Scientific Method
What is the first step of the scientific method?
Make an observation
What is a wave?
A wave is a repeating movement or disturbance that transfers energy through matter or space.
What is conduction?
The transfer of energy when two objects are touching.
What is plate tectonics?
Plate tectonics is the theory that the Earth's crust is broken into pieces that move on top of the mantle.
What is a unicellular organism?
A unicellular organism is made up of one cell.
What do you call the variable that is changed in an experiment?
Independent variable.
What is the difference between a mechanical wave and an electromagnetic wave?
Mechanical waves require a medium to travel, while electromagnetic waves can travel through a medium or a vacuum.
What is convection?
The transfer of energy when warmer, less dense fluids rise and cooler, more dense fluids fall.
Name one natural event caused by plate tectonics.
Earthquakes or volcanoes.
What is the function of the nucleus?
The nucleus is the control center of the cell.
Define bias in experiments.
Bias is any systematic deviation between the results of a study and the truth.
What type of wave requires a medium to travel?
Mechanical wave.
Define potential energy.
Potential energy is the energy an object has due to its position in a system.
What are the three types of plate boundaries?
Divergent, convergent, and transform boundaries.
Name the levels of organization in living things.
Cells, tissues, organs, organ systems, organism.
What is the purpose of a control variable?
Control variables are used to ensure that the experiment is fair and that the results are due to the independent variable.
Name the two types of waves.
Transverse waves and compressional waves.
What is kinetic energy?
Kinetic energy is the energy an object has while in motion.
What is erosion?
Erosion is the process by which rocks and soil are moved by water, wind, ice, or gravity.
List three body systems.
Circulatory, respiratory, muscular, skeletal systems.
What are the six steps of the scientific method in order?
1) Make an observation, 2) Ask a question, 3) Form a hypothesis, 4) Test hypothesis/Experiment, 5) Analyze data, 6) Communicate/share results.
Explain how light waves affect our perception of surroundings.
Light waves interact with materials, affecting how we see colors and shapes.
Give an example of a conductor and an insulator.
A conductor example is copper, and an insulator example is rubber.
Explain the process of weathering.
Weathering is the process where rock is dissolved, worn away, or broken down into smaller pieces.
How do cells function in multicellular organisms?
Cells function together by forming tissues that perform specific functions in organs and organ systems.
