Program Description
Twig Science is a comprehensive, phenomena-based science curriculum for Grades K–8 that follows the 5E instructional model (Engage, Explore, Explain, Elaborate, Evaluate) and aligns with the Next Generation Science Standards (NGSS). It emphasizes student inquiry, integrates science and engineering practices, and includes multimedia-rich investigations, collaborative tasks, and built-in literacy supports.
Program Outcomes
A 2024–25 quasi-experimental study conducted in one rural Iowa school with nearly 400 students evaluated the impact of Twig Science on middle school students’ science proficiency. Using matched comparison groups and controlling for baseline achievement and demographic variables, the study found that students in Grades 6–8 who used Twig Science showed significantly greater gains on the Imagine Galileo science benchmark assessment than their peers who did not use the program (effect size = +0.15), earning Twig Science a Promising rating.
Staffing Requirements
Each implementing classroom needs one instructional teacher. No additional staffing is required.
Professional Development/Training
In addition to support from the Customer Success team, Imagine Learning offers various virtual and on-site professional learning for teachers and administrators. Sessions for teachers and administrators include learning how to use Imagine Learning digital platforms and Twig Science curriculum training (the latter varies by grade level and district needs).
Technology
The curriculum requires networked computers with mice or tablets and access to the digital platform (though not required as print materials can be purchased by the district).
