Question 6

Hannah conducts an investigation to determine if adding fertilizer to the soil helps tomato plants grow taller. She puts 20 tomato plants in individual pots and adds an equal amount of soil to each pot. All 20 plants are the same height at the beginning of the investigation. She adds the same amount of fertilizer to the soil of 10 pots. Hannah measures the height of each plant once a day for 15 days.

Revolt · Accepted Answer

The presence of fertilizer in the soil is the .: independent variable; The height of the tomato plants is the .: dependent variable; The pots without fertilizer are the .: control group

✔ collecting data; Kiran records the height of each plant―those with a colored filter and those without.: collecting data; Kiran explores the growth of a plant in natural light, then repeats the experiment with the same plant type but different colored filters.: performing an investigation; Kiran turns in a written lab report to her science teacher.: communicating results; Kiran wonders, “Will colored light affect the growth of a plant?”: asking a question; Kiran writes in her notes that adding a colored filter over a plant affects its growth because the heights of the plants under the colored filters were less than the height of the plant with no filter: providing explanations

Question 8

In a laboratory, Carlos places one plate with grape jelly and another plate with cooked brown rice inside an ant farm. The next day, he finds that both plates are filled with ants. Carlos wonders if there are certain household foods that are more effective than others at attracting ants. How could Carlos use the scientific inquiry process to determine which foods are most effective at attracting ants? Check all that apply.by making quantitative observations about the number of ants found on each plate of foodby asking a classmate if ants are attracted to bananasby comparing a plate of cooked brown rice to another household food such as peanut butterby designing an experiment to test different foods and the number of ants each food attractsby repeating the experiment at different times of day
