Which famous scientist is associated with the force of gravity?

• Newton

• Einstein

• Galileo

• Mrs. Wallace

A student conducts an investigation to determine how the force of gravity affects different objects dropped from different heights. The student tests each object one time and announces that all objects experienced gravity the same way. What is wrong with the student's reasoning?

• Student didn't test the results multiply times.

• Student didn't create a graph for his data.

• Student didn't share his findings with others.

• Nothing is wrong with his reasoning.

Which choice is the best description of a well-defined, testable question for a science experiment?

• All students get the question correct on the test.

• The question can be answered through experiments and observations.

Select all that apply.

• Reflect

• Refract

• Travel straight through.

How are insulators and conductors different?

• Insulators allow electrons to pass easily and conductors do not allows electrons to pass through easily.

• Insulators do not allow electrons to pass easily and conductors do allows electrons to pass through easily.

• They are the same.

What must all electric circuits have in order to work properly?
