Purpose, Question, or Problem:
The purpose of this experiment is to investigate the growth
of mold on preservative-free bread and how environmental conditions, including light and
temperature, affect its development. Specifically, we aim to determine whether the rate of mold
growth differs when bread is exposed to different conditions.
Hypothesis:
If the bread is exposed to various environmental conditions, such as warmth, light,
and darkness, then the rate of mold growth will vary. I hypothesize that the bread placed in a
warm location will exhibit the most mold growth, followed by the bread in a well-lit area, and the
least mold growth will be observed in the dark.
Materials:
1.
3 slices of preservative-free bread
2.
Damp paper towels (3)
3.
Ziploc bags (3)
4.
Tape
5.
Warm location (Window sill)
6.
Well-lit room location (kitchen)
7.
Dark room location (cabinet in kitchen)
8.
Phone for photos
9.
Marker for labeling
10. A notebook for recording observations
Below are the summarized observations of mold growth on the bread slices during the 14-day
experiment. The percentage of mold growth is estimated visually

The World Health Organization (WHO) recommends us to limit "free sugar" intake to no more
than 5 % of the total daily Calories consumed. Sugars like sucrose are considered "free
sugars" and provide about 4 Calories per gram. If an individual consumes 2000 Calories in a
day, what is the maximum amount of sugar they are advised to take in? How does this amount
compare to the added sugars found in popular soft drinks?

While stored at 5.00C, the sucrose hydrolyzes to produce glucose and fructose. The mixture of the glucose and fructose is a liquid called invert sugar. Below you will find the concentration of sucrose in the cake as a function of time. For the cherries to be edible, the 85% of the sucrose must be hydrolyzed.
Before you start to answer the question, create a data table that comprises sucrose concentration in units of moles per liter.
Write the chemical reaction that demonstrates the hydrolysis of sucrose.
With the data, determine how long it will take for 85% of the sucrose to be converted into…

Before slow cooking a meat (for example, in a crockpot/slow-cooker) you will often find instructions to sear the meat on high heat in an oiled skillet for a few minutes before transferring it to the crockpot. The searing is brief – not long enough to cook the meat thoroughly. Despite myth/legend, the searing will not “seal in the juices”. What is the searing for?

Greenwashing is a major problem. Companies will say they are using practices that benefit the environment while really not taking any steps to do so. An example is Terracycle - a company that is supposedly able to recycle non-recyclable plastics and by-products - but which went over a year without collecting products from any of their customers. How can consumers navigate the labels to determine if products are actually sustainable.
