You have formulated a hypothesis: "Mangos contain more vitamin C than oranges." To test your hypothesis you measure vitamin C levels in 20 oranges and 20 mangos from trees that were grown in the same orchard under the same environmental conditions (temperature, rain, sunlight). What is the independent variable in this experiment? The amount of rain and sunlight the trees received Vitamin C levels The type of fruit The type of soil the trees grew in

Erin hypothesizes that a certain fertilizer will cause her sunflowers to grow better. She plants 12 plants chooses the first 6 that sprout to treat with the fertilizer. She measures all the plants daily, and notices that the treated plants were an average of 2 cm taller at 6 weeks. She concludes that the fertilizer causes the plants to grow faster. Which fact would lead you to question Erin’s conclusion? The first plant to sprout was treated with the fertilizer. Erin treated the first 6 plants that sprouted. The treated plants were an average of 2 cm taller at 6 weeks. Erin’s friends also conducted the same experiment.
