Elena's Experiment with Plant Growth

Elena, a student from St. Xavier High School, conducted an experiment to explore the effects of magnets on plant growth, using wheatgrass as the test plant. She set up control and experimental groups with different magnet strengths and measured various growth parameters. Her findings revealed that while plants without magnets grew taller, those exposed to stronger magnets were denser and heavier, suggesting increased nutrient uptake. Elena concluded that quality of growth is more important than quantity and proposed separating water sources in future experiments to better understand the impact of magnets on plant growth.

What plant did Elena choose for her experiment and why?

• Spinach, because it grows quickly

• Wheatgrass, due to its health benefits

• Tomato, for its nutritional value

• Lettuce, because it's easy to grow

What was the main issue Elena faced with the initial magnets?

• They were too weak

• They were difficult to handle

• They caused rust

• They were too expensive

How did Elena improve the magnets for her experiment?

• By using magnets with a rubber coating

• By using magnets made of copper

• By using magnets with a plastic coating

• By using larger magnets

What measurements did Elena take during her experiment?

• Height, pH, temperature, and electrical conductivity

• Height, weight, color, and temperature

• pH, weight, color, and electrical conductivity

• Height, weight, pH, and color

What was the unexpected result regarding plant growth?

• Plants with no magnets grew taller

• Plants with magnets had fewer leaves

• Plants with magnets grew taller

• Plants with no magnets grew shorter

What did Elena conclude about the density of plants exposed to magnets?

• They were less dense

• They had more nutrients

• They were lighter

• They had fewer nutrients

What improvement did Elena suggest for future experiments?

• Increasing the experiment duration

• Using different plants

• Separating the water for each group

• Using more magnets

How can Elena's findings help urban farmers?

• By reducing water usage

• By reducing the need for sunlight

• By growing more plants in less space

• By increasing the size of plants

What global issue could Elena's research potentially address?

• Water scarcity

• Deforestation

• Climate change

• Soil erosion

What is the main takeaway from Elena's experiment regarding plant quality?

• Both quality and quantity are equally important

• Quality is more important than quantity

• Neither quality nor quantity matters

• Quantity is more important than quality
