The Starter Series

Kinder-friendly science, built for small hands

The Starter Series takes the same projects families already know and rebuilds them for ages 5 to 7. Shorter builds, picture-led instructions, and science that lands in one sitting rather than one afternoon.

Three specially curated boxes make up the series, nine projects in total. Every box arrives with all supplies pre-portioned and included.

STEM Starter Series

3 specially curated boxes to choose from!

  • A boy pointing at a rack of test tubes filled with coloured liquid on a kitchen counter
  • Two young children in tie-dye shirts on a porch with trays of a science project between them
  • A girl holding the yellow bouncy ball she made over a plate of leftover crystals
  • Two small children using pipettes over trays of blue liquid at a table
K-2 Starter Box Series 1: a prehistoric crystal garden, glowing bouncy balls and a straw engineering structure

What's included

Starter Box, Series 1

  • Grow Prehistoric Crystal Garden

    Capillary action, evaporation and crystallization bring your prehistoric setting to life. Grow a one-of-a-kind crystal garden right before your eyes.

  • Create Glowing Bouncy Balls

    Explore chemistry and physics while getting creative with color. Make one-of-a-kind bouncy balls while learning about luminescence, elasticity, phosphor, potential energy and kinetic energy.

  • Engineer Geometric Structures

    Design and build an infinite number of geometric structures. Test your engineering abilities and challenge others. Think outside the box and let your imagination soar.

K-2 Starter Box Series 2: sensory magic sand, a fossil casting and a foaming fountain

Starter Box, Series 2

  • Explore Sensory Magic Sand

    Dive into the science of hydrophobics while being mesmerized by its water-repelling power. Can you put sand in water and have it come out dry?

  • Pour your own Fossil Casting

    Study the science of paleontology and fossilization by creating your very own fossil castings.

  • Mix up a Foaming Fountain

    Make a catalyst and create a spewing, frothy foaming fountain while experimenting with the science of exothermic reactions.

K-2 Starter Box Series 3: fizzing color chemistry, glow art with a spinning top, and bubbles inside bubbles

Starter Box, Series 3

  • Erupt Fizzing Color Chemistry

    Become a chemist as you experiment with acids and bases. Learn about indicators, pH levels and carbon dioxide while exploring colorful, fizzing chemical concoctions.

  • Disappearing Glow Art

    Create art while learning about Albert Einstein's photoelectric effect. Draw pictures, write secret disappearing messages, and decorate a glowing top, all with the power of light.

  • Create Bubble Sculptures

    What's cooler than bubbles? How about bubbles inside bubbles, inside bubbles. Using the science of surface tension, you can create challenging one-of-a-kind bubble sculptures.

Which box will I get?

The series cycles 1 to 2 to 3 and repeats, so your first box will be whichever box is currently shipping. Your first box may be Box 1, 2 or 3 depending on when in the cycle you subscribe.

Why the Starter Series

Built for how 5 and 6-year-olds actually work

  • A smiling boy holding up the fossil casting he made

    Independent success

    They want their child to feel like they did it, even if a parent helps.

    • Sensory Exploration
    • Observation
    • Sorting/Classifying
    • Patterns
    • Cause/Effect
  • Glowing handprints on glow paper under a violet light

    Fast wins

    Most 5 and 6-year-olds cannot stay focused for 30 to 60 minutes per build. They need:

    • 10 to 20 minute builds
    • Immediate results
    • Minimal precision
  • A small child stirring a mixing cup at a kitchen counter

    Low reading demand

    • Mostly picture-based instructions
    • Short steps
    • Easy to grasp science concepts
  • A boy painting with a row of small paint pots on a kitchen counter

    Frustration-free

    Let them explore chemistry, physics, and more in their own age-appropriate ways.

From our families

Young scientists at work

  • A girl sitting inside the straw structure she engineered, as tall as she is
  • A girl pouring through a funnel into a rack of test tubes on a tray
  • A boy with blue foam up to his wrists in a tray of foaming fountain mix
  • A young girl lifting purple and green polymer worms out of a cup with her fingers, her little brother beside her

In their words

What families say

  • My son loves his STEM Discovery Box

    Each month brings 3 hands-on projects we do together: fun, educational, and age-appropriate. The experiments have become one of our family's favorite activities.

  • These boxes are amazing

    My students were fully engaged and couldn't wait to explore each project. Clear directions, awesome results, and tons of learning packed into every box. Highly recommend.

    Customer review shared with STEM Discovery Boxes

  • Almost better than Disney

    Got this for my grandson and he said the only thing better would be Disney. He's made VR goggles, a hydraulic claw, and more. Creative, exciting, and absolutely worth the money.

    Customer review shared with STEM Discovery Boxes

  • Perfect gift for curious kids

    My daughter built glowing bouncy balls and a VR viewer, all by herself. Easy-to-follow instructions explain the science behind the fun. We can't wait for next month.

  • Science for the whole family

    Our grandkids look forward to every delivery. The experiments are fun for all ages, even grandpa joins in. It's the best bonding time and an incredible way to make science exciting at home.
