Rainbow Measurement
 
Big Idea: Students are scientists who collect quantitative and qualitative data, keep accurate records and evaluate possible causes for differing results.
  Favorites (11)   Resources (11)   Reflections (1)
Liquid Tower Density
 
Big Idea: We will explore an important concept of density - how space between atoms decreases when density increases.
  Favorites (12)   Resources (13)   Reflections (1)
Float, Suspend, Sink
 
Big Idea: The size of the object, or volume, is only one part of the density equation. Changing mass alone can change the density.
  Favorites (9)   Resources (12)
Density of Water
 
Big Idea: Understanding that a centimeter cube will displace one milliliter of water builds the foundation to understand how the volume of an object can be determined by the displacement of water.
Standards:
  Favorites (3)   Resources (15)   Reflections (1)
Raisins and Popcorn Kernels
 
Big Idea: The weight of the object, or mass, is only one part of the density equation. Changing volume can change the density.

Density of Irregular Objects Day 1: Developing Procedures
 
Big Idea: Apply what we have learned so far about density, mass, volume and displacement to create and communicate instructions for a new lab.
  Favorites (5)   Resources (17)   Reflections (2)
Density of Irregular Objects Day 2: Communicating our Procedures
 
Big Idea: Scientists are writers too. Scientists communicate to one another scientific and/or technical information (e.g. about a proposed object, tool, process, system) in writing and/or through oral presentations.
