Try out our out-of-school time units:
While PLANETS science and engineering units were originally intended to be led by educators in out-of-school time with groups of youth, these activities can be modified to be more self-directed using educator instructions. The materials are mostly available at home – requiring few specialty items.
Please contact planets-stem@gmail.com for questions and/or modification suggestions.
