On Tuesday, January 12, 2016 fifth grade students from Chandlers Elementary were able to experience a hands-on science lab presented by Mrs. Vicki Jo Stephens Valentine.
Mrs. Valentine came to the Chandler’s from the TVA Science Kids program and was able to spend 90 minute blocks with each 5th grade class. During this time, the students were able to perform several experiments with water collected from two different local sites, Lake Malone and a local Chandler’s water source. The students were able test the water quality indicators of temperature, turbidity, pH, and dissolved oxygen. Students worked in teams and conducted experiments using beakers, test tubes, and reacting agents.
The students then recorded and interpreted the data. Mrs. Valentine provoked students’ thoughts by using the scientific method as they conducted the experiments with both of the local water sources. Classes also had the opportunity to enter the data into a global website and look at water quality around the world for a global connection. The students made many real-world connections to the quality of water, as well how wildlife would react to the local water quality. Chandler’s students really seemed to enjoy the hands-on learning that they took part in the TVA Science Kids program.
Ms. Casi Bright, a Chandler’s fifth grade teacher said, “Mrs. Valentine was enthusiastic and engaging; she did an awesome job communicating and making connections with the students. I am so glad our students could take part in this lab experience.”
