Oskar went into the grocery store in June (2011) and saw a shelf piled high with boxes of candy canes that are on sale. Oskar thinks that this is strange and assumes that they are left over from last winter. He grabs one of the boxes and examines it for a sell by date. The date on the box is 11/2011.
What is Oskarβs Hypothesis?

Oskar thinks that this is strange and assumes that they are left over from last winter. He grabs one of the boxes and examines it for a sell by date. The date on the box is 11/2011.
What is Oskarβs Hypothesis?The candy canes are left over from last year and outdated
Oskarβs hypothesis was refuted (not supported) by the date on the boxes.
The observation of this property of matter is always accompanied by a change in the composition of matter?
Physical or Chemical
9
The observation of this property of matter is always accompanied by a change in the composition of matter?
Physical or Chemical The composition of matter does not change in a physical change.
What type of change is represented by the freezing of water to form ice?
Physical or Chemical
10
What type of change is represented by the freezing of water to form ice?
Physical or ChemicalWhen water freezes there is no change in the composition (what it is made of). Liquid water and ice are both made of H20.
