Chemical Reactions
This happens when a new substance is formed.
What is a chemical reaction?
This is energy in motion.
What is kinetic energy?
A push or pull.
What is force?
This is the basic unit of life.
What is a cell?
This movement causes day and night.
What is rotation?
This type of change forms a new substance and cannot be easily undone.
What is a chemical change?
This is energy stored due to its position, like a book on a shelf.
What is potential energy?
This law says objects keep doing what they are doing unless a force acts on them.
What is Newton's First Law?
-OR-
What is the Law of Inertia?
This part of the cell controls what enters and leaves.
What is the cell membrane?
This is the layer of Earth we live on.
What is the crust?
In a chemical reaction, atoms are not created or destroyed. They do this instead.
What is rearrange?
The type of energy carried by the light of the sun.
What is radiant energy?
This word describes how fast an object speeds up, slows down, or changes direction.
What is acceleration?
Cells group together to form tissues. Then tissues group together to form these.
What are organs?
This type of rock forms when melted rock cools and hardens.
What is ingeous rock?
When a reaction happens in a closed container and the mass stays the same, it shows this law.
What is the Law of Conservation of Mass?
This type of energy flows through wires to power devices, like your cell phone.
What is electrical energy?
When you push a light object and a heavy object with the same force, this one moves more.
What is the lighter object?
This system sends messages so you body can react.
What is the nervous system?
This force keeps the moon in orbit around the Earth.
What is gravity?
A reaction in an open container seems to lose mass. This is because this leaves the system.
What is gas?
When you rub your hands together and they get warm, energy changes into this form.
What is thermal energy?
When you jump off a boat and it moves backward, this law explains it.
What is Newton's Third Law?
-OR-
What is the law of action/reaction?
These two systems work together to move nutrients from food to your cells.
What are the digestive and circulatory systems?
The movement of these causes earthquakes and volcanoes.
What are tectonic plates?
