• To replace real-world experiments

• To create more accurate weather forecasts

What does a mathematical model use to represent a system or process?

• Observations

• Numbers and charts

• Equations

• Physical models

In the hands-on lab, how do you predict the weight of the fourth piece of rope?

• Measure the length of the rope using a spring scale.

• Use a graph of the lengths and weights of three ropes.

• Create a new mathematical model for the rope.

• Compare the rope to a sample of the same size.

What improvement allowed forecasts to become more accurate over time?

• Simpler mathematical models

• The use of paper maps and charts

• Faster computers and better models

• Observing animals to predict weather

Why are weather forecasts rarely 100% accurate?

• The calculations are too simple.

• Small changes in factors can affect many other conditions.

• Meteorologists do not have enough training.

• They rely only on past weather patterns.

Why are weather forecasts useful even if they are not completely accurate?

• They provide a general idea of what to expect.

• They focus only on severe weather.

• They always predict extreme events.

• They are based on historical data alone.
