Blog of the day! What we did today is...

Today (September 27, 2011) we worked on three density gizmos. Plus we found out if some candy bars could float. For example, KitKats float but Hershey bars do not. What the gizmos taught us is that a material, no matter what size it is, will always have the same density. They also taught us that if the density is less than 1 gram/ cm^3 then the object will float. If the density is more than that then it will sink. By the way, density=mass/volume is something we learned a while ago, but I thought I would add that. After the gizmos we had to take assessments that dealt with what was in the gizmo.
