B. Lesson Launcher Round 3 10/18 1. How can a cell be considered a living organism but an organ composed of millions of cells is not considered a living organism? A single cell organism like a bacteria carries out all of life's functions on their own. While a multi-celled organisms cells work together to keep the organisms alive. Each cell is alive inside of a multi-celled organisms but not considered an organism themselves because they could not function without the other cells in the organism. 2.

If Robert Hooke and Anton Van Leeuwenhoek did not propose any of the tenets to the cell theory why are they included in its information? They paved the way for other scientists because they both built microscopes that allowed scientists to view cells. Hooke named the cell. Leeuwenhoek was the first to observe and describe microorganisms. 3. List the 3 tenets of the Cell Theory. All living things are composed of cells. Cells are the basic units of living things. New cells are produced from existing cells. 4. What is the difference between maintaining homeostasis in a multi-celled organisms vs a unicellular organisms? A single cell organism like a bacteria carries out all of life's functions on their own. While a multi-celled

organisms cells work together to keep the organisms alive. 5. Why would removing waste be necessary for homeostasis? If waste builds up it acts as a posion.

Depending on the specialization or purpose of the cell it can have more than one of an organelle. 2. The mitochondria convert chemical energy from food into a form that cells can use known as ATP. Mitochondrial DNA is are passed almost exclusively from mother to offspring through the egg cell. 3. DNA is the primary genetic material contained within cells. It's used to create proteins during protein synthesis, which is a multi-step process that takes the coded message of DNA and converts it into a usable protein molecule.

4. 5. 6. Waste Removal Protein Synthesis Cellular communication DNA replication to make new cells (mitosis and meiosis) Cellular communication There are three basic kinds of intercellular communication used to maintain homeostasis. The first is when direct contact occurs between the membranes of two cells and they signal to each other. The second is when cells use short range chemical signals over short distances. The third is long ranged signals that are secreted into the bloodstream and can be carried anywhere in the body.

food, getting rid of waste, and reproducing. How do cells maintain homeostasis? Day 1 Gummy Bear Lab 1. Obtain cups, two Gummy Bears and a ruler. 2. Label one beaker with Distilled water and one with Salt Water 3. Measure your gummy bear (in cm) from top to bottom (length) and from side to side (width) and from front to back (height). 4. Record the dimensions in centimeters in the data table (Day 1 Initial). 5. Calculate the volumes for the two bears (L W H). 6. Find the mass of each bear. Record the mass in the data table in grams. 7. Before placing the gummies in the cups, you must mix your salt water. Use the triple beam balance and measure a piece of paper. Then, add 5 grams to the triple beam balance and measure out 5 grams of salt until the balance levels out. 8. Put the 5 grams of salt into salt water cup. 9. Add 50 mL of water to each cup. 10.Place one bear in each beaker.

11.The bears should be completely covered. 12.Place the beakers on the counter away from direct sunlight and let them sit overnight. 13. Predict what with happened to the two gummy bears overnight. Gummy Bear Lab 1. The next lab day, gently pour the water into the sink without dropping the gummy bear in. 2. Place on paper towel or waxed paper. 3. Measure the length, width, and height. Record in the data tables (Day 2 Final). Blot dry by placing bear on a paper towel. 4. BE CAREFUL not to break the bears, they are very fragile. 5. Weight the gummy bear carefully find the mass of the bears. Record in the data tables. 6. Under Day 2 in notebook make observations for both Gummy Bears. 7. Complete the review questions on ipad. 8. Lab Questions will be pasted 1. Were your predictions about the gummy bears correct or incorrect? Why or why

not? 2. What happened to the bears placed in distilled water? Why? Be sure to use your data to help explain the result. 3. What happened to the bears placed in salt water? Why? Be sure to use your data to help explain the result. 4. What do you think would have happen to the bear from the salt solution if, they were again placed in distilled water? Why? 5. Explain how this activity relates to homeostasis for the cell. Gummy Bear Lab Distilled Water

Avery did some research about classification for a science report. She learned that until 150 years ago scientists recognized only two groups of organisms: plants and animals. Today, scientists recognize several groups of microscopic organisms. How should Avery explain the reasoning behind why scientists decided to classify organisms into more groups? 1. 2. 3.

4. 3. increased erosion increased carbon dioxide greater oxygen production Greater biodiversity More types of organisms exist now. Fewer organisms have gone extinct in recent years. Scientists continue to learn more about living things. Scientists invent new organisms that need to be classified. How do the temperature and pressure of Earths core compare to the temperature and pressure of Earths crust? 1. 2.

3. 4. The temperature and pressure are lower in the core. The temperature and pressure are higher in the core. The temperature is lower and the pressure is higher in the core. The temperature is higher and the pressure is lower in the core. Label the diagram A. Cool air replaced by warm air that rises from the surface B. Light energy heats surface sand C. Surface sand warms the air above D. Surface sand heats cooler sand below 1. The arrows in the picture below

show several ways heat is transferred from the Sun as it strikes sand on the surface of a beach. Which arrow shows convection? Keely Probe Page 62 The purpose of this assessment probe is to elicit students ideas about the smallest parts of living and nonliving things. The probe is designed to determine how students distinguish between cells and atoms in living and nonliving contexts. Page 80 The purpose of this assessment probe is to elicit students ideas about the plant structure where photosynthesis takes place. The probe is designed to reveal whether students recognize that food is made within the leaf of a plant. Page 86 The purpose of this assessment probe is to elicit students ideas about when the

processes of photosynthesis and respiration occur. The probe is designed to reveal whether students recognize that plants respire continuously. What are other things that students should be looking for when using the science starters for each section? 1. What is the QUESTION ASKING? 1. NOT Question , conclusion on whole graph or a data point, compare information , contrast information 2. What INFORMATION is GIVEN? 1. Picture, charts, Graphs , text 3. What do I KNOW about the TOPIC? 1. Prefixes , root words , definitions, past information 4. What do I think IS THE ANSWER? Go back to the question and determine again what you are looking for and what you think might be the answer. What data matches, what is NOT, etc. 5. What is the BEST ANSWER CHOICE? Look at your answer choices and start narrowing your choices down, always keeping in mind

what the question is asking.
