Performance Standard Level 2, Ages 8–10

Students identify characteristics of plants and animals that are inherited as well as characteristics of plants and animals that are influenced by the environment.

Sample Assessment Ideas

Sample Assessment Ideas

  • Students examine the phenomenon of “snowballing” on dogs’ feet; identify the characteristics of the dog and factors of the environment that affect this tendency.

  • Students grow FAST® plants for two generations; keep a journal with details about inherited characteristic (leaf shape, flower color, number of seeds and so on.)

Plants and animals closely resemble their parents. (Page 129)

Many characteristics of an organism are inherited from the parents of the organism, but other characteristics result from an individual’s interactions with the environment. Inherited characteristics include the color of flowers and the number of limbs of an animal. Other features, such as the ability to ride a bicycle, are learned through interactions with the environment and cannot be passed on to the next generation. (Page 129)

The characteristics of an organism can be described in terms of a combination of traits. Some traits are inherited and others result from interactions with the environment. (Page 157)



Some likenesses between children and parents, such as eye color in human beings, or fruit or flower color in plants, are inherited. Other likenesses, such as people’s table manners or carpentry skills, are learned. (Page 107)

For offspring to resemble their parents, there must be a reliable way to transfer information from one generation to the next. (Page 107)
