Alfred Wegner hypothesized that when the edges of separate continents are very similar; it suggests that these rocks were formed in the same way, implying that they were joined initially. To prove his hypothesis, Wegner collected fossil evidence from the east coast of South America and the west coast of Africa. Analysis of the fossils showed that they are similar, not only in structure, but in age. His conclusion was that these two continents were once joined. How would you best describe the results of Wegner’s experiment?

• No conclusion can be drawn from the results

• The results fail to support the hypothesis

• The results are inaccurate

• The results support the hypothesis

A students was doing an experiment using the scientific method. Every three days the student plans to count the green leaves. Which would be a good hypothesis for this experiment?

• If plants are placed in direct sunlight, then they will grow more green leaves.

• If plants are places in bright light, then they will grow more green leaves than in dim light.

• If plants are place in clay pots, then they will grow more green leaves than plastic pots.

• If plants are in warmer temperatures, then they will grow more green leaves.

What is the best definition of the term "theory", as it’s used in science?

• What is the best definition of the term "theory", as it’s used in science?

• It is well tested set of ideas that explains events that occur in nature.

• A theory is based on laws that can be proven true.

• It is a hypothesis that has been confirmed

What is the difference between a scientific theory and a scientific law?

• A theory is a well-tested range of representations and a law is a concrete physical representation.

• A theory is a well-tested range of observations of why something works and a law is a well-tested concrete explanation how things work

• A theory is a well-tested range of observations of how something works and a law is a well-tested concrete explanation of why things work

• A theory is a hypothesis that is yet to be proven false and a law is a hypothesis that will always be true.
