A) Chemicals:
B) Used paper towels:
C)Matches:
Pg.
1-2
3. Identify the independent variable, dependent variable, constants, and control in the following
experiment scenario:
Megan wants to see if playing her favorite music to plants will affect their growth. She buys 20
tomato plants from Wal-Mart. She waters and fertilizes all 20 plants. Megan places 10 plants along a
windowsill in a quiet room. She puts the other 10 plants along a window sill in the next room with
continuously playing music. Both of these rooms are facing south and both are kept at a temperature of
72° Fahrenheit. Every day she equally waters the plants. She also records the growth of every plant.
