The Popsicle Investigation

When making frozen juice pops for a picnic, Dr. Igneous became curious about how long it would take for the juice to freeze. Knowing that juice is a solution of more than one substance, she wondered how the freezing time of juice would compare to the freezing time of water without a juice concentrate added. She assumed that the juice (a solution of two substances) would take longer to freeze than the water alone.

The scientist got five identical paper cups and five identical wooden sticks. She labeled each cup precisely. One cup had pure juice. One had half juice and half water. The third had one fourth juice and three fourths water. The fourth one had one eighth juice and seven eighths water. The last cup was full of water.

All cups were placed in the freezer. Every ten minutes, she checked the pops to see how the freezing was coming along. She kept a careful record of the results.

Which conclusion(s) can be drawn from the first paragraph?
  1. Dr. Igneous already has some guesses about the outcome of her experiment.
  2. Dr. Igneous had done this experiment several times.
  3. Dr. Igneous works in a science lab.
  4. A solution is a combination of more than one substance.
