  1. Midterm Jeopardy 1

  2. What are the steps to the Scientific Method?

  3. Observing/Asking Questions • Making inferences/Forming hypotheses • Conducting a controlled experiment • Collecting/analyzing data • Drawing conclusions

  4. Think of an EVERYDAY example In which you use the scientific method

  5. Answers May Vary

  6. What are CONTROLLED variables? Define & Provide Example

  7. Definition: what remains UNCHANGED IN AN EXPERIMENT. • Example: Time, light, temperature, availability of nutrients etc.

  8. Identify 4 of the 8 features of life

  9. Cells are the basic unit of life growth/development obtain and use energy Reproduction response to stimulus taken as a group living things evolve maintain a stable internal environment living organisms have a universal genetic code-DNA

  10. What is homeostasis?

  11. Maintaining a stable internal Environment! HAPPY & HEALTHY

  12. What is metabolism?

  13. The combination of chemical reactions through which an organism builds up or breaks down materials When metabolism stops, An organism CANNOT perform life functions  DEATH 

  14. What is a CELL?

  15. basic unit of all forms of life

  16. Identify 4 of the 8 features of life That have NOT been mentioned.

  17. Cells are the basic unit of life growth/development obtain and use energy Reproduction response to stimulus taken as a group living things evolve maintain a stable internal environment living organisms have a universal genetic code-DNA

  18. Why is it important for cells to have ATP??

  19. All living organisms (auto/heterotrophs) must undergo some type of cellular respiration to produce ATP ENERGY!!!!!!!!!!!

  20. Identify Each!

  21. Follow Up – What are the HONC Elements? How many bonds are needed to make them stable? Hydrogen 1 Oxygen 2 Nitrogen 3 Carbon 4

  22. What’s the difference?

  23. Protons and Neutrons have about the same mass • Protons and neutrons are bound by strong forces which form the nucleus  or center of the atom

  24. Define the following: Atom Molecule Element Compound

  25. Define the following: • Atom: The Basic Unit of ALL matter • Molecule: the structure that results when atoms are joined together by covalent bonds • Element: a pure substance that consists entirely of one type of atom • Compound: A substance formed by the chemical combination of two or more elements in definite proportions

  26. What is the Valence Shell? Or Valence Electrons?

  27. Valence Electrons • the electrons in an atom that are available to form bonds • these are unpaired electrons which are found in the outermost energy level of the atom's electron cloud. • Determine STABILITY and REACTIVITY

  28. Identify ALL: Coefficient Subscript Reactants Products Arrow

  29. Identify ALL: Reactants Products Yield Sign Coefficient Subscript

  30. Why can organisms NOT live forever? What happens??

  31. Over time there is damage to DNA and cells • Wear out, despite constant maintenance and repair throughout the organism’s life time • Cannot always maintain homeostasis in all environmental conditions • Cannot continue its metabolism and maintain homeostasis, its life will cease. • Earth has a limited supply of resources • Death – materials in cells are recycled back into the environment for use by new generations of living things

  32. This is the structural formula for what compound?

  33. Ammonia NH3 Remember to create your structural formulas, determine Bond Availability LOOK AT THE PERIODIC TABLE!

  34. What is the Law of Conservation of Matter?

  35. The Law of the Conservation of Matter • Matter (atoms and elements) in a chemical reaction cannot be created nor destroyed. • Only the arrangement of the atoms is changed. Not the number or types

  36. Determine the Number of Atoms of Each Element

  37. To determine atoms – VIEW THE SUBSCRIPT If a coefficient is present remember to multiply (Subscript x Coefficient = Total Atoms of the Element)
