- Student Instructions For each assignment, you will use the M.U.S.E. link to complete the lab. Access the M.U.S.E. by clicking on Learning Materials. https://class.aiu-online.com/_layouts/MUSEViewer/MUSE.aspx?mid=3319400 In this lab, you will determine how an invasive species—the zebra and quagga mussel—affects other species in the freshwater lake. Use the animation to help you come up with an answer to the following: Why do you see increases and decreases in the invasive species population? What are the implications associated with these alterations to the ecosystem as a whole? The Effects of Zebra and Quagga Mussels Introduced into a Freshwater Lake As you have learned, population dynamics are caused by the biotic potential of the population and the effects of environmental resistance. When there is minimal environmental resistance impacting a population, it will exhibit a population explosion. One reason for minimal resistance could be factors that no longer regulate a population (e.g., predator decline or resource increases). Another reason for a population explosion is the introduction of an invasive species. Invasive species are species foreign to an ecosystem and are not immediately regulated by the environmental restraints of the particular ecosystem that they invade. This in turn allows their populations to grow seemingly uncontrolled and to displace other indigenous populations. Examples of such an invasive species into North America are dreissenid mussels, commonly known as zebra and quagga mussels. Their introduction into the Great Lakes has caused economic hardship and a reorganization of the ecosystem. This has led, in part, to pollution-causing effects that can be linked to an alga known as Cladophora. Ecosystems are webs of intricately balanced interactions, what happens when a new species is introduced that uses a disproportionate share of the ecosystem’s resources? Using the M.U.S.E. link, review the background information and animation to complete your report. Use the Lab 5 worksheet for assignment instructions and data collection.

- In Week One of this course, you were asked to find a child to observe. For this assignment, you will observe the child using the requirements below and summarize your observation. This can be done in one sitting, or it can be done in two since you will be conducting two different observations. Two is preferable for accuracy of assessment. For the observation you will need to: Be sure you have the permission of the child’s parent. Exclude any identifying information for this child (e.g., last name) Follow the guidelines on pages 141-144 of the course text regarding behaviors during the visit (ethical conduct, avoiding personal bias, etc.). Be sure you have the appropriate materials ready: You will need either a Running Record Form or an Anectodal Record Form, whichever you choose. For this form, you will choose one developmental domain to observe (e.g., cognitive, physical, motor, or language). You will need either a Time Sampling Form or an Event Sampling Form, whichever you choose. For this form, you will choose one developmental domain to observe (e.g., cognitive, physical, motor, or language). Example: Assessing “Bobby,” I would first observe his motor development using an anecdotal record form. In a different sitting, I would observe his cognitive development using an event sampling form. For the assignment, you will need to include: A title page. A copy of the completed Running Record Form or Anecdotal Record Form (remember this should address one domain). A copy of the completed Time-Sampling Form or Event Sampling Form (this should address a different domain). A one page summary of the observation(s). In this summary, include: How you felt the observation went and why. How receptive you feel the child was and why you feel that way (if using one of the video options state the reaction of the child upon being videotaped as you see it). The most challenging aspect of this observation. The most enjoyable aspect of this observation. What you learned from this experience. What you would change next time. A one-page paper providing some developmentally appropriate activities you might implement for this child in the classroom or daycare center to foster growth in each of the developmental domains you observed, and why those activities are a good fit for this child. Your two-page paper should be in proper 6th edition APA format. Remember to submit two written pages, both observation forms, and your title page in one document. Carefully review the Grading Rubric for the criteria that will be used to evaluate your assignment.
