Quick answer

The Circuit Blox 395 Project Classroom Set is a comprehensive STEM kit for grades 4-6, containing four Circuit Blox 395 sets in a sturdy storage case with a 126-page teacher guide covering electricity, motors, light, sound, switches, and telecommunication.

What makes this set different from smaller Circuit Blox kits

Unlike single-project sets, the Classroom Set bundles four identical Circuit Blox 395 kits so multiple students or groups can work simultaneously. The included storage case keeps everything organized for reuse across lessons.

The 126-page teacher guide is the biggest differentiator. It provides structured curriculum, quizzes, and answer sheets aligned with NGSS standards, saving you planning time for a full unit on circuits and electronics.

Trade-off: Is this set right for every classroom?

The advanced concepts (motors, FM telecommunication) target grades 4-6. Younger students may struggle without significant teacher scaffolding. Also, the set does not include consumables like batteries or additional building materials—plan for those separately.

Decision rules for the Circuit Blox 395 Classroom Set

  • Grade level match: The curriculum is designed for grades 4-6. If your students are outside this range, expect to adapt lessons or provide extra support. Check your students' prior experience with circuits before ordering.
  • Number of students: With four kits, the set works well for up to 8-12 students working in pairs or small groups. For larger classes, consider purchasing multiple sets. Plan for one kit per 2-3 students for hands-on participation.
  • Curriculum alignment: Lessons address NGSS requirements and cover electricity, motors, light, sound, switches, and FM telecommunication. If you need a specific topic not listed, this set may not cover it. Review the six lesson topics to ensure they match your teaching goals.
  • Storage and reuse: The sturdy storage case keeps all pieces organized for repeated use. However, the set does not include batteries or other consumables, which you must purchase separately. Add batteries and small tools to your classroom supplies list.
