Answer:
1) Observation: "I've seen that frog eggs in ponds that receive runoff from farm fields sprayed with herbicides hatch at lower ratesthan those unaffected ponds."
2) Hypothesis: "The hatching success of frog eggs is affected by exposure to herbicides."
3) Prediction: "If frog eggs are exposed to elevated levels of herbicides the hatching success of the eggs will decrease."
4) Test: In the laboratory, raise frogs in pond water with varying concentrations of herbicide, and measure hatching successrates.
5) Result: Analysis of experiment data concludes that herbicide levels affect hatching rates.
