What is the first step scientists usually begin with in the scientific method?
What is asking a question or identifying a problem?
This layer of Earth is the thin outer solid surface where we live.
What is the crust?
This is the force that pulls objects toward Earth.
What is gravity?
This is the basic unit of life.
What is a cell?
This organelle is known as the “powerhouse of the cell” because it releases energy for the cell.
What is the mitochondria?
This helps scientists make results more reliable and accurate by doing experiments multiple times.
What is repeating experiments?
This process happens when water vapor cools and changes into liquid droplets to form clouds.
What is condensation?
This happens to the particles of a substance when heat energy increases.
What is the particles move faster?
This process allows plants to use sunlight to make their own food.
What is photosynthesis?
This process in the water cycle occurs when liquid water changes into water vapor.
What is evaporation?
This is a testable prediction, while a scientific theory is a well-tested explanation supported by evidence.
What is a hypothesis?
This is the movement of tectonic plates that can cause earthquakes and volcanoes.
What is plate tectonics?
This law states that matter cannot be created or destroyed.
What is the Law of Conservation of Mass?
This organelle is known as the “control center” of the cell because it contains DNA.
What is the nucleus?
Shiny metal and melting ice are examples of these properties, while rusting and burning wood are examples of these properties.
What are physical properties and chemical properties? Order needs to be said to receive the points.
This is the variable that is purposely changed during an experiment.
What is the independent variable?
This type of rock forms when heat and pressure change an existing rock.
What is metamorphic rock?
This type of energy is the energy an object has because of its motion.
What is kinetic energy?
This system works with the circulatory system to bring oxygen into the body and remove carbon dioxide.
What is the respiratory system?
Tearing paper and breaking glass are examples of this type of change, while baking a cake and cooking an egg are examples of this type of change.
What are physical changes and chemical changes?
This is why a claim is not considered scientific evidence until it is tested and supported with data.
What is it has not been tested through experiments or supported with evidence?
This is the force that keeps planets, moons, and satellites in orbit.
What is gravity?
This occurs when energy is transferred through direct contact between objects.
What is conduction?
This theory explains how species change over time through adaptations and natural selection.
What is the theory of evolution?
This occurs when Earth moves directly between the Sun and the Moon.
What is a lunar eclipse?
