Why We Love It

Science doesn't just belong in the classroom! No matter the topic, from polymers and putties to electronic circuits and outer space, conducting science experiments at home teaches kids how to ask questions, formulate hypotheses, follow detailed instructions, work with units of measure, practice observation, and assimilate new information into their existing knowledge bank.
