REVIEW: Pure vs. Applied Science
Pure science addresses basic questions.Supports applied science.Restricted to abstract or theoretical concepts.For knowledge and research purposes.
Applied science solves specific problems.Suggests questions for pure science.Used in actual practice or to solve practical problems.For problem solving purposes.Often referred to as “technology”.

REVIEW: Examples of Pure Science
1. Scientists study human vision to learn how the eye works.
2. Students look through a microscope to see what’s inside a cell.
3. A biologist is experimenting on a plant’s reaction to lack of sunlight.
4. Anatomy, Cell Biology, Botany, Physics, Chemistry, Earth Sciences are all pure sciences.

REVIEW: Examples of Applied Science
1. Scientists invent motion pictures, eye glasses, and contact lenses.
2. Pharmacologists make and manufacture drugs and medicines.
3. Engineers create bridges and tall buildings.
4. Medicine, Computer Science, Engineering, Robotics and Technology are all applied sciences.

TECHNOLOGYCommon term for applied science.The application of scientific knowledge (pure science) for practical purposesUses concepts and ideas (pure science) to develop products that assist people in their daily lives
Aims to make living efficient and easier

Your book is a product of
technology!
![Page 8: Unit 1, Lesson 1.3 - Science and Technology](https://reader034.fdocuments.in/reader034/viewer/2022042615/55cae38cbb61eb39788b45e0/html5/thumbnails/8.jpg)
Without technology, you
would have to write all these things by
hand. That’s why books
back then were expensive because
it takes a lot of effort to finish
them.

You owe your thanks
to technology!
It aims to make your life easier.
