Investigation on Affect of Invasive Species on an Ecosystem
My students need microscopes that are high quality in order to see the population of yeast grow in their experiment. They need yeast, sugar, string, iodine solution test tubes and microscope slides to complete their investigations
My scholars are so special because they strive to excel not only academically, but in all that they put their minds to everyday. The scholars at my school in Kansas City, Missouri are primarily from a low-income neighborhood; however, they've made up their minds not to let anything stop them from accomplishing their dreams and aspirations. They have a longer school day (7:45 am - 4:30 pm) because they know how fundamental their learning is and how crucial it is to maximize learning time for success. The scholars have outperformed their peers time and time again. Their recent test scores on end of the year exams and MAP have exceeded their peers in Kansas City and in the state of Missouri. We're so proud of the work our scholars are doing!
These materials will not only provide staple tools in our science department, but they will help students as they design their own investigation to see how ecosystems are interconnected and dependent on other living and non-living organisms. In the second investigation of the unit, scholars are introduced to the concept of population growth and some of the factors that can affect the size of a population. Specifically, this investigation gives scholars an opportunity to explore how the size of a population of yeast changes in an experiment that involves control conditions and the manipulation of one variable.
The test tubes, microscopes and slides will allow students to see exactly how limiting factors such as food (sugar) or other environmental factors (iodine solution) can impact the growth of yeast.
This same concept is applied in general to all ecosystems and through data analysis and research of their results, scholars will be able to make that connection and apply it to design solutions for protecting ecosystems.
