Multiple Choice

Catalina and Will poured the same amount of water from the same sink into two identical glasses. Catalina and Will used a thermometer to determine that the water was at the same temperature. Will wrapped his glass with black paper. Catalina wrapped her glass with white paper. Both students placed their glasses under the same light. The temperatures after 20 minutes are shown below.

  

What might explain the differences in Catalina's and Will’s temperatures?

• Will’s water evaporated, and Catalina’s did not.

• Will used a darker color of paper than Catalina did.

• Will’s starting temperature was different from Catalina’s.

• Will’s water was placed under a light, and Catalina’s water was in the shade.

• circle any words that are misspelled or should be replaced   

• eck the charts or graphs to be sure there are no math mistakes  

• repeat the investigation exactly to see whether they get the same results

• repeat the investigation, but change some things to see whether they get the same results

Multiple Choice

Arion is making a model to show how light travels. In his model, he is using a tennis ball as the light source. He is using string to represent light. How should he use the string to model the way that light travels?

• Tape the string so that it forms a tiny zigzag. 

• he string tight so that it forms straight lines.

• Form the string into an arc to show how light bends.

• Wind the string around a pencil so that it forms a spiral.

Multiple Choice
