About this worksheet

What students practice

Students sort body parts into cells, tissues, organs and organ systems.
Students use data to argue that the respiratory, circulatory, digestive and muscular systems interact.

How to use

Read the farm passage together, then have students describe the trend in the table in their own words before they answer. The last question works as a written argument.

Curriculum

Clover Runs Uphill

The Delgado family runs a small farm where they grow alfalfa hay and raise dairy goats. Each spring a vet, Dr. Okoro, checks every goat. This year Rosa Delgado, who is in seventh grade, helped record the data for a goat named Clover. Clover is three years old and has a mass of about 55 kg. That morning she had eaten her hay and had a long drink from the water trough.

First Dr. Okoro measured Clover at rest in the barn. She listened to Clover's heart with a stethoscope and counted heartbeats for one minute, then watched Clover's side rise and fall to count breaths. Next, Rosa led the herd up the hill to a new pasture, and Clover trotted and ran for about 5 minutes. Dr. Okoro measured her again as soon as she arrived, then 5 and 10 minutes later while Clover stood and rested. Rosa wrote each number in a notebook, and Dr. Okoro double-checked her counts.

While they waited, Dr. Okoro explained what happens to the hay Clover eats. A goat's stomach has four chambers that break the tough hay down with the help of tiny microbes. The small intestine then absorbs nutrients into the blood. The heart, a muscle organ made of heart muscle tissue, pumps that blood through blood vessels to cells all over the body, including the leg muscles. The lungs bring oxygen into the blood and remove carbon dioxide. Each muscle cell uses oxygen and nutrients from the blood to release the energy it needs to contract.
