3. VOCAB ASSIGNMENT
EVERY UNIT, YOU WILL BE ASSIGNED A LIST OF VOCABULARY WORDS. THE TEACHER WILL GIVE YOU THEIR DEFINITIONS.
IT IS YOUR JOB TO FIND AT LEAST TWO EXAMPLES OF THAT VOCABULARY WORD BEING USED (MOST LIKELY YOU WILL FIND ALL OF YOUR EXAMPLES FROM CLASS).
WRITE THE EXAMPLES IN YOUR SPIRAL NOTEBOOK

4. Characteristics of Life!!!!!!
How do you know if an object is ALIVE?
It has to have ALL Seven
Characteristics of Life!!!!!!

5. Let’s learn about the 7 characteristics of life.

6. 1) ALL LIVING THINGS ARE MADE OF CELL(S)
A CELL IS THE SMALLEST
LIVING UNIT THAT CAN CARRY OUT LIFE PROCESSES
SCALE OF CELLS

7. Single celled (unicellular ) organisms -Organisms that are made up of only one cell.
They have everything they need to be self-sufficient.

8. In multi-cellular animals, the cells will perform specific jobs (bone cells, skin cells, muscle cells, root cells,
leaf cells).
Smooth muscle
Nerve cell
Leaf cell
Red Blood Cell
Yeast cell

9. 2) ALL LIVING THINGS USE ENERGY TO MAINTAIN HOMEOSTASIS
The SUN is the main source of energy on Earth!!!
The Sun makes light that is used by plants!!!!!!
What is the name of this process by which plants convert the energy from the sun into food?

10. #2 vocab word
Multicellular= animals w/more than one cell

11. Homeostasis-  is the ability to maintain a constant internal environment in response to environmental changes.

12. Plants (producers) trap the energy of the Sun and make glucose (sugar) in the process called photosynthesis.
AUTOTROPHIC organisms can make their own food

13. 4.HETEROTROPHic
Consumers (animals) get their energy from the plants!!!!
Can’t make their own food!

14. 3) ALL LIVING THINGS RESPOND TO A STIMULUS (plural-Stimuli)
Living things respond to immediate and long-term changes in their environment (shiver when cold, change fur color, plants bend toward light).

15. Responding to Stimuli
a. dogs pant when hot b. pupils dilate in lower light levels c. humans sweat when body gets too hot d. reflexes – touch hot stove, fight/flight

16. 4) ALL LIVING THINGS REPRODUCE
Reproduction must occur for a species to survive.
Reproduction can be either sexual or asexual.

17. ASEXUAL REPRODUCTION -Reproduction by one parent
3 Types of Asexual Reproduction
1. Budding – Hydra and Sponge
2. Fragmentation - Starfish
3. Binary Fission – unicellular organisms

18. ASEXUAL REPRODUCTION

19. 5) ALL LIVING THINGS GROW AND DEVELOP
To grow means to get bigger and to get bigger; more cells must be added.
To increase numbers of cells, cell division must occur.
Develop means to change into an adult form (mature).

20. 6) ALL LIVING THINGS CHANGE TO FIT THEIR ENVIRONMENT(ADAPT)
Organisms must adapt to changes in their environment or risk becoming extinct.
Adaptations occur over a very long period of time (millions of years).

21. Name some the adaptations of these organisms.

22. 7) ALL LIVING THINGS HAVE DNA.
DNA provides instructions for LIFE. making molecules called proteins. Proteins build cells.
DNA carries the genetic material from parent to offspring (heredity).

23. LET”S PRACTICE!!! Which characteristics of life is being described?
Reproduction
Cells
Adaptation
Grow and develop
Responses
Energy

24. Bellringer: Give an example of something living, dead and nonliving.
* Living organisms must show ALL 7 characteristics of life.
*Dead organisms ONCE showed ALL 7 characteristics but now do not.
*Nonliving things do not have all 7 characteristics.

25. BELLRINGERS Define: living, dead, nonliving.
2. Give examples of living, nonliving and dead objects.
3. Describe how you would know if an object is living or nonliving?
4. Define: multicellular, unicellular
5. Define: prokaryotic cell, eukaryotic cell
6. Define: taxonomy, classification, kingdom, organism

26. FLASH CARD GAME! WE WILL FORM TWO TEAMS
EACH TEAM IS COMPETEING AGAINST THE OTHER FOR EXTRA CREDIT
TEACHER WILL CALL ON ONE TEAM MEMBER FROM EACH TEAM
THE TWO STUDENTS WILL USE A WHITE BOARD TO WRITE OUT:
L = LIVING
D = DEAD/ ONCE-LIVING
N = NON-LIVING

27. Vocab unit 1-flash back Write in your vocab section of spiral ntbk
Unicellular- one celled organisms
In multi-cellular animals, the cells will perform specific jobs (bone cells, skin cells)
Heterotrophic- animals that must eat other plants or animals for their food
Autotrophic-organisms that can make their own food
Homeostasis-keeping conditions inside the body constant (example: temperature)
