Inherited Traits

TEKS Objective

The student is expected to differentiate between inherited traits of plants and animals such as spines on a cactus or shape of a beak and learned behaviors such as an animal learning tricks or a child riding a bicycle.


Essential Understanding

The student knows that organisms undergo similar life processes and have structures that help them survive within their environments.

Science Background

It’s All About Birds: Museum of Science (PDF) - Illustrations of different beaks, feet and body shapes help to explain the inherited traits of birds. Can be used for background information or as a class activity.

It’s All About Birds
Museum of Science, www.mos.org

Cactus Spines: School of Biological Sciences at The University of Texas, Austin (website) - Use photos and text to explore many varieties of cactus spines—and their different functions—and to learn about the evolutionary conversion of leaves to spines in cacti.

What is a Trait? Genetic Science Learning Center (PDF) – Interactive tutorial on characteristics that are inherited and those that are learned or related to environment.

Signature Lesson

Bird Beak Buffet: My Science Box (website) - Students imitate feeding birds by using various utensils (forks, spoons, etc.) to simulate different bird beak shapes, and then measuring the relative effectiveness of each “beak” in picking up food. This activity is based on Charles Darwin’s research on finches on the Galapagos Islands.

Supporting Lessons

An Inventory of My Traits: Genetic Science Learning Center (PDF) - Students inventory their own easily-observable, inherited genetic traits; identify how their traits differ from those of other fellow students; and record their observations on a class bar graph. Includes Spanish language student sheets.

Elaboration Lessons and Extensions

Family Traits Trivia: Genetic Science Learning Center (PDF) - In this take-home game/activity, students identify the shared and unique traits among their family members. Includes a Spanish language version.

Assessment Ideas

Develop a bank of questions about inherited traits and learned behaviors, and then hold a quiz show-style competition in which teams of students compete to answer questions.
