Electricity
This is the flow of electrical charge.
What is a current?
This class of vertebrates has feathers and lays eggs.
What are birds?
This destructive force wears away rocks and soil over time through wind, water, or ice.
What is erosion?
This type of change alters the appearance of a substance but doesn't create a new one, like tearing paper.
What is a physical change?
Plant cells have this rigid outer layer in addition to the cell membrane, providing support.
What is the cell wall?
This is a closed pathway that allows electricity to flow.
What is a circuit?
This group of invertebrates has a segmented body and an exoskeleton.
What are reptiles?
This type of destructive event can cause rapid shaking of the Earth's surface.
What is an earthquake?
Changing water from a liquid to a solid is this type of physical change.
What is freezing?
Animal cells are often this shape, unlike the more regular shape of plant cells.
What is irregular (or round)?
This device opens or closes an electric circuit.
What is a switch?
This class of aquatic vertebrates breathes using gills and typically has fins and scales
What is fish?
Large ocean waves crashing against the shore can cause this destructive process.
What is wave erosion?
The three common states of matter on Earth are solid, liquid, and this.
What is gas?
This part of the cell is like the "powerhouse," releasing energy for the cell to use.
What are mitochondria?
This type of electricity stays in one place and doesn't flow continuously.
What is static electricity?
This class of vertebrates feeds milk to its young.
What are mammals?
This destructive event occurs when gravity pulls rocks and soil down a slope.
What is a landslide?
When you mix baking soda and vinegar, the fizzing and bubbling show this type of change is happening.
What is a chemical change?
These are tiny living things, often single-celled, that can be found everywhere.
What are microorganisms (or microbes)?
Name a material that allows electricity to flow through it easily.
What is a conductor? (Examples: copper, aluminum, metal)
DAILY DOUBLE
This group of invertebrates has a spiny skin and lives in the ocean.
The movement of this beneath the Earth's surface is responsible for both earthquakes (destructive) and the formation of mountains (constructive).
What are tectonic plates?
The process by which plants use sunlight, water, and carbon dioxide to create sugar and oxygen is this important chemical change.
What is photosynthesis?
These tiny structures within the cell have specific jobs, like little organs.
What are organelles?
