Introduction to Life Science Characteristics and Classification of Living Organisms
Thinking like a scientist

2. What is Life Science?

3. To begin studying living organisms scientists have a problem: How do we decide if something is living or non living?

4. Directions:
Cut out and read the following descriptions that apply to all levels of biology for all living organisms. Match each description to the correct Biology/Life Science theme and paste into the table. When the table is complete, paste cut and paste it into your Science Interactive Notebook.

7. Life Science…7th grade Biology
Biology is the study of living organisms also known as life science.
The life sciences comprise the fields of science that involve the scientific study of living organisms – such as microorganisms, plants, animals, and human beings – as well as related considerations like bioethics.

8. Learning Outcomes Classification
To be able to categorize living things based on careful observation of similarities and differences in characteristics.
Crosscutting concept: Patterns
NGSS Practice 6: Construct an explanation
7.S Use observations to make defendable inferences

9. Patterns CARD SORTING ACTIVITY 1
Patterns CARD SORTING ACTIVITY 1. In small groups sort your cards into groups Discuss the patterns in your cards. 3. When you agree on all cards being grouped (no single card groups!!!!), write your pattern down as the group characteristic. Example: Group 1: animals that have fur

10. Card Sorting Examples Group 1: animals with fur Group 3:
Group 2: animals that have slimy skin
Group 4:

11. Are there some cards that could fit into more than one group? Why?

12. Classification
Classification makes the identification of living organisms easier.
Organisms are sorted into groups according to features they have in common.
The biggest group is Domain.
Sorting goes from the biggest (broad) groups of organisms to the most specific.

13. Classification The basic unit of classification is the species.
A species is a group of organisms that can breed together to produce fertile offspring.
Naming Species
In the Binomial System organisms are identified by two names
Genus and species
Genus always has a capital letter
Examples
Canis lupus – the wolf
Panthera leo – the lion

14. Classification Groups

15. The five kingdoms *One-celled *One-celled with no membrane
*Has a nucleus
*One-celled with no membrane
*Multicellular
*Have to obtain food (does not make own food)
*2 main groups:
vertebrates and invertebrates
*Most are many celled
*Cell walls contain chitin and have a nucleus
*Multicellular
*Can make food through photosynthesis
