About this worksheet

What students practice

Students use parent and offspring records as evidence that plants and animals inherit traits.
Students compare data to describe trait variation within groups of the same kind of living thing.
Students distinguish conclusions supported by trait records from claims the records do not support.

How to use

Read the camping passage together. Have students connect each graph to the family records, then use counts and parent traits as evidence in their answers.

Curriculum

NGSS standard covered

Snails and Clover at the Tent Loop

Use family records to investigate traits and differences.

1. Investigate the Snail Families

Read the passage and family records. Use the records and graph to answer.

A Stop Beside the Tents

During a camping trip at Juniper Hollow Campground, Imani stops at a ranger's nature table beside the tent loop. The table has photographs and study records of grove snails and white clover plants. Grove snails can have different shell colors. White clover plants can have pale V-shaped marks on their leaves or leaves without those marks.

A trait is a feature of a living thing. Offspring are the young of parents. Each family record names two parents and describes their offspring. The ranger recorded shell color for the snails and leaf markings for the clover. The young plants had grown enough for their leaf markings to be clear. The records do not include the snails' speed or the plants' health.

Imani compares parents with their offspring. She also compares offspring within each family. She keeps the two kinds of living things separate: a shell color is not a leaf marking. The graphs combine the young from both snail families or both clover families. They do not include the parents. These small groups give Imani evidence to study, but they do not describe every snail or clover plant.

Ranger's snail family records
Family A parents: one yellow shell and one pink shell.
Family A offspring: 4 yellow shells and 2 pink shells.
Family B parents: two yellow shells.
Family B offspring: 6 yellow shells and 0 pink shells.
