TCAP Review Part 5

A teacher does two experiments. In Experiment A, the teacher pours two liquids into one beaker. When the two liquids mix, a dark liquid and a white solid are in the beaker. In Experiment B, the teacher pours two solids into one beaker. The two solids can be seen mixed together in the beaker. Which table correctly uses evidence from the experiments to explain what happens during each experiment?

• A) Experiment A: Mixing the two liquids forms a mixture. Evidence: The two liquids have not changed and can each be seen in the beaker. Experiment B: Mixing the two solids forms new substances. Evidence: The solids in the beaker change shape, and a new solid is formed.

• B) Experiment A: Mixing the two liquids forms new substances. Evidence: The two liquids have not changed and can each be seen in the beaker. Experiment B: Mixing the two solids forms a mixture. Evidence: The solids in the beaker change shape, and a new solid is formed.

• C) Experiment A: Mixing the two liquids forms new substances. Evidence: The liquid in the beaker changes color, and a white solid is formed. Experiment B: Mixing the two solids forms a mixture. Evidence: The solids have not changed and can each be seen in the beaker.

• D) Experiment A: Mixing the two liquids forms a mixture. Evidence: The liquid in the beaker changes color, and a white solid is formed. Experiment B: Mixing the two solids forms new substances. Evidence: The solids have not changed and can each be seen in the beaker.

Why is the final mass recorded by Student 1 different than the final mass recorded by Student 2?

• The final mass of Student 1’s bag is less because the baking soda dissolved more, decreasing its mass.

• The final mass of Student 1’s bag is less because the temperature was higher, releasing mass as energy.

• The final mass of Student 2’s bag is more because the new substance that formed stayed in the bag.

• The final mass of Student 2’s bag is more because more bubbles produced more gas.

In a desert, scientists find two fossils (Y and Z) in two different rock layers. How can scientists determine which fossil is older?

• Fossil Y is older because it is found on top of fossil Z.

• Fossil Y is older because it is found in a lighter color rock.

• Fossil Z is older because it is found in the rock layer below fossil Y.

• Fossil Z is older because it is found in a darker color rock.
