Eight organs, eight jobs and three written questions make up this 3-page 5th grade science sheet. In Part 1 students write the letter of the right job beside the mouth, salivary glands, esophagus, stomach, liver, pancreas, small intestine and large intestine. Part 2 asks why we chew food, which organ absorbs most nutrients and why the large intestine matters. Page 3 is the answer key, with a model sentence for each written question.
“Match each organ of the digestive system to its job.”
Part 1 has eight organs and eight jobs, from teeth breaking food to the large intestine absorbing water.
“Explain why a step in digestion matters to the body.”
Part 2, questions 1 and 3 ask why we chew and why the large intestine is important.
A table of eight organs with a Letter column, next to eight jobs in mixed order (A to H). Examples are makes bile that helps break down fat and absorbs water and forms waste.
Three questions answered in sentences: why we chew food, which organ absorbs most nutrients and why the large intestine is important.
The letter for each organ, written out with its job, and a model answer for each of the three questions.
Mouth and salivary glands
Items 1 and 2 are the pair students most often swap. The mouth is matched with teeth breaking food, and the salivary glands with saliva that starts breaking down starch.
Juices
The stomach (A) and the pancreas (H) both involve juices. Ask students where each set of juices does its work before they commit to a letter.
Exit ticket
Use Part 2, question 1 alone at the end of the lesson. A sentence starter such as We chew food so helps students who stall.
