This is their evidence:  If you add wood, the fire grows.  The fire needs oxygen to survive.  If a spark flies off and catches onto dry leaves, the fire reproduces.

 At the end of this lesson you should be able to support your answer using the basic characteristics of life.

 What makes something alive?  Brainstorm characteristics that living things have in common.

 Observe & Record Work with your group to make and record observations about the objects at each station.

 Claim After discussing each object’s characteristics, determine if it is alive.

 Support Use your recorded observations as evidence to support your claim.

 What are the characteristics of the objects that you claim to be alive?

Characteristics of LifeSample Student Responses Acquire Materials and Energyfood, water Reproduce Respond to stimuli (environment) light, temperature, water Grow and develop changes in physical form, to get bigger in size Biologically organized internal system, made up of one or more cells Homeostasis – maintain internal conditions body temperature, blood volume, pH balance, water balance Able to adapt (evolve)

 Using the characteristics of life discussed in class, explain to your friend why fire is not a living organism.  Use at least 4 CHARACTERISTICS OF LIFE to support your answer.
