2. Lay one white daisy horizontal on the cutting board with the flower side on the left. With a ruler measure 8 inches of the stem from the flower. Cut the stem at the 8 inches mark at an angle Not a flat cut, this will increase the amount of water the flower can take in. Record the length of stem in the chart.

3. Repeat step 1 with the remaining two white daisies.

4. Take one clear glass. Fill the measuring cup with 2 cups of water. Empty the measuring cup into the glass. Record the amount of water measured in the chart.

5. Take the blue food coloring and add 25 drops into the water. Pick the glass up and swirl softly to allow the color to fully mix with the water.

6. Repeat step 4 with a new clear glass. Take the red food coloring and add 25 drops into the water. Pick the glass up and swirl softly to allow the color to fully mix with the water.
