Second hand smoke.

The purpose of this experiment was to see if radishes would grow better watered with vitamin C while being exposed to second hand smoke. A terrarium was used to grow the radishes. The radishes were exposed to second hand smoke daily for 32 days and to direct cigarette smoke twice a day for 5 minutes for 32 days. At the end of the experiment, she measured the leaf surface area. The final height for the radishes watered with vitamin C was 13cm. The final average height for the control group of radishes was 9.7cm, which is a difference of 3.3cm. The leaf surface area for the plants watered with vitamin C was 0.00043 [m.sup.2] . The Leaf surface area for the plants watered with plain water was 0.00042M2. The difference between the two was 0.00001 [m.sup.2], which is a difference of 2.4%. Further tests are being conducted.
