- MARCH 8, 2013Q-2 PG. Daily Goal: We will be able to sort and
explain the importance of the biotic and abiotic factors of our
ecosystem. Homework: Revise your test; finish your comic strip.
Science Starter: 1.Explain transpiration. 2.How might plants be
different if they didnt have guard cells? 3.What do the stomata
control?
- Slide 2
- WHAT DOES BIO MEAN? What are some examples? Biology Biomedical
Biography Biodegradable Biodiversity Antibiotic
- Slide 3
- CAN YOU THINK OF MORE?
- Slide 4
- WHAT DOES BIO MEAN? What are some examples? Biology Biomedical
Biography Biodegradable Biodiversity Antibiotic What do these words
have in common? LIFE!!
- Slide 5
- WHAT DOES THE PRE-FIX A MEAN? What are some examples?
Asymptomatic Asymmetrical Amoral Atypical What is a prefix?

- CAN YOU THINK OF MORE?
- Slide 7
- WHAT DOES THE PRE-FIX A MEAN? What are some examples?
Asymptomatic Asymmetrical Amoral Atypical What do these words have
in common? Not!!
- Slide 8
- AN ENVIRONMENT HAS TWO PARTS Biotic: the living parts of an
environment Abiotic: all the physical factors (like water, soil,
light and temperature) or things that are not living that affect
living things in that area
- Slide 9
- How many living and non-living things can you name in this
picture?
- Slide 10
- WHAT ARE THE CHARACTERISTICS OF LIVING THINGS?
- Slide 11
- If were unsure whether an element is biotic or abiotic, we can
use the characteristics of living things to help us out! Living
things can grow or change Living things can reproduce Living things
can use energy
- Slide 12
- Biotic elements must have ALL characteristics of living things,
so if you cant eliminate one characteristic, check out the others!
Ann Marie doesnt know whether the Sun grows over time, but she
knows the Sun CANNOT reproduce. IS THE SUN ABIOTIC OR BIOTIC?
WHY?
- Slide 13
- 1. A lynx: ____ Is it made of cells? _____ Does it grow or
change? _____ Does it reproduce? _____ Can it use energy? Is this
an example of a biotic or an abiotic element?: _______________
- Slide 14
- 2. A weeping willow tree _____ Is it made of cells? _____ Does
it grow or change? _____ Does it reproduce? _____ Can it use
energy? Is this an example of a biotic or an abiotic element?:

- 3. WATER _____ Is it made of cells? _____ Does it grow or
change? _____ Does it reproduce? _____ Can it use energy? Is this
an example of a biotic or an abiotic element?:

- Slide 16
- LETS GIVE IT A TRY! We live in an ecosystem (remember this word
for later) that depends on biotic and abiotic factors. Challenge:
Challenge: Find and sort the most abiotic and biotic factors out of
everyone in the class.
- Slide 17
- DRAW THIS IN YOUR NOTEBOOK: BioticAbiotic__
- Slide 18
- CHALLENGE DETAILS: You will have 5 minutes outside. In that
time, you will have to find and sort as many biotic and abiotic
factors as you can. The winner will get a no homework pass.
- Slide 19
- REMEMBER THAT WORD THAT I TOLD YOU TO REMEMBER FOR LATER? Who
was paying attention? (I feel a table group point coming on!)
- Slide 20
- ECOSYSTEM! Ecosystem- All the biotic and abiotic factors in an
environment put together.
- Slide 21
- EVERYTHING IN NATURE IS CONNECTED Think about this: Alligators
dig underwater holes to escape from the heat. Later, after the
alligators abandon their holes, fish and other aquatic organisms
live in them when the water level gets low during a drought.
Alligators also build nest mounds in which to lay their eggs, and
they enlarge these mounds each year. Eventually, the mounds become
small islands where trees and other plants grow. Herons, egrets,
and other birds build their nests in the trees.
- Slide 22
- CRITICAL THINKING! How might our ecosystem change if we didnt
have abiotic factors? Would it matter? Be ready to explain!
- Slide 23
- Biotic and Abiotic Factors How would you describe this
ecosystem? What abiotic factors play a role in this ecosystem? What
biotic factors play a role in this ecosystem?
- Slide 24
- Biotic and Abiotic Factors Biotic Factors: Abiotic Factors 1.

- Slide 25
- Biotic and Abiotic Factors How do the biotic and abiotic
factors interact? Without the soil, sunlight, and the warm
temperature none of the biotic factors (plants and animals) would
be able to survive.
- Slide 26
- Biotic and Abiotic Factors How do the biotic and abiotic
factors interact? Without the soil, sunlight, and the warm
temperature none of the biotic factors (plants and animals) would
be able to survive.
- Slide 27
- For the next 3 slides: List the biotic factors. List the
abiotic factors. List the climate. Write at least 3 sentences
explaining how the biotic and abiotic factors are
interconnected.
