Season Two, Episode 8: Getting Hands-On
Summary
In this episode of Chalk Dust, Rebecca Birch and Nathaniel Swain are joined by STEM educator Amber Haven to explore what happens when explicit instruction meets genuinely engaging hands-on learning. Using footage from Amber’s middle-school STEM classroom, the discussion follows a lesson on neutral buoyancy, revealing how carefully designed routines allow practical investigations to remain cognitively demanding rather than descending into chaos.
Amber demonstrates how retrieval practice, mini-whiteboards, Six Bricks, gesture, choral response and explicit behaviour routines work together to create classrooms where every student is thinking. Throughout the episode, Rebecca, Nathaniel and Amber discuss the importance of background knowledge, continuous checking for understanding, purposeful transitions, differentiation without lowering expectations, and designing practical activities that provide immediate feedback. The conversation highlights how high-quality classroom routines free students to focus on learning rather than logistics, making complex scientific concepts accessible through deliberate instructional design.
Mentioned resources and explainers
Amber Haven
Amber Haven is a STEM educator with more than 16 years of classroom experience and a strong focus on translating cognitive science into practical classroom strategies. She has presented at ResearchED conferences across the United States and at the Thriving Educators Summit, and her work has been featured by The Learning Scientists and in Powerful Classrooms by Patrice Bain.
Retrieval Practice
Throughout the lesson, Amber demonstrates retrieval as an ongoing classroom habit rather than a single lesson component. Students repeatedly retrieve knowledge through mini-whiteboards, questioning, gestures, closed sentences and practical activities.
Mini Whiteboards
Mini-whiteboards allow every student to participate, provide immediate formative assessment, and make thinking visible. Amber discusses the routines required to use them fluently throughout a lesson.
Six Bricks
Six Bricks is a hands-on retrieval strategy that uses coloured Duplo bricks to sequence concepts, definitions or problems. Students retrieve vocabulary while constructing a coloured stack, allowing rapid checking for understanding and high levels of engagement.
