Traits, Characteristics & Inheritances

LTLT:  I can develop, communicate, and justify an evidence-based explanation for the evolution of organisms and environments by analyzing and interpreting data from the fossil record. LT: I can describe why some traits are passed on to the next generation Criteria for Success: I can create a shared trait tree with my classmates I can define inherited and acquired traits. Agenda: Warm up Power Point Notes Shared Traits Tree Thinking Questions Exit Ticket Warm up: 1. Do you look like or act like your parents? 2. What’s the same about you? 3. What’s different? LT’s  & CS This week is focused on survival and reproduction. Our LTLT#3 is about adaptation, and we’re going to talk about how adaptations are related to survival Hand out POL arrow Power Point Notes Thinking Questions Shared traits Tree Exit ticket 1.In your own words, describe what traits are. 2.What is an example of an organism, and a trait that is has?   Traits Note Taking Guide LT: I can describe why some traits are passed on to the next generation.

Why? _________________________________________________________________________________________________ _________________________________________________________________________________________________ _________________________________________________________________________________________________ _________________________________________________________________________________________________ _________________________________________________________________________________________________ _________________________________________________________________________________________________ 3) Why are some inherited traits passed on to the next generation and others are not? _________________________________________________________________________________________________ _________________________________________________________________________________________________ _________________________________________________________________________________________________ _________________________________________________________________________________________________ _________________________________________________________________________________________________ 4) Predict what would happen to populations that lived there if a habitat changed dramatically.   _________________________________________________________________________________________________ _________________________________________________________________________________________________ _________________________________________________________________________________________________ _________________________________________________________________________________________________ _________________________________________________________________________________________________   Name ___________________________________________ Class Period: ______________ Date _________________ LT: I can identify inherited human traits and describe traits in other organisms. When organisms reproduce, traits are passed from parents to offspring. A trait is simply a characteristic that is inherited from parents through DNA. DNA is like a blueprint for the cells in an organism, instructing them on how to put together materials that make certain traits. This passing of traits from DNA is called heredity. Directions: As Ms Mac shows you pictures of inherited traits, put a check or an X in the boxes for traits you have inherited from your parents (HINT: These are traits that you have).

Write them down below. 2. COLLABORATE: Now, with a partner or individually, you will construct a Shared Trait Tree that shows the traits that you both share. You will need to talk to your pair about the traits you have inherited and then find out about theirs. You can also talk about other traits that we haven’t mentioned that you might share. You will share this with the class 3. INDEPENDENT: Can you think of another organism (plant or animal) in the Rocky Mountain forests that has certain traits that make it successful in surviving here? Write down the animal and the traits that you think make it successful here.
