3. 1
Theories vs Law
After scientists report the results of experiments, the results can be used to propose a scientific theory.
A scientific theory is an explanation of things or events based results of many observations and experiments.

4. Theories vs Law 1 A valid theory raises many new questions.
Data from new experiments might change conclusions and theories can change.

5. 1
Theories vs Law
A scientific law is a statement about how things work in nature that are true all the time.
Scientific Laws do not change.

6. Measuring with Scientific Units1
Measuring with Scientific Units
You will use the same standard system of measurement scientists use to communicate and understand each other’s research and results.
In science we always use the metric system when collecting and analyzing data.

7. Classification 4 Libraries group similar types of books together.
To classify something means you put similar units together.
All organisms are classified into groups according to similar characteristics.

10. Binomial Nomenclature4
Binomial Nomenclature
Binomial nomenclature is a two-word naming system that Linnaeus used to name the various species.
Binomial nomenclature is still used by modern scientists to name organisms.

11. Binomial Nomenclature4
Binomial Nomenclature
Latin is always used in binomial nomenclature because it is a dead language.
In binomial nomenclature the first word of the two-word name identifies the genus of the organism and is capitalized.
The second word of the name describes the organism and is not capitalized in binomial nomenclature.

12. Tools for Identifying Organisms4
Tools for Identifying Organisms
Tools used to identify organisms include experts, field guides, and dichotomous keys.
A field guide has descriptions and illustrations of organisms and information about where each organism lives.

13. 4
Dichotomous Keys
A dichotomous key is a detailed list of identifying characteristics that includes scientific names.
Dichotomous keys are arranged in steps with two descriptive statements at each step with a definite answer.

16. Student Dichotomous Key
As a simple example, you can construct a dichotomous key to identify people (or another group of items) in a classroom, using questions based on gender, hair length/color, glasses (or not), clothing color, etc.
Question 1: Is the person male or female? Question 2: Does the person wear glasses or not? Question 3: Is the person wearing blue jeans or not? etc.
The end of each branch of the key should be a person's name.
A dichotomous key will have enough questions to identify each member of the group. To test it, you can identify each person in the group by going through the key and seeing if the right name comes up.
