FRIDAY, AUGUST 20TH

Warm-up:

What are the steps of the scientific method?

Homework: Project brainstorm

Answers to warm-up

Question Observe/ research Hypothesis Experiment Results Conclusion Communicate the Results

Questions?!?

Get a red textbook

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)

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?

Scientific Models

What is a model?A model is something that scientists use to

represent an object or processEx: Cells, Human body, buildings

There are Three Types of models

Physical Models

Mathematical Models

Conceptual Models

Physical Model

This type of model you can touch and see. For example a model of the solar system.

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

Conceptual model

A conceptual model is used to help explain ideas. Ex. Animal BehaviorScientists use conceptual models to predict

how an animal will behave.

What are some differences between models and the real objects?

Size – solar system made smallercells are made larger

Strength – dinosaur models will never tell how strong they were.

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.

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.

I.N. Intro to Engineering

Ask

What is the problem? What have others done? What are the constraints?

Imagine

What are some solutions? Brainstorm ideas. Choose the best one.

Plan

Draw a diagram. Make lists of materials you will need.

Make a prototype – or model -

Create

Follow your plan and create it. Test it out!

Improve

Talk about what works, what doesn't,

and what could work better. Modify your design to make it better. Test it out!

Design a rollercoaster

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?

What is Bioengineering?

Engineering things to help plants, animals, and people.

2 types of bioengineering

Interactive notebook pg. 4 bottom

Assistive

These technologies are developed to help organisms without changing them

Ex: contact lenses, hearing aides, crutches, canes.

Adaptive

Adaptive technologies change the living organism

Ex. Artificial skin, which heals wounds faster

Ex. Changing DNA.

Project

Working with a group of 2 or 3Create 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?
