What is energy transformation?

Back

Energy transformation is the process of changing energy from one form to another, such as light energy being converted into chemical energy during photosynthesis.

Front

Why is replication important in scientific experiments?

Back

Replication is important because it verifies the results of an experiment. If results cannot be replicated, it may indicate that the original experiment was flawed.

Front

What is the difference between a hypothesis and a theory?

Back

A hypothesis is a testable prediction about the relationship between variables, while a theory is a well-substantiated explanation of an aspect of the natural world based on a body of evidence.

Front

What is chemical energy?

Back

Chemical energy is the energy stored in the bonds of chemical compounds, like atoms and molecules. It is released or absorbed during a chemical reaction.

Front

What is the role of a control in an experiment?

Back

A control is a standard for comparison in an experiment. It helps to isolate the effects of the independent variable.

Front

What is the significance of peer review in scientific research?

Back

Peer review is a process where other experts evaluate a research study before it is published. It ensures the research is valid, reliable, and contributes to the field.

What is sound transmission?

Back

Sound transmission is the process by which sound waves travel through different mediums, such as air, water, or solid materials. Sound travels faster in solids than in liquids or gases.
