The document discusses transforming traditional science activities into open-ended design challenges. It advocates for giving students interesting, challenging problems to explore with creativity and critical thinking. Examples are given of traditional "recipe" style activities that could be modified to allow more room for student innovation and variable testing. Guidance is provided on setting up design challenges, supporting the design process, and assessing student work in new forms beyond traditional lab reports. The goal is to engage students more fully through hands-on, student-led exploration of concepts.
