About This

• TEACHERS SAVE TIME: Empower a classroom of 30 students, working in pairs, to tackle STEM challenges with this classroom set of Catalyst Kits. Well-structured lessons and all required supplies allow teachers to hit the ground running. Three units are available for grades 3-6 (up to 30 class sessions!), and one unit is available for grades K-2. Everything you need is in the box, from batteries to brainstorming paper.
• HANDS-ON INVENTING: Using materials found in real machines, students experience what it’s like to be inventors, not just builders. Engage students in engineering using authentic materials—wood parts, screws, wingnuts, and L-brackets—paired with motors and battery packs to create working circuits. Students quickly see how everyday hardware connects to scientific principles, making abstract concepts tangible.
• SCREEN-FREE ENGINEERING: Students practice engineering design and physical science NGSS standards without devices or logins. Foster collaboration and focus, free from digital distractions, creating a more connected and creative classroom environment. Incorporate recommended reference material to deliver a robust lesson that meets students at every experience level.
• GOAL-DIRECTED: With 10 unique challenges, students get direction without step-by-step instructions, encouraging them to problem-solve and think creatively. Spark innovation with creative prompts and see what students will invent!
• QUICK BUILDS, LASTING ENGAGEMENT: Challenges can be started and completed within a class period, but students are motivated to keep tinkering. Catalyst is reusable and open-ended. It's designed to be made, unmade, and remade—again and again.
