MSSD Science teachers Mr Mark Tao and Mr. Jonathan Lamberton study the best way to record ozone damage on Cutleaf Coneflower leaves. The teachers used a special data sheet designed to show each leaf on the plant. Sometimes the leaves were missing, sometimes they were damaged, and sometimes the leaf was healthy. Scientists have learned that many kinds of plants are sensitive to ozone. At MSSD students will study the Cutleaf Coneflower and Bush Beans. |

MSSD Science Teachers Ms. Mary Ellsworth and Ms. Kamilla Jakubowyc count pairs of leaves on a Cutleaf Coneflower plant and record the % damage from ozone. The teachers learned to recognize several kinds of damage. Plant leaves can be damaged by disease, insects, and drought, as well as ozone. Plants that are sensitive to ozone are called 'bio-indicators'. They are living organisms that help determine the health of an environment. |

Mr. Lamberton and Ms. Jakubowyc attend while Dr.Howard Neuman shows how to use equipment to measure ozone. The equipment in the picture costs several hundred dollars. The teachers also learned how to use a simple device called a Zikua that students can use in the classroom which is much less expensive, but very accurate.  A Zikua for measuring ozone. 'Zikua' is a word that means 'to see the invisible" in Swahili. |
