A group of students was conducting an investigation with plants. One group of plants was placed inside a closet. The other group of plants was placed next to a window. After 2 weeks, the plants next to the window were taller and healthier than the plants in the closet. Which statement BEST explains the difference in plant growth?

• The plants next to the window were able to convert more thermal energy into light energy.

• The plants next to the window were able to convert more thermal energy into mechanical energy.

• The plants next to the window were able to convert more light energy into electrical energy.

• The plants next to the window were able to convert more light energy into chemical energy.

Students model waves using a parachute. When they place balls in the center of the parachute, they rise into the air. How would the motion of the balls change if the energy of the parachute waves increased?

• The balls would stay on the parachute and sit in the center.

• The balls would rise into the air but not go as high.

• The balls would rise into the air and go higher than it originally did.

• The balls would stay on the parachute but sit on the edge.
