Learning Targets Describe the characteristics that all living things share. Determine whether a virus is considered or nonliving. Identify and give examples of the main classes of Kingdom Protista (Protozoans or Protists). Three main groups: Classify by Plant-like, Animal-like and Fungi-like and for each group find the follow: Metabolism Single celled and or multicellular 3 examples How they move 1 other Distinguishing characteristic

Bell Ringer 8-25-14 THE PEAT MOSS SCENARIO: Norm wanted to know if adding peat moss to sand would affect its ability to hold water. He put 200 mL of pure sand into container A. He put a mixture of 80% sand and 20% peat moss into container B. He put a mixture of 60% sand and 40% peat moss into container C. He put a mixture of 40% sand and 60% peat moss into container D. He added water to each container and measured the amount of water the contents would absorb. He dried the sand and peat moss and repeated the experiment 5 times. He collected the following data. Composition of Mixture Water Holding Capacity (mL) 100% sand 74 80 70 71 74 60% sand, 40% peat moss 86 88 90 92 94 40% sand, 60% peat moss 110 116 104 108 112 80% sand, 20% peat moss 84 82 86 82 84 Hypothesis?

Learning Targets LT-14 Predict whether an object is living or nonliving. LT-12 Using a graphic Organizer of their own students describe the 8 characteristics necessary for an organism to be considered alive.

Characteristics of Living Things

What is biology? The study of living things All living things share certain characteristics

1. Made of 1 or more cells Unicellular (one cell) - ex. Bacteria Multicellular (many cells) - ex. Animals, plants

2. Need energy to survive Autotrophs - get energy from sun Heterotrophs - get energy by consuming nutrients from their environment

3. Respond to stimuli in their environment Stimuli - factors in the environment that living things react to (ex. Light, temperature, sound, etc.)

4. All living things reproduce Sexual - two sex cells required (sperm and egg) Asexual - only one parent cell is needed

5. Grow and develop Each cell divides to make new cells (cell division) – results in growth Some cells become specialized and perform different jobs than others (differentiation)

Learning Targets LT-14 Predict whether an object is living or nonliving. LT-12 Using a graphic Organizer of their own students describe the 8 characteristics necessary for an organism to be considered alive. LT-8 Describe the phenomenon under investigation involving the effects of exercise on heart rate and breathing rate, describing how homeostasis is occurring before, during and after exercise.

6. Maintain homeostasis Homeostasis – a relatively stable internal environment (within a certain range) - (ex. Human body temperature (approximately 98.6 degrees F))

7. Have a universal genetic code All living things have DNA DNA passes on genetic information from one generation to the next

8. Adapt and evolve over time Evolution - gradual change in a population of organisms over time Individuals DO NOT evolve

Bell Ringer 8/27/14 Susie wondered if the height of the hole punched in the side of a quart-sized milk carton would affect how far from the container a liquid would spurt when the carton was full of the liquid. She used 4 identical cartons and punched the same size hole in each. The hole was placed at a different height on one side of each of the containers. The heights of the holes were 5, 10, 15, and 20cm from the base of the carton. She put her finger over the hole and filled carton to a height of 25cm with liquid. When each carton was filled, she placed it in the sink and removed her finger. Susie measured how far away from the carton’s base the liquid had squirted when it hit the bottom of the sink. .
