A scientist observes that a species of deer appears to be changing mating seasons. What's next?

Develop a hypothesis that can be tested.

Which order best reflects the correct order of the scientific method?

observation --> hypothesis --> experiment --> publish result

Which best explains why a student researching should use the most recent version of a textbook?

New discoveries add to older scientific knowledge.

If you test the effects of a new fertilizer on plant growth, which group is your control?

The plant that gets 0 ml fertilizer and 10 ml of water.

Which is a good example of a control group for measuring type of wavelength on plant growth?

Plants grown in normal sunlight.

If I test the effect of a fertilizer on plant growth, which is a constant?

Each plant receives 5 ml of water.

What can be said about the relationship between voltage and current from this graph?

Positive. As voltage increases, current increases.

Which is an observation?

The panda is hanging from a tree branch.

How would you test this question: how far do female sea turtles crawl up beaches when nesting?

Observe the turtles in their natural environment.
