Melda Scientific (1999-2006)

Lab-based chemistry course curricula

Explore newly released course curriculum archives from Melda Scientific courses taught in Rochester, MN from 1999 through about 2006. Composed of only 2-5 sessions, these were the first pilots of so-called burst education. [All files in PDF format]

Make bubbles, grow mold, dissolve stufff, and analyze crystals left over from evaporated solutions made with household solutes. While not linguistically tight, this manual was the foundation for the Crazy Chemists successful multi-day science class series.

The poor quality of the copy machine at the corner gas station does not do justice to the exciting series of lab procedures this guide outlines.

This course guide formed the basis of dozens of extra-curricular chemistry classes designed for students ages 10-14 held in Melda Scientific's 2126 Lab in Rochester, MN from 2002 through 2005.

Melda Scientific founder teamed up with the CEO of Electro Explorers to offer Rochester summer students a five-day, action-packed summer science exposure camp complete with the decarbonation of surcrose by fourteen-molar sulfuric acid!

Over two after school sessions, students were guided through the construction process of the Estes Corporation's Gemni-DC model rocket kit. Students and families met in a park on the Saturday following the class to launch their creations hundreds of feet into the air.
