Marianne Knowles delights in crafting curricula to inspire the next generation of science enthusiasts—and she’s been doing it for over 20 years, so that’s a lot of enthusiasts. Before becoming a Marble she was freelancing, doing everything from conceptualization to editorial project management to assessments and lots and lots of writing and editing of science, engineering, and math materials. Prior to that, she was an Executive Editor with Great Source/Houghton Mifflin Harcourt, where she directed the development of supplemental learning materials for math and science. She has a BS in Geology from the University of Maine and has done coursework in instructional design and digital materials development at the University of Massachusetts.
Once, while Marianne was testing a set of life science activities, her house hosted frogs, ladybugs, lizards, goldfish, guppies, earthworms, mealworms, crickets, mice, two kinds of snails, and assorted plants, almost all at the same time. Only the frogs and the ladybugs got loose.
