A scientist measures the change in temperature from a chemical reaction over a three-day period in a single experiment. When the scientist analyzes the data, the results are five degrees Celsius higher than reported by other scientists after studying the same reaction.
How can the scientist appropriately resolve this problem?

• A.Publish the results as a contradiction to the previous studies
• B.Perform the experiment again
• C.Discard all of the data and report that the results should have matched previous studies
• D.Only include data that matches the results from previous studies

A scientist wants to determine how the speed of flowing water affects the size of sediment particles it can carry. The scientist places a mix of sediment particles in the bottom of a trough and runs water through the trough. The scientist varies the speed of the water and measures the sizes of the particles that the water carries away.
Which type of investigation is the scientist using?

• A.Computational model
• B.Field study
• C.Controlled experiment
• D.Observational study

In which scenario is gravity the force that causes the object's change in motion?

• A.A ball rolling to a stop on the floor
• B.A person running from one end of a room to the other
• C.A bicycle turning when the rider moves the handlebars
• D.A ball falling from a shelf to the floor
