Sugars

Team 1

The group’s hypothesis

If bacteria is exposed to 3 different types of sugars: light fructose corn syrup, cane sugar, and honey on 15 individual Petri dishes for a period of 1 week, then the bacteria with the light fructose corn syrup will grow a substantial amount of bacteria compared to the plates with the cane sugar and the honey because the light fructose corn syrup is full of the added chemicals from the production of corn and when the unhealthy sugars are added to the corn syrup, it will cause a greater reaction because it stimulated the bacteria.

Skills and/or techniques that they used to complete their lab.

• Know how to evaluate bacteria and how to see it underneath a microscope 

• How to evaluate bacteria  growth

• How to grow bacteria effectively using sugar as a main factor of the growth. 

The results of the lab

Honey promoted the most bacterial growth out of all 4 of the petri dishes which denies our hypothesis.

What would the group do differently

• Factor in  the granulation of the sugar

Questions and/or comments about the group’s lab.

Why did they cut off the tips of the swabs?

Team 2

The group’s hypothesis

If six students, three boys, three girls, get their glucose levels tested for one week on their regular diet then three more weeks while substituting in honey, sugar, and corn syrup into their diet then the corn syrup will have the greatest increase in glucose levels, because corn syrup has a higher glycemic index in it which increases the blood sugar, and the higher the glycemic index the higher the glucose levels are.

The results of the lab

The people that ate honey had higher glucose levels than those who ate the other sugars.

What would the group do differently

• Take a reading before and after eating

Questions and/or comments about the group’s lab.

Would changing the subjects' diet to only include their form of sugar?
