Science Chapter 1

1. Life science can be studied

In the forest

In Space

On a Farm

In the Ocean

All of the Above

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

Volume

Mass

Area

Weight

3. The measurement of the average energy of an object is called

Temperature

Mass

Volume

Area

4. 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

5. 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

6. 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

7. 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

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

Kg

Mm

Liters

Yards

Pounds

9. 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

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

Area

Surface area

Volume

Mass

11. Which of the following is NOT essential to life science?

Asking Questions

Giving Lectures

Making Observations

Being Curious

Forming Hypotheses

12. 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

13. What are the three types of scientific models?

Physical, Visual and Tactile

Conceptual, Mathematical and Scientific

Mathematical, Conceptual and Physical

Simple, Complex and Futuristic

14. 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

15. 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

Submit

17. 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

Submit

19. 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
