________ are controlled variables, kept the same throughout the different groups. They make the results more reliable because then the only difference between experimental and control groups is the independent variable.
A ______ group makes an experiment more accurate because it is used as a standard for comparison, which allows us to know what is considered “normal”.

Ada and Elijah have decided to do an experiment testing how sunlight affects plant growth. The students choose the same type of plants, soil, pots and amount of water they give the plants. They also make sure each plant is put in their designated area for the same amount of time each day. One plant is placed outside; one in front of a window that only gets light for 1/2 the day, and one in a closet. The students collect data every day for two weeks. Their results show that the plant outside grew the most and the plant in the closet had the least amount of growth.
What are the constant variables that Ada and Elijah used in their experiment?
What are "Type of environment and type of soil"

Five students each used the same ruler to measure the length of the same pencil. Their measurements were: 15.33 cm, 15.34 cm, 15.33 cm, 15.33 cm, 15.34 cm. The actual length of the pencil was 15.85 cm. Explain whether the students’ measurements were accurate, precise, both, or neither.
