Question

using only these supplies, which
question can denise investigate with an
experiment?

when placed in the
sun, will eight ounces
of water in a glass jar
or eight ounces of
water in a plastic cup
get warmer?

when placed in the
sun, will eight ounces
of water in a closed jar
or eight ounces of
water in an open jar
get warmer?

will eight ounces of
carbonated water or
eight ounces of tap
water get warmer
when placed in a jar in

Explanation:

To determine which question Denise can investigate, we analyze each option:

Option 1 (Glass jar vs. plastic cup):

This compares water in different containers (glass jar vs. plastic cup) with the same volume (8 ounces) in the sun. To test this, Denise can use a glass jar, a plastic cup, and 8 ounces of water for each—all supplies that are likely available (or can be assumed to be part of "these supplies" if the setup involves basic containers and water). She can measure temperature change to see which gets warmer.

Option 2 (Closed jar vs. open jar):

Testing this would require controlling evaporation (open jar allows evaporation, closed does not). However, evaporation itself can affect temperature (e.g., evaporative cooling), and the question is about "getting warmer"—but the key issue is whether "closed" vs. "open" jars are part of the supplied materials. If the supplies do not include both closed and open jars (or a way to seal a jar), this is harder to test. Additionally, the first option focuses on container material (glass vs. plastic), which is more straightforward with basic supplies.

Option 3 (Carbonated vs. tap water):

This requires carbonated water, which may not be part of the "supplies" (tap water is common, but carbonated water is a specific type that might not be included). Thus, it is less likely to be testable with standard supplies.

Among the options, the first question (comparing glass jar and plastic cup) is the most feasible to investigate with basic supplies (water, glass jar, plastic cup, sun, and a thermometer to measure temperature).

Answer:

When placed in the sun, will eight ounces of water in a glass jar or eight ounces of water in a plastic cup get warmer?
