There are many science projects kids can perform using freshly cut flowers. They can set the flowers in a glass of dyed water to observe the water as it travels up the stem of the flower. If your child has to work with cut flowers for science class, you will want to preserve the flower for as long as possible. This can be done by adding a few simple ingredients to the water.
Pour warm water into a glass.
Add the 7-Up and chlorine bleach to the cup. These ingredients stop bacteria growth, which causes the cut flowers to die prematurely.
Choose a flower to work with, and cut it with a pair of gardening scissors. If you bought the cut flower, you will need to cut it just before you place it in the water. Cut 1/2 to 1 inch off the bottom, at an angle.
Place the cut flower in the warm water as soon as it is cut.
Begin your experiment.
