  1. 1. Characteristics of Living Things • Identify the characteristic of life shown in the photo. Elephant cooling off in a watering hole on a hot day.

  2. 2. Characteristics of Living Things • Identify the characteristic of life shown in the photo. Plant tissue viewed through a microscope.

  3. 3. Characteristics of Living Things • Identify the characteristic of life shown in the photo. Polar bear protecting her young.

  4. 4. Characteristics of Living Things • Identify the characteristic of life shown in the photo. Lemur eating a cucumber slice.

  5. 5. Characteristics of Living Things • Identify the characteristic of life shown in the photo. Sheep seeking shelter from the sun.

  6. 6. Characteristics of Living Things • Which characteristic of life is defined as: “the tendency of a system, especially the physiological system of higher animals, to maintain internal stability”? • Which characteristic can be described as: “Populations of living organisms have the ability to adapt to their environment. Changes occur in populations, and the organisms in the population become better able to metabolize, respond, and reproduce. They develop abilities to cope with their environment that their ancestors did not have”?

  7. 7. Characteristics of Living Things • One characteristic of living things is the display of organization within their bodies. Give an example of an organ system, organ, and tissue within the human body. Which is the most specific (smallest) level of cellular organization?

  8. 8. Scientific Method • What is the experimental variable in the experiment illustrated to the right?

  9. 9. Scientific Method • Look at the data collected in the plant experiment. Is the data qualitative or quantitative?

  10. 10. Scientific Method • According to the data table, what is the optimum amount of water to be added to the plant?

  11. 11. Scientific Method • Look at the labeled graph below. What is the dependent variable in the experiment? What axis always represents the dependent variable?

  12. 12. Scientific Method • In 1928, Sir Alexander Fleming was studying Staphylococcus bacteria growing in culture dishes. He noticed that a mold called Penicillium was also growing in some of the dishes. A clear area existed around the mold because all the bacteria that had grown in this area had died. In the culture dishes without the mold, no clear areas were present. Fleming hypothesized that the mold must be producing a chemical that killed the bacteria. He decided to isolate this substance and test it to see if it would kill bacteria. Fleming transferred the mold to a nutrient broth solution. This solution contained all the materials the mold needed to grow. After the mold grew, he removed it from the nutrient broth. Fleming then added the nutrient broth in which the mold had grown to a culture of bacteria. What is Sir Alexander Fleming’s experimental problem?

  13. 13. Scientific Method • What is the base unit for measuring length in the metric system? • What is the base unit for measuring the volume of a liquid in the metric system?

  14. 14. Scientific Method • Make the following conversions: • 85.3 cm to hm • 0.34 kL to DL • 11dg to mg • 0.07m to hm

  17. 17. Safety and Lab Equipment • Name the piece of lab equipment shown in the photo.

  18. 18. Safety and Lab Equipment • Name the piece of lab equipment shown in the photo.

  19. 19. Safety and Lab Equipment • Name the piece of lab equipment shown in the photo.

  20. 20. Safety and Lab Equipment • Name the piece of lab equipment shown in the photo.

  21. 21. Safety and Lab Equipment • Name the piece of lab equipment shown the photo.

  22. 22. Safety and Lab Equipment • If you spill a chemical in class, what should you do? • What should you do if your clothing catches on fire in the lab? • Who should operate the fire extinguisher? • Where is our safety shower? • What is the last thing that you should do when leaving the lab? • Name 3 pieces of safety equipment in our classroom.
