Mixture B

Part III. Determine the Mass % of Elements in each Compound:
K2SO4 - Potassium Sulfate
(Show Math Here)
K- (2)40=80/176= 45.5
S-(1)32=32/176= 18.2
O-(4)16= 64/176= 36.4
Total = 176

Na3PO4 - Sodium Phosphate
(Show Math Here)
Na- (3)23= 69/164= 42.1
P- (1)31=31/164=18.9
O-(4)16= 64/164=39
Total= 164

IV. Conclusion:
Explain the difference between Mixtures and Compounds using data. Compare the pie
charts.
There are a differences between Mixtures and Compounds. A mixture is substance
made by mixing other substances together. A compound is a Substance formed from two or
more elements in which the exact combination and proportion of elements is always the same.
According to the data it explains how mixtures are made up of more than one substances or
objects. Some of the key differences are that compounds are always homogeneous, whereas
mixtures can be homogeneous or heterogeneous. The compound is a pure substance, which
contains only one kind of molecule. As against this, a mixture is an impure substance which
contains various types of molecules. The compound, results in the making of the new
substance, while mixture does not lead to the creation of new substance. Compounds are boiled
or melted at a definite temperature. On the other hand, mixtures, do not have a fixed melting
and boiling point.

Explain how you separated the Salt from the Sand. Use as much new vocabulary as
you can.

You can separate salt from sand by making a funnel then pour the sand threw a filter
with water and the salt will go with the water. The water will then collect the salt. If you then boil
the water with the salt in it, the water will evaporate while the salt stays at the bottom. The salt is
the solute and the water is the solvent. A solute is the substance that is the substance that will
be dissolved and the solvent is the substance that is holding the solute while it’s being
dissolved. When the water is put through the funnel it creates a positive and negative charge
between the salt and water. A solvent is the substance in which the solute is dissolved. Then
saturated means any solution that contains all the solute it can hold at a given temperature. On
the other hand unsaturated is any solution that can dissolve more solute at a given temperature.

Science Portfolio Reflection:

What was your favorite science activity or topic this year? Why did you enjoy this activity? Be
specific
My favorite science activity this year was making videos to teach the class about GPE I enjoyed
this activity most because it was fun putting together a helpful video to benefit others. Plus,
while watching my other classmates videos it helped me understand the concept more.

2. Which topic or skill did you find to be the most challenging? Explain
I found the most challenging topic to be memorizing elements on the periodic table. I found this
the most challenging topic because it's hard for me to memorize orders and numbers and all of
it together was pretty difficult.

3. Provide an example of 3 types of graphs that were used this year in science? Why did it
make sense to use these graphs for those activities?
One example of a graph we used this year was a bar graph and second type of graph was a line
graph and lastly, a pie chart. It made sense to use these graphs because it showed the
difference in substances, change in IV and DV and many other things that were helpful during
experiments.

4. What were the key tips you remembered about solving math problems in science this year?
Word problems? Provide an example from this portfolio of a science math problem that was
challenging to solve this year.
Key tips I remembered about solving math problems was keeping everything neat and
organized. For example, keeping equal signs even underneath each other. For word problems a
key tip I remember is underline or highlight the important information that will be needed for the
work.

5. Which lab conclusion or sample of writing are you most proud of in this portfolio?
The lab conclusion that I am most proud of is the conclusion on page 62 to I thought it was the
best i've written all year because it had detail and a lot of information and evidence.

6. What are you excited to learn about in science next year? Do you want to pursue a career in
the sciences? Explain
I am excited to learn about the earth and minerals in the earth, this has been one of my favorite
topics to learn about since 6th grade because we covered it for two days but never got in debt
bout it. I think it would be a great opportunity to learn more about it and be able to teach others
about it. I do want to pursue a career in science because I would like to be a doctor. Although
that probably won't happen unless I all of a sudden become good at math and science. If that

plan doesn't work I would rather be a teacher and teach elementary school children about
science or math.
