she ran a fever
3) 3. What are some things that substances moving through the digestive system can do?
A
not exit the body
B
not change into something different
C
not convert into energy
D
move into other parts of the body, change into a different substance, convert things into energy, disappear
4) 4. What inside of M’Kenna’s digestive system looks similar to the healthy patient?

They all had a smooth lining
B
the coloring of both are similar and the lining of some of the organs look similar. They had ridges.
C
They all had the same amount of moisture in them.
D
They were all pink in color
5) 5. What inside of M’Kenna’s digestive system looks most different from the healthy patient’s?

D
The esophagus
7) 7. We know that matter can’t just disappear. What ideas do we have about what is happening to the molecules that are disappearing in the small intestine?
A
It is being absorbed by the spit in her mouth
B
It is being absorbed in her large intestine
C
They might be moving through the digestive system, it is changing into something else, it is disappearing, It is being absorb
D
They might be getting dissolved completely in her stomach by her stomach acid and not making it to her small intestines.
8) 8. What does the dialysis tube represent?
A
The dialysis is the mouth
B
The dialysis is the large intestine
C
The dialysis tube is the small intestine
D
The dialysis is the stomach
9) 9. What should the outside of the tube represent?
A
The outside of the tube is just the outside of the tube and doesn't represent any part of the human body.
B
The outside of the tube is the connection between the stomach and the small intestine
C
The outside of the tube is the outer lining of the small intestine
D
The outside of the tube is the rest of the body outside of the small intestine
10) 10. Did any of the food molecules end up on the other side of the dialysis tubing?
A
The sugar we put inside the dialysis tube disappeared completely.
B
The sugar we put inside the dialysis tubing ended up outside of it
C
The sugar we put inside the dialysis tube ended up settling at the bottom of the container and didn't show any reaction
D
The sugar we put inside the dialysis tube ended up just being dissolved and didn't move from the inside of the tube
11) 11. How do you know? What’s your evidence?
A
When we tested the outside of the tube with Benedict's, it turned orange
B
When we tested the outside of the tube with Benedict's, it turned blue
C
When we tested the outside of the tube with Benedict's, it turned green
D
When we tested the outside of the tube with Benedict's, it turned purple
12) 12. Did any food molecules stay inside of the dialysis tubing?
A
The starch we put inside the dialysis tube ended up melted and settled at the bottom of the container
B
The starch we put inside the dialysis tube ended up dissolved and didn't show up anywhere
C
The starch we put inside the dialysis tube ended up staying inside the tube
D
The starch we put inside the dialysis tube ended up moving to the outside of the tube
13) 13. How do you know? What’s your evidence?
A
When we tested outside of the tube with iodine, the color changed to red.
B
When we tested outside of the tube with iodine, the color did not change to black. It stayed brown.
C
When we tested outside of the tube with iodine, the color changed to purple
D
When we tested outside of the tube with iodine, the color brown disappeared and was translucent
14) 14. What do our results tell us about the structure of the dialysis tubing?
A
The material was not sealed completely at the top or bottom and the substances got out
B
The material of the dialysis tube is thick like a plastic bag and we had to put holes in it for it to work
C
the material of the dialysis tube was weak and didn't work
D
• There must be small openings/gates in the surface of the dialysis tubing.
15) 15. What structure in our bodies was the dialysis tubing similar to again?
A
stomach
B
large intestines
C
mouth
D
our small intestines
16) 16. How is it possible that some molecules can get through a structure like the dialysis tubing but not others?
A
The shape or size of the molecule of glucose must be different from a sugar molecule.
B
The shape or size of the molecule of a complex carbohydrate must be different from a starch molecule.
C
The shape or size of the molecule of a complex carbohydrate must be different from a sugar molecule.
D
The shape or size of the molecule of a protien must be different from a sugar molecule.
17) 17. What do our results tell us about what might be different about the structure of starch versus sugar molecules?
A
Maybe they decided to just not want to go through the pores/holes/gates in the surface
B
Maybe they are smaller and have a different shape that doesn’t fit through the holes/pores/gates in the surface.
C
Maybe they are bigger or have a different shape that doesn’t fit through the holes/pores/gates in the surface.
