4. What is Technology? The products and processes that help us get our needs. The tools and methods for creating products and processes Any product, process, or knowledge that is created when a need is met (computer, coffee maker, hearing aide)
5. Interactive notebook pg. 5 Write the following questions What are three types of models used by scientists? What are some ways scientists use models? How do models differ from the object it represents? What is the difference between a theory and a law? Can theories change?
6. Scientific Models What is a model? A model is something that scientists use to represent an object or process Ex: Cells, Human body, buildings There are Three Types of models Physical Models Mathematical Models Conceptual Models
7. Physical Model This type of model you can touch and see. For example a model of the solar system.
8. Mathematical Model A mathematical model is made up of mathematical equations and data. Weathermen use this type of modeling with computers to make weather predictions
9. Conceptual model A conceptual model is used to help explain ideas. Ex. Animal Behavior Scientists use conceptual models to predict how an animal will behave.
10. What are some differences between models and the real objects? Size – solar system made smaller cells are made larger Strength – dinosaur models will never tell how strong they were.
11. How are models helpful? Models can be used to help explain theories. A theory explains why something happens and what will happen in the future. It is based on observation and testing. Theories can be proven wrong new theories can be made.
12. Scientific Laws When a theory and a model correctly predict the results of many different experiments the theory is considered a law. i.e THE LAW OF GRAVITY If I throw something in the air, it will come back down every time.
21. Negative effects of Technology Pollution from large factories CFC’s, were introduced to clean the environment, but actually made it worse Can you think of others?
22. What is Bioengineering? Engineering things to help plants, animals, and people. 2 types of bioengineering
27. Project Working with a group of 2 or 3 Create an assistive or adaptive bioengineered product. You need to answer the following questions and attach them to your poster board. What the product is called? What is does? Who/What will use it? How will you test it?
