Plant Growth Experiment: Observing Needs and Conditions

The video tutorial explores the essential needs of plants for growth through an experiment using mung bean seeds. It outlines the materials required, preparation steps, and setup instructions for the experiment. The video then observes the growth of plants under different conditions over several days. Finally, it poses questions to encourage critical thinking about the results and summarizes the key needs of plants, including air, sunlight, water, and nutrients.

What materials are required for the plant growth experiment?

• Wooden boxes, wheat seeds, soil, and fertilizer

• Metal pots, rice seeds, water, and pebbles

• Glass jars, sunflower seeds, soil, and sand

• Plastic cups, mung bean seeds, water, and cotton

What is the first step in preparing the mung bean seeds for the experiment?

• Plant them directly in the soil

• Place them in the sun for a day

• Soak them in a bowl of water overnight

• Freeze them for 24 hours

Where should cup A be placed during the experiment?

• Inside the house, watered every day

• Outside, watered every day

• Outside, not watered

• Inside the house, not watered

What was observed about the plants in cup B?

• They were thriving and green

• They were growing rapidly

• They were overwatered

• They were dry

Why might the plants in cup C be light green in color?

• They lacked sufficient water

• They received too much sunlight

• They were not getting enough sunlight

• They were over-fertilized

What are the essential needs of plants to grow?

• Darkness, air, water, and sand

• Heat, soil, water, and nutrients

• Shade, soil, water, and fertilizer

• Air, sunlight, space, water, and nutrients

What question should you consider about cup A?

• What is its soil composition?

• Why is it overwatered?

• What can you say about its growth?

• Why is it not growing?
