All the assessments in Twig Science have been carefully designed to be multi-dimensional.
Students use the three dimensions to make sense of phenomena and solve problems. They articulate their reasoning and explanations through written and drawn explanations, discussions, and presentations.
Of particular note are the Summative Performance Tasks, which are present in all modules and wrap up instructional blocks, requiring students to demonstrate their ability to meet specific PEs. For example, in Grade 1 Module 1 (DQ3L6 Investigate TE p. 114), students meet the PEs 1-LS1-1, K–2-ETS1-2, and K–2-ETS1-3. They do this by comparing different seeds, gathering information of how seeds disperse, and solving the engineering design problem by designing, building, and testing their own a seed model that can be dispersed by the wind.
Every Module in Grades 3–6 also contains Benchmark Assessments, developed in partnership with the Stanford Center for Assessment, Learning, and Equity. Students are challenged to apply the skills and knowledge acquired in the module to new contexts.
