Put Science in Your Announcements! May 20, 1927: Charles Lindbergh takes off from New York in a small airplane, the "Spirit of St. Louis." Thirty-three hours later, he lands in Paris, completing the first solo crossing of the Atlantic Ocean by air. |
| “Inquiring into Chemical & Physical Change” June 20-21st |
Explore chemical and physical change using inquiry-based methodologies and "chemicals" found at home. Participants will solve a mystery, make soda pop, light a light bulb, and better understand chemical and physical change. All experiments are simple, safe and FUN! Leave with a student-led lesson on chemical & physical change your students will love. This is just one of four new teacher workshops this summer at COSI Columbus! See detailed information about all of COSI's new Summer 2007 Teacher Workshops. |

| Transpiration Station |
Now that the spring weather is finally cooperating, plants are actively growing. Take advantage of the warmer temperatures and use the plants around your school to observe and predict a basic plant process: transpiration. Materials:
1. Place one sandwich bag over one leaf of the plant. 2. Secure the bag on the stem with the tape or twist tie. 3. Ensure the bag will be in the sunlight for two or three hours. 4. Fill the second bag with air without blowing into the bag. 5. Secure the bag to the stem the same way you did the first bag. Make sure there is not a leaf inside this bag. 6. Make a data table to record your observations of the two bags. Make observations at least 5 times at half hour intervals. Transpiration is the process of water loss from plants through stomata. Stomata are small openings, or pores, found on the underside of leaves that are connected to vascular plant tissues. In most plants, transpiration is a passive process largely controlled by the humidity of the atmosphere and the moisture content of the soil. Of the transpired water passing through a plant, only 1% is used in the growth process. Transpiration also transports nutrients from the soil into the roots and carries them to the various cells of the plant and is used to keep tissues from becoming overheated. Some dry environment plants do have the ability to open and close their stomata. This adaptation is necessary to limit the loss of water from plant tissues. Without this adaptation these plants would not be able to survive under conditions of severe drought. Some trees lose as much as 15,000 pounds (6,810 kg) of water within a 12 hour period!
