Instructions: Explore how food travels through the digestive system, how different teeth help us eat, and how food chains show feeding relationships. Read each question carefully and use the clues provided. Write your answers in the boxes.

Follow the Food Journey

Use the word bank to name parts of the digestive system. The parts are listed in the order that food travels through the body. Choose each word once; the first answer is given as an example.

Word bank: mouth, oesophagus, stomach, small intestine, large intestine, anus

Example. Food is chewed and mixed with saliva in the mouth.

1. Food travels from the mouth down the ___.

2. Food is churned and mixed with digestive juices in the ___.

3. Most nutrients from food are absorbed in the ___.

4. Water is absorbed from the remaining food in the ___.

5. Waste leaves the body through the ___.

Meet the Teeth

Read each clue and write the type of tooth that best fits. Use the word bank to help you. Think about the shape of each tooth and the job it does when you eat.

Word bank: incisors, canines, premolars, molars

1. These front teeth cut and bite food.

2. These pointed teeth help tear food.

3. These teeth help crush and grind food; they are between the canines and molars.

4. These large back teeth grind food into smaller pieces.

5. Which type of tooth would be especially useful for biting into an apple?

Tooth Jobs: Choose the Best Answer

Circle the best answer for each question. Each question has one correct answer. Use what you know about tooth shapes and their jobs.

1. Which teeth are usually at the front of the mouth?

2. Which teeth are pointed and help tear food?

3. Which teeth are usually the largest and are found at the back?

4. What is one important job of teeth?

Build the Food Chain

A food chain shows how energy passes from one living thing to another. Use the word bank to complete each chain. The arrows mean “is eaten by”; the first chain is completed as an example.

Word bank: grass, rabbit, fox, leaves, caterpillar, bird, algae, small fish, large fish

Example. grass → rabbit → fox

1. leaves → caterpillar → ___

2. algae → ___ → large fish

3. grass → ___ → fox

4. In the chain grass → rabbit → fox, which living thing is the producer?

5. In the chain leaves → caterpillar → bird, which living thing eats the caterpillar?

Science Check-Up

Use the facts in each question to answer in a word or a short phrase. Remember: digestion breaks food down, while a food chain shows feeding relationships between living things.

1. What is the name of the tube that carries food from the mouth to the stomach?

2. Which part of the digestive system absorbs most nutrients from food?

3. Which type of tooth cuts food at the front of the mouth?

4. In the food chain grass → rabbit → fox, what does the arrow from rabbit to fox tell us?

5. Name the first living thing in this food chain: algae → small fish → large fish.
