Question

look at the picture. a student does an experiment with four identical plants. each plant gets a different color light. what question can this experiment answer? which colors of light make up daylight? which kind of plant grows best in red light? which color of light is best for growing plants? which different kinds of plants need bright light? 12 multiple choice 2 points miguel was conducting an experiment. he wrote the following sentences in his notebook: the starting temperature of the water was 10 degrees celsius. an object weighing 5 grams was placed in the water. the temperature of the water increased to 15 degrees. the object must have been hotter than 10 degrees. in which sentence did miguel make an inference? sentence 1 sentence 2 sentence 3 sentence 4

Explanation:

• First question:
• The experiment has four identical plants under different - color lights. The variable is the color of light. So, it can answer which color of light is best for growing plants.
• The first option (about daylight composition) is not relevant as the experiment is about plant - growth under different colors, not daylight composition.
• The second option is wrong because all plants are identical.
• The fourth option is wrong as all plants are the same and the variable is light color, not plant type.
• Second question:
• An inference is a conclusion drawn from observations.
• Sentence 1 (starting temperature of water) is an observation.
• Sentence 2 (object's weight and placement) is an observation.
• Sentence 3 (temperature increase) is an observation.
• Sentence 4 (object being hotter) is an inference based on the fact that the water temperature increased.

Answer:

• First question: Which color of light is best for growing plants?
• Second question: sentence 4
