Physical Science SSA Review

During science class, while studying mixtures, you mix together table salt and sand. Your teacher challenges you to separate the salt from the sand. What property could you use and how would you use it?

• Solubility; add water to the mixture and dissolve the salt 

• Density; the two will form two layers.  Scoop out the top layer 

• Color; pick out one of the two solids by using color to guide you 

• Particle size; pour the mixture through a paper filter to separate the two 

Matthew has all kinds of time on his hands so he gets more cubes and sorts them again.  What might be the basis of his classification?

During Mr. Nye's science class, students were expected to identify various substances using physical properties they could easily measure. Mr. Nye gave each of the five groups a green, metal cube. The students had to identify what metal the cube was made of. The length of each side was 3.0 cm and the mass was 270 grams. What property should Mr. Nye’s science students use to identify the metal in the cube? 

• Density

• Color

• Mass

• Volume

Students observe properties of the materials listed below.  They notice that the items on their list that are more thermally conductive are also more electrically conductive. Based on this information, which objects could they use to connect a battery to a light bulb to make it turn on? 

• Glass, rubber, and iron

• plastic and copper

• iron, aluminum, and copper

• aluminum and rubber
