With a partner, obtain two red solo cups.
Write your name(s) and hour on each cup in permanent marker
Label one cup “fertilizer”
Label the second cup “no fertilizer”
Poke five holes in the bottom of each cup (make sure your holes are the same)
Fill each cup with soil to just under the 3rd line in the cup ( Make sure the amount of soil is the same in both)
Use your finger to create a wide 1-2 inch deep hole in the soil of each cup. (Make sure the holes are equal in each cup)
Place two seeds in each cup in the hole you made ( put them next to each other, as far as you can, not on top).
Gently cover seed with soil
Measure 75 mL of fertilizer water in a graduated cylinder
SLOWLY and GENTLY add the fertilizer water to the corresponding cup
Measure 75 mL of water from the sink
SLOWLY and GENTLY add the water to the corresponding cup
Place both cups back on your class tray and return to your seat.
