Inspirational Quote of the Day: "Imagination is more important than knowledge." - Albert Einstein
Objective: Why do large food molecules, like some complex carbohydrates, seem to disappear in the digestive system?
Standards:
Develop models to describe the atomic composition of simple molecules and extended structures.
Warm-Up:
Vocab Escape Room Race Starting Line
To Do List:
Read "What's Spit?"
Obtain information about saliva by reading an article called, “What’s spit?” Connect the information in the article to our ideas about what might be happening to complex carbohydrates in the mouth. - What's Spit? ---->Questions
6. Look for Patterns in Food Molecules-7min
Provide students with cards of molecular representations of complex carbohydrates, other than fiber, and glucose to use to look for patterns in their structures. Ask students to use these food molecules to explain whether chemical reactions could be happening in the mouth that could cause complex carbohydrates, other than fiber, to turn into glucose. - Food Molecule Cards
7. Plan an Investigation to Test for Chemical Reactions in the Mouth. 10 min
Ask students to brainstorm ideas for how we might investigate whether a chemical reaction is taking place in the mouth. Introduce the materials that students will use, and have students work in groups to create a procedure for determining if their selected food has complex carbohydrates and/or glucose in it.
Chemical Reactions in the Mouth
Data Table for Chemical Reactions in the Mouth
8. Conduct an Investigation to test For Reactions in the Mouth- 15min
Monitor students as they work in small groups in lab to complete parts 3-6 of the investigation
9. Building understanding Discussion- Interpreting Our Data- 10 min
Pull students together in a Scientists Circle. Ask students to make claims, supported by evidence, about whether chemical reactions occur in the mouth.
10. Navigation-3min
Students complete an exit ticket to help them think about where else in the digestive system chemical reactions occur.
