What are our expectations?

What is expected for you to "Make good choices" in STEM?

In science, a model is a way to represent an idea, process, or system in order to describe, explain, or _____________ something.

Models help to explain things that are difficult to understand or difficult to ____________.

You cannot see your heart, but you can use a ______________ of a heart to explain how it pumps blood through your body.

Models help scientists think about possible answers to their questions about ____________.

Different models can be helpful because they may show different information about the same phenomenon.

All models have advantages and _______________. Even good models can often be made better.

A television is the light source. The television produces light that goes directly to your _________.

True or False. An image on television is both an object and a light source at the same time.

The difference between seeing an object and an image on television is that an object must have a light __________ that is bouncing light off of it for us to see it.

The dots of a TV screen create an ________ that looks like something real. These dots are called pixels.

Even if you can see the __________ up close, they are too small to be seen as individual dots when you stand far away.

Your brain does not see a bunch of little objects, because it puts them together to see the image on the ___________.

Long ago, artists in France painted in a style called pointillism. Images using ____________ are created by painting many tiny dots or points.

When you hear the word model, you might think of fashion models or model airplanes or model cars. Scientists use the word model in a special way.

In science, a model is a way to ____________ an idea, process, or system in order to describe, explain, or predict something.

Models help ___________ think about possible answers to their questions about phenomena.

Different models can be helpful because they may show different information about the same phenomenon. All models have advantages and disadvantages.

Even good models can often be made better. You will be learning how to evaluate models to decide what is good

and what needs to be ______________.

Scientists evaluate their own models and revise them when necessary. For example, new __________ make scientists think about a phenomenon in a new way.

Data is a word you will use over and over again in science. When scientists make observations, they take careful notes while they are _______________ something with their senses or measuring it with instruments.

When they use data to support an idea, they are using the data as ____________________.

To see an __________ you need Light, an eye, and an object and a straight or unblocked path between eye and object.

The dots you saw in the comic strip under the the magnifying glass are like the _________ referred to in the reading.

The purpose of building a model is to help each other think about how a person sees and to share our best ideas about what is happening.

Different models have different advantages, and no model is perfect. Creating models takes creativity and imagination for putting something together in a new kind of way.

A good scientific _____________ is consistent, meaning that it can account for all existing evidence.

We have evidence of 4 conditions that need to be represented in the model, a __________ source, an object, an eye and an unblocked path between the eye and the object.

In science, models are used to help people understand, describe, predict, and explain _________________ in the real world.

______________________ can be diagrams, physical replicas,and something as easy as a drawing.

Straight lines with ______________ are used to represent the path of light, with arrows showing the direction in which light is travelling.

Multiple arrows show that light travels from the _______________ source in all directions.

Light travels in all directions in three dimensional space. A model can only show the path of light on the plane of the paper.

Light is emitted in all directions from each point of a light source (light bulb or sun). Rays of light are shown to emanate in all directions from the light source.

The process of identifying important ideas, thinking and talking about how you will represent them, and creating the model is called MODEL CONSTRUCTION.

Models can be used to illustrate and explain what happens in a situation; they can be used to predict what will happen, and they can be used to communicate your thinking to others.

relating to the sense of sight

Once a scientific model is made, scientists do not change it.

Light CANNOT travel around corners.

Light has to enter your eyes in order for you to see something.

Four conditions needed to be met for an object to be seen-

1. an object

2. eye

3. source of light,
