What is the Scientific Method?

A way of answering a scientific question or problem.

1

What is Biology?

The study of living things.

2

What are observations?

Data we collect using our senses.

3

What is a Qualitative observation?

information that uses descriptions.

4

What is a Quantitative observation?

information that uses numbers and measurements.

5

What is a Hypothesis?

A possible explanation to a scientific question or observations

6

What is an experiment?

An organized way to test a hypothesis.

7

What variable is changed deliberately by the experimentor?

independent

8

Which variable is the result (response) to what you are testing?

dependent

9

Which variable is used as a comparison, to prove your results are due to what you are testing?

control

10

Which variable never changes during the experiment?

constant

11

This was the theory that living things came from non-living matter. Like mice come from bags of grain or fish come from mud.

Spontaneous Generation

12

All living things are composed of these...the smallest unit of life.

cells

13

Living things, when it comes to cells, can be either _______ or _______.

unicellular, multicellular

14

This is the process of creating more living things.

reproduction

15

reproduction that involves only one parent cell.

asexual

16

reproduction that involves two parent cells

sexual

17

All living things will grow and develop, meaning they have a...

Life cycle

18

This is a collection of chemical reactions that either produce or use energy.

Metabolism

19

A tree changing colors, dogs shedding, you changing your wardrobe, bacteria moving away from light...

Response to stimuli

20

This is the process living things use to maintain a relatively stable internal environment

homeostasis

21

This is the theory that all living things change over time

evolution

22

This is a set of measurements, based on 10's, that is standard in all areas of science

metric system

23

This is a device that produces a magnified image of an object that is too small to see with the unaided eye.

microscope

24

This microscope will pass a beam of electrons over the surface of a sample to create a 3D image up to 1 million X magnification

scanning electron microscope

25

This type of microscope uses a electrons to pass through thin sample to create an image up to 1 million X magnification.

transmission electron microscope

26

The process of living things with favorable traits surviving and reproducing.

Natural selection

26

Favorable traits in an organism.

Adaptations

26

This area of biology shows unity...it's all the interactions of diverse living things with each other and their environment.

Ecology

26

This is needed to share work with others for review. It also keeps the scientist honest and unbiased.

Communication.

26

This is the process of checking your results to see if they are reliable and support your hypothesis (or not).

Analyzing your data!

27

Cells working together

Tissue

28

Groups of tissues with similar functions

Organ

29

A series of organs performing a function

Organ System

30

More than one organ system working together

Organism
