1. Make four observations about the materials before they are combined. Observations
should be based on what you see, smell, feel, etc.
1. The food coloring we use is blue 2. The vinegar has a strong smell 3. The milk is cloudy
and cold 4. The Vinegar in the cup is clear but not clearer than water
2. Form a hypothesis regarding what will occur when the materials are combined.
Remember that a hypothesis is a testable statement.
When the materials are combined together will make everything turn blue as well as cause
a chemical reaction due to the vinegar being added to the hot milk
Heat the milk and food coloring in a 400 mL beaker on a hot plate until hot but not boiling. Add
the vinegar and stir. Pour the mixture through the coffee fi
lter in a strainer into a bucket. Rinse
with cold water at the sink and collect the materials on the strainer. Once cool enough, shape the
materials and form into a mold. Allow the new material to cool and harden before you continue.

3. What occurs when the materials are combined? Was your hypothesis correct?
My hypothesis was correct, when all of the materials were added, a chemial reaction
occured causing the vinegar to not mix with the milk and become clumpy
4. Describe the new material you created. Were the results surprising?
I created a clumpy seperated type of material that wont mix together no matter how much
you stir it. The results were suprising i did not expect the vinegar to not mix with the mix
5. Now do some of your own experiments using the resulting substance. Come up with two
questions, hypotheses, and results.
a. Question 1:
Hypothesis 1:
Result:
b. Question 2:
Hypothesis 2:
Result:
a.Question: I wonder what will happen if you let the materials cool down? Hypothesis: The
items when cooled down will eventually mix together Results: When the materials cool

down they did not mix togther, instead it looks even more seperated b. Question: What
does this new created material feel like? Hypothesis: I think that the material will feel wet
and sticky Result: The material feels wet and sticky. It is also not that strong it is easy to
break apart.
6. What is your product?
From the expeirment we conducted the product that was made was a type of plastic that
can be used.
7. Was this a good method for creating your product? How is this product prepared
commercially?
This is a easy way to make this product but not necessarily the best way to make it.
8. Scientists have been able to identify and explain many aspects of our world by using the
scienti
fi
c method. Name three important scientists and their contribution to
environmental science.
1. John H Seinfeld known for his reasearch into air pollution primary the properties of
aresol. Published many articles on why aresol is not healthy for the enviorment. 2.Aldo
Leopold known for his reasearch on better ways to protect wild life and the nature. He
discoverd many wildlife managment techniques that we use today. 3. James Hansen

The thin outer layer of Earth, called the crust, contains only 0.50% of Earth's total

elements such as oxygen, nitrogen, and a few other gases). Silicon (Si) is the second
most abundant element in Earth's crust (27.2% by mass). Calculate the mass of
silicon in kilograms in Earth's crust. (The mass of Earth is 5.9 × 10²¹ tons.

Solving for a reactant in solution

One way the U.S. Environmental Protection Agency (EPA) tests for chloride contaminants in water is by titrating a sample of silver nitrate solution. Any chloride
anions in solution will combine with the silver cations to produce bright white silver chloride precipitate.
Suppose an EPA chemist tests a 200. mL sample of groundwater known to be contaminated with iron(II) chloride, which would react with silver nitrate solution
like this:
FeCl,(aq) + 2 AgNO3(aq) → 2 AgCl(5) + Fe(NO3),(aq)

The chemist adds 11.0 mM silver nitrate solution to the sample until silver chloride stops forming. She then washes, dries, and weighs the precipitate. She finds
she has collected 8.9 mg of silver chloride.
