Pure Science
The search for facts about the natural world.
?
- In science, we often try to establish a cause-effect relationship.
- Driven by curiosity: the need to know, explore, conquer something new.

Applied Science
The practical application of scientific discoveries.

Corning Glass
NASA’s Problem Design a materialthat is clearclear and can with-stand extreme differences in temperature without fail-ing (cracking).
Corning Glass FAILED…but SUCCEEDED at making great cookware that can withstand extremes in temperature.
Design a face shieldto protect and provideclear vision.

Fertilizers (5-15-10)
Nitrogen (N)– Promotes vegetative growth, making the plants lush and
green– Excess nitrogen: few blooms (flowers)
Phosphorous (P)– Gives energy and vitality– Promotes rapid maturity and flowering
Potassium (K)– Promotes strong plant growth and deep roots– Helps plants become more disease-resistant
Fertilizers help plants produce more food.

saccharin A compound, C7H5NO3S, that is several hundred times sweeter than can sugar
and is used as a calorie-free sweetener.
Table Sugar = sucrose (glucose + fructose)
Formula: C12H22O11 [C12(H2O)11]
Dehydration of Sucrose:
C12H22O11 + 11 H2SO4 12 C + 11 H2SO4.H2O

weigh pros and cons before deciding
• Because there are many considerations for each case, “50/50 thinking” rarely applies.

Aluminum Mining
• Charles Martin Hall• 1850s: aluminum sold
for $500 / pound • Developed method to
extract aluminum from bauxite
• Hall’s method– 1 pound Al costs 30 cents
4-6 pounds bauxite
current 1 lb Al
