Information
Description
What It Is:
This is a cladogram worksheet. The worksheet contains two cladogram activities. The first activity involves classifying different modes of transportation (bicycle, car, motorcycle, airplane, and on foot) based on characteristics like wheels, motor, wings, and passenger enclosure. The second cladogram activity involves classifying animals (human, snake, monkey, mouse) based on traits like hair, legs, thumbs, and eyes. There are also questions that require analyzing the provided and student-created cladograms.
Grade Level Suitability:
This worksheet is suitable for grades 6-9, potentially extending to early high school biology. The concepts of cladograms and classification are typically introduced in middle school science and reinforced in high school biology courses. The activities require critical thinking and analysis, appropriate for these grade levels.
Why Use It:
This worksheet helps students understand evolutionary relationships and classification using cladograms. It reinforces the concept of shared characteristics and derived traits. Students develop critical thinking skills by analyzing and creating cladograms based on provided and chosen characteristics. It provides hands-on practice in constructing and interpreting phylogenetic trees.
How to Use It:
Students should first read the provided text (pages 524-528) for background information on cladograms. They should then complete the transportation cladogram by filling in the blanks with the correct modes of transport. Next, they should answer the analysis questions about the transportation cladogram. Following this, students should fill in the table indicating which animals have each trait. Finally, they should create their own cladogram for the animals, labeling each branch with the proper characteristic.
Target Users:
The target users are middle school and early high school science students studying classification, evolution, and cladograms. It is also useful for teachers looking for engaging activities to teach these concepts. Homeschooling parents can also use this worksheet to supplement their science curriculum.
