  environment.
• Abiotic factors are all of the nonliving things
  in an environment.

Think about all of the abiotic and biotic factors
you might find in a pond
You have 15 seconds to write down as many as you
can think of

Do biotic and abiotic factors affect each other?
27
Do biotic and abiotic factors affect each other?

• If there is no watercan anything grow or
  survive?
• If it is extremely cold one winter, will that
  affect whether an animal makes it?

Do biotic and abiotic factors affect each other?

• If there is no watercan anything grow or
  survive?
• No!
• If it is extremely cold one winter, will that
  affect whether an animal makes it?
• No!
• So, abiotic and biotic DO affect each other. Even
  though water and temperature arent living
  things, they DO affect living things!

Independent Practice

• Tell me a story of about how abiotic and biotic
  factors play a role in your life.
• For example, Everyday morning I wake up and
  brush my teeth with toothpaste. Then I say hi to
  my mom and eat a bowl of cereal. I change my
  clothes, feed the dog, and walk outside to catch
  the bus. Sometimes I hear birds chirping on the
  way.
• Abiotic factors toothpaste, cereal, bus
• Biotic Factors My mom, my dog, birds
• You need to include at least 3 abiotic factors
  and 3 biotic factors and list them or draw them
  at the end.
