STEM Discovery Boxes
Updated
Three NGSS-aligned STEM projects with all supplies, every month, for ages 7-12+
STEM Discovery Boxes delivers monthly science for kids aged 7 to teen, roughly grades 2-8. Each box includes three STEM projects or experiments, and all the supplies come in the box, so there's no hunting for materials before you can start. Projects span electronics, chemistry, physics, coding, hydraulics and more. The activities are aligned with the Next Generation Science Standards, covering disciplinary core ideas, science and engineering practices, and crosscutting concepts, which makes the box a solid complement to school science. It has won a Parents' Choice Award for subscription boxes and was named "Best for Family Projects" by STEM Toy Expert. Past projects show the hands-on approach: - **VR goggles:** build your own virtual reality viewer - **Glowing bouncy balls:** explore luminescence, elasticity and potential and kinetic energy - **Balance bot:** engineer a rolling bot that never tips over while learning about center of mass - **Hydraulic excavator:** build a digger powered by hydraulics Your first box ships within 1-3 business days of ordering, from the United States, and the listing shows free shipping. You can pay monthly or prepay 3, 6 or 12 months for a lower per-box price. It's a strong pick for curious kids who like to build things, homeschool families looking for ready-made science units, and parents who want weekend projects to do together.
