A second-grade teacher is about to start a unit on the physical properties of objects and substances. What is the best initial strategy to foster students’ active engagement?

• A. give five minutes to write names of hard or soft objects they can think of
• B. involve the students in a discussion of physical properties that are familiar and meaningful to them
• C. write on the board a list of properties such as color or texture and provide examples
• D. have students complete a matching exercise connecting pictures to property words

Answer: (B)

The main idea being tested is how to kick off a science unit in a way that actively engages students by connecting the content to their own experiences. Involving second graders in a discussion about physical properties that are familiar and meaningful to them taps into their prior knowledge, sparks curiosity, and invites language use as they describe objects they know. This sets a collaborative, inquiry-based tone for the unit and helps students see science as something relevant to their daily lives. For example, you might ask students to talk about things around the room and describe how they feel—hard or soft, smooth or rough, heavy or light—then capture their ideas on a class chart. This approach supports participation from all learners, including those who are English learners or who benefit from concrete, real-life references, and it provides a foundation for more formal observations of properties later on. Other options can still be useful later, but they don’t invite the same level of student voice and personal relevance at the outset. Writing a quick list of object properties, or a board-and-examples activity, or a matching exercise tends to be more teacher-directed or structured, which can limit initial curiosity and discussion that builds engagement.
