Trickum Middle School 6th grade students are taking a field trip to the Chattanooga river in order to take water samples. Students noticed that their samples taken from three different locations of the river, the rocks were the same, but the minerals within the rocks were different. Which of the following statements best proposes a way for students to plan and carry out an investigation that can determine the type of mineral that contributed to the formation of rocks?

a)

Students can set up various tests to observe the different properties of the mineral because all minerals have the same properties

b)

Students can observe color to identify the mineral because color can easily be used to determine a mineral’s identity.

c)

Students can set up various tests to observe the different properties of the minerals because minerals have different properties.

d)

Students can observe color to identify the mineral because color is one of the properties of minerals.

Students were investigating the growth of crystals using a hot plate and a refrigerator. They wanted to know if the rate of cooling would affect the formation of crystals. Which of the following observations would be correct and help them in sorting the rocks into the correct group?

a)

Smaller crystals formed in the beaker in the refrigerator, where cooling is slower.

b)

Smaller crystals formed in the beaker on the hot plate, where cooling is slower.

c)

Larger crystals formed in the beaker in the refrigerator, where cooling is faster.

d)

Larger crystals formed on the hot plate, where cooling is slower
