  1. Grade 7 Exam Edition

  2. Ecosystems -10 • List at least 3 ABIOTIC conditions that can effect the kinds of organisms living in an ecosystem:

  3. Ecosystems -10 • Amount of sunlight • Precipitation • Soil conditions • Growing season

  4. Ecosystems -20 • This level of the ecological pyramid uses photosynthesis to produce energy:

  5. Ecosystems -20 • Primary Producers

  6. Ecosystems -30 • These organisms start and then finish the process of decomposition (two different types):

  7. Ecosystems -30 • Scavengers • Microorganisms

  8. Ecosystems -40 • Name these inputs and outputs of cellular respiration:

  9. Ecosystems -40 • Glucose (Food) • O2 (Oxygen • Outputs: • H2O (Water) • CO2 (Carbon Dioxide) • Energy

  10. Ecosystems -50 • These are three ways that humans can negatively impact ecological succession:

  11. Ecosystems -50 • Use of pesticides • Spread of invasive species • Logging and mining • Urban sprawl (lawns?) • Over-fishing • Pollution • Etc…

  12. Earth’s Crust - 10 • The thickest of the Earth’s layers, this layer is mainly composed of silicate rock.

  13. Earth’s Crust - 10 • The mantle

  14. Earth’s Crust - 20 • These three phenomena are attributed to plate tectonics:

  15. Earth’s Crust - 20 • Volcano eruption • Earthquakes • Mountain formation • Continental drift

  16. Earth’s Crust - 30 • This type of rock is formed when little bits of eroded rock are deposited and compressed.

  17. Earth’s Crust - 30 • Sedimentary

  18. Earth’s Crust - 40 • These are two reasons why geothermal energy is considered to be sustainable.

  19. Earth’s Crust - 40 • Renewable • Lower green house gas emissions

  20. Earth’s Crust - 50 • These are four ways that farmers can prevent erosion from wind and water.

  21. Earth’s Crust - 50 • Contour-cultivated hillsides and slopes • Use of gullies and pathways for water movement • Planting cover crops in the fall • Use of a tree line or shelter as windbreak • Minimize tilling • Crop and animal rotation • Planting grasses for animal foraging

  22. Particle Theory of Matter -10 • This is a solution in which no more solute can be dissolved.

  23. Particle Theory of Matter -10 • Saturated solution

  24. Particle Theory of Matter -20 • This change of state happens over a lake on a hot day. Name it and the states of matter it effects

  25. Particle Theory of Matter -20 • Evaporation, liquid, gas

  26. Particle Theory of Matter -30 • List all four methods of separation that we used in the lab.

  27. Particle Theory of Matter -30 • Evaporation, Filtration, Magnetism, Sedimentation.

  28. Particle Theory of Matter -40 • This type of heat transfer occurs in fluids and creates a circuitous current.

  29. Particle Theory of Matter -40 • Convection

  30. Particle Theory of Matter -50 • These are the five points of the particle theory of matter.

  31. Particle Theory of Matter -50 • All matter is made out of particles • Particles in a pure substance are the same • Particles are always moving and they speed up as they gain energy • There is space between particles • There is attraction between particles

  32. Forces and Structures- 10 • These are the three different types of structures.

  33. Forces and Structures- 10 • Solid, Shell, Frame

  34. Forces and Structures- 20 • This type of forces pulls on both ends of a structure in opposite directions.

  35. Forces and Structures- 20 • Tension

  36. Forces and Structures - 30 • These are three external forces that act on a house during the winter.

  37. Forces and Structures - 30 • Gravity • Wind • Snow weight • The ground

  38. Forces and Structures - 40 • These are three different building techniques that can make a structure stronger.

  39. Forces and Structures - 40 • Arches • Trusses • Foundation • Braces • Columns • Guy Wires

  40. Forces and Structures - 50 • If a 200 g bridge can hold a max load of 10 kg, what is its structural efficiency.

  41. Forces and Structures - 50 • .5 kg₂

  42. Grab Bag - 10 • The animal pictured here belongs to this level of the ecological pyramid:

  43. Grab Bag – 10 • Secondary Consumer

  44. Grab Bag - 20 • Tectonic plates are part of this rocky “sphere”.

  45. Grab Bag– 20 • Lithosphere

  46. Grab Bag - 30 • This is an example of what type of solution?

  47. Grab Bag – 30 • Homogeneous solution

  48. Grab Bag - 40 • Name the two different types of lenses used in the device pictured here:

  49. Grab Bag – 40 • Ocular lens • Objective lens
