    1 1 Gizmos Name: Jana Dari Omari Date: Sept, 27. 2023 Student Exploration: Dichotomous Keys Directions: Follow the instructions to go through the simulation. Respond to the questions and prompts in the orange boxes. Vocabulary: dichotomous key, genus organism, scientific name, species, traits Prior Knowledge Question (Do this BEFORE using the Gizmo.) Jerome is walking through a park when he sees the spider shoivn at left. How could Jerome find out what type of spider it is? The amount of legs spotting, size Gizmo Warm-up In the field, scientists often have to identify an unfamiliar organism (living thing j. A reliable way to identify organisms is to use a dichotomous key A dichotomous key is a series of pained statements or questions th al lead I o the ide ntificalion of an organism. The Dichotomous Keys Gizmo allows you to use five different dichotomous keys to identify a variety of organisms. To begin, make sure California Albatrosses and Organism A are selected. 1. Read the two statements al lower right. Which of lhe two statements most closely matches the characteristics of the bird pictured? Large areas of lhe bird s body are covered in while feathers 2. Select that statement and click Next Continue until you have correctly identified the albatross. If you change your mind about a choice, you can click the Back button. If you incorrectly identify the albatross, you can click the Start Over button and try again. A. Whal is the name of lhe albatross? S h orl-lai led albatross B The scientific name is shown in italics. Scientific names have two parts: lhe genus name and lhe species name. Whal is the scientific name of this albatross?

    Get the Gizmo ready: Activity A: Use a dichotomous key * Make sure lhe California Albatrosses key is selected. * Select Organism B Introduction: As you saw on the previous page, a dichotomous key can help you identify an organism using its characteristics, or traits. The keys in this Gizmo use only physical Iraits. such as fealher color, to identify organisms. In some cases, behavioral Iraits are used in dichotomous keys. For example, some frog species can be identified by their croaks. Goal: Use a dichotomous key to identify albatross species found in California. 1. Compare Take a close look at organism B. A. How does organism B differ from organism A? Large areas of the bird are covered in grey and black fealhers B. Whal physical Iraits do you think can be used to help identify organism B? Colour of beak, fealhers. and feel 2. Identify: Use lhe Gizmo Io identify organism B Then, identify lhe other albatrosses included in lhe California Albatrosses key. Complete the table below. California Albatrosses Organism Common name Scientific name A Short-tailed albatross Phoebastria albatrus B Lighl-mantled albatross Pfioebetria paipebrata C Shy albatross Thalassarcbe cauta D Wandering albatross Diomedea exulans E Laysan albatross Pboebastria immutabitis F Black-footed albatross Phoebastria nigripes 3. Think and discuss: What do you think are some limitations of dicholomous keys? Time-consuming and difficult to use; hard Io navigate and work around Difficult wording; characteristics are explained in a difficult way using unknown words that are hard Io utilize for conclusions Reproduction for educational use only.
