These nine short videos show the third and fourth lessons in a 10-lesson third-grade magnet unit. In lessons prior to this video record, the students and teacher have observed and discussed the attractive property of magnets with respect to different materials, and have planned an investigation on the relative strength of two kinds of magnets.
This record begins with students setting up and conducting the investigation they planned previously. Before the investigation begins, the teacher grounds the students in their investigation plan and reviews science vocabulary that has previously been introduced. You will see students conduct a “fair test” to determine which type of magnet is stronger. Then they will discuss their results and write in their science notebooks using a “claims and evidence” format that the teacher introduces for the first time. As the students proceed through this investigation—observing, gathering and interpreting evidence, and sharing conclusions—the teacher intentionally provides opportunities for students to use language in discussion with their teacher, their partners, their table groups, and in whole-class science talks. In later lessons that follow this record, students will further investigate magnet strength and talk and write about their conclusions, reinforcing the “claims and evidence” format. Students conclude the unit by reading a book on magnets and reviewing what they’ve learned.
These videos are accompanied by interactive annotations highlighting practices that support language development in the context of science. You may choose to pause the videos and read as you go, use the annotations to navigate to different portions of the videos, or view the videos without annotations.
