need an internet connection.
  • When you're offline, the app shows your downloaded courses so you can keep learning.
  • Find and remove downloads under Library › Downloads, or remove them all in Settings › Remove Downloaded Courses.
