Generate and compare multiple possible solutions to a problem based on how well each is likely to meet the criteria and constraints of the problem.
The West Virginia College- and Career-Readiness Standards for Science (Policy 2520.3C) outcome S.5.16 (Engineering, Technology and Applications of Science) for Grade 5 says: “Generate and compare multiple possible solutions to a problem based on how well each is likely to meet the criteria and constraints of the problem.” This Fieldbook unit teaches it hands-on, with everyday materials and a printable teacher guide and student sheet for every lesson. Official wording: West Virginia College- and Career-Readiness Standards for Science (Policy 2520.3C).
Living with Water: Salt, Rice and the Mekong Grades 4–5
Science and English together, for English learners (CEFR A2–B1). Three investigations from Vietnam: how salt farmers turn the sea into salt, how rice terraces stop a mountain washing away, and how a house in the Mekong Delta stays dry in the flood season.
- How do salt farmers turn the sea into salt? 60 min, plus a 10-minute check the next day
Science and English together, for English learners at CEFR A2–B1. Teams paint salt water on dark paper to find the salt hiding in sea water, then set out wide and narrow dishes in sun and shade to see what makes water leave fastest. They use the evidence to advise a salt farm in Khánh Hòa.
- How do rice terraces stop a mountain washing away? 60 min, or two 35-minute periods
Science and English together, for English learners at CEFR A2–B1. Teams make model hillsides from soil in trays: a bare slope, a terraced slope and a slope with plant cover. They pour the same storm of rain on each, measure the muddy water that runs off, and use the evidence to advise a mountain village in northern Vietnam.
- How can a house stay dry when the Mekong floods? 60 min, or two 35-minute periods
Science and English together, for English learners at CEFR A2–B1. Teams design and build a model house on stilts or on a floating base, then test it as the teacher raises the water in a tub and makes waves. They use their results to advise a village in the Mekong Delta.
