Drag the positive or negative feedback loop on the left to each process on the right. Terms may be used once, more than once, or not at all. Positive Negative

1. A snowball rolling down a hill accumulates snow and becomes larger, which increases its speed, causing it to increase its size and speed even more. - POSITIVE 2. Increasing air temperatures from global warming speed up the melting of glaciers, exposing darker rocks underneath the ice. The dark surfaces absorb more sunlight, causing further increases in temperature and accelerated glacier melting. - POSITIVE 3. A dog pants as it lies in the hot summer sun, releasing excess body heat to the environment and lowering its body temperature to its stable state. - NEGATIVE 4. A bull on the edge of a herd of cattle panics when it hears a loud noise and begins to run. Five nearby cattle sense the panic and also begin to run. This causes another 15 cattle to panic. Eventually, all 100 cattle in the herd panic and stampede. - POSITIVE 5. You invest $1,000 in a savings account and reinvest the 5% interest you earn. The interest makes the amount of money in the account larger, so it earns even more interest. After 20 years, the account contains more than $2,600 and is still growing. - POSITIVE 6. When blood sugar levels rise after eating a meal, the pancreas releases the hormone insulin, stimulating cells to take up sugar from the blood. When blood sugar levels drop, the pancreas releases another hormone to stop sugar uptake by cells. - NEGATIVE

Drag each statement under the correct step in the scientific method. Observation > Hypothesis > Prediction > Test (experiment) > Results

Observation > "I've seen that frog eggs in ponds that receive runoff from farm fields sprayed with herbicides hatch at lower rates than those in unaffected ponds." Hypothesis > "The hatching success of frog eggs is affected by exposure to herbicides." Prediction > "If frog eggs are exposed to elevated levels of herbicides, the hatching success of the eggs will decrease." Test (experiment) > In the laboratory, raise frog eggs in pond water with varying concentrations of herbicide, and measure hatching success rates. Results Analysis of experimental data concludes that herbicide levels affect hatching rates.
