What is SWH

• Science Writing Heuristic• Guided inquiry• Writing to learn strategy• Used to promote

collaboration, learning, critical thinking skills, communication, & problem solving

Why SWH? NRC says:

• Students need to investigate• Students need to gain

evidence for their claims• Students need to compare

their findings to those of peers, others

• Students need to communicate and defend their findings

What students DO when using SWH …

• Design and carry out labs based on their questions

• Make claims based on evidence• Share what they learned with

peers• Compare their findings to those

of the scientific community• Reflect on their experiences• Apply new ways of

understanding
