Update Glossary

• Add these words and their page numbers to your glossary:– Digestive system– Ingestion– Digestion– Absorption – Elimination

Digestive System Facts• Unfortunately, germs can stick to food dropped on the

floor in less than five seconds.• Every time you lick a stamp, you consume 1/10 of a

calorie.• If your stomach didn't produce a new layer of mucous

every two weeks, it would digest itself.• People eat more popcorn when watching a sad movie as

compared to a happy one.• Food can get to your stomach even if you are hanging

upside down.• The small intestine is about four or five times larger than

the large intestine.

• The small intestine can be as short as 4.6 m (15 feet) to as long as 9.8 m (32 feet).

• And here is a picture of a pig’s digestive system:

Digestive System Card Sort

• 1st: Sort the cards as a table group. You can use your notes in this round.

• 2nd: Sort the cards as a table group. You cannot use your notes in this round.

Digestive System Card Sort Answers• Ingestion: esophagus, getting food into our bodies• Digestion: stomach, breaking food down into

smaller pieces • Absorption: villi, getting nutrients in the

bloodstream so cells can use them• Elimination: getting rid of waste products

• Note: – Mouth could be ingestion or digestion– small intestine could be digestion or absorption– Large intestine could be absorption or elimination

Complete your KWL chart

• Fill in the last column (Learned) with what you learned today. You need at least 3 ideas in this column.

Digestive System Worksheet

• Complete side one first before you go on to side two. This is by yourself.

• Whatever you don’t finish in class becomes homework.

Exit Slip Time!• Label your note card with your FIRST AND

LAST NAME, DATE, and HOUR. Labeling this correctly is worth one point.

Digestive System Stories

Today’s Plan

• Complete the White Bread Challenge to demonstrate the importance of one of the parts of the digestive system

• Create a digestive system story to further understand what exactly happens in the digestive system

White Bread Challenge

Now we will review a few important ideas

• Pay really good attention during the review or the next assignment you have will be difficult.

Review

• Remember that the digestive system’s functions happen in this order:– Ingestion (eating)– Digestion (smashing the food down)– Absorption (getting the nutrients from the food)– Elimination (getting rid of the waste)

Review • The food goes through the digestive system’s

organs in this order:– Mouth– Esophagus– Stomach– Small intestine– Large intestine

Digestive System Stories

• By yourself or in a group of up to three people, you will write a story about a piece of food’s journey through the digestive system.

• You have to pick a certain type of food and write the story from the point of view of the food. – Example: I’m a slice of pepperoni pizza from Papa

Johns. One day I was created in a very hot oven and delivered to some hairy dude’s house. After licking his lips, the hairy man chomped down on my crust! …

Digestive System Stories• Your food has to go through ingestion, digestion,

absorption, and elimination. You must mention each part of the body it travels through and what happens in each part of the body.

• Your story should be creative and the info on the digestive system must be accurate.

• Near the end of the hour we will read several stories and vote on the best one. The winners will get a prize next time they are in class.

Complete your homework!!

•Homework is due on MONDAY.
