Gravity, Plants, and Matter

Brian gives his mother two marigold plants of the same size in the spring. She puts one in a shady spot and one in a sunny spot. Both plants get equal amounts of water and fertilizer. Both plants grow, but by the end of the summer, the plant in the sunny spot is twice as large as the plant in the shade. Why was the plant in the sunny spot taller than the plant in the shade at the end of the summer?

• This plant received less energy from sunlight.

• This plant was fertilized more often.

• This plant received more energy from sunlight.

• This plant was watered more often.

Julia had three plants, each the same type, size, and age. She gave all three plants the same amount of water and sunlight. She put one of the plants in a clear Ziploc bag and sealed it shut. After a few days, plant C began to show signs that it was dying. What most likely caused plant C to begin to die?

• Plant C could not get sunlight.

• Plant C could not get fresh air.

• Plant C did not have enough water.

• Plant C did not have enough fertilizer.

Janice found two seashells when she went to the beach. They appear to be almost the same size, but they have different shapes. When she holds them in her hands, they seem to have about the same weight. She wants to find out how similar they really are. How could she figure out if their volume is the same?

• Weigh each one on a scale to see which is heaviest.

• Fill each one with water to see which will hold the most.

• Drop each one in a beaker of water to see, which raises the water level the most.

• Measure the length of each one with a measuring tape to see which is the longest.
