Maria believes that the color of a car may influence how much its interior heats up in the summer sun. To explore this, she conducts an experiment by placing cars of different colors (black, white, red, and silver) outside in direct sunlight during a hot summer day. She records the temperature inside each car after 2 hours. The factors that stay the same throughout the experiment include the time of day, the location of the cars, the type of material in the car interiors, and the duration the cars stay in the sun. What is the independent variable in Maria’s experiment?

• A. The color of the cars

• B. The location of the cars

• C. The temperature outside

• D. The duration the cars stay in the sun

The factors that stay the same throughout the experiment include the time of day, the location of the cars, the type of material in the car interiors, and the duration the cars stay in the sun. What would we call the temperature inside the cars in this experiment?

• The control

• The constant

• The dependent variable

• The independent variable

Answer explanation

independent variable-what you change in the experiment (graphed on X-axis of a graph)

dependent variable-the numerical data collected. It depends on the independent variable (graphed on the Y-axis of a graph).

What is the term for the deep, dark layer of the ocean where sunlight cannot penetrate, and photosynthesis is not possible?

• A. Aphotic

• B. Littoral zone

• C. Photic

• D. Pelagic

Answer explanation

The littoral zone is the shallow, near-shore area of a lake, river, or sea where sunlight reaches the bottom. It's also known as the nearshore or litoral zone

The pelagic zone is the open ocean, which is the part of the ocean that's not near the shore. It's also known as the open sea. 

the "photic zone" refers to the upper layer of water where sunlight penetrates, allowing photosynthesis to occur. the light zone.

the "aphotic zone" is the deeper region below where there is virtually no sunlight, making photosynthesis impossible; the dark zone.
