STAAR CARDS

1ST 9 WEEKS

CARD 1• 1. Hypothesis = is a specific, testable prediction about

what you expect to happen in your study.– Theory = is a well-established principle that has been

developed to explain some aspect of the natural world. Arises from repeated observations.

• 2. Independent = variable you are changing/experimenting with

Dependent = responding variable due to change. DRY = Dependent, Resonse, Y Axis MIX = Manipulated, Independent, X-axis

3. Graduated Cylinder

CARD 2

• 4. Quick Term Energy, CHO

• 5. A. 2 B. 2 sugars C. Polymer

• 6. long-term energy, CHO

CARD 3

• 7. contains genetic code for an organisms’s traits (AKA proteins). CHONP

• 8. Makes up the function

and structure of an organism’s body,

CHON

CARD 4

• 9. PRO means NO nucleus or membrane bound organelles (MBO), Eukaryotes are larger and have a nucleus and MBO.

• 10. 1. All living things are made of cells2. Cells are the basic unit of life3. Cells come from pre-existing cells

• 11. Cell Wall, Chloroplast, & Central Vacuole• 12. DNA, Cell Membrane, Cytoplasm, &

Ribosomes

CARD 5

• 13. Enzymes are biological catalysts that speed up reactions in our bodies. Ex. Breaking down food. . .

• 14.

CARD 6

• 15. A. Both benefitB. One benefits and one is unaffectedC. One benefits and one is harmedD. Predator hunts preyE. Organisms fight for same limited resources

• 16. Arrow points to where energy is going. Grass grasshopper Mouse Snake

• Energy is decreasing as we move up, 90% is lost as heat and only 10% passed on per trophic level.

CARD 7

• 17. Abiotic = non-living (sun)Biotic = living (tree)

• 18. observed process of change in the species structure of an ecological community over time.

• 19. Primary starts with rock & Secondary starts with soil (caused by fires/natural disasters, plowing, deforestation, etc.)

CARD 8• 20. Gases are being trapped in Earth’s

atmosphere due to increase output of CO2 in carbon cycle. This is increasing atmospheric temperatures in globe, changing weather patterns.

• 21.
