Understanding Experimental Questions in Science

What is the relationship between the distance of a lamp from a plant and the number of bubbles produced?

• The smaller the distance, the more bubbles are produced.

• The smaller the distance, the fewer bubbles are produced.

• The distance does not affect the number of bubbles produced.

• The greater the distance, the more bubbles are produced.

What does the distance between the lamp and the plant represent in the experiment?

• The size of the plant

• The number of bubbles

• The intensity of light

• The rate of photosynthesis

What is the accurate aim of the experiment discussed in the video?

• To find out if the distance affects the number of bubbles

• To measure the temperature change with light intensity

• To determine if light intensity affects photosynthesis rate

• To see if the plant grows faster with more light

What should be removed to create a control setup in the experiment?

• The plant

• The flask

• The light source

• The test tube

What is the purpose of the control setup in the experiment?

• To confirm that temperature affects bubble production

• To show that plants need water

• To demonstrate that bubbles are produced without light

• To prove that light intensity affects photosynthesis
