Students carry out research into parts of a banjo. They build a banjo by testing different banjo parts and argue from evidence which materials make the best banjo sound.
Students define the problem of saving the sand towers from destruction caused by water. They design a solution that is based on understanding of all the components of the system the sand towers are a part of and that works within set limits and is based on evidence from prior tests.
Students define the problem of salamanders being killed on roads and work together to design a prototype that, as a complete system, meets the constraints and criteria of the problem.
In a written assessment, students design a solution for a family interested in installing solar panels. Their solutions weigh environmental effects and use models of energy flow. Groups begin their design challenge, developing a plan for solving the problem and using models to document their plan.
Groups of students evaluate information about a specific town in order to design a solution for accessing and treating water that meets specified criteria and constraints. Students analyze and interpret data to figure out effects of design choices in previous testing.
Students analyze data from field notes about the environmental conditions in two streams where their guppies live and ask questions about their possible effects.
Students use data from testing with a model to develop an argument about whether fireflies with more distinct flash patterns are better at communicating.
Students analyze and interpret data to develop and compare food web models of matter and energy flow in two coastal ecosystems.
Students analyze and interpret patterns in climate data to make a claim about which month would be best to host a kids’ tournament in a particular city.
Students apply their understanding of evidence of change to new locations. They communicate information about patterns of fossils and rock features and patterns in map locations to explain that landscapes change.
Students engage in argument about the plausibility of Polynesians sailing long distances
without instruments by using evidence that the patterns of the Sun and stars can be used to navigate.
Students ask questions about how magnets affect the pattern of motion of a steel pendulum.
Students plan and carry out an investigation to determine how speed and surface affect how far an object slides in a collision.
Students carry out an investigation using a fair test to identify four unknown solids based on similarities and differences in properties.
