In this activity, students will apply their understanding that animals have traits inherited from parents, but variation of these traits exists.
In part 1, students will roll dice to see what trait their ‘parent’ robot has. Students will circle the trait after each roll, then have an opportunity to draw their parent robot with the correct traits.
In part 2, students will apply their understanding that variation of these traits exists in a group of similar organisms because organisms inherit a variety of traits from either parent. Students will pair up with a partner, and look at the data tables and picture of the parent robot. Without consulting each other, students must pick an assortment of traits from either parent to create the offspring robot (make sure they don’t do this step together or you won’t see a variety in the offspring!) After deciding upon the traits of the offspring, and drawing their picture, students can compare their picture to their partners. They should notice that the may have some traits in common, but also have differences. Students can use the data and the pictures to answer the two questions about inheritance and variation of traits.
3-LS3-1. Analyze and interpret data to provide evidence that plants and animals have traits inherited from parents and that variation of these traits exists in a group of similar organisms. [Clarification Statement: Patterns are the similarities and differences in traits shared between offspring and their parents, or among siblings. Emphasis is on organisms other than humans.] [Assessment Boundary: Assessment does not include genetic mechanisms of inheritance and prediction of traits. Assessment is limited to non-human examples.]
