Science Unit C Project:
Understanding Impacts of Pure
Substances and Mixtures
Purpose:
Pure
substances and mixtures have many applications in our world – from day-to-day
living, such as flours for bread or salting the roads in winter, to large-scale
industrial uses like refining crude oil for gasoline or mining for precious
metals.
These
technologies all have impacts on our society
- socially, environmentally, and economically. (For reference, read
Section 9.2.]
You
task is to learn about real-life applications of pure substances and mixtures
and to inform others of the various implications these technologies have on
society.
Direction:
1.
In groups of 2-3 students, choose a topic from
the list below.
2.
Conduct research about your topic and
implications of the technologies involved.
3.
Prepare an oral presentation (approximately 5 minutes)
to share your findings.
Available Topics:
A.
Coal Mining
B.
Air filter/purification
C.
Pesticides
D.
Recycling plants
E.
Nuclear Energy (usage and disposal)
F.
Bottled water
G.
Oil Refineries
H.
Salt on the road
I.
Access to clean water in developing countries
In
your presentation, make sure you include the following:
·
Description of the use and application of
technology (including purpose of the technology)
·
Implications of the technology; choose any two
areas of implication: environmental, social, and/or economics
·
If applicable, provide alternatives to minimize
negative impacts
Effective
use of multimedia AND creativity
are strongly encouraged.
