STEM Inventions Catapult Kit – Build 30 Mini Catapults for Classrooms & Home Learning | Bulk STEM Project Kit

Overview

The STEM Inventions Catapult Kit is a bulk STEM project designed for classrooms, libraries, and families who love hands-on science. With material for 30 mini catapults, it turns a simple building activity into a rich, collaborative learning experience that can fit a wide range of groups and schedules. The kit supports group work, classroom rotations, and after-school programs, making it a flexible option for diverse learning environments.

What’s inside

• 350 large craft sticks
• 600 mini rubber bands
• 45 3M adhesive squares
• 30 cups
• 30 foam cubes

A complete classroom activity to assemble 30 toy catapults appears in the kit, enabling bulk projects and structured group work right out of the box.

Learning through play

Kids observe core science ideas in action as they build and test their catapults. Potential energy transfers to kinetic energy as launches occur, trajectories shift with angle and force, and levers reveal how small changes can influence outcomes. These open-ended experiences encourage observation, hypothesis, and discussion without claiming guaranteed results.

Easy-to-follow instructions

The kit ships with clear, full-color instructions featuring step-by-step photos. This design helps educators and kids stay engaged, reducing setup time and keeping focus on exploration, experimentation, and collaborative problem-solving.

Ideal for group activities

• Classrooms
• After-school programs
• Summer camps
• Libraries
• Birthdays and STEM-loving families

With supplies for multiple learners, it supports rotation stations, small-group challenges, and scalable activities that fit different spaces and schedules, inviting everyone to participate and contribute ideas.

Encourages creativity and exploration

The design invites experimentation with the fulcrum position and launch settings, offering room to test hypotheses and iterate designs. Children can explore how subtle adjustments alter paths, fostering critical thinking and collaborative problem-solving in a low-pressure environment.

Why choose STEM Inventions

This bulk kit blends practical materials with clear guidance, delivering a flexible platform for exploring core engineering ideas. It emphasizes curiosity, teamwork, and hands-on progress, helping learners connect concepts to real-world tinkering without promising specific outcomes.
