1 NAME : Block : Notes Page 2-1 SOL Objectives LS 3 The student will investigate and understand that living things show patterns of cellular organization: a)cells, tissues, organs and systems LS 4 The student will understand that the basic needs of organisms must be met in order to carry out life processes. Key concepts include: Plant needs (light and energy sources, water, gases, nutrients, space) Animal needs (food, water, gases, shelter, space) Factors that influence life processes Unit Calendar: Subject to Change

2 Notes Page Which of these has the greatest influence over how big a baby elephant will grow? a. The amount of oxygen in the air b. The amount of food available _ c. The size of the trees in the jungle d. The type of grass on the plains 4. Unlike other animals, mammals can perspire. The main benefit of perspiring is that it A. removes extra water from the cells B. cools the skin with evaporation _ C. removes dirt from the surface of the skin D. relaxes the muscles 2. Rabbits have developed behavioral and physiological strategies to sustain them through periods of environmental stress. Which of the numbered life processes above could be sacrificed without affecting an individual rabbit s survival in periods of extremely poor environmental conditions? f. 1 g. 2 h. 3 j In order to maintain homeostasis, it is most important for an animal to be able to A. respond to its environment B. hide from its predators C. change its habitat D. increase its prey population 5. According to the graph, the highest metabolic rate is found in F. Amphibians G. reptiles H. birds _ J. mammals 6. Plants and animals are similar, in the fact that they both require: A. Sunlight B. Carbon dioxide C. Oxygen D. Shelter

4 A non-living environmental component (ex. rock, water) A living environmental component (ex. Plant or Animal) a requirement, necessary duty, or obligation, an urgent want a distinguishing feature or quality An internal or external event that generates a response Maintaining a normal balance (equilibrium) One cell More than one cell Using food to produce energy or using energy to form a new product Breaking food down into smaller nutrients which can then be absorbed into the body

5 Notes Page 2-4 Use your vocabulary words in your foldable to correctly complete the sentences below: 1. Sally sat in the dirt, an or non living, component of the Earth. 2. Since biology is the study of life, Marvin remembered that factors were the living components of the Earth. 3. Whew! I am burning up! Andrew said on a hot summer day. Since the environment was so hot, Andrews body had to sweat in order to maintain. 4. Paramecium and euglena are both made of one cell, so they are organisms. 5. We can gain energy by obtaining food, BUT before our body can use the energy within our food, it must go through. 6. Ouch! said Molly as she removed her had from the stove. In this example, Molly was responding to a. 7. Randall was full of energy, always on the go, and could eat whatever he wanted without gaining an ounce! Because of that, we all knew that Randall had a high. 8. Explain the difference between Characteristic and Need in a sentence of your own:

6 Notes Page 2-5 Take 10 minutes to notice the nature around you. Life science is happening everywhere and you are a part of it. Record your observations, make sure you describe both the abiotic factors and biotic factors during your time outside. You may use words or pictures for your descriptions. Record at least 2 quantitative observations for each factor. And remember. Enjoy this time!

7 Notes Page 2-6 Don t fill my head with the logic and science behind the phenomenon. Let me bask in it s glow. Let me shake my head in wonder. Let me sit quietly and take it all in with my own senses. Let me accept it as a miracle of life. Tell me about the myths. Share a bit of folklore. Talk with me about mystery The mystery of it's very existance. And you will fuel my belief in God A bright blue sky as far as the eye can see A perfectly spun web covered in morning drops A 12 foot high sunflower which started from a seed I held in my hand Flickering stars on a summer night blending into one another the milky way as far as your imagination can take you Fork Lightening filling the sky with it's wrath Cotton soft cumulus clouds floating in the wind Cascading waterfalls Autumn colours A glowing orange harvest moon rising above the river An intricately designed beaver dam Robin's egg blue A perfectly arching rainbow slipping through a cloud A hummingbird stopping to sip the sugary sweet from the feeder Dawn Dew Midnight blue An intricate snowflake A busy little ant carrying a crumb larger than it's own body Tides rolling in and out every single day Abiotic Factors Biotic Factors

10 Notes Page 2-9 Compare and Contrast: Which needs do plants and animals share? Which needs are different? Plants only BOTH Plants and Animals Animals only Choose Plant or Animal (circle your choice). Draw a comic strip to show the 5 basic needs

12 Notes Page The University of Virginia Medical School is doing a study to see if a new medicine will help reduce flatulence in 7th graders. 400 students were divided into 2 equal groups. Group A received the new medicine; Group B received a placebo (pill that does not contain the medicine). Which group is the control? Why? Describe the following data chart using words in a wellwritten paragraph that includes the word average. Seltzer Water Diet Coke Sprite Orange Fanta Trial 1 1 meter 5 meters 3 meters 2.4 meters Trial meters 4 meters 3.5 meters 4 meters Trial meters 6 meters 2.5 meters 3.5 meters Average 1.1 meters 5 meters 3 meters 3.3 meters 3. Experimental Madlibs: Noun: Metric Measurement: Increase/Decrease/Stay the same: If the is soaked in water for 2 days, (noun) then the will. (measurement) (increase/decrease/stay same) What is your independent variable? What is your dependent variable? What would you use for a control?

16 Notes Page 2-15 Goal #1: I will be able to identify abiotic and biotic components. I will explain the role of the characteristics that all living things have in common. Goal #2: I will identify the control in an experiment. Goal #3: I will recognize the difference between unicellular and multicellular organisms. Personal reflections: school Personal reflections: life
