Lesson Launcher – Round 3 – 10/18 • 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 organism’s 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. • Organelles carries out a specific task to keep cells functioning. What levels of organization make up organelles? • Atoms – elements-molecules-compounds • What level of organization is being represented in picture A? • Tissue • What level of organization is being represented in picture B? • Cells
2nd section Title: The Cell Theory 1. All living things have cells 2. Cells come from other cells 3. Cells are the basic unit of life At top of page write the following statements and box them. List the following scientists, skipping 3-4 lines between each and take notes during the video. • Hooke • Leeuwenhoek • Schleiden • Schwann • Virchow
The Discovery of the Cell Robert Hooke • looked at thin slices of cork (plant cells) under the microscope. • Named it a cell 1665
Anton van Leeuwenhoek – late 1600’s Leeuwenhoek made many simple microscopes He was the first to: …. see and describe microorganisms ( bacteria, 1-celled creatures) under the microscope. He observed microorganisms in a drop of pond water, dental scrapings, etc.
All living things have cells Cells are the basic unit of life
On the road to the cell theory... Matthias Schleiden Theodore Schwann German botanist Zoologist 1838 1839 Schwann said that all animals are made of cells. Schleiden said that all plants are made of cells.
Matthias Schleiden and Theodore Schwann used evidence gather from their research to propose the first to postulates of the Cell Theory. • All living things have cells • Cells are the basic unit of life
Virchow In 1858, Rudolph Virchow said that cells could only arise from preexisting cells.
The Cell Theory Draw and Color a Cell Theory Infographic: All living things are composed of cells. Cells are the basic units of living things. New cells are produced from existing cells.

Round 4 – Lesson Launcher – 10/28 • There are three main types of rock; igneous, metamorphic, and sedimentary. These rock types are formed in different ways, however because of the rock cycle they are able to transform into one another. A rock that has been transformed from a striated (layered) rock to one that is under intense heat and pressure. What was the rock type before and after its transformation? • Sedimentary to igneous • Igneous to metamorphic • Sedimentary to metamorphic • Metamorphic to igneous • Divergent boundaries are responsible for all of the following landforms except • Volcanoes • Mid-ocean ridge • Trenches • Rift valley • What two layers are responsible for convention currents? • Crust and mantle • Inner core and lithosphere • Core and mantle • Crust and outer core
Second Section Title: Cell Parts • Write down the following Notes • Cells do not have just one of each organelle. Depending on the specialization or purpose of the cell it can have more than one of an organelle. • The mitochondria convert chemical energy from food into a form that cells can useknown as ATP. Mitochondrial DNA isare passed almost exclusively from mother to offspring through the egg cell. • 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.

Wednesday – 10/30 - Materials Needed • Writing Utensil • Notebook • Quiz Friday – Function of the 11 organelles • Objective: • How do cells maintain Homeostasis - Movement of Substances across the cell membrane
2nd Section Title: Various Ways a Cell maintains Homeostasis Write down list in notebook and draw and line under list to section off from rest of notes or box list. • Movement of Substances across the cell membrane • Getting and obtaining energy • Waste Removal • Protein Synthesis • Cellular communication • DNA replication to make new cells (mitosis and meiosis)
2nd Section Title: Various Ways a Cell maintains Homeostasis • Movement of Substances across the cell membrane • Active , Passive, Osmosis / endocytosis / exocytosis • Getting and obtaining energy • Photosynthesis and Cellular Respiration • 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.

Day 1 – Gummy Bear Lab • Obtain cups, two Gummy Bears and a ruler. • Label one beaker with “Distilled water” and one with “Salt Water” • Measure your gummy bear (in cm) from top to bottom (length) and from side to side (width) and from front to back (height). • Record the dimensions in centimeters in the data table (Day 1 Initial). • Calculate the volumes for the two bears (L × W × H). • Find the mass of each bear. Record the mass in the data table in grams. • 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. • Put the 5 grams of salt into salt water cup. • Add 50 mL of water to each cup. • Place one bear in each beaker. • The bears should be completely covered. • Place the beakers on the counter away from direct sunlight and let them sit overnight. • Predict what with happened to the two gummy bears overnight.
Gummy Bear Lab • The next lab day, gently pour the water into the sink without dropping the gummy bear in. • Place on paper towel or waxed paper. • Measure the length, width, and height. Record in the data tables (Day 2 Final). Blot dry by placing bear on a paper towel. • BE CAREFUL not to break the bears, they are very fragile. • Weight the gummy bear carefully find the mass of the bears. Record in the data tables. • Under Day 2 in notebook make observations for both Gummy Bears. • Complete the review questions on ipad. • Lab Questions will be pasted
