Science Chapter 1

The measure of how much surface an object has is called its

• Volume

• Mass

• Area

• Weight

The measurement of the average energy of an object is called

• Temperature

• Mass

• Volume

• Area

What is a scientific law?

• A summary of many experiments' results and observations

• A statement of what WILL happen in a specific situation

• A statement of what you think will happen in a specific situation

• Both A & B

If you wanted to examine a living person's brain tissue, you would use:

• A CT or MRI scan

• A transmission electron microscope (TEM)

• A computer

• A compound light microscope

The scientific method

• Is used by all scientists in exactly the same way

• Is strict and rigid, without much room for creativity

• Is a series of steps used to answer a question

• Is accurate only if each step is done in the official order

A scientific theory is:

• Well supported by many observations and experiments

• Usually just a scientist's best guess

• A hypothesis that has not yet been tested

• A hypothesis that has been proven incorrect

Which of the following SI units would you use to measure the weight of a rat

• Kg

• Mm

• Liters

• Yards

• Pounds

What causes scientific knowledge to change?

• When experiments are done wrong

• When conclusions of a controlled and tested hypothesis prove something new or different

• When two different scientists do different experiments

• When the president says so

The amount of matter that an object is made of is called its

• Area

• Surface area

• Volume

• Mass

Which of the following is NOT essential to life science?

• Asking Questions

• Giving Lectures

• Making Observations

• Being Curious

• Forming Hypotheses

What is technology?

• Electrical models of experiments

• The application of science for practical purposes

• The creation of spreadsheets

• A way to look at tiny objects

What are the three types of scientific models?

• Physical, Visual and Tactile

• Conceptual, Mathematical and Scientific

• Mathematical, Conceptual and Physical

• Simple, Complex and Futuristic

A controlled experiment

• Keeps things from getting too dangerous

• Tests only one factor at a time

• Is a practice or "warm up" experiment

• Doesn't allow much creativity

To find the volume of an object, you would

• Multiply length and width

• Multiply length, width and height

• Measure how much fluid the object displaces

• Either B or C

The one factor that differs in a controlled experiment is called the

Why do scientists try to test many individuals in a group experiment?

• To have more fun

• To get a lot of different opinions

• To be certain difference are caused by the variable and not by the differences in individuals

• The more organisms tested, the more certain scientists can be of the data

• Both C and D

After making an observation, the study of life science usually begins with a simple

If you want to view something that is not living in a 3D image, you would use:

• Compound Light Microscope

• Transmission Electron Microscope

• Scanning Electron Microscope

• A magnifying glass
