Gallery Walk: Living and the Nonliving (5 minutes) • Directions: Using your observation skills,

Gallery Walk: Living and the Nonliving (5 minutes) • Directions: Using your observation skills, make a list of the nonliving and living things you discover in each of the illustrations. • Make a list of both the living and nonliving things that you find in the chart in your guided notes. • You will have 1 minute in each station.

Turn and Talk: What’s my rationale? • How did you determine which things in

Turn and Talk: What’s my rationale? • How did you determine which things in the pictures during the gallery walk were living versus nonliving things?

INM: Characteristics of Living Things (10 -12 minutes) • There exists a set of

INM: Characteristics of Living Things (10 -12 minutes) • There exists a set of characteristics that ALL living things share. • Something” that does NOT have ALL of these characteristics is said to be nonliving

Characteristic 1: Synthesis • ALL living things have the ability to make new things

Characteristic 1: Synthesis • ALL living things have the ability to make new things Example: • These “new things” include the production or synthesis of: - Proteins such as hormones or enzymes

Characteristic 2: Transport • ALL living things have the ability to move in their

Characteristic 2: Transport • ALL living things have the ability to move in their environment and move substances internally • Examples: – Move in their environment: walk, run, gallop – Move substances internally: diffusion and active transport

Characteristic 3: Reproduction • All living things have the ability to produce new offspring

Characteristic 3: Reproduction • All living things have the ability to produce new offspring or cells • Examples: – Cells: mitosis (cell division)

Characteristic 4: Respiration • ALL living things have the ability to exchange gases with

Characteristic 4: Respiration • ALL living things have the ability to exchange gases with the external environment • Example: – We breathe in oxygen and breathe out CO 2 – Plants take in CO 2 and release oxygen through their leaves

Characteristic 5: Regulation • ALL living things have the ability to control your internal

Characteristic 5: Regulation • ALL living things have the ability to control your internal environment. • Example: – The process of diffusion/osmosis makes sure your body has a balance of molecules inside and outside of the cells in your body

Characteristic 6: Excretion • ALL living things have the ability to remove waste from

Characteristic 6: Excretion • ALL living things have the ability to remove waste from the body • Example: – Urination – Breathing out CO 2

Characteristic 7: Nutrition • ALL living things have the ability to take in specific

Characteristic 7: Nutrition • ALL living things have the ability to take in specific elements that they need from their environment • Example: – A plant taking in water and nutrients from the soil – You eating breakfast, lunch or dinner

Characteristic 8: Growth • ALL living things have the ability to increase in size

Characteristic 8: Growth • ALL living things have the ability to increase in size and number of cells • Example: – What would be an example?

Characteristic 9: Metabolism • ALL living things have the ability to perform chemical reactions

Characteristic 9: Metabolism • ALL living things have the ability to perform chemical reactions that allow for energy to be made and used. • Metabolism converts the fuel in the food we eat into the energy needed to power everything from moving to growing. • Example: – break down the sugar in our foods to make energy

Characteristic 10: Homeostasis • ALL living things have the ability to maintain a stable

Characteristic 10: Homeostasis • ALL living things have the ability to maintain a stable internal environment regardless of their external environment • Example: – What would be an example of homeostasis?

Activity 1: Making Connections (10 minutes) • What do the terms abiotic and biotic

Activity 1: Making Connections (10 minutes) • What do the terms abiotic and biotic factors mean? • Are these terms the same as saying living versus nonliving things?

Biotic and Abiotic factors • Biotic Factors • Abiotic Factors – All the living

Biotic and Abiotic factors • Biotic Factors • Abiotic Factors – All the living things – or the materials that directly or indirectly affect an organism in its environment – Those non-living physical and chemical factors which affect the ability of organisms to survive and reproduce. – For example: • All living things (plants and animals) • Waste from an organism • An organism’s body parts • Light intensity, temperature, soil type, p. H, level of pollution, and water

Discussion (5 minutes) • Looking at the list you made during the gallery walk

Discussion (5 minutes) • Looking at the list you made during the gallery walk of living and nonliving things: – Are all of the things on your “living” list biotic? – Are all of the things on your “nonliving” list abiotic?

Why are we learning about abiotic and biotic factors? !

Why are we learning about abiotic and biotic factors? !

Unit 7: Ecology is the study of the interactions between organisms and their interactions

Unit 7: Ecology is the study of the interactions between organisms and their interactions with their environment. In other words, it is the study of the relationships between biotic and abiotic factors that exist within a given environment.

Components of Ecology • There exists a hierarchy of organisms and the relationships between

Components of Ecology • There exists a hierarchy of organisms and the relationships between these organisms and their environment. • In this next activity, you will explore this hierarchy that exists

Activity 2: Hierarchy of an ecosystem • Directions: Using the Power. Point titled “Ecology

Activity 2: Hierarchy of an ecosystem • Directions: Using the Power. Point titled “Ecology Hierarchy”, respond to the questions in your guided notes. • You will have 10 minutes to complete this activity.

Activity 3: Interdependence (10 -12) • Directions: Watch the following video from the Discovery

Activity 3: Interdependence (10 -12) • Directions: Watch the following video from the Discovery Channel and respond to the questions in your guided notes • https: //www. youtube. com/watch? v=gk-4 x 6 cj. KY
