Tuesday September 22nd In Notebook: How do you determine the size of an object when looking through a microscope?

Today’s Learning Targets Agenda: 1.Quiz 2.What is alive? Activity 3.Characteristics of Life Notes 4.REMINDER: Lab Report Due TODAY! 5.REMINDER: Test Thursday! **Please turn in the video consent forms ASAP! Thank you!**

What is living? AliveNever AliveOnce was alive (Dead) ** In your notebook: Explain why you are sorting them in this way. Be ready to discuss! **

What is biology? Study of life Biologists – study the structure, function, growth, origin, evolution, and distribution of living organisms.

Characteristics of life 1.Made of one or more cells 2.Displays organization 3. Grows and develops 4. Reproduces 5. Responds to stimuli 6. Requires energy 7. Maintain homeostasis 8. Adaptations evolve over time Organism

1. Made of one or more cells Cell – basic unit of life. Each cell has a specific structure and function. An organism can be… a.Unicellular – one cell b.Multicellular – many cells

Organisms are arranged in an orderly way. Cells have many parts that contribute to whole. 2. Displays organization

3. Grows and Develops Grow - Add mass or more cells Develop – natural changes during the life of organism

Produce offspring – pass on DNA!! Reproduce as a species not individual 4. Reproduces

React to factors outside/inside organism Examples: Plants and sun Predators/prey 5. Responds to stimuli

Keeping internal conditions stable/within a tolerable range Example for humans:  if body temperature rises, you sweat.  if body temperature lowers, you shiver. 6. Maintain homeostasis

Energy is used for growth, development, and maintaining homeostasis Metabolism - biochemical reactions that acquire & use energy Can obtain energy through: making food from light energy OR consuming food 7. Requires Energy

Adaption - inherited characteristic that resulted from a change in the species over time Allows a species to survive long enough to reproduce! 8. Adapts over time

Wednesday September 23rd In Notebook: Explain why a rabbit is considered an organism (aka – what makes it ALIVE?)
