Mr. Haselden’s physics students, Dani Weeks and Elias Kief, are busy converting periods to frequencies using wavelengths and time. In their lab, Qualitative Vibrations and Waves, they set up different pendulum lengths. After their calculations, they moved on to measuring and observing longitudinal and transverse waves using a modified slinky. They witnessed constructive and destructive interference firsthand. Out of the book and into the lab!
To begin the chapter on ecosystems, Mr. Haselden’s Biology I class went to the science lab to complete the pond water experiment. They acquired the pond water from down the street and examined it under a microscope. Students were able to identify the amoeba, volvox and spirogyra.
The spirogyra was thrashing around violently under the slide while the Volvox remained still, except for some moving cilia. The lab was both fun and educational. It reminded the group that biodiversity comes in many forms, including the ones we cannot see with the naked eye.
The K8 Pace class enjoyed the visuals of a flame spectroscopy experiment put on by Mr. Baldrich. Flame spectroscopy is a method to chemically analyze the light from a flame to determine what elements are in the sample. The students really enjoyed the pink (Lithium Chloride) and green (Boric Acid) fire, but every color of the rainbow was represented from red (Strontium Nitrate) to purple (Potassium Chloride). Part of our learning objective was to visually observe the different lights produced by elements. The students came up with a hypothesis as to what color each fire element would make. Next, the experiment was conducted and the results taken down. This was also our first time enjoying Eaton Academy’s science lab.
Ms. Lindsey-Kerce’s science classes are studying the tools of science (measurement and accuracy), discovering evidence for the origins of the universe (electroscope lab), and exploring the properties of life(extracting DNA).
Mrs. Romero’s fourth grade science class looked at the skin of an onion under a microscope. They were learning about cells and had to draw what they saw under the microscope.
