HISD teachers attended their first “STEM Reboot” session earlier this month at Ryan Professional Development Center, where Teacher Development Specialists from the Innovative Curriculum and Instruction Department guided team through a series of hands-on experiments. As part of the science, technology, engineering, and math training, they were challenged to create a hot air balloon from a variety of materials, including plastic cleaners’ bags and tissue paper, and build boats out of aluminum foil that could float while supporting a penny. In addition, the teachers had a rocket-building session and were trained in an Hour of Code.
