Website of the Week: The Blobz Guide to Electric Circuits

The Blobz Guide to Electric Circuits – How do they work? (Gr. 3-6)

This interactive site introduces students to the concept of electric circuits and leads into the related fields of conductors, insulators, switches and more. Each of the five sections includes an information section, a game/activity segment, and finally a multiple choice quiz. Throughout the site important words are highlighted in red and can be clicked on to reveal additional information. Students must earn a score of at least 4 out of 5 on each segment quiz in order to receive a star award. Students who earn all five stars will advance to the bonus stage of the site.


  • Use this site to introduce the concepts of circuits before starting the hands-on lab activities. This site can also be a great alternative when obtaining actual lab equipment is a financial hurdle.
  • Use the site as a review at the end of the unit. Have students go home and take the quizzes with their parents to bring them into the learning.
