Agenda – 9/1/2015 Take out your notebook, name tent, and a pen or pencil! Bell-Ringer: Homer Scenario Living vs. Non-living and Characteristics of Life notes Think-Pair-Share w/ shoulder partner Tape/Glue outline in Notebook on Page 8 Exit Ticket – Sticky Note Homework: Syllabus/Lab Safety Contract, signature form on Moodle due by Fri. 9/4/15
1. On pages 1-4, divide the page into five sections to put your bell-ringers in this week (like below). 2. In the first box, Put the date and answer the bell question inside that box…We will use these entries for the next five weeks. Bellringers 1 Date Just like this!
The Homer Scenario Homer notices that his shower is covered in a strange green slime. His friend Barney tells him that coconut juice will get rid of the green slime. Homer decides to check this out by spraying half of the shower with coconut juice. He sprays the other half of the shower with water. After 3 days of "treatment" there is no change in the appearance of the green slime on either side of the shower. 1. What was the initial observation? 2. Identify the Control Group 3. Identify the Independent Variable 4. Identify the Dependent Variable 5. What should Homer's conclusion be? The Bart Scenario: Bart believes that mice exposed to microwaves will become extra strong (maybe he's been reading too much Radioactive Man). He decides to perform this experiment by placing 10 mice in a microwave for 10 seconds. He compared these 10 mice to another 10 mice that had not been exposed. His test consisted of a heavy block of wood that blocked the mouse food. He found that 8 out of 10 of the microwaved mice were able to push the block away. 7 out of 10 of the non-microwaved mice were able to do the same. 6. Identify the Control Group 7. Identify the Independent Variable 8. Identify the Dependent Variable 9. What should Bart's conclusion be? 10. How could Bart's experiment be improved?
Think about your answer and discuss with your shoulder partner. What is your definition of a living thing?
2.1 Section Objectives – page 35 Understand the five characteristics of life Today’s Objectives:
Section 1.1 Summary – pages 3-10 All living things depend upon other living and nonliving things to aid their survival. What are some living things you depend on? What are some non-living things you depend on?
Section 2.1 Summary – pages All the living organisms (or once living) are called biotic factors. All organisms depend on others directly or indirectly for food, shelter, reproduction or protection. BIOTIC FACTORS
Section 1.1 Summary – pages 3-10 Biologists have created a list of characteristics that something has to have in order to be considered LIVING. Only when something has ALL FIVE characteristics can it then be an organism. ORGANISM = A LIVING THING Characteristics of Living Things
Section 1.1 Summary – pages 3-10 Whether an organism is made up of one cell or billions of cells, all of its parts function together in an orderly, living system. 1. Made of Cells/Has an Orderly Structure This means that the organism has different parts that work together for a common function. (Like the organs in your body)
Section 1.1 Summary – pages 3-10 A species has to be able to reproduce in order to continue to exist. 2. Can Reproduce
If a female human is infertile (can’t have children)- does she cease to be a living thing?
Section 1.1 Summary – pages They can Grow and Develop Growth results in an increase in the amount of living material and the formation of new structures.
Section 1.1 Summary – pages 3-10 All of the changes that take place during the life of an organism are known as its development.
Section 1.1 Summary – pages 3-10 There are a lot of factors of the environment that can affect a living thing- water, temperature, weather, air, other organisms in the area. 4. They can adjust to changes in the environment
Section 1.1 Summary – pages 3-10 Anything in an organism’s external or internal environment that causes the organism to react is a stimulus. A reaction to a stimulus is a response.
Section 1.1 Summary – pages 3-10 When an organism automatically adjusts to maintain a balanced INTERNAL environment is called homeostasis.
Section 1.1 Summary – pages 3-10 Living things reproduce themselves, grow and develop, respond to external stimuli, and maintain homeostasis by using energy. 5. Can Metabolize food Metabolism is the breaking down or building of molecules in your body. Digestion is a type of metabolism
Section 1.1 Summary – pages 3-10 Organisms get their energy from food. 1. Plants and some bacteria make their own food 2. Animals, fungi, and other organisms have to EAT in order to get energy.
Section 2.1 Summary – pages The nonliving (never alive) parts of an organism’s environment are the abiotic factors. Examples of abiotic factors include: AIR CURRENTS TEMPERATURE MOISTURE LIGHT SOIL THE ABIOTIC
Section 2.1 Summary – pages Abiotic factors have obvious effects on living things and often determine which species survive in a particular environment. (How?)
Section 1 Check Question 1 Which of the following is a biotic factor? D. light C. earthworm B. soil A. moisture Quickly discuss with the person next to you about: The difference between abiotic and biotic factors
Section 1 Check Question 2 Look at the side board, pick something that isn’t a characteristic of life….explain why. Quickly discuss with the person next to you about: The five characteristics of life and what they mean Question 3 What is the difference between growth and development?
Section 1 Check Quickly discuss with the person next to you about: Responding to stimuli Question 5 Describe a situation in which an organism responds to an external stimuli? An internal stimuli?
