Nicholas planted five carrot seeds in each of three different milk
cartons of equal size. He filled each carton to the same level with the
same kind of soil. He put on carton outside in the sun, one on the
counter in the classroom light, and one inside a dark closet. He gave
each carton 25 ml of water each day at 11 am. He watered all three
cartons every day for fifteen days and then measured how tall each
plant grew.

chips all about the same size. She then crushed them each on a

measure the widest part of the grease stain for each chip and
compared the results to see which was the greasiest.

hole in the bottom of each cup. He filled each cup to the same
level with different material - soil, sand, or pebbles. Then he
poured 1 cup of water into each cup at a time and held it over
the tray for one minute. He then measured the amount of water
that drained into the tray from each cup.
