The EIE Curriculum

EiE - Solid as a Rock: Replicating an Artifact Lesson 3

Students perform controlled experiments to identify properties of a variety of rocks and humanmade materials.

Reflection Questions

What does Laura do to help her students focus their attention on the physical features of rocks?

Laura uses several different teaching methods to have her students think critically about the properties of rocks and human-made materials.

  • Laura has her students reflect on their observations of the properties of materials out loud. (2:42)
  • Laura presents riddle cards to her students as a way for them to identify the different properties of rocks and human-made materials. (3:22)
  • After Laura has her students conduct a hardness test on the materials, she asks them the purpose of the hardness test.  This kind of questioning allows her students to think systematically about what they are doing during the lesson and to use the knowledge they’re gaining later in the design challenge. (9:03)

How does Laura’s advanced preparation of materials help her keep the lesson flowing smoothly?

Laura demonstrates excellent organizational skills by preparing the materials used for lesson 3 ahead of time.

  • Laura creates her own envelope addressed to her class from the Museum of Science, which further supports her students considering the design challenge in the context of a problem and keeps them involved and engaged. (0:22)
  • Laura has materials for observation pre-prepared on a tray, which saves time during the lesson and provides clarity for her students as they observe the materials they’ll be working with during the design challenge. (2:13)
  • Laura prints out a large version of the hardness test directions for her students to refer to as they conduct their test.  This provides clarity for her students and serves as a reference point as they engage with the materials. (7:50)
