Importance of Trait Variations in Desert Beetles

Exploring the significance of trait variations among desert beetles, this lesson delves into why variations matter and how they impact survival in the desert environment. Through activities and discussions, students analyze traits, predict beetle survival, and understand the implications of variations in traits. The focus question stimulates critical thinking about the role of trait variations in the survival of desert beetles in their natural habitat.

1. VARIATION IN TRAITS LESSON 3A Why Do Trait Variations among Desert Beetles Matter?

4. Beetles in the Desert While you re reading the story Beetles in the Desert, think about these questions: What living thing is this story about? What are some of its traits? Is there variation in the traits?

5. The Desert Model The model represents what might happen to the beetles in nature. Each colored pom-pom represents a beetle . Pinching my index finger and my thumb together represents a lizard eating a beetle. The fabric represents the desert environment where the beetles and lizards live. Photo courtesy of Cal Poly Pomona

6. What Will Happen to the Beetles? Do you think some beetles will survive longer than other beetles in our desert environment? Photo used with permission from BSCS List one or two reasons why you think a particular beetle might or might not survive longer than other beetles.

7. Share Your Predictions Share your predictions and reasons using this sentence starter: I predict that some beetles [will/won t] survive longer than others in our desert environment because _______________. Share comments using these sentence starters: I agree/disagree with your idea because I want to add I have a question about

8. Our Focus Question Why do trait variations among desert beetles matter?

9. Lets Summarize! Look at the prediction and reasons you recorded earlier in your notebook for this question: Do you think some beetles will survive longer than other beetles in our desert environment? If your prediction has changed based on the ideas we shared in our class discussion, revise it. You can change or add to your original prediction. Or you can write a new prediction and reasons to support it.

10. Next Time Next time, we ll use our desert model to test our predictions about whether some beetles will survive longer than others in their environment. Do you think variation in traits among beetles has anything to do with their survival? Stay tuned!
