Unit 4B, Properties of Matter Unit Project: Solving Matter Mysteries Create displays of "Matter Mysteries" for a classroom science museum. Then challenge other students and visitors to solve the mysteries.   Project Link 1 (Chapter 1, page B11) Use objects of varying shape, size, and weight for your display. Pose questions about the objects. Have the questions require measurement and comparison by size, mass, or volume.

What Was It? ¿más o menos? ¿Adivina qué sera? Project Link 2 (Chapter 2, page B27) With other students, brainstorm a list of materials that can be presented in a form or state different from that in which they are normally found. Prepare a display of at least three of these materials in their unusual state or form. You can use pictures or the actual materials. Make signs inviting visitors to identify the materials or to describe how they differ from the material's original form or state.

Using disappearing ink, on index cards write the answers to the questions you posed in your display. When everyone is ready to learn the answers, ask your teacher to make the answers visible.
