THE SCIENCE OF FORMULATING

Real science. Taught by making real things.

A 12-month homeschool science curriculum covering chemistry, biology, and botany — taught the way Katie Veldkamp learned to love science: by formulating, observing, and explaining what just happened in the bowl.

Real science. Taught by making real things.

WHY FORMULATION TEACHES SCIENCE

Kids remember chemistry they made with their hands.

Reading about saponification on a worksheet doesn't stick. Mixing lye with coconut oil at 110°F, watching it trace, and pouring it into a mold — that sticks. Every month of The Science of Formulating is built around one real product your kids make. The science concepts come from explaining what they just did.

BUILT BY A SCIENCE TEACHER

Katie Veldkamp wrote this curriculum.

Co-author Katie Veldkamp is a Certified Aromatherapist, former middle school science teacher, and homeschool mom of four. She built The Science of Formulating to be the curriculum she wished existed when she started homeschooling her own kids. Lab notebooks, parent guides, scope & sequence, and assessments — all classroom-quality.

  • Certified Aromatherapist. Trained in essential oil science and safe formulation.
  • Former middle school science teacher. Built the curriculum from a real classroom-first perspective.
  • Homeschool mom of four. Lessons tested with her own kids before they go in the box.

HOW IT FITS YOUR YEAR

About 2 sessions a month. One hour each.

Designed to fit *around* the rest of your homeschool, not take it over. Most families do one session every two weeks — Tuesdays and Thursdays are popular. Each month's box arrives 7–10 days before the lesson, giving you time to glance through the parent guide.
